I have alot of tv shows recorded to my computers various 8 hard drives. Yesterday on a normal start the boot sequence showed the computer was going thru and finding many “invalid file structure” and was “replacing invalid security ID” ((errors zooming by too fast to really read any more detail)). When the machine finally started, about 20% of the recorded shows on one of the hard drives showed the episodes name but had a file size of zero.
The hard drive had been recently defragged and no viruses have been reported. Yesterday it was 20 Gigabytes lost on one hard drive but I fear that the same thing could happen tomorrow with all my hard drives and with all my data?? I’ve googled this a bit and don’t find anything on point although it sounds like maybe the master file table got corrupted somehow and the rebuild from the mirrored master file table also partially failed???
Anyhow, any ideas on what did happen and how to prevent it??? Is Raiding all my drives the “best” protection against this?? I’ve been thinking of building a Raid 5 system for recording but am very concerned that a controller failure would wipe out “ALL” data. All very frustrating. — Anybody have similar experience even if the “cause” is not known? Thanks. //// Bobbo.
