How to repair corrupted sd card?

[noellenchris]

does anyone know how to undelete or repair an sd card? It's happened a few times and I usually format and start over. Any help would be appreciated.

Sometimes the filesystem on the card gets corrupted. It can happen for example if the card was ejected while a file operation on it was in progress. When that happens you might have trouble accessing some of the files, loading times for some directories in file explorer may be very slow.
You can attempt to fix it using the desktop windows' built-in chkdsk utility.
Open up command prompt (start->run->cmd.exe) and type
chkdsk /X /F <SD card drive letter>
My SD card reader is X:\ drive, so i wold use the following command:
chkdsk /X /F X:
SD card reader is recommended, but probably not necessary because it should also work with WinMo's built-in USB mass storage function or wm5torage.

Under linux you can check/fix the card's filesysterm and in some cases undelete a file using fsck.vfat or dosfsck (single tool, two possible names). Refer to its help for more details.

Thanks. I've been looking for this.

If you have problems with your memory card in 80% of all cases the controller of your card is damaged and no software or card reader can help. You must separate the memory chip and dump the raw data to recover your data, look here: CF xD SD memory card/stick photo recovery

I think mine is damaged completely. I will try this.

This worked brilliantly for recovering my files - I rebuilt the BS after copying all the important files (just to be safe)

The card came back perfectly, with all files present.

Donate, because he has done an amazing job.

Recover Lost Data From SD Card

Sometimes it has been seen that you are unable to access the data stored in SD card, in such cases you should use the card in other device and check whether you are able to access the data. If you are unable to do so, then SD card has become corrupt. The possibility of recovering the photos, videos, other documents etc. that are saved in it is by using SD card data Recovery Software. By using this application, you would be able to recover all the data saved in card. In this way, you would be able to recover all your important stuffs saved in SD card.

I have this too at the moment, I've narrowed it down to a corrupted boot sector for myself using testdisk. but most tools don't tools don't allow me too repair/create new partition table. Will post back If I manage to fix my issue

I have had a problem with my SD card. While on holiday in Cambodia and Thailand my camera suddenly said : Card error, while until then I could watch back all my photos. Fortunately I had an extra SD card with me and thought: well, it will be quite easy to fix it when back in the Netherlands. Back home, I tried to open my corrupted card by putting it in the cardreader of my MacBook. I got anxious when my MacBook didn't notice there was a card inserted at all. I scanned all the fora for software to recover my card, but they all didn't find any pictures on it (if they were able to detect the card at all). At that point I decided professional hulp was needed. I sent my card to a company that could restore corrupted data on no cure no pay-basis. I got more worried when I got a message from that company that the problem was really big because the controller was corrupt. Searching for this problem on the internet, I realised that this is a BIG problem. If you want to get it restored it is very expensive and it can take a couple of 100's of Euros to get it fixed (if possible at all). I came across a company on the internet, recoverfab.com , that promised a data restore also on no cure no pay-basis. They described the problem of my card on their website so I sent my card to Germany. Two days later I got a mail that my card had arrived and that they expected to let me know if my data could be restored within two days. One day later, I got an email with a temporaray link to preview the data and how many data were restored. 100% of the files!!! Comparing to other companies this was much cheaper and the service looks great. So once you won't be able to get your card restored with downloaded programs on the internet, the controller might be corrupt on your card, and this CAN be fixed but it is too difficult to do it yourself. I found communication with them very transparant and pricing is more than reasonable and can be found easily on the website. I'm glad that I dare to send my card to another country.

how to fix CRC error on sd card

Hi all,

Hey guys,

So i have a unique problem with my card. It's a 64gb SanDisc class 10. I was creating a backup of my ROM using TWRP when half way through it fails and the phone restarts. Everything appeared to be fine, I could still access everything on the card. Except I can not modify any of the files. If I delete something it will delete without error, even on my computer. But then reappears as if nothing has been touched. I was able to back up the card being that everything is permanently fixed to it. I just can't add, delete, or format anything.

I thought the boot sector was damaged so I used TestDisc to try and rebuild it with no success. TestDisc gave me the same error that the chkdsk X: /R command gives me. "The /system.ext4.win entry contains a non valid link." and "The size of the /system.ext4.win entry is not valid." I don't mind loosing the data by formatting it. I just want to use my card again. Any help is much appreciated.

same happened with me, i was taking a nandroid backup when twrp rebooted which left some kinda write protection in my microsd card due to which i am notable to format/delete or debug the microsd card via chkdsk command. When i use sdformatter to format it says sd card is write protected. When i run chkdsk it shows error in that exact twrp backup file which was created while twrp backup which was left unfinished so there no doubt about the origin of this problem. Any help regarding this would be appreciated

SD card corrupted

Hi, I'm Note 4 user today I've installed newest ROM of eRobot i've configured the phone settings and other stuff, and meantime the albums from gallery was disipeard ....then I checked in settings at storage I've got message with SD card corrupted(see picture below). I turned off the phone I pull out the sd card and used on other phone and on my pc and I realized that sd card it's fully functionally with all files on it.
So what can be the problrm? I guess it's something related with this vs of rom... there is a way to solve this problem? some commands from rom...
thx

Lol, I tried everything, now last resort is claiming warranty, I have a strontium card which has a lifetime warranty, I'll send this one to them and they'll send me a new one, hopefully [emoji28]

Testdisk didn't work

Hi. My computer is not detecting my micro sd card (inserted with an sd card adapter) and I downloaded the Testdisk program and it didn't detect my micro sd card. Althought my computer detects a flash drive that is also corrupted or damaged, the Testdisk program didn't want to recover my files. It said something like: Select another folder.

People all over the internet tries to help giving advices and recommendations about this subject and non of the softwares that are recommended in this situation work for me. The cmd.exe, chkdsk doesn't work because cannot detect my micro sd card; Testdisk didn't work because didn't detect my micro sd card either; I read about another software called like EaseUS and didn't detect my micro sd card; I saw a video in youtube that the man in the video recommends to buy 70% rubbing alcohol (something like that) and put in a soft cloth and rub it over the disk metal (you can see in the video: SD Card,micro SD card Not detected .Quick tip ) and althoght I tried that solution it only worked with sd card adapters that weren't working before. I rubbed my micro sd card several times with that kind of alcohol that I boutght after I watched the video and my computer still doesn't detect it.

I WONDER WHAT IN THIS WORLD CAN HELP MY COMPUTER DETECT MY MICRO SD CARD (and even my flash drive. I kept it for 4 years and half just in case I can recover my old files from there, too but.... )
All that I would like to do is to whether recover my files from both disks or for my computer to detect them again.
Thanks

Method 3:
From diskpart.
list disk -> select disk 1 -> clean -> give Data error <cyclic redundancy check>"

Method 4:
From EaseUS partition manager: format - create partition primary - wipe data ---- Nothing is working.

Method 5:
chkdsk
