Hi all, after unmounting my usb-storage device I unplug this. But there is still a scsi device attached to the system. I also get the following in /var/log/messages ----8<---- kernel: Device not ready. Make sure there is a disc in the drive. kernel: sdb : READ CAPACITY failed. kernel: sdb : status = 1, message = 00, host = 0, driver = 08 kernel: Info fld=0xa00 (nonstd), Current sd00:00: sense key Not Ready kernel: sdb : block size assumed to be 512 bytes, disk size 1GB. kernel: sdb: I/O error: dev 08:10, sector 0 kernel: I/O error: dev 08:10, sector 0 kernel: unable to read partition table devlabel: devlabel service started/restarted ----8<---- Is it neccasary to run any other command then umount before I can unplug such devices? You see, it was attached as sdb. This is because sda is "blocked" by another usb-storage device. I unplugged this other device, and now my second is on sdb. I hope you can help. TIA -- Grüße / regards Sebastian
