Computer Guru's, Does my external Hard Drive go to sleep if its still blinking?

If backed up, then no worries. I've had hundreds of 7200rpm drives running 24/7 for over 5 years with maybe 3 failures. Also scores of 15k SCSI on 24/7 with 3 failures.

noromance, thanks,

When I touch  the hard drive after the Lumin has been off for hours, the hard drive doesn't seem to be warm.

Do you think the HD internal disc keeps on spinning?

The hard disk "enclosure" LED will usually stay on or blink to indicate it is receiving power although the drive itself may have been spun down. You might want to check the enclosure manual to see if they have anything listed for the LED as a status indicator.

It sounds like you're worried about the drives spinning down and then locking up or crashing when they spin up, if this happens often and the drive starts to age (or is relatively new and untested). I'd definitely recommend having a backup of the music. Using a NAS with RAID is another option that would be statistically safer. You could also consider using SSD drives.

Can you "feel" the vibrations between when you know it’s running and when you think it’s off?
You could use a makeshift stethoscope from tubing... or get one of these or even cheaper.

I should add the breakdown maxim: It's not if, it's when.
