Maybe something has kept the > block device open, but no other processes should be allowed to open it. there aren't any. i'm running fvwm, and commands are run explicity. i usually use curses-based tools, explicitly typed from the command line in an xterm. so there's no gnome or kde or any kind of file managers, file commanders, nothing. nothing that could be f******g around without my knowledge or permission, and that's the way i like it :) the only other thing is: there is actually a built-in CD/DVD drive, listed as /dev/cdrom1 (not /dev/cdrom), so the USB device came up as /dev/cdrom11 - all a bit weird, but hey. >> Apr 17 09:33:07 teenymac kernel: [1201988.327917] sr1: scsi3-mmc drive: >> 62x/24x writer dvd-ram cd/rw xa/form2 cdda tray >> Apr 17 09:33:07 teenymac kernel: [1201988.328255] sr 9:0:0:0: Attached scsi >> CD-ROM sr1 > > Drive reattached.
