Have been having problems with my hard disk. It finally stopped booting. i got another one, installed it and installed the old one, a Maxtor DiamondMax Plus8, as slave.

Ran >
[root@LaGrandota frazelle09]# fdisk -l

Disk /dev/hdb: 8455 MB, 8455200768 bytes
255 heads, 63 sectors/track, 1027 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda5 1276 9730 67909275 83 Linux

The first disk is the injured one. It is obviously not detected correctly. It is only 40 GB in size (C/H/S = 4998, 255, 63). MCC (The "Control Panel from PCLinuxOS, Hardware tab, reports two disks, hda and hdb.) Hdb correctly reports two partitions as hdb1 and hdb2.

There is another tab in Control Panel called Run Config Tool. This runs something which looks like GParted and which would allow me to mess with the partitions. i say "mess" because at this point when i select hdb1 it has a tab to select Mount point. i chose /boot because it didn't offer "/" and when i did so, it listed a number of files which i remember being on this partition -- mainly the OS, /home is on the other, hdb2, partition.

First question: Should i "keep" Mount Point /boot, or use "/" or does it make any difference? i don't care about booting this thing again, just want to get my files from the second partition.

Second question: The other tabs are: Resize, Format, Delete. If i choose Format, it asks for a file type. i was using reiserFS but it is not detected as such. It shous up as Ext2. If if i format this partition, will this wipe all the info?

Thanks for any help and have a great evening! smile.gif

Reformatting the partition will wipe out the information.

Yes it makes a difference and you do not want to mount your old drive to either / or /boot. I assume you are booting from sda which appears to have
a running linux OS.

Just create a directory to use as a mount point. You do not mention the distribution you are running but typically it will be /media or /mnt to use for
removable media or non OS data.

mkdir /media/olddrive

mount -t reiserfs /dev/hdb2 /media/olddrive

The partition table appears to be corrupted so trying to mount the partitions might fail.
