Windows 7 "Scan and Fix (Recommended)" corrupted my MicroSD card

(1/4) > >>

duugg:
I went out for New Year Eve, had a wonderful time and took many pictures. Upon reviewing my pictures, I noticed that about half of them were a blank icon with a lightning bolt in the top center. I was very upset about this, but said to myself "well, at least I have half of my pictures".

Then  I took the microSD card out of my phone and put it into a card reader and plugged it into my Windows 7 computer.
Upon doing so, I got the message ".......Scan and Fix (recommended) with the option to continue or cancel. I chose continue and all my pictures were deleted from New Years Eve. Ironically, all of my other pictures remained intact and available.

I downloaded and tried more than 15 different data recovery software programs and it only found files that I had already copied; no files from New Years Eve.

I read somewhere that there might be a place where the pictures may be in a hidden file system area under a different file extension and that all I had to do was change the file extension and I would get my pictures back.

Well, after a thorough search, I came up with no files.

I've been reading about "dirty bits" and ran "CHKDSK" from an administrator command prompt typed "fsutil dirty query e:" and it does say that the volume is dirty. I don't want to clear the dirty bit by formatting my microsd card because I will hurt my chances even more of recovering my files. I spoke with Microsoft for over an hour today and no one seems to know about "dirty bits". I believe I read that clearing the dirty bit MAY allow me to see and recover my pictures, but I won't know until I can make that happen.

The file system on the Sandisc microsd 64GB SDHC card is ExFAT and the operating system I tried this on is windows 7 64bit Ultimate . I also tried to recover these files from my Samsung Galaxy S4 and had no luck either.

The worse thing is that I DO use Google backup for my pictures, but I had just factory reset my phone THAT day and hadn't yet had a chance to set it up :)

If anyone knows of a way to restore my beautiful, priceless pictures from New Years Eve, I would be extremely grateful.

Thanks so much to anyone that can help a very sad person who's new year didn't start off the right way.

So sounds like your microsd card has bad sectors on it and is why you are having so much trouble.

Are you able to put the card into your system (If you have a card read) so that you can do a chkdsk on it? OOr if your camera will allow you to scan it while plugged in.

Here is an example,

You have the card plugged in and it gets a drive letter of E: (Just as an example)

Then you open a cmd.exe window as administrator, then type this in

chkdsk E: /f /r

and hit enter and it will do a file system check and repair and also scan for any bad sectors and try to recover any data that it can.

Also, time to get a new sd card :wink:

I know that there are a lot of different parameters used with chkdsk, but I'm not sure if I tried those or not. I will check that when I get home. Thanks much :)

Shane:
/f is to fix any errors it finds
/r will scan all the sectors and try to fix them, much longer scan.

Normally you dont need /f when using /r, but I am just use to always putting /f with it lol

ok, so I got the message "Chdssk cannot run because the volume is in use by another process.....Would you like to force a dismount of this volume (Y/N).

I selected Yes and now says "Windows is verifying files and folder" and is doing its magic.
