Yes, I mounted the drive into VM, but it was not the system drive. The drive in question was my old system drive before I changed my MainBoard. I used to have two IDE drives, but my new board only supports one IDE cable, with my DVD-RW I had to move one drive to a usb. At the same time as updating I also bought a SCSI to be used as the system drive. Anyway, that IDE drive was a spare. I have been using VM for a few years now and never had problems while mounting drives and sharing them between the host and client. But, I did recently upgrade to a newer version of VM, so that could very well be the problem. The drive seems to be working ok now, and while it is I'm going to sell it. I just got another SCSI, so really, it's of no use to me.
