The mount should be read-only. >1/2" magtape is not in general block-replaceable, unlike DECtape. on a tu-11 a write-gap command can be issued several times after each block. this will allow the tape (modulo murphy's law) to be used for read/write. various dec operating systems (rt-11 comes to mind) use this technique to create tapes which can be booted off of an run. provided the driver skips the interrecord gaps before the next block write, there should be no problem. also, you must NOT write a file mark after the last write to the device. -- John F.
