Yesterday, I tried to use the machine only to have it report errors on all disk read attempts. I rebooted and the BIOS didn't recognize any of my tree SATA drives. I left it off for a few hours as we had a party to return to. I powered on afterwords and it worked fine. I blamed it on heat.
The next morning, it was still on. I tried to use it and immediately got disk read fails. I again rebooted and again none of the drives were recognized. This is a bit odd as two drives are attached to the motherboard and another to a separate card. I fiddled with cables and got it to boot long enough for it to try an automatic
fsck but not long enough to finish. Then I realized that all three drives were connected on the same power line. (I have a newer power supply with power cables that plug in at both ends.) Fiddling with cables seemed to get it to stop failing to recognize the drives. I booted on my Knoppix disk. Three partitions seemed fine. One, it couldn't recognize. My home directory.
This caused some consternation as just yesterday I'd noticed that one important directory wasn't being backed up: the directory that contained about 500 scanned family photos, including all the wedding pictures.
Booting without Knoppix eventually got me a single-user root prompt. Running
fsck reported a couple nasty errors, but now the machine seems to boot correctly. I wonder what I should do...
(Besides making backups, that is.)
