CHKDSK corrupt my vhdx file to 0bytes

Maciej · Jun 8, 2022

Hello,
I got massive problem with copy of my parents PC.
I made vhdx of their pc to vhdx, then few days later when I tried to turn it on to update files on it, I got message that File might be corrupted or unreadable. So I found solution online that CHDSK /f would fix my problem. And for worst my parents pc just get broken. and right now our only option is to fix that vhdx. After CHKDSK /f all vhdx with 1TB storage is 0bytes. I tried using recovery from EaseUS but even there my file shown as 0bytes, some of the files shown as "Lost Files" but most important files are not showing in that report and can't recover them. Is there any way to recover it? Most important for me it's to recover files with parents company tax, employee info.
Thanks guys for any help.

Unfortunately you've come across the one big downside of chkdsk - it's actually a pretty dangerous tool when used on a badly damaged drive.

Chkdsk, when run with the /f flag, has one job - detect file system errors and attempt to fix them. Chkdsk is not an incredibly smart tool - all it will do is try to fix the errors it finds. This is often at the expense of having to either move data around, or in some cases remove data entirely to achieve its goal. It can occasionally recover corrupt data, but even then it often is only able to perform partial recovery.

Performing chkdsk on a failing drive can also put a lot of extra stress on the drive - it's not particularly uncommon for a drive to be dying and a chkdsk run pushing it over the edge and killing it.

I know it's little use now, but chkdsk in repair mode should never be run on a disk without performing a full backup first for the exact reason you've seen - sometimes the fixes performed can cause harm in other ways.

Sorry to say there's very little you can do here if you don't have any backups of your data before chkdsk ran. If the data is absolutely essential (and if it is, you really should have been backing it up), you need to stop using the drive immediately and discuss your situation with a data recovery company.

Note this is essentially the same post I made in this thread: Check Disk shuffled the files on the entire disk.
