TEAC SCSI FLOPPY MODE_SELECT DOC June 29/91
TSFMx.doc for x ={1,2,4} Copyright 1991 by Harvey Taylor
What it is
----------
The TEAC SCSI Floppy needs to have its controller set into different
modes for the various capacity disks it uses. This is accomplished by
sending an appropriate MODE_SELECT command via SCSI Direct.
Command Lines
-------------
You must run TSFMx from the CLI.
TSFM2 ? /* Prints format */
TSFM1 /* USES DEFAULTS */
TSFM4 scsi.device 3
TEMPLATE: TSFMx [xxx.device scsi_id]
The defaults are harddisk.device and 1.
Examples
--------
To use the drive with a 2 Meg disk
1) Mount SD2:
eg. use the command line
1> Mount SD2:
2) SCSI Format with TSFF2
eg.
1> TSFF2
3) AmigaDOS Format
eg.
1> Format drive SD2: name Test.0 noicons quick
(see Note 1)
4) Test if the system sees it
eg.
1> info
1> list sd2:
5) If you change to another 2 Meg disk, you need to do a DiskChange.
eg.
1> diskchange sd2:
6) If you change to a 4 Meg disk, you need to have completed a
similar process for the SD4: and to do 2 DiskChanges and a
TSFM4. (see Note 1)
1> dc sd2: /* tell handler disk changed */
1> tsfm4 /* change mode */
1> dc sd4: /* tell other handler to check disk */
Note 1
It can be useful to set up a couple of aliases for these commands.
In particular:
alias dc DiskChange
alias sd2fmt Format drive SD2: name [] noicons quick
Gotchas
-------
It is very easy to corrupt disks because the FastFileSystem [or the
MSDOSFileSystem] has no way of knowing if you have changed disks. You
either have to be very careful about doing DISKCHANGEs or use TSFADC. This
is a daemon which does occasional Test Unit Readys. If there is a change in
the SCSI status, it sends a disk change packet to the handler.
