Why the phone cannot read the sd card and how to solve it « how-to geek forums

Sometimes the users of SD phone will get in the trouble that the phone cannot read the card even after a few times plugging. Check the following situations to see what the problem is:

(1) SD chip is dirty.
Because of the careless protect for chips, sometimes there will be dust or dirt.
Discrimination; check that if the metal area is black or there is any spot on it.
Handling: use cotton with alcohol or water to wipe it gently. Plug it in when it gets dry.

(2) Battery voltage.
Some good-qualified card requires stable power supply, and the bought battery is not good enough as original battery, so that may cause the problem.
Discrimination: when using the bought battery, if the state of stand by is not good, it may be the problem of battery.
Handling: Change the battery.

(3) The slot is squeezed.
The design of slot is very delicate of some ultrathin devices. If the thickness of battery exceeds certain requirement the slot will be squeezed.
Discrimination; Change the battery to the original battery.
Handling: Use the original battery. Use something to reshape the slot.

(4) The wires inside of the slot rust or bend over.
Some phones support hot-plug, and frequent plug-in and out makes the wires bend over.
Discrimination; Check the slot under light if the wires are at the same position.
Handling: Try to bend the wires back.

(5) SD card gets virus.
For some smart phones, if the SD card gets virus on the computer, it will not be read on the phone.
Discrimination; Scan the SD card on the computer.
Handling: Format the card on the computer or some low specification storage (such as camera). If format it on the computer, you should choose FAT form but not FAT32 form.

(6) SD card is formatted improperly
As the forms of phones and computer formatting are different, redefine the file form and format the card again as the introduction. Please be sure the form of card is FAT, because FAT32 won’t be read in E680.

(7) SD card is broken.
It is very easy to judge. Plug the card in the card with card reader. If it can be read it is all right.

(8) The phone is broken.
If it is the problem of the phone, send your phone to repair.
Hope these advices can help you.

Don’t lose your precious data

Having trouble with your SD card? SD cards can fail for many reasons. Fortunately, there are steps you can take to remedy the issue. Here are some of the things you can do to get your SD card back in working condition.

You’ve been putting the blame on your SD card. But what if the problem lies in the card reader?

Check the Card Reader

Why the phone cannot read the sd card and how to solve it « how-to geek forums

If the card only fails on one specific device, it could very well be a card reader problem. Sometimes built-in card readers in computers need to be repaired or replaced. Inspect it and see if there’s any physical damage. Use a spare SD card to test if the card reader can’t detect any card that’s plugged in.

If you’re using an external card reader, you can try replacing the cables with a compatible substitute. Faulty cables can cause card readers to stop working properly.

Use a Different USB Port

Some computers have more than one USB port. Check your computer’s I/O. If there are USB ports on both front and back panels, try making the switch.

If the card reader works on one port but not the other, you could be having a USB port issue and not an SD card problem as you originally thought.

You may also want to look into swapping the USB cable with another one.

Restart the Computer

An oldie but a goodie, rebooting the computer is a time-tested solution that surprisingly resolves most issues that users encounter. Disconnect the card reader then reconnect after restarting. See if the problem persists.

Update the Drivers

Most USB card readers automatically install drivers when you plug them in for the first time. However, manufacturers would often update their drivers to fix bugs or make improvements to their product. These updates are made publically available for download but would often go unnoticed.

Check with your card reader’s manufacturer if there are updates available and install if there are any. See if that will get rid of the problem.

Check My Computer

If the USB drive is not recognized and no drive letter is shown in My Computer, it’s possible that your computer is low on memory. Try closing all programs and have it run idle for a few minutes.

Alternatively, you can use Task Manager (Windows) or Activity Monitor (Mac) to force stop memory-intensive applications.

If no new drive letter is showing up when plugging in a USB card reader, you may have to manually give the drive a letter using Disk Management.

Turn Off Write Protection

If your SD card is recognized but you’re having a hard time modifying files, you simply may have read-write protection turned on. Memory cards have a physical toggle located on its side. You may have accidentally turned it on during handling.

Why the phone cannot read the sd card and how to solve it « how-to geek forums

Disable read-write protection and see if that fixes the SD card problem.

Format for the Right Device

Formatting an SD card or micro SD card will remove all its contents and somewhat restore it to its original state. However, there are format settings that can affect what devices can read the SD card. It’s possible you may have formatted the SD card to work on computers and not on smartphones, for example.

To make a card readable in your preferred device, you’re going to have to reformat it again. However, do keep in mind that it would erase all the files that are currently on your SD card. Formatting should only be done if you’re comfortable with losing all your data. Otherwise, you’d be forced to use data recovery software.

Hopefully, one of the tips above gets you access to the data on your SD card. If nothing has worked, there could be a problem with the SD card itself. Try it on different computers and devices and if none of them can read it, you may have to use third party data recovery software to pull data off.

SD cards are a great for storage of digital media, like photos or video clips in digital cameras, camcorders, MP3 players, and phones. Below are some of the reasons these cards may not work with a computer.

Test the SD card

If the SD card works with your device (e.g., can see pictures on the camera) but doesn’t work with your computer, it’s safe to assume the computer card reader has problems. A temporary workaround would be to connect the camera, phone, or another device to the computer using a USB cable with the SD card in the device. Once connected, you can transfer the data from the device to the computer without using the SD card in your computer. Skip to checking the USB adapters to start troubleshooting and finding a more permanent solution.

If the SD card does not work with your device (e.g., camera) and isn’t recognized by your computer, the SD card may be bad. Skip to check write-protection to start troubleshooting SD card related issues.

If your smartphone cannot read an SD card, the card may have been formatted by a device that’s incompatible with your phone’s operating system. If you’re experiencing this problem, visit your phone manufacturer’s website for support.

Built-in memory card reader

Some laptop computers and desktop computers have a built-in memory card reader. The memory card reader may not be working properly and causing it to not read the memory card.

If you have access to another memory card, insert it into the computer reader to see if it can be read. If it can be read, your memory card is bad and likely needs to be replaced. If the other memory card is also not readable by the built-in memory card reader, it is a string possibility the memory card reader is not working. You would need to have an authorized service center look at and repair or replace the memory card reader in your computer. You can also try using an external USB memory card reader instead.

Checking the USB adapters

Why the phone cannot read the sd card and how to solve it « how-to geek forums

If you are trying to access the SD card using a USB card reader that connects to a USB port on the computer, try the suggestions below.

Use back USB ports

If you have a computer with front and back USB ports and the reader connects to the front ports, try using the back USB ports.

Disconnect and reconnect USB cable

Make sure the USB connector is securely attached to the USB port. You can verify its connection by disconnecting the USB connector and re-connecting it to the USB port.

Also, make sure the USB connector is securely connected to card reader as well. If this connection is loose, it can cause the card reader not to work properly or at all.

Disconnect and restart computer

Disconnect the USB connector, restart the computer, and then re-connect the USB connector to the USB port. Sometimes this resets the connection and allows the device to work properly again and read the SD card.

Install available drivers

Some USB card readers may have drivers available on the manufacturer’s website. In most cases, Windows does automatically detect and install standard drivers, but some card readers may work better with drivers designed specifically for that device.

Test different types of digital media card

If your USB card reader is capable of reading types of digital media cards, try reading a different card to test the reader. If more than one card cannot be read, then the USB card reader may be defective and unable to read SD cards.

Press the card in a little harder

With some card readers, the SD card may have to be pressed in a little harder. Do not force the SD card into the slot, but try pressing in a little more than you normally would to make sure it is firmly inserted into the slot.

No drive icon in my computer

After inserting the SD card into your card reader, if there’s no drive letter in My Computer to access the SD card, the computer may be low on virtual memory. To resolve this issue, close all open programs and allow your computer to idle for a few minutes. Plug in the SD card again and see if the drive letter appears.

Also, if your computer has Windows Vista, you may need to download and install a patch to fix a known bug relating to issues with reading SD cards in Windows Vista.

Check write-protection

Why the phone cannot read the sd card and how to solve it « how-to geek forums

Many SD cards have a feature called write-protection toggled on and off by a switch on the left side of the SD card. With write-protection enabled, files cannot be modified.

If your SD card has a write-protection switch, make sure it’s disabled, or in the opposite direction that points to “LOCK” on the card. Then you can try using the SD card again and see if this fixes the issue.

Formatting

With some card readers, the card is formatted much like how a disk drive is formatted when first used in a computer. In some cases, the device may format the SD card in a way that makes it only readable by that device and nothing else.

If you have trouble getting an SD card to work with your smartphone, the card may be formatted in a format your smartphone doesn’t support.

If both the device (e.g., camera) and computer can read the SD card, the computer can access the media regardless of how it is formatted.

A potential fix would be to format the SD card to make the card readable again, but keep in mind that this erases the card. Formatting should be done as a last attempt at getting the card to work.

Replacement

If the above solutions do not work for you, it may be necessary to purchase a new SD card as a replacement. Like any storage media, SD cards fail over time, depending on how much use it gets and where it is used. Extensive use or harsher environments (extreme temperatures or humid climate) can result in SD card failure.

Unfortunately, I removed my Garmin Edge Touring from the PC (Windows 8)
while Garmin Express tried to perform a software update . ooops.

The Edge Touring itself works as usual,
but the PC does not recognize the Edge Touring as a USB device any more.

Does anyone have an idea on how to solve this problem ?

Try this
1) Remove the Memory micro SD card
2) Connect the device to the PC
3) Wait till it connects
4) Insert the SD card

Works every time for me. I think it is done to buggy software and a timing issue with the device trying to read the SD card while negotiating the USB interface.

SD cards take an irreplaceable spot in the modern lifestyle, providing more space for storing photos, videos, music and other types of important files.

But nothing lasts forever SD card may get corrupted.

A lot of questions in your head have arisen: How do you restore a corrupted SD card? How do you back up a corrupted SD card? How do you access a corrupted SD card?

And for those questions exist plenty of good answers.

Tips for reading a corrupted SD card

If you want to recover a corrupted SD card, it’s best not to format it. Otherwise, you can lose documents permanently.

The following tips will help you to retrieve data from an SD card without formatting:

1. A fairly common problem is the incompatibility of the SD card with the card reader. Try connecting the SD card with a USB card reader or another computer.

2. Reinstall the driver. Due to driver damage, your computer may not be able to read the SD card.

3. If your operating system does not recognize an SD card, try to manually re-assign a new drive letter for the SD card. Otherwise, you may think that the data on this SD card is corrupted, when it’s probably not.

4. You can try the command line. How do you recover corrupted an SD card using the command line? With that method, you can repair a file system on the corrupted card. But you can’t recover photos or other files from a corrupted SD card or other disks.

5. The simplest one:

  • Unplug and reinstall the SD card.
  • Open “Settings” and then click “Storage.”
  • Under your SD card, select “Disable SD card/ Unmount SD card”.
  • Then turn off your device. Remove the SD card. After a while, insert the SD card again and boot the device. There is a chance that now you will see your photos, videos and other important documents.

If none of these tips helped, then most likely your SD card has been corrupted. However, there is no need for despair. There is another way that will definitely help you to recover files from a corrupted SD card. This is card recovery with software.

According to the latest stats from the Google Developer portal Android 4.4 KitKat currently occupies 13.6% share in the overall distribution of different versions of the operating system. It’s really unsatisfactory given the fact that it’s has been almost seven months since KitKat was first released. While KitKat is known for better and faster performance that the older Jelly Bean, the former is also known for taking away some good features that we used to enjoy on the latter.

With the KitKat update, Google brought a not-so-pleasant thing by revoking the write capability to external SD card by app on an Android device. You must have seen the Move to SD card option under individual app settings on Jelly Bean. It simply means that KitKat does not allow apps to write/move data on the micro SD cards on devices that support expandable storage. If you install too many apps, your phone’s internal storage might fall short as all app data will be stored to it.

Actually, Google removed the write access to the external SD card by apps deliberately for security reasons. Google made this move to stops apps from dumping files everywhere on the card. On Kitkat, all 3rd -party apps can only write to files and folders that they have created or have taken ownership of.

As you know, Android is a world of possibilities. If you have have obtained root access on your device, you might obtain a solution for almost all such issues. The Play Store already has a couple of good apps for fixing write access to extSD card by 3rd-party apps.

While these apps work great on certain devices, the have proven to be ineffective on others. If you have root access on your phone or tablet and having this issue, you can easily fix write capability to external SD card on KitKat manually.

Fix Write Capability to External SD Card Manually

  1. Download Root Explorer or Root Browser or any other root file manager from the Play Store: [googleplay url=”https://play.google.com/store/apps/details?id=com.jrummy.root.browserfree”] [googleplay url=”https://play.google.com/store/apps/details?id=com.speedsoftware.rootexplorer”]
  2. Also install BusyBox on your device, then open the app and install BusyBox script: [googleplay url=”https://play.google.com/store/apps/details?id=stericson.busybox”]
  3. Open the root file manager app. Grant it root access if it prompts you to do so.
  4. Now navigate to /system/etc/permissions/platform.xml
  5. Tap and hold the platform.xml file and select Edit option.
  6. Now look for this entry:
  7. Now add the following string of code just after .
  8. To get a clearer idea, take a look at the screenshot below:Why the phone cannot read the sd card and how to solve it « how-to geek forums
  9. Having editing the file, save your changes and exit the root file manager app.
  10. Finally, reboot your phone or tablet.

When your device boots up the write access on external SD card by third-party apps should be enabled. Enjoy!

I have an Android One phone. I put a bunch of music on the phone, filled up the internal storage.
I then put in a micro SD card, and selected to add this as internal storage (not removable or whatever the other option was).
The phone copied the music to the new card, and failed to delete from the original SD card.
Then the phone created an alias in the file system, pointing the music directory at the new card.

The original (internal hardwired) card is still full, but I can’t delete the music folder because I can’t access it.

I tried a few of the top rated file manager apps, they only allow access to named folders (“music” is one, but it’s aliased to the new storage card), and no direct access to the original internal storage.

I’m a developer, so I am prepared to use ADB or whatever, I just need to know how to gain access to the real underlying internal SD card file system.

The phone isn’t rooted, and the root app I tried didn’t succeed. Possibly this is not helped because the phone is fully up to date security wise.

Depending on which version of Android the phone has (and what other changes the manufacturer and the carrier/service provider made to it) you should be able to go into the following and change it back. Some of the wording may be different on your device, but it should be in this location.

  1. Go into “Settings” and then “Storage”.
  2. Now locate “SD card” in the list.
  3. When you tap that it should allow you to change the card from “Internal” back to “External” storage.

Again, there may be an extra step or two in there. I am not looking at your device, however it should be there.

Once done then the phone should reboot. Just make sure there is nothing on the card at all, as anything on it will not be when it is done as the card should wind up formatted during the process.

Sounds like the phone didn’t actually make the SD card “Internal” storage (or not correctly) and instead of moving the files to the card, it just created copies, which often won’t let you access or delete the originals. It is a flaw with some phones I have run into before.

The only fixes I have found are to either move the files back to the phone, if it will let you, and then return the SD card to “External” storage. Once done, then leave the card as “External” storage (doesn’t need to be changed for just files) and move the files over to the card. It should then not leave a copy on the phone. If you make the card “Internal” storage again, it will likely do this again. Or, if the files won’t move back, then you may need to “Hard Reset” the phone. Which I would suggest be only a last resort.

Try to remember that when you make a card “Internal” storage is what caused the issue. It is not needed for files (images, music, etc.) only for apps that won’t work from the card itself. The card is also encoded when it is changed over, so it isn’t accessible from other things.

NOTE: Before doing any of this, I would suggest you make a copy of the music (if you haven’t already) to another device, computer, etc. This way to don’t risk losing it all.

I have turned off device encryption as you said. When I insert SD card in my phone there is neither any content showing nor adding,while when try to create new folder ,showing simply error. And in storage app,there is not showing any SD card ,while only phone memory is showing.

Bitlocker and its decryption option shows only when insert SD card in laptop/PC.
