Thanks for sticking with me Dave. I tried fsck with vfat, msdos, ntfs,
reiser, ext 2 & 3 to no avail. I got the list of superblocks for block
sizes 1024, 2048 and 4096 but they didn't help either.

Thanks for the explanation of the partitions and volumes.
I tried changing the bios to boot from sdb but it complained that "NTLDR
is missing" and didn't get into grub.
The Error 16 happens once in 4 reboots. I haven't been able to see any
pattern.
I used mke2fs under verbose to put ext3 on sdb1. It went through the
badblocks tests without comment. I saved the screen output to sda1, the
ntfs drive, to have a record.
Since then I get the Error 16 every reboot but in 4 of 5 tries it booted
when I selected the current kernel. The other time I had to select the
current kernel twice.
Could the problem be I seem to be using the master boot record of sda
while booting on sdb? I thought we couldn't do that? My plan was to make
sdb the boot drive but the bios is currently set for sda. Now though it
seems like I would have to install a MBR on sdb?
Would the problems be solved if I put all partitions in fstab?
This computer is not faultless. My daughter used this computer for a few
years under XP but she had more and more problems. She became so
frustrated I bought her an iMac. Under Linux, at least this XP
computer's sound problem is less bothersome. But maybe the problem was
the computer rather than XP. I might end up buying a new computer or two
and keeping any salvageable parts.
Thanks for your help. This is quite a puzzle for someone of my
experience.
