Comment (by tonestone57):

 If you believe problem with ATA stack then why not build with IDE stack
 and test with that?

 Try with[[BR]]
 HAIKU_ATA_STACK = 0 ;

 That way can see if that is at fault or not.[[BR]][[BR]]

 >''I suppose one possibility might be that Haiku is too fast :) ie: shuts
 down too quickly for the disk to go idle and do its things.''[[BR]]

 I was thinking the same.  Maybe the disk shuts down before the head can
 get to the proper position? ie, the drive head should get parked before
 the OS shuts off.
