- Short: Iomega JAZ tools
- Author: thor@math.tu-berlin.de (Thomas Richter)
- Uploader: thor@math.tu-berlin.de (Thomas Richter)
- Version: 0.16
- Type: util/cli
- Requires: Os 2.04, A jaz drive (guess what...)
-
-
- This program provides functions available thru the Iomega "JazTools" on
- Mac and PC, like setting the spindown delay, ejection of cartridges and
- more. Unlike the ZJTools, this program really works within its
- specifications... (-:
- _____________________________________________________________________________
-
- This is a beta release. Actually, everything works as it should, and every-
- thing has been tested, but the program is still somewhat incomplete. Since
- I do not own a JAZ drive, I need your help!
-
- What's to be done: Actually, only one thing, namely the DISKSTATUS
- option. It does already work, but not in the ideal
- way. It takes just too long to obtain the status, as
- there is an Iomega specific command to do the same
- much faster. I do not yet know how to use it, though.
-
- How to help me: I need detailed information about "rather bad" JAZ
- media whose life time is below 99%, as printed by
- the original Mac JAZTools. Furthermore, SCSIQuery
- is required, and a Mac emulator, like ShapeShifter,
- to run the original JAZTools.
- You find this program either on my home page, or in
- the Aminet. Then, please do the following:
-
- Load the Mac emulator and the original JazTools. Check the disk life time
- remaing, using the original Iomega provided tool. To help me, this should be
- 98% or worse. Please write down the numbers, both, the life time remaining
- and the current disk state. Afterwards, please use the SCSIQuery command on
- the same media, and please sent me its printout, and the two numbers read
- from the original tool. This might help me to test where this information is
- kept. Thanks a lot!

- Announcement: JAZ drivers for the Amiga.
-
- If there is enough interest, I will write a more complete JAZTools program
- than this, including a disk driver, a small JAZ-optimized disk cache, im-
- plementing JAZ specific functions more JAZ-compliant than this product.
- More specifically, the "write verify" will be implemented correctly, the
- spindown timer will work correctly, and you'll see a graphical user inter-
- face for a collection of JAZ tools. The problem with this stand-alone tool
- is, that due to how the JAZ works, not all functions are really available.
- The SCSI interface is a bit different than that for usual devices.
-
- The price for the product would range from $20 to $30.
-
- If you're interested in such a tool and would buy it, please let me know.
- If there is enough interest, I'll start the work. PLEASE DO NOT YET send
- money.

- Synopsis:
- JazTools HANDLER=DEVICE/A,UNIT/K/N,FLAGS/K/N
- SPINDOWN/K/N,PRINTSPINDOWN/S,
- DISKID/S,DISKSTATUS/S,DRIVEID/S,PRINTPROTECT/S,
- EJECT/S,START/S,
- VERIFY/K,PASSWORD/K,
- WPROTECT/S,RWPROTECT/S,
- UNPROTECT/S,TEMPUNPROTECT/S,
- IOEXTEND/K,
- EJECTDELAY/K/N,STARTDELAY/K/N,
- FLUSHDELAY/K/N,INHIBITDELAY/K/N,
- QUIET/S
-
-
- HANDLER=DEVICE/A: Either the name of the AmigaDos device like JAZ: or
- JH0: the Jaz is mounted as, with a colon at the end.
- Alternatively, the name of the exec device driver
- if the drive is not mounted, like "scsi.device",
- "oktagon.device" or "gvpscsi.device".
- If you specify the drive by its exec device driver,
- you MUST give a unit as well, and the JazTools will
- not check whether the device is mounted and available.
-
- UNIT/K/N: If the JAZ was specified by its exec device driver,
- this is the SCSI Unit ID of the Jaz.
- This information is not required if you specified
- the drive by its AmigaDos device name.
-
- FLAGS/K/N: A flags value for opening the exec device driver,
- only looked at if the JAZ was specified by its exec
- driver name and ignored otherwise. This defaults to
- 0, and is usually not required at all. Some device
- drivers check the SCSI bus again if the flags value
- is set to 1 and hence might be able to detect a
- JAZ which was powered on later.
-
- SPINDOWN/K/N: Sets the spin-down delay for the specified unit, in
- minutes. Valid numbers range from 1 to 60 minutes.
- The JAZ calculates the spindown time by counting the
- TEST_UNIT_READY commands, expecting one every second.
- Unfortunately, the Amiga sends them more often making
- a JAZ-minute approximately 50 seconds long.
-
- If the argument is 0, the current spindown setting
- is printed.
-
- *This command depends on device driver internals,
- the spindown time will not be set 100% correctly,
- or might fail to be set at all. A true JAZ device
- driver will make this working*
-
- PRINTSPINDOWN/S: Prints the spindown time in minutes.
-
-
- DISKID/S: Prints unique cartridge ID. I don't know what
- this could be used for.
-
- DISKSTATUS/S: Prints the disk life remaining, estimated by the
- number of bad blocks the JazTools program finds
- on the cartrigde, and the current disk status.
- The first number is the amount of permanent bad
- blocks, the second number is the amount of bad
- blocks that could be recovered by re-formatting
- the cartridge.
-
- *This command does not yet use the Iomega specific
- commands to read the diskstatus. It might take
- approximately 15min to get the information.
- I need your help to implement this correctly, see
- the introduction*
-
- DRIVEID/S: Prints the INQUIRY information of the drive, like
- the vendor and version information.
-
- PRINTPROTECT/S: Prints the protection status of the cartridge.
-
- EJECT/S: Ejects the cartridge. If the drive was specified
- by its AmigaDos device name, the JazTools check
- whether the device is available to AmigaDos and
- fail in case it's not. Hence, if you want to
- eject an unmounted cartdrige, specifiy the JAZ by
- its exec device name and its SCSI ID.
-
- START/S: Restarts the drive in case it was parked, either
- automatic or manually.
-
- VERIFY/K: Takes an argument, either "on" or "off". This
- *might* enable the automatic verify, at least
- partially.
-
- *This command is not implemented 100% correctly,
- it enables a verify bit in the JAZ, but does not
- enforce the use of the correct write command.
- Therefore, the drive might not verify as expected,
- or might even do worse. A true write verify function
- can't be implemented without a JAZ specific device
- driver, which would adjust the write command sent
- to the device according to the verify status.
- Moreover, a final edition might implement a software
- verify bit which might mean less stress for the
- medium*
-
- PASSWORD/K: This option provides a password, required for various
- suboptions below.
-
- WPROTECT/S: Write-protect a medium. A password is optional.
- If a password is given, the same password is
- required to unlock the medium again.
-
- RWPROTECT/S: Lock a medium for reading and writing. The password
- is mandatory, i.e. it won't work without.
-
- UNPROTECT/S: Unprotect a medium, remove the read or write
- protection. A password may or may not be required,
- this depends on whether a password was given when
- the volume was locked.
-
- TEMPUNPROTECT/S: Unprotect a medium temporarely, it will get locked
- again as soon as it is removed again. Except for
- that, this option is identically to UNPROTECT.
-
- IOEXTEND/K: Enables or disables Iomega specific functions of
- the drive I've no great idea about. The argument
- should be either "on" to enable them or "off" for
- disabling them.
-
- *Currently, this shouldn't really make a difference*
-
- EJECTDELAY/K/N: A delay in fifties of a second ("Ticks") before the
- JAZ is made available to the filing system again
- after ejection, required for the JAZ to settle down.
- Defaults to 50, i.e. one second.
-
- STARTDELAY/K/N: Currently not yet used.
-
- FLUSHDELAY/K/N: A delay in fifties of a second to allow the filing
- system to swap out its buffers before ejecting the
- device. This is an ugly and uneffective workaround
- against a bug in the FFS. (ACTION_FLUSH is not
- implemented correctly)
- Defaults to 150, i.e. 3 seconds.
-
- INHIBITDELAY/K/N: A delay in fifties of a second after locking the
- device from the filing system and before allowing
- other operations, required for the filing system to
- settle down.
- Defaults to 100, i.e. 2 seconds.
-
- QUIET/S: Disables printing the copyright message.
