i found a workaround: the device can be removed using the sysfs: source: "SCSI - Hot add, remove, rescan of SCSI devices" http://www-941.ibm.com/collaboration/wiki/pages/viewpage.action?pageId=3625
in short: 1. umount all partitions from the device 2. find the right SCSI ID with "cat /proc/scsi/scsi" 3. replace the SCSI ID in the following command (use tab completion ;): "echo 1 |sudo tee -a /sys/bus/scsi/drivers/sd/2\:0\:0\:0/delete" -- poor handling of eSATA drives https://bugs.launchpad.net/bugs/139748 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
