_____________________________________________________________________________
Changes made for 1.34:
- Fixed some typos.
- The read-capacity with non-zero PMI flag is now
initiated from the start of the disk, similar to
HDToolBox. This should return a data related to the
track size.
_____________________________________________________________________________
Changes made for 1.33:
- Some cosmetical changes in the output format.
- The Iomega specific field "Format count" was incorrectly printed as
"BadFlag". Fixed.
_____________________________________________________________________________
Changes made for 1.32:
- Added more support for Iomega, mainly JAZ related.
_____________________________________________________________________________
Changes made for 1.30:
- Fixed a bug for the notch page output.
- Added notch support, can be disabled with the NONOTCHES option.
_____________________________________________________________________________
Changes made for 1.21:
- Disabled one error check when getting the extended inquiry data. Some
old device drivers seem to fail getting them correctly. I can't reproduce
this.
_____________________________________________________________________________
Changes made for 1.20:
- Fixed a *fatal* bug that could have caused really serious crashes.
Forgot to cast correctly, leading trashing innocent memory. Outch!
*Sorry, sorry, sorry, sorry!*
- Enhanced the Iomega extension output.
_____________________________________________________________________________
Changes made for 1.19:
- Made the defect list format selectable, with autoselect for Iomega.
- SCSIQuery prints now the extended INQUIRY data.
- SCSIQuery detects now automatically whether a device name or a DOS
device driver is given.
_____________________________________________________________________________
Changes made for 1.18:
- Added more sanity checks, fixed a possible enforcer hit. Thanks to
Gene Heskett for reporting.
- Changed the bad block default format to head/sector addressing rather
than bytes from index. This avoids trouble with Iomega devices.
_____________________________________________________________________________
This tool prints all internal information of a SCSI device it can hold
of, including the mode pages and the bad block lists. This might be
interesting for developers of SCSI software and hardware.
SCSIQuery replaces the older ProbSCSI which doesn't seem to run stable under
certain (and in some sense broken) hardware, like the CyberSCSI device
which doesn't seem to follow the RKRMs on each word.
Features:
- Prints the device inquiry status
- Prints SCSI mode pages by their structure. It knowns most
HD and CD rom pages, and unknown pages are printed in hex dump.
- Prints the device capacity.
- Prints the defect list.
- Knows some Iomega extensions, most noticable for ZIP and JAZ.
However, this is far from being complete due to the strange
information policy of Iomega.
- tested on the gvpscsi.device, the oktagon.device and the
(cyber)scsi.device. Should work on every device that follows
the RKRMs scsi.device documentations (roughly, at least).
To do:
Quite a lot, actually. However, it doesn't look I'm gonna have a
lot of time to develop this program further. It currently does what
it is supposed to do, but could do a lot better.
- A GUI is missing. I'm just to lazy to write one in the current
state of this program.
- SCSIQuery doesn't allow to change or save the mode pages.
- Only mode pages for HD and CD are supported, no scanner/printer/
floptical and other SCSI device support. More mode pages might
be added on request.
- No LOG PAGES support yet.
- The readme is really a bit unhelpful. This program really lacks
a full detailed guide. However, lack of time... (-;
Additional note:
Requests about what the output of this program means ARE NOT welcome. The
SCSI-II specifications are available in public and they include all this
information.
WANTED - WANTED - WANTED - WANTED - WANTED - WANTED - WANTED - WANTED - WANTED
More SCSI mode page informations. I'm able to implement all official pages
of the SCSI-II specifications since I've a copy of the SCSI specifications,
however, there are more, vendor specific pages I've no idea about. Getting
hold of the Iomega specifications - not the output of the program -
would really, really help.
If you've ANY information about these (not the official SCSI-II pages!)
additional pages, please, please PLEASE LEMME KNOW!

Installation:
Just copy it whereever you want to keep it. Needs nothing more.
Synopsis:
SCSIQuery HANDLER=DEVICE/A,UNIT/N,FLAGS/N,DEFECTLIST/K,NONOTCHES/S
HANDLER=DEVICE the name of the DOS handler controlling a SCSI
device. DO NOT specify handlers that are not
linked to SCSI devices, this will either abort
with an error message in the best case, or crashes
the system in the worst case. You *HAVE TO* place
a trailing colon ":", e.g. "ZIP:".
Alternatively, an exec style device, it *MUST*
end with ".device", e.g. "omniscsi.device"
UNIT the unit of the exec device to investigate, required
if an exec device name was specified.
FLAGS flags used for opening the specific device;
defaults to zero and are not required in most cases.
DEFECTLIST the type of defect list to inquiry from the device.
Possible defect list specifiers are:
OFF Do not print a defect list.
INDEX Specify defaults as bytes from an index on
the tracks.
PHYSICAL Specify defaults as physical head, cylinder
and block.
BLOCK Specify defects as block offsets from the
start of the drive.
DEFAULT Use the INDEX method for all drivers except
for Iomega devices which use the PHYSICAL
type.
NONOTCHES disables notch specific information. In case
SCSIQuery finds that the device to be investigated
has more than one notch, SCSIQuery will try to
print the notch dependent information separately
for each notch available.
Examples:
To investigate your system partition, try:
SCSIQuery DH0:
To print information about your CD ROM, try:
SCSIQuery CD0:
To query the SCSI device connected to the "gvpscsi.device", unit 6, try:
SCSIQuery gvpscsi.device UNIT=6
To query the SCSI device connected to the "oktagon.device", unit 0, try:
SCSIQuery oktagon.device UNIT=0
