I was wanting some more diskspace and I went to get a 2TB drive. 3 TBs were only $30 more. I figured what the heck. Big mistake and maybe I should have returned it. The computer it was to be used on is XP. I quickly surmised you need a 64 bit computer to access 3 TB. I have 2 Win7 computers but neither were working. A month or 2 later, I got one of the 2 up and running. I was shocked to see the drive was still 746 GB. Then I discovered the BIOS needed upgrading and that company went out of business long enough ago that I am not even going to look for it. I can ask a friend if I can use his computer to partition and format the disk. If I can partition into 2 x 1.5 TB drives and format them can I access the drives on a 32 bit OS? Thanks!
