my problem is that my computers data drive is showing as raw i did some research last night and all i could come up with is to try and retrieve the data then reformat i was wanting to se f there might be a better solution to fix the issue as to why this happened i could not tell you all i do now is that i noticed the issue after a install of debian on a bother drive that also has windows for a dual boot

A volume (or partition) seen as RAW may mean several things:
  • the partition or volume is OK, BUT the pointers to it in the MBR or EBPR are "wrong"
  • the partition or volume is OK, BUT the pointers to it's filesytem structure in the PBR/VPR are "wrong"
  • the partitition or volume is actually (partially or totally) corrupted

If #1 or #2 it is generally trivial to recover and there is no need whatsoever to re-format.
If #3 in some cases, once recovered the volume a CHKDSK is enough, but if the partition/volume cannot be recovered, and you get (hopefully) the data back with file-based approach then you need to re-format.

First thing you should check if any of #1 or #2 is true, then attempt recovering the partition and only if this is not possible go ahead with file-based recovery attempts.


Preliminary questions:
  • Which OS are you currenty running (or which Os can you use to access that disk/partition)?
  • Are you familiar with command line?
  • Are you familiar with a disk editor ?
  • Have you available another disk to copy the thingy (possibly the WHOLE disk, but also the partition might do, once verified it is NOT #1 may be enough) to (dd-like copy)?

Also try to recover the PBR with Testdisk.
It helps in some cases which windows won't be able

Just for the record the "Also" is EXACTLY #2. :whistling:

Running *any* recovery tool, expecially if you are not familiar with it and until you haven't a "forensic sound" copy of the disk, is IMNSHO "playing with odds".

1 windows 7, Debian neither can access the disk windows just wants to reformat it but it does show up as a disk with both
2 a little i know enough to know when to stop before i get into trouble
3 gparted or acorns are the two i know about off hand
4 no i would need to use more then 1 HDD to back up the disk as i do not have one that is big enough to just copy the whole partition

The lack of capacity for making an integral copy is a problem.
You have to be particularly careful.
Ideally, if you have another system, it would be easier to connect the hard disk to this "other" system, as to have a "full" OS working as opposed to a Live CD.
You can use dd (or a similar program) to backup "chunks" of the hard disk, something similar to what was explained here (though the issue was the unreadability status of the disk, something that you should NOT suffer by):
http://reboot.pro/15040/
that app automatically names the chunks with start address/length, you can do the same with dd or similar, but as said you have to be careful.

The suggested LiveCD is parted magic, as it contains by default testdisk.

Even before doing the imagiing, if you promise you won't write anything you can have a quick look at the partition with testdisk, maybe it is one of those "easy to solve" issues.

Remember that drive was partitioned under Windows 7 (I presume) so you have to go to advanced and set to not respect Cylinder boundaries.
Run testdisk with a log and post the log (or upload it somewhere and post a link to the file).
Follow what has been done in this thread:
http://www.msfn.org/...ith-value-data/

Before anything make sure you have read and got familiar with these:
http://www.cgsecurit...sk_Step_By_Step
http://www.cgsecurit...sector_recovery

If you have any doubt, ask before doing something you may later regret.

Alternatively, you can try PartitionGuru or Paragon Hard Disk Manager to easily and safely recover a lost partition in 1-2 clicks, if you prefer EasyButton®. :)

Well, you will need to fill some gaps.
The log shows three disks:

Hard disk list
Disk /dev/sda - 500 GB / 465 GiB - CHS 60801 255 63, sector size=512 - Hitachi HTS725050A9A364, S/N:091104PCE400VLG29AGC, FW:PC4O
Disk /dev/sdb - 640 GB / 596 GiB - CHS 77825 255 63, sector size=512 - TOSHIBA MK6465GSX, S/N:Y0J8S1LHS, FW:GJ00
Disk /dev/sdd - 1031 MB / 984 MiB - CHS 125 255 63, sector size=512 - Memorex TD Classic 003C, FW:5.00

The issue should be the TOSHIBA one:

Invalid NTFS or EXFAT boot
1 P HPFS - NTFS 0 1 1 77824 254 63 1250258562
1 P HPFS - NTFS 0 1 1 77824 254 63 1250258562

Ask the user for vista mode
search_vista_part: 1
search_part()
Disk /dev/sdb - 640 GB / 596 GiB - CHS 77825 255 63


TESTDISK can find two Linux partitions and a number of floppy disk images, but it has found this:
1 P HPFS - NTFS 0 1 1 77824 254 63 1250258562
which does look as a primary partition, NTFS, on a disk partitioned with 2k/XP (old cylinder boundary scheme) with size:
1,250,258,562*512=640,132,383,744 bytes
Since the Toshiba disk is 77825*255*63=1,250,258,625*512=640,132,416,000 it should mean that the disk was previously partiioned in a single huge 640 Gb NTFS partition.
Can you confirm this?

If yes, you can try doing what is explained here:
http://www.cgsecurit..._for_partitions
highlight that partition and press p to see if the files are there.

then do like here and ONLY verify that the backup bootsector is OK:
http://www.cgsecurit...sector_recovery

It woud be a very good idea to backup:
  • current MBR/partition table (even if invalid)
  • current PBR/bootsector of that partition (even if invalid)
before attempting writing anything to disk.

From a Linux you could dd the first 100 sectors of the disk to a file (on another disk), or do the same from Windows 7 (though windows 7 has some problems with letting programs access the MBR, so if using the latter you should put the disk offline first):
http://reboot.pro/8200/page__st__39
(it depends on the tool you have handy, some may work allright, as they do the same automatically)

ok the way i have my computer set up is like this the Hitachi drive is the main drive that has windows and Debian on it in a dual boot setup, the TOSHIBA witch is the drive i have the issue with is what you would cal a data drive witch has all my personal data on it the Memorex was a flash drive that had test disk on and yes the drive was one big partition

... and yes the drive was one big partition

good, then you can proceed with the given steps. :)

Once you have the backup of the mentioned bunch of sectors (just in case), IF when pressing p you can see your files, THEN you can go on and try fixing the bootsector by using the backup one (IF TESTDISK says that the backup one is OK)

I have just read all through this post and was thinking how patient Wonka the sane was and how good the explanations were. Then I get the end and there is no outcome, no thanks very much not even that trashed my disk and lost everything.
I don't normaly comment but that just annoyed me
