What about this partition table? Since when can't you mount it?

partition table should be OK. If using 2.4 kernel, disk can be identified and can be mount at /dev/hda1 and /dev/hda2. Two partitions exist on disk and both of them are ext3. I tried to run mkfs on /dev/sda1 and /dev/sda2 within 2.6.19 kerenl, also failed. The nodes for sda1 and sda2 exist at /dev/ folder with major is 8.

Any suggestions? Thanks.
