I run WinXP on a pc with 2 hard drives, and an external hard drive for back-ups. It was working perfectly. Recently I had the 10Gb C: drive replaced with an 80Gb one. When I formatted and re-installed XP the Drive letters were haywire - C: had become H:. My supplier came and unplugged the second hard drive and I re-installed XP which then showed correctly as C: He then revisited and reconnected the second hard drive but it did not show in My Computer, though he said the computer recognised a second volume. After he'd retreated, saying he was baffled, I just thought I'd restart again and, to my delighted surprise, the two drives both then showed up in 'My Computer' BUT now, in Computer Management, D: is called a USB Removable Storage Drive and the external drive has no drive letter, and is viewed as a Logical Drive. If I double-click on it the menu is greyed-out except for 'Delete Partition'. If I click that it warns that deleting the partition will lose all data which I certainly don't want to do, although I can't now access it. If I disconnect the external drive the D: drive disappears from My Computer.. How can I get the computer to label the drives correctly and make all 3 accessible? Thanks for reading this and for any help.
