I transferred all my music from my desktop to my SimpleTech external hard drive, so that I could reinstall my OS (Windows Vista Ultimate) I tried to put back on my computers Hard Drive, and when I copy the folder on my external and paste it to a older on my desktop, it tells me the file is no longer located on the drive. But then when open the External HD folder all my files are there, and I can even play them from the hard drive. Please help because it's not my external drive, it's my moms, and she said when she needs it shes deleting my music....I have about 25,000 songs, and I would really appreciate not losing them
