Multiple issues with Windows Backup VHD
Posted: Sat Aug 01, 2015 11:00 am
Hi everybody,
seems R-Studio does not handle correctly VHD generated by Windows Server Backup (2008 R2 tried so far).
I tried to recover a damaged VHD, but after getting wierd results I scanned a working one, and found out R-Studio does not handle it neither.
R-Studio does not recognize the virtual device ("msft virtual disk 1.0") nor the partitions.
On a working VHD with a single NTFS partition (starting at 64 KB offset) R-Studio:
- "find" about 50 partitions, all of them with wierd partition offsets like "-10 GB" (yeah, minus, it's not a typo)
- find a lot of "extra found files"
- never recover a file correctly: even when it claims so, file content is wrong (ie supposed Office document file contains executable headers)
Files are recovered correctly using "raw files" search (of course loosing filename and folder).
It seems R-Studio is able to detect the directory structure, but extracts the file content from the wrong disk sector.
Also it get confused from a 100 GB VHD which contains a 300 GB device/volume (Windows Backup does it this way. A 300 GB volume is saved to a file as big as the actual used space).
Is there a way to recover Windows Backup VHD?

Corrado
