 Posted: Mon Mar 20, 2006 1:44 am Post subject: DATA RECOVERY, NTFS using linux. |
 |
|
Hello all, I am a gentoo user. I have long since dumped windows, but a friend of mine is frantic and wants me to save his USB maxtor data drive's data (200gb of data!)
I took the USB enclosure apart, and I installed the drive on an IDE channel. The drive can bee seen in the bios, and dmesg shows it.
I have the NTFS modules compiled in my kernel, so it should try to load them when I try to mount, but when I try to mount I get this error:
| Code: |
mount -o ro -t ntfs /dev/hdh1 /mnt/floppy/
mount: wrong fs type, bad option, bad superblock on /dev/hdh1,
or too many mounted file systems
|
Here is a sfdisk of the disk:
| Code: |
sfdisk -l /dev/hdh
Disk /dev/hdh: 24792 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
Device Boot Start End #cyls #blocks Id System
/dev/hdh1 0+ 24791 24792- 199141708+ 7 HPFS/NTFS
end: (c,h,s) expected (1023,254,63) found (215,254,63)
/dev/hdh2 0 - 0 0 0 Empty
/dev/hdh3 0 - 0 0 0 Empty
/dev/hdh4 0 - 0 0 0 Empty
|
I fear that maybe the drive is dead, or the partition table is damaged. I dont want to bother with ntfs recovery CDs, since I dont have a CDROM installed. I wonder if there is any steps I can take just with gentoo? Thanks for your help!! |

| You might have more luck with a usb enclosure. |

| Code: |
ddrescue /dev/hdh1 /mnt/backup/ntfsimage
|
talked to some of the folks in #gentoo. I will try and do ddimage copy. If this works, I will be happy. If not, I will use one of the ntfs recovery tool cds. I think what may have happened to this drive was something messed up the partition table (a windows virus?)
So I will make a raw data backup using ddrescue first, ddrescues has been running with no errors! So I hope the disk is fine. If the data is then still unmountable. I will use some ntfs rescue disk.
Which should I use? salvagentfs? systemcdrescue? |
