Disclaimer: I am extremely computer illiterate so please bare with me My work computer (which I am on now) is on a network. Recently I had to assign a drive to a USB connection which I did fine with instructions I found on the net (see below) How to assign a drive letter To assign a drive letter to a drive, a partition, or a volume, follow these steps: 1. Log on as Administrator or as a member of the Administrators group. 2. Click Start, click Control Panel, and then click Performance and Maintenance. Note If you do not see Performance and Maintenance, go to step 3. Performance and Maintenance appears in Control Panel only if you use Category view. If you use Classic view, Performance and Maintenance does not appear. 3. Click Administrative Tools, double-click Computer Management, and then click Disk Management in the left pane. 4. Right-click the drive, the partition, the logical drive, or the volume that you want to assign a drive letter to, and then click Change Drive Letter and Paths. 5. Click Add. 6. Click Assign the following drive letter if it is not already selected, and then either accept the default drive letter or click the drive letter that you want to use. 7. Click OK. The drive letter is assigned to the drive, to the partition, or to the volume that you specified, and then that drive letter appears in the appropriate drive, partition, or volume in the Disk Management tool. when I got to step 4/5/6 above, there was alist full of the drives from A through to Z and I could choose which letter drive I wanted to assign to this USB connection. Today I have tried doing it again with another USB connection, only to find that the only letter that comes up at steps 4/5/6 is C (being C drive??). Does anyone know where I have gone wrong?! Your help is muchly appreciated!!
