My hard drive got some bad sectors several days ago and my partition table was lost in the meantime. But I got some information from Linux RAID log.
I wonder whether I can reconstruct the partition table from it.

Here are some details of my system.

Two harddrives are Samsung SP1404N.
hda is the first drive and the hdc is the second drive

Soft raid level 0:
md0 : hda2 + hdc1
md1 : hda3 + hdc2

Partition table:
hdc: LOST
start end blocks ID System
hdc1: 1 83 Linux
hdc2: 3649 83 Linux
hdc3: 3650 19457 126977760 f W95 Ext'd
hda:
Disk /dev/hda: 160.0 GB 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units: cylinders of 16065 * 512 = 8225380 bytes
start end blocks Id System
hda1: 1 9 72261 83 Linux
hda2: 10 1833 14651280 fd raid auto
hda3: 1834 3657 144651280 fd raid auto
hda4: 3658 19457 126913500 f W95 Ext'd
......

some RAID log:

If you can manage to partition around the bad sectors and blocks, once you do this, you can make an exact copy of the partitions to the other drive or drives by doing a:

/sbin/sfdisk /dev/hdX -f /dev/hdX

Where X is your drive, etc..

Your probably better off replacing the drive though, less hassle in the long run..
