I saw a mail yesterday about something nearly like this, from nej, except with him, the umass device wasn't reporting anything at all, no device when he plugged it in. I sent him a little piece of usb driver code that resets his usb buss, just to experiment and see if that got his devices correctly detected, but he didn't yet reply, I don't know if it worked for him. I don't have something like that to experiment with. With yours, you obviously have a da2 ... that only means you have a direct-access disk devide #2 being detected. The next step is to figure oout what kind of formatting you have. Hopefully, it's been fdisk'ed to where it has partitions, so do this (as root): "/sbin/fdisk /dev/da2", and in fdisk, give the 'p' command, this will print out the formatting for any partitions. Likely it's either one of the various Microsoft things, or a Linux one, or even a FreeBSD one. Depending on what you see, you either directly give a mount command next, to the right partition, or maybe you use bsdlable to find out what the disk-labelling is (if it's a FreeBSD disk). Probably the right thing to do is to reply here with the results of the fdisk, then whoever jumps on it first can give you the right thing to do next. I'm not going to try to tell you all the possible ways to go at this point, not without that. > # > > (The disk is from another FreeBSD system so is UFS2 and da2s1f is /usr > on the other system) > > So although it mounts, nothing is visible. > > After a few minutes this happens: > > umass0: at uhub3 port 1 (addr 2) disconnected > (da2:umass-sim0:0:0:0): lost device > (da2:dead_sim0:0:0:0): Synchronize cache failed, status == 0x8, scsi > status == 0x0 > (da2:dead_sim0:0:0:0): removing device entry > umass0: detached > > Tried it under 7.0-RELEASE and it's even worse - it crashes the kernel with > > Fatal Trap 12: page fault in kernel mode.
