ATA errors on one disk, failed other disk
On 6/1/15 I got the following email: Detected increasing ATA errors on disk 4[ST32000542AS, 5XW1M471] 40 times in the past 30 days. This often indicates an impending failure. Please be prepare...
I don't know why the ATA errors don't seem to match the alerts' but ATA errors almost always indicate a failing disk. It's possible that if there are ATA errors on more than one drive in the same slot, then there could be a problem with the drive bay. That's not the case here though.
1 ATA error is significant , AFAIK, drives will be replaced if they have 1 ATA error. The rate of increase is important, some may consider leaving a drive with ATA errors if they are not increasing or increasing very slowly. It depends on your attitude to risk, how important the data is, and how robust and convenient your backups are.
Also not sure about the email alerts. You could look at your logs to see if there were alerts sent which were either not received or there was a problem sending.
The backup issue could have many causes. I would start by looking at the backup configuration to make sure that's right, testing the USB disk, and looking at what's being baked up. You say no data on some days and the job still takes so long. Look at the backup job logs. The difference in time between your full and incremental jobs is not large, suggesting that the incremental jobs are backing up a large amount of data. What backup protocol are you using ?
