Hi all

My Buffalo LinkStation Pro (LS-VL) has stopped working - getting a clicking thing that sounds like a train going over points. I've taken the HDD out and it's doing the same in a caddy, so I'm presuming it's lost. My question(s):

Am I right in thinking that, because this is a single HDD NAS, the NAS's OS/software/config is also lost? Hard drives fail, but I really don't want to lose access to all my music, films etc, so I'd like to be able to quickly recover from it. I was hoping I could just stick another HDD in and it’d be back up and running. No?

If I replace with a 2+ bay NAS, would that make it easier to get back to where I was in future (as in, the OS etc is stored somewhere other than any of the HDDs, so I can just whip out the faulty HDD and stick another one in)?

I know one option is RAID / straight mirroring, but I can't see a lot of point to backing up all my data to a drive in the same unit: can I back up just the NAS OS to another HDD and just copy it onto a new replacement HDD if it fails and be back up and running again?


Thanks


Rob

Usually the OS is stored on a separate NAND chip on the motherboard, or an SSD. Don't really have time to answer the rest.

The music, movies or any other data is stored on the hard drive. If it dies, the data dies with it. The idea behind mirroring is that when a drive fails(like yours) your data is still there - on the other drive, and the failed drive can be replaced and the mirror(drive protection) can be restored.

ISTR that at least some of the NAS firmware/software is stored on the drive in reserved partitions. The NAS OS is usually Linux based.

What is the model number of the drive? Does it remain spinning? Can CrystalDiskInfo see it?
