I use win xp home. I have converted some harddrives to external storage drives using mail order enclosures on usb. My question is what kind of software should I put on these drives? I took my xp cd, used it to format the drive in NTFS then stopped short of fully installing xp. My computer recognized the drive as external mass storage and I was able to copy some test files to the drive. Any recommendations or is there any freeware I could use? Thanks.
