You need an operating system that can accomodate a drive that large as
well as a BIOS that uses 48bit LBA. Assuming the BIOS is OK, W2K needs
at least SP3, and WinXP needs SP1.
If you would define "a system", it would help.
I suppose the distinction needs to be made as to what role this drive
plays. It might be additional storage supplement rather than a swap of
the primary OS drive.
The OS (WinXP SP1 or Win2K SP3) isn't a requirement when using an IDE
controller whose driver supports 48bit LBA. For example, I have a system
with a 160GB drive running on a Promise RAID controller (integrated but
equivalent of a Fasttrack TX2000) under Win98SE. Win98SE's scandisk can't
be used, generates "out of memory" error, and I disabled the DOS scandisk
(renamed the file) to eliminate possibility of it running in DOS after bad
shutdown in addition to disabling it in msdos.sys (AutoScan=0). The drive
is used as storage, not the boot/OS drive... haven't had a chance to test
different "large drive" configurations under Win9x yet. Disk scanning is
done with Norton's Disk Doctor... Might work with McAfee/Network
Associates or other popular disk scanners but I've not tried 'em.
