I have Windows XP, NTFS. I just recently purchased another ext hd. I already have 3 Maxtor One Touch II's ext hd's that are firewired. I also have 3 Seagates and 1 Hammer that are connected using USB 2.0 cables. The new drive is a Western Digital. I disconnected all of my other ex hd's that were connected using USB 2.0 cables and connected the new one to each of those ports with the cable and power supply that came with it. Each time, it's spins up but the drive isn't recognized in My Computer nor does it appear in Disk Management. I also tried connecting it by Control Panel > Add/Remove Hardware but the wizard can't find the new hardware.
Do you think it's a defective drive or is my pc not recognizing it because it's connected to a port that's been reserved for a different ext hd?
