hi all, I know this doesn't relate to FBSD per se, but I figured i'd try to pick your brains :) I read somewhere (sorry, cant remember where) that hard drives fail if not powered up every so often (not sure of time frames, but the discussion was about tapes still being better for backups than hard drives if planning for long term storage). It was also mentioned a "knock on the centre of the drive" to bring it back to life (??). How much truth is in this? I have EIDE drives that I havent used in years and I just tested them and they work fine...but again, I've had an instance of a new drive, used twice to backup some info and then left untouched for 10 months, and it wouldn't even spin up... Does this affect SCSI drives? I suppose it would be more likely to affect desktop-quality IDE / SATA drives... Any insights will be much appreciated. Best regards, Beto
