Hi, I have a Dell D600, and I count mount flash devices on it. They show up in dmesg. Here I put the drive in the top one, pull it out and stick it in the bottom one, and then put it back in the top one: ugen0: SanDisk Corporation Cruzer Mini, rev 2.00/0.10, addr 2 ugen0: at uhub0 port 1 (addr 2) disconnected ugen0: detached ugen0: SanDisk Corporation Cruzer Mini, rev 2.00/0.10, addr 2 ugen0: at uhub0 port 1 (addr 2) disconnected ugen0: detached ugen0: SanDisk Corporation Cruzer Mini, rev 2.00/0.10, addr 2 Strangely, they show up as the same address on the same device. When I try to mount ugen0, I get a message that sayeth: Block device required. What does this mean? What do I do? - Jason Saint Aardvark the Carpeted wrote: > Jason Dusek disturbed my sleep to write: > >>In that there must be something else wrong, because after trying a few >>permutations I was unable to get the drive on my D600 to work: >> >> 1 root # mount_cd9660 /dev/acd0 /cdrom >> mount_cd9660: /dev/acd0: Input/output error >> >> 2 root # mount_cd9660 /dev/acd0c /cdrom >> mount_cd9660: /dev/acd0c: No such file or directory > > > Huh...you should have /dev/acd0c already.
