How I determine what drive is "ata1.00" on my array.

 

I noticed this is my syslog.

Search the syslog for "ata1.00". You should find a line that shows its serial number. Search the syslog for that serial number. You should find what disk that serial number is assigned to.

 

You can also look in your diagnostics in system/vars.txt for the serial number to see what disk it is assigned to.

 

There may be other ways but those are what I have found.

 

Looks like it is cache according to your diagnostics.

You can also click on the blue disk icon of each disk on the Main page. It will show the log entries belonging to the disk, including the ata reference.

I figured there was an easier way these days. Probably added some time since I first did it the hard way by searching the syslog. No doubt other "easter eggs" I haven't discovered in the webUI.
