alright, I've finally gotten around to replacing the failed drive (I
know, I know, should've done this as soon as it failed, but I've been
so busy I hadn't had a chance until now). Anyway, the drive that
failed was a 160 gig Maxtor IDE, so I purchased another 160 gig Maxtor
drive to replace it, but I couldn't get the exact same drive, I
ordered the closest thing I could find. I was just trying to copy
over the partition table from the working drive (hda) to the new drive
(hdc) by using:
sudo sfdisk -d /dev/hda | sudo sfdisk /dev/hdc
and I get the following:
Checking that no-one is using this disk right now ...
Disk /dev/hdc: 19457 cylinders, 255 heads, 63 sectors/track
sfdisk: ERROR: sector 0 does not have an msdos signature
/dev/hdc: unrecognized partition table type
No partitions found
Warning: given size (317155167) exceeds max allowable size (312576642)
sfdisk: bad input
dmesg shows the following:
hda: 320173056 sectors (163928 MB) w/7936KiB Cache, CHS=19929/255/63, UDMA(100)
hdc: 312581808 sectors (160041 MB) w/8192KiB Cache, CHS=19457/255/63, UDMA(100)
so it seems the new drive (hdc) is slightly smaller than the current
working drive (hda).. Does anyone have any suggestions of what to do?
I guess I could manually create the partition table to be similar to
the current drive, then copy over the contents of the current drive to
the new drive, then copy the partition table from the new drive to the
current drive and then get them to resync.. But I'm wondering if maybe
there's an easier way. If anyone has any advice, please let me know..

I'd check the smartctl -a /dev/hdX output. But in any case, the
other two are right. Also see question 19:
