HDD is suddenly RAW filesystem and not accessible - Vista Business

Several weeks ago I went to access a secondary SATA drive on my Vista box to pull some images. When I clicked on it the error came up stating it was 'not accessible'.

The drive will not format, read, write or anything that I can tell. It shows as healthy in disk manager, but RAW file system instead of the NTFS it was formatted in.

Any help in recovering this data would be tremendous.

Thanks,
Chris

Try changing the SATA cable first. If no improvement, GetDataBack for NTFS should be able to recover the data. Download the demo to view, buy to recover. Avoid chkdsk. It may recover the file system but is likely to destroy the files.

after the recovery, you may try to convert the file system from device manager.
 if this is not possible, use the disk utilities from  : http://www.tacktech.com/display.cfm?ttid=287
to test and initialise your disk

I removed the HDD from the existing computer running Vista on a PCI based SATA card.

Inserting it into an XP machine with a MB based SATA port rendered a CHKDSK on boot. When theboot was finished it 'installed' the new HDD and required a restart...on the second restart it again rendered a CHKDSK and was working in a different area.

Upon this reboot the drive was seen and accessible and I was then able to plug it back into the Vista machine with the PCI SATA card and recover/move everything to a new drive.

It appears as if a PCI based SATA RAID card or otherwise can in fact corrupt the HDD and change it to the RAW filesystem. This would be accessible by some software that can read RAW format, but a simple CHKDSK from a direct MB based SATA seems to get right to the heart of the problem and takes care of the issue.

I am starting to get similar problems with the new drive that is plugged into this PCI SATA card. I think I will be updating that card or just removing it altogether and toss in a new MB with board based SATA connectors.

I have noticed this to be a common issue in recent months while searching the web for a solution. I hope that what I have found here can help others out. You don't need to go the route of data recovering software...you just need a second machine...:)

Thanks,
Chris
