I was going to laugh this off 'cuz how many manufacturers support
Linux, but I was pleasantly surprised, twice, when I found that a)
Seagate does and b) the seatools for Linux produced no errors on the
long test.

It also told me lots of interesting information that I don't recall at
the moment, not the least of which was that the drive does not support
DST (the on-board diagnostics test), which I thought was odd.

Based on some of the other responses, I think I'll run smartctl to see
what it says, but that still doesn't really answer the question about
the number (4294967295 which happens to be FFFFFFFF).  There are only
a little over 5 billion sectors on the disk in total - how could 4.3
billion of them be bad?

I'm thinking it's more likely a 32-bit v. 64-bit issue, but I haven't
finished looking at that yet.

One other thing that I find interesting: the drives that are showing
smart errors are /dev/hdb and /dev/sda.  In order from oldest to
newest, my drives are:

/dev/hdb - Maxtor 120GB PATA
/dev/hda - Maxtor 160GB PATA
/dev/sda - Seagate 300GB SATA
/dev/sdb - WD 320GB SATA

The older of each of the PATA and SATA drives are the ones showing the
errors....

Thanks.
