|
||
*
|
||
* HISTORY:
|
||
* $Log: J:\se.vcs\driver\q117cd\src\0x11018.c $
|
||
*
|
||
* Rev 1.10 24 Jan 1996 10:59:18 BOBLEHMA
|
||
* Added support for 3010 and 3020 wide tapes.
|
||
*
|
||
* Rev 1.9 05 Oct 1995 14:15:20 boblehma
|
||
* Grizzly code merge.
|
||
*
|
||
* Rev 1.11.1.3 14 Sep 1995 13:07:30 BOBLEHMA
|
||
* Make sure the firmware has the correct number of segments on a T1000
|
||
* and a long tape (307.5 foot).
|
||
*
|
||
* Rev 1.11.1.2 06 Sep 1995 16:18:08 BOBLEHMA
|
||
* Added support for the Verbatim 1000 foot tape. On a T1000, DON'T change the
|
||
* segments per track found by the calibrate if it is a 1000 foot tape.
|
||
*
|
||
* Rev 1.11.1.1 16 Aug 1995 16:29:06 TRACYBAI
|
||
* When checking to determine how many seg/track to set for a fixed length
|
||
* tape that has been calibrated in a drive with fw >= 128, added some slop
|
||
* on the other end so that tapes that are calibrated with sligthly less
|
||
* seg/track than the nomimal value get formatted correctly.
|
||
*
|
||
* Rev 1.11.1.0 15 Aug 1995 10:32:34 BLDMACH2
|
||
* Merge of Bob's changes into GRIZWIN
|
||
*
|
||
* Rev 1.13 26 Jul 1995 13:27:08 BOBLEHMA
|
||
* Make sure a calibrate is done for all flex tapes (including QIC 80).
|
||
*
|
||
* Rev 1.12 27 Jun 1995 12:34:48 BOBLEHMA
|
||
* Removed call to cqd_PrepareIomega3010PhysRev. Firmware bug is now fixed
|
||
* by calling stop tape instead of pause tape in the cqd_ProcessFRB function.
|
||
*
|
||
* Rev 1.11 21 Feb 1995 17:09:20 BOBLEHMA
|
||
* Bonehead. I forgot to uncomment the code that forces the number of
|
||
* segments per track to the spec values for DC2000, DC2120, and DC2120 XL.
|
||
*
|
||
*
|
||
* Rev 1.10 30 Jan 1995 14:24:38 BOBLEHMA
|
||
* Changed device_descriptor.version to cqd_context->firmware_version.
|
||
*
|
||
* Rev 1.9 27 Jan 1995 13:22:22 BOBLEHMA
|
||
* Added a call to cqd_PrepareIomega3010PhysRev before the call to
|
||
* the firmware function Calibrate Tape Length. Note that this function
|
||
* is a NOP if the drive is not an Iomega 3010.
|
||
*
|
||
* Rev 1.8 26 Jan 1995 14:59:54 BOBLEHMA
|
||
* Do calibrate tape length for firmware >= 128. For long and short load point
|
||
* tapes, the segments need to be adjusted back to the spec values and set
|
||
* in the firmware.
|
||
*
|
||
* Rev 1.7 02 Sep 1994 15:10:44 BOBLEHMA
|
||
* Removed check for CMS drives with firmware < 60 before a retension. For
|
||
* the 425 foot tapes, we must always retension to get the correct length of
|
||
* the tape.
|
||
*
|
||
* Rev 1.6 29 Aug 1994 12:06:30 BOBLEHMA
|
||
* Changed the interface to cqd_CmdRetension. Added a number of segments parameter.
|
||
*
|
||
* Rev 1.5 17 Feb 1994 11:44:42 KEVINKES
|
||
* Added an extra parameter to WaitCC.
|
||
*
|
||
* Rev 1.4 11 Jan 1994 14:26:22 KEVINKES
|
||
* REmoved an unused variable.
|
||
*
|
||
* Rev 1.3 09 Dec 1993 14:43:02 CHETDOUG
|
||
* Removed set format segments code. This is not needed for qic117
|
||
* and was corrupting the segments per track value returned to the
|
||
* caller.
|
||
*
|
||
* Rev 1.2 08 Nov 1993 14:02:42 KEVINKES
|
||
* Removed all bit-field structures, removed all enumerated types, changed
|
||
* all defines to uppercase, and removed all signed data types wherever
|
||
* possible.
|
||
*
|
||
* Rev 1.1 25 Oct 1993 14:36:22 KEVINKES
|
||
* Changed kdi_wt2ticks to kdi_wt004ms.
|
||
*
|
||
* Rev 1.0 18 Oct 1993 17:22:56 KEVINKES
|
||
* Initial Revision.
