Physically locate failed disk

Featured Replies

What is the recommended way to physically locate a disk that has failed if they are not labeled?  I thought of booting with knoppix or the like and doing a dd to NULL or something like that which would blink the drive and allow it to be located that way.  Any other advice?

physically look at the drives...   

unplug one, see which is missing when booting up.  rinse, repeat.

Why boot knoppix when you can just boot unRAID.  (or leave it booted and do exactly the same "dd" to /dev/null.)

Makes sense.  I just didn't know how stripped down unRAID might be.

I wound up getting the serial and then pulling disks until I located the disk with that serial.  It was the very last disk after pulling all of them.  :P  Anyway, replaced it and all is well.  Now to send the disk off for warranty replacement.

unRAID assigns disks to "slots" in the array by serial number/model number.  Most people label their drives with all or part of the serial number to make identification easy. 

 

Glad you figured it out.  I hope you took notes when you went through your exorcise and are now able to label your drives.
