- 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.
