237 "No rewind" refers to the omission of the default

239 ioctl()'s can be used to rewind the tape regardless of
240 the device used to access it.

2813 The OnStream SC-x0 SCSI tapes do not support the
2814 standard SCSI SASD command set and therefore need
2815 their own driver "osst". Note that the IDE, USB (and
2816 maybe ParPort) versions may be driven via ide-scsi or
2817 usb-storage SCSI emulation and this osst device and
2818 driver as well. The ADR-x0 drives are QIC-157
2819 compliant and don't need osst.
