Instead of having to include a CD with each device, they simply include it in the formware image. However, there is a convenience factor for users and you'll never lose the driver CD, which often includes a PDF manual too, unless you lose the device... and then it becomes unnecessary. -- Neil Bothwick Vital papers will demonstrate their vitality by moving to where you can't find them. signature.asc Description: PGP signature

Well, if I got an answer, maybe I wasn't asking the wrong person, as the OP didn't reply when I first asked it :) Personally, I wouldn't risk bricking £70+ of hardware when a one line config file entry would also get rid of the device. And that's assuming a suitably hacked firmware could be found in the first place, and that this part of the drive's behaviour was controlled by the flashable portion of the firmware.

when i connect the disc, the system sees two devices: a hard disc (for

manipulate.
If this works like the virtual CDROMS in 3G modems, you can get rid of it
with a udev rule that ejects the device as soon as it is detected.

thanks for your answer, but i take it that this only hides the
partition? any ideas how i can effectively delete it?

A quick googling basically said that people who don't like it sold it and bought a different brand... I think Neil's on the right track, you can make a udev rule to hide/disable/eject to it... I do not remember if udev has a blacklist functionality or not. maybe?

You can't if it is in the drive's firmware. It's not a physical partition
if repartitioning the drive doesn't touch it. ejecting the CD means it
is no longer present, that's why the device disappears.

Re: [gentoo-user] deleting virtual cd in usb hard disc
I had this problem with a SanDisk usb drive. Its been years since I did this but If my memory serves me correct I had to go to the SanDisk website and download a program for windows to remove the problem. I don't know if there is a linux alternative to something like this but I know how annoying it can be. I know there not the same brand but have you tried there website for something like this. I would think they would provide an option to remove the annoyance. Of course google might help as well.
