All of my logical drives are in a RAID1 or greater setup. Occasionally (maybe every 6 months) I manually drop a drive then rebuild it, and once that has completed repeat for the other drive(s)
This is intended to rejuvenate data by redoing the magnetic arrangement so that a sector which has a 1% chance of being misread goes back to 0.01% (of course, these are just random figures I've made up to illustrate my point)
I've been looking into how programs like HDD Regenerator and DRevitalize work. Perhaps writing out an intermediate pattern between drop and rebuild may also help preserve the integrity of the sector. Get the flux moving around a bit.
Or is this all just fluff?
Along vaguely similar lines... why can't drives be 100% low level formatted back to factory status with a command or set of commands? Does some other equipment write the initial markers on the platters?
Strange questions at a strange time... it just hit midnight here and I think it's time for bed.
