I've installed a Maxtor 200Gb disk in a casing and connected it to the puter with USB cable.
On a separate USB 2.0 card.
Partitioned it with Acronis PartitionExpert.
How or what do I use to format the USB dive?
Can I or can't I use one big partition with FAT32?
Win2k is the O/S & because win98 shall be able to communicate properly with the other OS's in the network
You will have to divide it into about 7 partitions to get them small enough for FAT32. Standard FAT32 has a limit of 32GB partition sizes.
Like said above, Win 98 can see NTFS files on a share drive. You are not networking the drive, you are networking the system. Confirm that to be sure.
NTFS can format up to a 2TB partition
EDIT - I failed to mention that 2TB is "in theory". The OS using it or other hardware issues may limit this as well. END EDIT
