This system that I'm on...reflects such controller...because I'm using an additional PCI card to allow me to connect additional drives. In my case, the system itself does not provide RAID capability, but PCI card does. In your case, it's possibly built into the system but the function itself may not apply unless the user/owner employs a RAID.
As to the item you specified...Google draws a blank: Your search - ATVFSNSLF - did not match any documents.
I would recheck that.http://support.dell.com/support/edocs/syst...om/D5181bk5.pdf
So...you listed a reference in Device Manager that cannot be traced...and the laptop in question makes no mention at all of RAID or SATA capability. SATA drives are viewed in some BIOSes as SCSI.
I think you have a mystery, maybe someone else can shed some light on this.
Edit: Well...it seems that VOB Instant Drive...is not really a controller for hardware, but a controller for a virtual drive.http://www.pcreview.co.uk/startup/InstantDrive.exe.php
If you have a similar program installed on your wife's system...that might explain the DM reference. That's just a guess.
