Even though you may have a newer PC i believe these exceptions are still written into modern day CMOS info...
Please try any other drive letter other than A or B...and see what happens.
My understanding is as long as the drive letter is available you can use it. Iíve never seen where it states you canít use either of those letters, especially in Vista/Windows 7.
Anyway you can actually assign "B" to a drive if you want as long as it's not used elsewhere. I've done it myself in the past, even with XP. Haven't tried "A" but that's also assignable, again, as long as it's available - Can I use the B: drive on my PC? - B drive PC | Ask MetaFilter
Now, Windows may have it's "default" drive letter assignment, but you can change those around. The only one I'm not sure about is "C" drive. Can you for example make C "D"? That I haven't tried.
