I am looking for a HDD dock that allows me to hot swap hard drives. Furthermore, I also want this device to allow me to store data on a hard drive then be able to retrieve Data from with in a tower. I say this because because i bought an external enclosure that would not let me do that. the hard drive was useless out side the enclosure and vice versa, I could not put a drive formatted outside of the HDD enclosure without formatting it inside the enclosure. I was look at BlacX Duet or BlacX 5G Snow Edition. would this give me a what I want.
