I plan to use one eSATA 4tb dual external hard drive (G-RAID) between two computers, both win 7, 64bit home premium os’s as stand alone units. I will move the external drive between the two computers to use as backup and video work, I would like both computers to see the same drive letter (K as an example every time the drive is reconnected to either computer. However, at the moment I have no idea how to set this up yet. Any information would be appreciate.
