- ***************************************************************************
- *** Purpose ***
- ***************************************************************************
-
- DiskInfo is a tool which can be used to display information about any
- Amiga storage media, including disks, hard disks and memory. Eventually it
- will be worthy of completely replacing the Workbench "Info" command. It can
- be executed as an AmigaDOS command from the Workbench or Shell.
-
-
- ***************************************************************************
- *** Requirements ***
- ***************************************************************************
-
- For this program to operate properly, you must have the following:
- (*) An Amiga (any model)
- (*) Workbench 2.04
- (*) A working knowledge of the Workbench and Shell environments
- (*) This program
-
-
- ***************************************************************************
- *** Usage ***
- ***************************************************************************
-
- This program may be executed from the Workbench using the "Workbench/
- Execute Command..." option, or from the Shell. Usage is the same from either
- environment:
- DiskInfo <Device>
-
- The "<device>", of course, is the name of any storage device or volume.
- Further arguments are not present in this version of the program. If no
- device is specified, the following will be displayed:
-
- DiskInfo (Version 1.13) by Gregg Giles
- Purpose: Gives a complete status report on any mounted AmigaDOS device.
- Usage : DiskInfo <Device>
-
-
- ***************************************************************************
- *** Usage Examples ***
- ***************************************************************************
-
- These examples assume that you have booted from your Workbench 2.04
- distribution disk, and your Extras disk is in DF1:. Issue this command:
-
- 1> DiskInfo DF0:
-
- Most information of interest to the average user will be displayed, and
- will appear like this (or similar to it):
-
- Name : Workbench2.0: Errors : 0 Bytes Blocks
- Status: Write Protected Full : 94 % Size: 857904 1758
- Type : AmigaDOS OFS In Unit: 0 Used: 808128 1656
- Block : 488 bytes In Use : Yes Free: 49776 102
-
- Issuing the following command will show what resides on the Extras disk:
-
- 1> DiskInfo DF1:
-
- Something similar to the following will appear:
-
- Name : Extras2.0: Errors : 0 Bytes Blocks
- Status: Write Protected Full : 84 % Size: 857904 1758
- Type : AmigaDOS OFS In Unit: 1 Used: 726144 1488
- Block : 488 bytes In Use : Yes Free: 131760 270
-
- This, of course, is assuming that no errors occur. Further explanation
- of each field can be found later in this document. Other examples of using
- DiskInfo include:
-
- Command Description
- ----------------------------------------------------------------------------
- DiskInfo DF0: Shows information about disk in unit 0 (DF0:)
- DiskInfo DF1: Shows information about disk in unit 1 (DF1:)
- DiskInfo DF2: Shows information about disk in unit 2 (DF2:)
- DiskInfo DF3: Shows information about disk in unit 3 (DF3:)
- DiskInfo DH0: Shows information about hard disk partition DH0:
- DiskInfo DH1: Shows information about hard disk partition DH1:
- DiskInfo RAM: Shows information about the RAM: disk
- DiskInfo RAD: Shows information about the RAD: disk
- DiskInfo Extras2.0: Shows information about a volume named "Extras2.0"
- DiskInfo Pictures1: Shows information about a volume name "Pictures1"
-
- Logical devices created using the "Assign" command may be used in place
- of a physical storage device (ie: "c:", "libs:", "devs:", etc.) However, in
- such cases, information about the physical media on which that logical
- device resides will be displayed.
- For example, assuming you booted from your Workbench 2.04 distribution
- disk, use this command and view the ensuing results:
-
- 1> DiskInfo C:
-
- Name : Workbench2.0:C Errors : 0 Bytes Blocks
- Status: Write Protected Full : 94 % Size: 857904 1758
- Type : AmigaDOS OFS In Unit: 0 Used: 808128 1656
- Block : 488 bytes In Use : Yes Free: 49776 102
-
- Notice that the "name" field gives the complete path to the logical
- device specified.
-

- ***************************************************************************
- *** Explanation of Fields ***
- ***************************************************************************
-
- The program displays rougly a dozen fields when executed (assuming there
- are no errors). They are described as follows.
-
- Field : NAME
- Purpose : Name of the disk (or volume) being examined.
- Output : A valid Amiga disk name. If a logical device name is given, a
- full path name will be displayed.
-
-
- Field : STATUS
- Purpose : Physical status of the disk.
- Output : Possible results include:
-
- "Write Protected":
- Disk is write protected. (Formerly "Read Only" in program versions).
- "Validating":
- The disk's structure has been corrupted, and AmigaDOS is attempting
- to correct the problem.
- "Validated (Writable)":
- The disk's structure is stable, and thus can be written to or read
- from. (Formerly "Read/Write" in earlier program versions).
- "Unknown":
- The disk's status cannot be determined.
-
-
- Field : TYPE
- Purpose : Type of disk.
- Output : Possible results include:
-
- "AmigaDOS OFS":
- A standard AmigaDOS OFS disk (Old File System). All disks formatted
- using "Format" command under Workbench 1.0-1.3 were OFS format disks
- (Workbench 2.0 will read/write/format OFS disks.)
- "AmigaDOS FFS":
- A standard AmigaDOS FFS disk (Fast File System). Most likely a disk
- created using the "Format" command under Workbench 2.00 and later
- versions.
- "Unknown (????)":
- The format of the disk cannot be determined. Possibly a disk format
- not known about at the time of the creation of this program.
-
- Note: Subsequent versions of this program may be able to recognize the
- following disk types: BAD (unreadable/corrupted), KICK (Amiga Kickstart
- disk), NDOS (Format of the disk is good, but it does not use any known
- AmigaDOS format; possibly a proprietary file format such as those often
- used as copy protection for games).
-
-
- Field : BLOCK
- Purpose : The number of bytes that compose one block on the disk.
- Output : A positive numeric value.
-
-
- Field : ERRORS
- Purpose : Number of read/write errors on the disk.
- Output : A positive numeric value.
-
-
- Field : FULL
- Purpose : Percentage of the disk which is full.
- Output : A positive numeric percentage (rounded off).
-
-
- Field : IN UNIT
- Purpose : AmigaDOS unit number in which the disk resides.
- Output : Possible results include:
-
- -1: The RAM: device
- 0 : Floppy disk DF0:
- 1 : Floppy disk DF1:
- 2 : Floppy disk DF2:
- x : Any unknown unit number, where (x) is the number of that unit.
- (Note: Some hard disk partitions may appear as unit 0.)
-
-
- Field : IN USE
- Purpose : Message telling if the disk is currently in use.
- Output : Possible results include:
-
- "Yes": The disk is in use.
- "No" : The disk is not in use.
-
-
- Field : SIZE (BYTES)
- Purpose : Total byte storage capacity of the disk.
- Output : A positive numeric value. Note that this is the total actual
- storage possible. The Amiga file system will reduce the total
- available free storage space.
-
-
- Field : SIZE (BLOCKS)
- Purpose : Total block storage capacity of the disk.
- Output : A positive numeric value.
-
-
- Field : USED (BYTES)
- Purpose : Number of bytes of the disk which have been used.
- Output : A positive numeric value.
-
-
- Field : USED (BLOCKS)
- Purpose : Number of blocks of the disk which have been used.
- Output : A positive numeric value.
-
-
- Field : FREE (BYTES)
- Purpose : Number of bytes of the disk which are not yet used.
- Output : A positive numeric value.
-
-
- Field : FREE (BLOCKS)
- Purpose : Number of blocks of the disk which are not yet used.
- Output : A positive numeric value.

- *** Program Integrity & Bugs ***
- ***************************************************************************
-
- It is the author's goal to keep this program as stable, correct, and as
- bug-free as possible. For this reason it employs careful error checking
- techniques, particularly when dealing with locks and memory. Everything
- which is opened is closed, even when errors occur. As an Amiga user
- himself, the author loves cleanly written programs, particularly those
- that don't suck up system resources when they screw up.
- This program has its own built-in error messages, and all are largely
- self-explanitory. These error messages generally only appear when the
- user has done something incorrectly (ie: trying to examine a disk in a
- drive when no disk is present).
- However, should you discover any bugs in this program, please record them
- and contact me immediately so that they may be corrected and the fixed
- version of the program released.
-

- ***************************************************************************
- *** Revisions & Planned Enhancements ***
- ***************************************************************************
-
- Planned Enhancements:
- * Wildcards, including the AmigaDOS wildcard combination (#?) and the
- well-liked asterisk (*) familiar to UNIX, MS-DOS, and Amiga ARP users.
- * Enable recognition of disk formats other than AmigaDOS.
- * Enable display of all mounted devices simultaneously, much like the
- AmigaDOS Info command when used with no flags.
-
- The following changes have been made to this program since the previous
- version:
-
- * Now using official 2.04 #defines for return codes instead of self-defined
- return codes of 1.12. Makes program a little smaller.
- * Device lock changed from ACCESS_READ to new synonomous SHARED_LOCK.
- * Error checking code streamlined. Makes program a little smaller.
- * Error messages improved; now use Workbench 2.04 messages from IoErr().
- * Breaking with Control-C is now impossible; prevents dangerous situations.
