Thanks Michel,

That helps, but I'm still not sure I'm looking in the right area.

Here's my problem:

I'm changing the write protect state on a USB flash drive, using vendor unique SCSI commands. In order to do so safely, I'm looking at 3 (or four) steps.

1) Unmount the drive's volumes (Hopefully this will be adequate to insure that all caches are flushed).

2) Change the drive's write protect state (vendor unique SCSI command).

3) Remount the drive's volumes.

It's possible that I'll also need an additional step.

2b) Somehow, magically, convince the drive's device driver that it needs to reestablish its write protect state.

Now for the hard part:

All of this has to work on Windows XP, Windows NT and Windows 7. Support for Windows Server flavors is optional.

Ideally, this has to work on a user account, without administrator privileges.

I guess my first task is to determine whether or not this is even possible.

Thanks for your time,
