My system: XP Home w/service pack 2 1gig ram DFI Infinity II motherboard with USB 2.0 I got a good deal on a brand new Seagate 160gig harddrive ($25) and attached it to my computer as a USB mass storage device using a USB to ATA (PCI?) adapter which has its own power supply connection. 2 Questions: (1) When I try to format the drive with the administrative tools it goes thru the whole format process and then at the end I get the message "Windows is unable to format" or something similar. The drive shows up as healthy with a 149gig partition in admin tools, and when I click on the drive icon in "My computer" I get the message that the drive is unformatted and asks to format. Seems this should work. Maybe missing some key update or software. I scoured the internet for solutions but have been unable to find any. (2) Right now the drive is just sitting on my desk next to the monitor. Do I need any heat disipation or dust containment? Thanks in advance for any help.
