Hi all,
I'm currently running 4 x 2 TB drives in Raid 0 configuration, yes I know its risky. I noticed a ticking noise coming out of the drives and when I rebooted the box, I received the "Error Occured (0)" on 2 of the drives (see the pic). The drives appear to be working fine, but was wondering if this could a Raid issue and not a hardware one?

I'm backing up my data now and am going to rebuild it, but is it possible that its a raid issue? Also would the write speed be affected as I'm getting +- 2 mb/s doing the backup.

Any advice would be grateful.

Thanks
Arri

Anyone?

Hi Arribello,

strange noise, slow copy speed and raid error on two disks. Seems like two of your disks have a mechanical issue. You might check SMART status of the drives with crystaldiskinfo. In such a situation I would try to get the critical files first as long as you can (mp3 ?). Might be the drives will die on too much load. If data is important might be better to get help from a pro that can image the failing drives without too much load (hardware based image).

best regards,
pcn

If drives are fine, but only then you can try: viewtopic.php?f=7&t=29667

So far it's backing up the data, all 700 gigs worth of mp3 files.
Currently at 42%, hopefully it will get to the end.

Thanks for your input.

speed I guess depends on what you are backing up to and what interface.

if you are backing up to something like a single disk, be careful. I have seen many brand new, or good condition disks that were the backup disk when a large amount of data was written in one go.. had it happen to myself twice, but seen it quite a bit.

I normally do it in "chunks" of 20Gb or 30GB max, and because you aren't usually right there to do the next chunk, my theory is the break doesn't hammer the drive constantly for hours. nothing scientific to back it up though, drive failures are at best a guess usually.

Hopefully this little incident will scare you away from RAID0
