Hi - Thought I'd share what I found to switch hard drives. VM's are nice but sometimes loading onto a HD makes it easy to access hardware. I have a 6 BAY HDD Hard Drive Power Switch (Drive Switch)Power Controller -Orico HD-PW6101. Total of about 14 Gig of combined drive space and I can selectively boot, share or isolate drives with a push of a button. Drive-Switch-Controller-Orico-HD Tried a four drive switch but, the first one they sent was the wrong unit. They replaced it with a switch that was defective and then blamed me that I didn't know how to use it. Then had to argue with them for a refund... But, it was a nice unit. cooldrives Happy New Year!
