Hi, I have an old home server which ran out of disk space so I added a big disk over USB which I use for backup (mounted on /backup). Problem is that it has happened a few times that the USB controller has crapped out resulting in the disk being dismounted and the backup filling out /. I then have to reboot to be able to access the disk again (fsck/mount).
Is this due to my ancient HW, crappy USB controller card, or is USB mounted disks just less stable? /jkm /var/log/messages: Dec 17 03:12:17 maya /bsd: ehci0: unrecoverable error, controller halted Dec 17 03:12:17 maya /bsd: ehci0: blocking intrs 0x10 Dec 17 03:12:17 maya /bsd: sd0 detached Dec 17 03:12:17 maya /bsd: scsibus0 detached Dec 17 03:12:17 maya /bsd: umass0 detached Dec 17 03:12:23 maya /bsd: ehci_idone: ex=0xd0f7b700 is done!
