I'm trying to mount my host's DVD-ROM drive to a VM.  I can view the contents of the disc, but if I try to copy a file from the disc to my VM, I get the error "Invalid MS-DOS function."  I have /dev/scd1 mounted and connected.  Is there some other component to this?

vSphere 4.1U1

I put the disc in the host DVD-ROM, edited the VM's properties, choes CD/DVD and checked "connected" and "connect at power on" then host device /dev/scd1

check the media is not bad.

try creating and ISO using ISO Recorder, to check the media.

The disc seems OK - I created an ISO with MagicISO and mounting it that way works fine.  I suppose it could be the drive, hard to tell with the host in production.  I take it no one else has seen this before?

"Invalid MS-DOS function." - I've seen this with disk faults, or bad formats.

I have to assume there is a hardware issue in this host.  Creating/mounting ISO from a local datastore works without issue.

Some files can be successfully copied off the disc, but others cannot, so I'm pretty confident the mount is right.
