Re: USB drive is a CDROM drive and is not writable
This sounds like a "Smart" drive - can you confirm? I plugged it into a Windows system and it also recognized a CD drive. In addition, it vomited out a few popup windows and started something in the system tray. This is so ingenious that I think it must be a 'smart' drive. An article from the following URL tells me it is a 'U3 smart drive': http://www.everythingusb.com/u3.html I didn't know such a thing existed before today. I have one of these devices myself and simply removed the Smart partition to reclaim the space it takes up. Apparently there is a U3 uninstaller: http://www.u3.com/uninstall/default.aspx Thanks for the responses everyone.

Creating a cd9660 fs is normally a one hit prossess in which the fs is created fully populated and can't then normally be changed except on RW media by overwriting the entire fs. I don't know the device you are using but would expect that you can write a populated cd9660 file system directly using cdrecord (or perhaps burncd) without attempting to mount; just as you would on a conventional ATAPI or SCSII CD drive.

You won't be able to write to the CD partition of this flash drive. Smart isn't supported under *nix so the functionality it provides isn't available to FreeBSD users. I have one of these devices myself and simply removed the Smart partition to reclaim the space it takes up. -- Kelvin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I bet if you were to examine /dev/da0 you'd see the real writable FAT filesystem there. I wonder if it is doing fat->cd9660 filesystem emulation on the fly? -- Dan Nelson [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
