After mounting a hard disk, you may need to pause the disk rotation to
mount it on another slot. If so, wait about 60 seconds after you mounted
the disk, before stopping the disk rotation. The operating system executes
the Hot Plug process when the disk is mounted. Therefore, if you
immediately stop the disk rotation, the following error may occur.
kernel: Device sdb not ready.
kernel: end_request: I/O error, dev sdb, sector 204706
kernel: Buffer I/O error on device sdb1, logical block 6396
