Hi there.
I have a big problem. After a serious harddisk crash i lost all data.  I have filebackup of all data except the mailfile. I have a backup of the directory where the vmdk and related files are stored. but the last vmdk backup has somehow gotten corrupted. Any thoughts to how i can get data back from the corrupted vmdk? I have tried:
- Mounted the file in Workstation 7 - so i can acces it in the host os.
- Mounted the file in vdk32.exe - so i can acces it in the host os.
- Mounted it in another workstation 7 virtual pc as a second harddisk and tried to browse it in a virtual pc (windows 2008 servers).
- Used R-studio and some other harddsik recovery programs to scan the disk in the above but with the same results:
    It seems that the 80gig vmdk file just contains 10 gb of data - it should contain over 60gb of data. Rstudio and scanned programs show that the harddisk (vmdk-file) contains the first 10% as data end the rest is blank).
When i browse the vmdkfile via hostpc it contains files but only about 10 gb.

The filecopy was done manually when vmware was shutdown and it completed ok. I took a test and booted the backupvmdk after copying it, and it booted ok - i could log on the virtual server.

Any tools or tips to fix this vmdk-file? I have tried vmware converter as well...

Are there other VMDK files in your backup? Specifically snapshot files?  Other than some outright backup failure or corruption, I do not know why an 80Gb machine should reduce to 10Gb. That is why I ask about snapshots.

There are no snapshots or other vmdk files. I have used an older vmdk-backup so the server is online again, and had filebackup so everything is back except 6 weeks of mail.

Those files are the correct files.  So then, something must have happened in the backup process at some point that affect the .VMDK file.  I cannot see what else at this point. ... Thinkpads_User

Also, 80Gb is a very big file to back up. Is there any chance you had a space error on backup (run out of space)? I would think you would get a message, but it is worth checking.

Also, again because of size, the backup could have choked, but again I would expect an error in the log.

Thanx for tips.
No diskspace error or copy error.
When i copied it I booted the backup vmdk and it booted fine and everything seemed ok - i even loged on as administrator so i could shut it down. Now i miss alot of windows systemfiles (andother files) and cant boot thebackup vmdk. Get the error: "A disk read error occurred. Press Ctrl+Alt+Del to restart".
I can see 10gb of files but miss 50 gb of files when i mount the disk.
Very strange.
I guess the file got corrupted after i shut it down. I hoped it was a way to scan the file for 'files'.
Like a program like R-studio but made for vmdk.
Or maybe the vmx or vmxf files contains some info that make this error.
