-
- Out of the five 200Mb Conner disks that were installed in computers that
- people at my department bought, three died of stiction(*), including mine.
-
- (Twenty Conner disks of lesser capacity have no problems.)
-
- I turned the computer on and banged the drive back into motion with the
- handle of a screwdriver. (I didn't want to go back to the (old) backup,
- and the drive was now worthless anyway.)
-
- Now I could make a decent backup.
-
- After this the disk very reliable refused to spin up after two days of
- standstill, which was good because it is better if you can show your
- vendor a disk that is indeed broken. :-)
-
- (*) "Stiction" is caused by a bad lubricant on the platter surface.
- When the power is turned off the heads are pulled back to the parking
- cylinder where they sink down to the surface of the platters. When the
- power is turned on the lubricant is needed to make the heads slide over
- the surface before the airflow lifts them a little bit. Some disks have
- a lubricant that is not "oily" enough when the drive is cold: Stiction.
