L 80 80 ... How to rewrite MBR?

manudath · 02-27-2005, 09:27 AM

Hi,

I have a Debian server with RAID-5 running on 3 SCSI drives...

One of my drives have gone bad... and when I try to boot from the 2nd drive, I get this error while booting:

"L 80 80 80 80...."

Someone suggested that the MBR might have got corrupted and I am trying to get my original MBR so that I could boot the system....

Anyone has any ideas regarding this?

Thanks,
Manudath

your second drive does not have a boot record. If you look, you will often find the first block of a drive that has no MBR is filled with 0x80 for the first 443 bytes, and the partition table after that.

You need to install a bootloader on the drive.
