I have had one 80 gig external for a while; photos, itunes etc. (H drive)
The new 250 gig is strickly for backing up business files. ("I" drive) Somehow when I set that one up it took the letter of my other 80 hard drive. Now when I try to access the old H drive it sees the old file names but the file is not there. Naturally I have thousands of songs that I can't access. Can this be fixed?
Thanks
