Scratch that -- operator failure. ;)
The patch makes no difference over hibernates in the SMART logs.

It's still logging extra Power-Off_Retract_Count pegs,
which it DID NOT USED TO DO not so long ago.

Now I'll poke at the shutdown again.

Meanwhile, Stephen: Could you try without this line in the patched file:

case ATA_16:
+ dev->needs_sync_cache = 1;

Ie. comment out that last "dev->needs_sync_cache" line.




No joy - even with that line commented out I get a click and my
Power-Off_Retract_Count has incremented.




I found a solution of sorts on Fedora 6:


Edit /etc/rc0.d/S01halt, changing the third-from-last line so it reads:

HALTARGS="-d -h -n"

Then use the halt(8) command to shut down and turn off the power manually.
No click and the "retract" counter does not increment. (Even this procedure
incremented the counter until I changed the script.)

Seems safe, using the IDE drivers, since they sync the cache anyway.




Hi Chuck,

I got a chance to try this and it works for me also. No pop and my retract counter does not increment.

Steve
