Monthly Drive Health Tests - Interpretation?

Recommended Posts

Each month, my Xpenology box sends me an email laying out hard drive health. There is one attribute that I am unsure of:

 

Drive Reconnect Count <----

Bad Sector Count

Disk Re-Identification Count

 

What exactly does a drive reconnect count indicate?

This is generally when the drive loses power and has to spin up again and reconnect. It can be due to a bad SATA/Power connection physically or it could be the board on the hard drive failing. I've seen other users who have had this issue and re-seating the cables fixed most users' reconnect issues...the rest had to replace their drives.

AH, I see, thank you! It just seemed odd how the periodicity of this error is so consistent! On my 411j, it was literally 1 disk always having 1 reconnect, every single month. It was so normal an occurence that I thought it was normal for disk 1 to behave this way! I will keep an eye on the disk and see how it goes. Thank you.

I wonder if these might be historical counts read from the drive itself rather than periodic counts. Some of my drives show the same thing for disconnects every month. I just assumed they were historical.
