That's what my thoughts were also. I can see it being used to try and remove a virus without having to worry if the drive itself got infected but beyond that I'm not seeing how read only prohibits the virus on the drive infecting the computer it's plugged into. I could see this possibly being used in a corporate environment where you don't want people deleting or modifying the files but even that is a stretch. Who cares if Forensic investigators can quickly discover if the interface bridge was tampered with and replaced with a read/write enabled board, the drives are removable so what impact does that even have? The only way I could see this working is if the unit itself encrypts all of the data so you could remove the drive, but couldn't use it on any other computer.Ok....so you buy this thing and connect it to your puter say to store backups..... how you get data on it ? How does it protect your computer if your computer can read any infected drive you put in it ?
