It sounds like the BIOS is set to check for drives on all the IDE interfaces every time it boots, and not all interfaces have drives on them. There is nothing wrong with this. I normally turn this off, and set the drive types in the BIOS, but I also know to go into the BIOS and change things if I change drives. One other thing to keep in mind is that we do not know if there are really 3 IDE drives. From what the OP has said, I am not sure how much he really knows about his hardware. It would be interesting to see the output of "fdisk -l" when run as root. This would tell us both how many driver there are, and what interfaces they are on.
OK, the result of 'fdisk -l' is: # /sbin/fdisk -l Disk /dev/hda: 120.0 GB, 120034123776 bytes 255 heads, 63 sectors/track, 14593 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 3187 25599546 c W95 FAT32 (LBA) /dev/hda2 3188 3200 104422+ 83 Linux /dev/hda3 3201 14593 91514272+ 8e Linux LVM Disk /dev/hdb: 81.9 GB, 81964302336 bytes 255 heads, 63 sectors/track, 9964 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hdb1 * 1 764 6136798+ 83 Linux /dev/hdb2 765 9964 73899000 5 Extended /dev/hdb5 765 904 1124518+ 82 Linux swap / Solaris /dev/hdb6 905 9964 72774418+ 83 Linux Disk /dev/hde: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hde1 * 1 10000 80324968+ 83 Linux /dev/hde2 10001 19457 75963352+ 8e Linux LVM Disk /dev/dm-0: 92.5 GB, 92576677888 bytes 255 heads, 63 sectors/track, 11255 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/dm-0 doesn't contain a valid partition table Disk /dev/dm-1: 1073 MB, 1073741824 bytes 255 heads, 63 sectors/track, 130 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk /dev/dm-1 doesn't contain a valid partition table Paul
