Sometimes when you install new hardware or remore a hard drive, the drive letters can get out of sync. For example, if you added a new hard drive on a system with an existing hard disk ([B]C[/B]) and DVD drive ([B]D[/B]) then the new hard drive letter would be [B]E[/B]. If you wanted to change this letter to [B]D[/B] and make the DVD drive[B] E[/B] (swapping them) then you should follow the instructions in this guide. First, load the Computer Management tool by running [B]compmgmt.msc[/B] from the run menu (Press [B]WINDOWS KEY + R[/B] to load this): [CENTER][ATTACH]91.vB[/ATTACH][/CENTER] Then click on [B]Disk Management[/B] on the left hand menu to bring up a selection of your current drives: [CENTER][ATTACH]90.vB[/ATTACH][/CENTER] Right click on the drive that you wish to change the letter of, and select [B]Change Drive Letter and Paths[/B]: [CENTER][ATTACH]89.vB[/ATTACH][/CENTER] Click [B]Change[/B] on this screen to select a new drive letter: [CENTER][ATTACH]88.vB[/ATTACH][/CENTER] Now, choose a new drive letter for your device and click [B]OK[/B]: [CENTER][ATTACH]87.vB[/ATTACH][/CENTER] If you want to swap drive letters around, you'll have to rename one of the drives to a 3rd temporary letter to create space in the letter allocation.
