|

*
|
||
* FUNCTION: cqd_PrepareTape
|
||
*
|
||
* PURPOSE: Write the reference bursts and get the new tape information
|
||
* in preparation for a format operation.
|
||
*
|
||
* HISTORY:
|
||
* $Log: J:\se.vcs\driver\q117cd\src\0x11015.c $
|
||
*
|
||
* Rev 1.11 24 Jan 1996 10:55:42 BOBLEHMA
|
||
* Changed the format code defines to be more understandable.
|
||
* QIC_FLEXIBLE to QIC_FLEXIBLE_900, QIC_FLEXIBLE_550 to QIC_FLEXIBLE_550_WIDE.
|
||
*
|
||
* Rev 1.10 04 Oct 1995 11:00:32 boblehma
|
||
* Verbatim cartridge code merge.
|
||
*
|
||
* Rev 1.9.1.1 14 Sep 1995 13:06:40 BOBLEHMA
|
||
* Make sure the firmware has the correct number of segments on a T1000
|
||
* and a long tape (307.5 foot).
|
||
*
|
||
* Rev 1.9.1.0 06 Sep 1995 16:20:02 BOBLEHMA
|
||
* Disable Qic 40 support for the Verbatim 1000 foot tape. Disable support
|
||
* for the Verbatim 1000 foot tape on a Jumbo B (FW 63, 64).
|
||
*
|
||
* Rev 1.9 26 Jan 1995 14:59:42 BOBLEHMA
|
||
* Added support for Phoenix and Travan tapes.
|
||
*
|
||
* Rev 1.8 09 Dec 1994 09:31:32 MARKMILL
|
||
* Added a call to the new function cqd_SetXferRates prior to setting the speed
|
||
* via cqd_CmdSetSpeed. This updates the cqd_context with the fastest and
|
||
* slowest supported transfer rates. Since the reference burst was just
|
||
* written on the tape, the previous values may be invalid (e.g. the tape
|
||
* may have been changed from a QIC-3020 to a QIC-3010).
|
||
*
|
||
* Rev 1.7 23 Nov 1994 10:10:18 MARKMILL
|
||
* Added call to new function cqd_SelectFormat to select the format on
|
||
* QIC-3010 and 3020 drives.
|
||
*
|
||
* Rev 1.6 06 Sep 1994 14:21:30 BOBLEHMA
|
||
* Added code to check what media is being used before the reference burst
|
||
* is written. 425 ft tapes should error out before reference burst.
|
||
*
|
||
* Rev 1.5 30 Aug 1994 10:13:58 BOBLEHMA
|
||
* Changed the parameter passed to cqd_SetFWTapeSegments. The local variable
|
||
* can't be used because for tapes we are happy with (segments is ok), the variable
|
||
* will remain zero. Use the tape_cfg data to get the actual segment number.
|
||
*
|
||
* Rev 1.4 29 Aug 1994 12:06:36 BOBLEHMA
|
||
* Changed code to check after the write reference burst if the drive is a
|
||
* QIC_SHORT load point. These tapes must write segments data to the firmware.
|
||
*
|
||
* Rev 1.3 05 Jan 1994 10:43:00 KEVINKES
|
||
* Cleaned up and commented the code.
|
||
*
|
||
* Rev 1.2 08 Dec 1993 19:08:16 CHETDOUG
|
||
* renamed xfer_rate.supported_rates to device_cfg.supported_rates
|
||
*
|
||
* Rev 1.1 08 Nov 1993 14:02:28 KEVINKES
|
||
* Removed all bit-field structures, removed all enumerated types, changed
|
||
* all defines to uppercase, and removed all signed data types wherever
|
||
* possible.
|
||
*
|
||
* Rev 1.0 18 Oct 1993 17:22:36 KEVINKES
|
||
* Initial Revision.
