Norton has pretty much quit pushing Norton Tools, since many of the old ones duplicate utilities built into WinXP so there's not as much market for them, and several of the old ones simply don't work all that well with newer Win versions (even with Win2K and WinME).

If you can install a partition, you should be able to defrag it with the built in Windows defrag. The only question really is whether you'll be around long enough to see it finish. With Win98SE, I think my record longest was about 18 hours for a defrag on a 2GB partition. It doesn't usually take that long, but especially a "first time" cleanup may look like it's not doing anything for a very long time.

Note that for your large drive (160GB) you should NEVER attempt to do a "Low Level Format." Consult any hard drive mfr's website for info on this. You almost never can recover the full capacity of any recently made HD (any over about 8GB) once you've attempted a low level (FDISK FORMAT). You can use FDISK to set partitions, and then exit FDISK and use the FORMAT command to format each partition; but again, I'd recommend getting an HD maker's setup and diagnostics program, or perhaps use a recent Partition Magic.

If you look in hardware manager (Device Manager? I forget which Win98 calls it), it may tell you a mfr's name, from the PnP ID it read from the drive, although often it's just by a generic drive type.
