If it happens just under Linux, this is something that really needs to be addressed post-haste. Maybe someone should open a bug in bugzilla to help track it properly? If it also happens under Windows, you have been sold defective crap that is being damaged every time you reboot it, get in touch with the manufacturer and demand a replacement *new* unit with a firmware fix, or your money back. > (2) Linux (alone) gives a very muted pop on shutdown. This could Shutdown as in "machine power off", and HDs are under SCSI control (they appear as scsi devices to userspace, due to libata for example)? Known issue, see http://bugzilla.kernel.org/show_bug.cgi?id=7838 (actually, IMHO this fix should have been fast-tracked into 2.6.21, instead of queued for 2.6.22). Shutdown as in reboot/restart? New bug that needs to be stomped as soon as possible, but make sure it is not (1) above. -- "One disk to rule them all, One disk to find them.
