Go into setup and ensure that:
1. The disk is not set to RAID.
2. The SATA is in "legacy" mode.
Depending on the computer, either of the above may or may not exist.
> I have a problem with one of our labs linux box. It is running Red Hat Enterprise Linux AS (2.6.9-rtl) It will not boot, asks for root password to enter repair mode. The error is as follows:
> > The superblock could not be read or does not describe a correct ext2 filesystem.If the device is valid and it really contains an ext2 filesystem then the superblock is corrupt and you might try running e2fsck with an alternate superblock. fdisk -l shows 4 dev. /dev/sdb1 through /dev/sdb4 with 1 being linux, 2 linux swap, 3 linux and 4 being linux raid autodetect. I ran fsck on all but swap and 1,2 were clean and 4 failed. With that failure, in addition to the superblock error I got a bad magic number in superblock while trying to open /dev/db4. I then ran mke2fs -n /dev/sdb4 to find where alternate superblocks were stored. I found them and have tried most of them with the same errors resulting. From what I can tell this box has two hdd's and is possibly a RAID0 box. I would appreciate any guidance or suggestions you may have as to how to proceed.
