drive:
This SCSI controller a single SCSI bus, named ID.0. Put a disk on
it:
- -device scsi-disk,drive=DRIVE-ID,bus=ID.0,scsi-id=SCSI-ID
+ -device scsi-disk,drive=DRIVE-ID,bus=ID.0,scsi-id=SCSI-ID,removable=RMB

+ The (optional) removable parameter lets you override the SCSI INQUIRY
+ removable (RMB) bit for non CD-ROM devices. It is ignored for CD-ROM devices
+ which are always removable. RMB is "on" or "off".

@@ -116,7 +120,12 @@ For USB devices, the old way is actually different:
Provides much less control than -drive's HOST-OPTS... The new way
fixes that:
- -device usb-storage,drive=DRIVE-ID
+ -device usb-storage,drive=DRIVE-ID,removable=RMB
+
+The removable parameter gives control over the SCSI INQUIRY removable (RMB)
+bit. USB thumbdrives usually set removable=on, while USB hard disks set
+removable=off. See the if=scsi description above for details on the removable
+parameter, which applies only to scsi-disk devices and not to scsi-generic.
