NTFS suddenly converted to RAW

Hello

My desktop is running on XP. When I tried to install HP printer, one of my secondary 80GIG NTFS file system changed to RAW. And I was not able to access this disk. Everytime I try to eplore, Windows prompting me to format disk. But I dont want to format disk.  I have stored lot of data in this drive. Is there any way to get the data?

File allocation table is corrupt. Try chkdisk, sometimes works, otherwise Getdataback from www.runtime.org is a great program. Some other opinions before doing anything radical of course. A Knoppix disk can be useful. If it can mount the drive, you should be able to recover data.

Knoppix is indeed "freeware" - see www.knoppix.org . It can read NTFS partitions, if I remember correctly, but I suppose the damage may have rendered the partition unreadable except if you use a data recovery program.

There have been a few threads here about NTFS drives/partitions acting up and becoming inaccessible and/or damaged without any apparent cause. Perhaps there is a bug...

is it issue with NTFS or XP ?

I can't say for sure. The threads I've been following suggest that it is the file system, as the problem is said to occur in both w2k and XP.

It is a filesystem isue, not XP specific, but as rid indicates, there appears to be no certain cause or fix at this point. Knoppix is linux on a cd. Boots from the cd. If it can read the disk, you will (from memory) need a fat or fat32 partition available for it to transfer the data to. It can read ntfs, but not write it. (I think). I once used it to recover data from half a mirrored SATA raid array. If it can do that it can do almost anything.

Good luck

Further to the knoppix suggestion...
I have had limited success recovering partitions using
linux fdisk, either by toggling the partition type or creating
a new partition over the existing RAW partition that has
exactly the same start and end positions, and is the same
filesystem type.

Alternatively, the trialware (but functional) program at
http://www.terabyteunlimited.com/bootitng.html has an
interestingly competent partition undelete function.
