WD Netcenter power light flashing amber and cannot access data

Thanks for the suggestion.  As a matter of fact, that is what I ended up doing.  At first, I thought the hard drive had failed but after connecting to an old Pentium 4 tower that had IDE discovered the drive spun up and seemed to be fine.  So, what ever the failure was, it was in the electronics associated with the NAS and not the drive.  I believe you are correct that the drive is formatted as ext3.  I’m attempting to recover the data.  Rather frustrating the backup device you rely on decides to bite the dust.  Now, I guess I will need to backup the backups in the future.  Sure hope my new WD NAS doesn’t decide to crash.  Anyway, thanks for your suggestion and input.
