>Environment:

Intel DX-II/66, Adaptec 1542CP, Sony SDT-5000

>Description:

The SCSI tape driver code does not leave enough time for "long" erase times
such as those required for DAT tape.

>How-To-Repeat:

Do an 'mt erase' on a dat and wait.

>Fix:
	

In st.c change line #1878 (within the st_erase() function) to read:

immed : 5000 ? 12000000,

This allows up to 200 minutes for tape erase and makes the problem go away.
