Solved - XP won't assign a drive letter Hi, I just put together a new P4 system runnning Windows XP and tried to add my old HD (Maxtor 80GB) to it. It is jumpered properly as a slave and is recognized by the BIOS. It does not appear in My Computer, however, it is listed in Device Manager. I've tried removing it from Device Manager and reinstalling it with no success. Under Disk Management, it is displayed as Disk 1 and has a Healthy, Active Partition but just a blank space under Volume. I can't assign it a letter because the 'Change Drive Letter and Paths" option is grayed out when I Right Click on it. Does anyone have any ideas? I played around with Microsoft's diskpart.exe to try and manually do it, but I don't know how to use it very well and the command line interface isn't very helpful. Thanks for any advice!
