|
||
* FUNCTION: cqd_ClearTapeError
|
||
*
|
||
* PURPOSE: To correct errors in the Jumbo B drive and firmware version 63.
|
||
*
|
||
* This piece of code added due to the face that the Jumbo B drives
|
||
* with firmware 63 have a bug where you put a tape in very slowly,
|
||
* they sense that they have a tape and engage the motor before the
|
||
* tape is actually in. It may also cause the drive to think that
|
||
* the tape is write protected when it actually is not. Sending it
|
||
* the New tape command causes it to go through the tape loading
|
||
* sequence and fixes these 2 bugs.
|
||
*
|
||
