iMac G5 SATA hard drive keeps disappearing #

Same symptom, different causes:
  1. Question mark on boot. Partition/format drive, run hardware tests (passed), install OS X - OK
  2. After a week or two, question mark returns. Replace SATA cable - OK
  3. After another week or two, question mark returns. Hard drive has failed (verified on another Mac) - install new hard drive and repeat step 1 - OK
  4. After yet another week or two, question mark returns. Set jumper on hard drive to limit feature set to SATA revision 1.0 (SATA 1.5 Gbit/s) - OK (over a month 23 months and counting!)
