how to mount damaged hard disk?

windstory · 02-02-2009, 06:36 PM

I have a disk installed centos 5.2 x86 as guest and running under virtualbox at windows 7 as host.

Yesterday I removed centos disk and reinstalled windows 7, and re-insert centos disk, and failed to boot.

I checked centos disk with partition magic as shown screen shot.

However I could not mount this driver as follows;

Quote:

[root@localhost ~]# fdisk -l
Disk /dev/hda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 1044 8281507+ 8e Linux LVM

Disk /dev/hdd: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hdd1 * 1 77825 625129281 7 HPFS/NTFS
[root@localhost ~]# mkdir /odisk
[root@localhost ~]# mount -t ext3 -o rw /dev/hdd /odisk
mount: wrong fs type, bad option, bad superblock on /dev/hdd,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Please let me have any help to solve this problem.

You are trying to mount an NTFS partition as EXT3.

Here is a tutorial how to mount NTFS

sycamorex,

As you can see at the above-mentioned http://www.postimage.org/Pq16ZVvr.jpg, it's not NTFS.

Sorry, windstory, but either me and my web browsers are going loopy, or you have uploaded a poor quality picture (240x196) Besides, the option to zoom in is actually part of the picture

Please confirm if it's me who's going mad

you clearley show /dev/hda1 and2 being your linux partition's yet you try to mount your ntfs as ext3 + /dev/hdd woudent work eneyway it would be /dev/hdd1

SO lets start over just what did you do and what are you trying to do?

windstory · 02-02-2009, 09:45 PM

yes ok so I can see that partition magick sees your drives as disk3 NTFS about 3/4full set activ(boot)----------and disk4 having 3 partitions 2 ext3 and 1 8E-------the first ext3 being about 100Mb's and set active(boot)-----the second ext3 about 80Gig and not seen by fdisk for some reson?----the therd 8E----or the LVM?? but all 3 slap full?? --- but that dosent mean eney thing when it comes to trying to mount the drives the way you were trying to using the output frome fdisk!!!!partition magick dosent give a /dev/ location!

it looks to me like your linux partitions have ben mesed up and set rong I'm shure the small 100Mb partition should have ben swap and tharfor not set boot and the drives shouldent be slap full + fdisk isent even seeing 1 of them!! try examining the drives with a gparted livecd and see if it sees the drives right. or see if you can acses your data on them with some livecd to save what you can and then redo them frome scratch

windstory · 02-03-2009, 01:59 AM

vinnywrite,

Thnaks for your kind suggestion.
I will try gparted of livecd and post her the result.
