I've got an external hard drive connected via USB (Seagate brand). For a couple of years, every time I turned the machine on, when I looked at "My Computer" the Hard Disk Drives were Local Disk (C:) and Sea Disk (E:). Devices with Removable Storage were 3 1/2 Floppy (A:) and DVD-RAM Drive (D:). Then one day, the Sea Disk suddenly changed itself to F, and then within a couple of days to G (now I've got no E or F drives). Didn't cause me a lot of problems, because I'm reasonably savvy at using computers, but I'm just wondering, what caused this assignment change? At the time, I did have a HP printer with some memory card slots that had always been F. I can't remember what they changed to. There was a few ink problems with the printer after I'd had it for a couple of years, and I replaced it a few weeks ago. The new one doesn't have the memory card slots, so has no drive letter assigned to it.

Most likely the printer did cause your external drive letter assignment to move. Assuming you are using Windows XP, here is how to fix it.

First, plug in your external drive and get it running.

Right-click on My Computer
Select Manage
Select Disk Management under the Storage section
Right-click on your external drive (G: )
Select Change Drive Letter and Paths
Select Change
Pick the new drive letter

You should be in business now.

Hope this helps,

Thanks, I knew how to change it back, but don't think I'll bother. Yes it's XP. I thought it had something to do with the printer. It started doing some funny things. Cheers.
