We ($WORK) factor the cost of DOA/warranty drives into our operational budget. They never get RMAed. We drill them when they die. Being a personal user, and having close to a 10% RMA rate on recent hard drives, that would be a bit costly... I consider a HD defective if it's under waranty and it's performance drops below 80% of new, i.e. 130MB/sec normal sequential write drops below 100MB/sec.. The weekest point is the passphrase/passfile protecting the master key... In my case, I use a random passfile for these drives... If someone is able to break the passfile, or the AES-256 encryption, then they must really want my data... It'd be easier, even for governments, to do a black bag job than recover partial data (it's one drive of a RAIDZ array)... -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
