How do you diagnose problems with tape drives and/or autochangers?

TapeAlert is the street-name for the ANSI specification that governs hardware diagnostics for tape drives, libraries and autochangers.  It was “invented” by HP, and well established as an industry spec.  Pretty much everything from IBM half-million dollar robotic systems to consumer-class entry-level DAT drives from HP support the spec.  More information on the spec can be found at the TAPEALERT.ORG Read more…

Google released a study of 100,000 consumer-class ATA disk drives that revealed a wealth of information including S.M.A.R.T. data analysis; drive temperature vs. disk failure rates; annualized failure rates; and survival probabilities.

Disk drive temperature coolers may be waste of money.

These charts from the google study of 100,000 consumer-class ATA disk drive study show that you are probably throwing money away on disk drive coolers, as disks fail more often at LOWER temperatures. At the very least, have the drive cooling vendors supply data that proves that cooler disk drives last longer. :) Read more…
