Talk:Problem with APS harddisk parking

From ThinkWiki
Jump to: navigation, search

What is meant with "frequent drive spin downs", or better: in which interval would the drive spin down? I also get the...

kernel: idedisk_issue_protect_fn(): unload support NOT reported by drive!..
kernel: ide_protect_queue(): head park not requested, used standby!..
kernel: ide_unprotect_queue(): No pending I/O, re-enabling power management..

...error every time I tilt my Laptop (only if hdapsd is running of course) but then I can hear how the head parks and the drive spins down and comes back again. If I don't hear this frequently, there shouln't be any problems right?

My Thinkpad:

Model: R51

HDD: Model=FUJITSU MHT2060AT, FwRev=8423

the hdd is the original shipped one so is has this capabilities.

So maybe anyone can confirm this and add the MHT2060AT drive to the "Drives which have this problem" list

You can check the drive's spec for the rated number of spin-ups to get concrete numbers, but what you describe means that if you work on an unstable surface (lap, train, etc.), you may kill your drive pretty quickly.

Random freezes

My system randomly freezes when slightly shaken, but only from time to time and when hdapsd is active. The last messages in /var/log/messages are:

Jul  8 16:25:09 tp43 kernel: ata_scsi_issue_protect_fn(): unload support reported by drive..
Jul  8 16:25:09 tp43 kernel: scsi_protect_queue(): head parked..
Jul  8 16:25:10 tp43 kernel: scsi_unprotect_queue(): No pending I/O, re-enabling power management..

after that I need a hard reboot.

I use SuSE 10.1 with kernel from, patched with the hdaps-Patch for 2.6.16 (Thinkpad T43). Do I need an earlier kernel version? Anyone else with this problem? HD-Firmware is MB41A60A, and there was no update available.
