Default Corrupted SD card - RAW files

Hi,

My wife and I both have the same type of smart phone - LG G5 which has a nice camera ... recently been on holiday, so bought extra memory for the photos. Now both micro SD cards have failed.

I've tried chkdsk and get the message that the type of system is RAW and chkdsk is not available for RAW files.

Any ideas on how to proceed?

Thanks
PB

I haven't used this, but it looks promising:

Thanks for the link Peru.

The saga continues ...

On the 1st SD card ... I did run chkdsk ... /f ... again on a different computer ... this time it resulted in finding a lot of entries with non valid links ... ended up with a folder called LOST.DIR ... I imaging these are the pictures, but no file extension, most small is size 32kb, but then a lot are 3000kb - 6000kb in size ... no file extension that I can see.

Is there any way we can turn these back into pictures?

On the other SD card, there appears to be nothing ... not sure if my wife did format the card ... If so, can the data be extracted?

Thanks
PB

Up date ...

I copied all the files to a new folder (duplicate) and renamed one file as jpg extension (to see what happened) ... it worked. Renamed one of the larger files with mov extension ... That worked as well.

I guess you could use other extensions, but those were the first that came to mind.

There were loads to rename, so looked for a solution to do a lot at once ...

From the website ... and it worked a treat.

How to convert a batch file (.bat) to .exe executable file

Use these commands in your batch file:

@echo off

ren * *.jpg

This batch file essentially says: "Whatever the filename is, rename it and add .jpg to it on the end."

The asterisk (*) in the batch file acts as a 'wildcard character'. The first variable is specifies the files you want to rename. By just using the asterisk, the batch file works on file with any filename.
The second variable specifies what to rename it with. By using *.jpg , it means, add .jpg to the end. If you wanted to rename the file to add something in front, add that in front of the second asterisk.

Sorry a bit late replying but haven't been able to pop in for a while.

I once had a similar problem to this but mine was just down to being careless. ie, last day of a holiday and sat a table having a drink, placed my phone on the table then when we got up to go I knocked my phone across the room. Back flew off battery came out. The SD card was corrupted and two weeks photos gone.

I tried all the well known and popular recovery software including the one Peru suggested. They all returned limited results plus the quantity recovered file did not amount to the total I knew was on the card. After much searching I found this one, 'ZAR X' which specialises in image recovery from flash drives such as USB sticks and SD Cards, Plus this version is free but it will only recovery photos.

https://www.z-a-recovery.com/tutoria...-recovery.aspx

I recovered every image about 150 of them perfectly in one hit except for one and I think ZAR X is a bit of software certainly worth keeping a copy just in case.

You do need to be patient though it took around 2 hours for it to complete the recovery, but even two hours is probably easier and quicker than manually sorting out partly recovered files.
