Title: How Tandberg and Archive Drives Act When Reset
Date: 4/9/90

Copyright 3Com Corporation, 1991.  All rights reserved.

When the Tandberg drive arrives at 3Com, it is set with a "zero
delay."  When the power is applied, or when the SCSI bus is
reset, a drive fresh from the factory will do an immediate
"shoeshine" (that is, the tape will move forward and backwards
several times).  After 3Com installs the drive in a server and
the first "mode select" is issued (during backup, for instance),
the drive will forever after have a 20-second delay.  This value
remains in the drive even if the drive is removed from the
server.  The drive will not do a shoeshine for approximately 20
seconds after power is applied or after the SCSI bus reset is
issued.

The Archive tape drive does not do a shoeshine at all.  Instead,
when power is applied or a reset is issued, the drive will make a
slight rattle sound.  This is a head calibration.  Tape motion is
not instigated until a command such as read, write, or erase is
issued.
