Hi,

I recently upgraded my R730 with six new HGST Ultrastar C10K1800 HUC101830CSS200 300GB drives. BIOS detects them just fine and I'm able to build any typ of raid array to my choosing, and the disk performs as expected. However, I have two issues:

1. Both LED indicators are displaying a constant green light. Is this because they are not Dell HDD's and therefor for some strange reason can't detect activity?
   
   
2. Every two minutes or so all six drives read/seek extensively with a loud noise. It last about 3-4 seconds each time. This is regardless of raid/non-raid, one or all disk installed. It starts generally about ten minutes in after server is switched on.

 

The two Dell SAS HDD supplied with the server work normally; no issues with LED indicators nor strange read/seek noises.

I can live with no LED indication, but the read/seek patterns is really worrying me. Any suggestions to what this may be?

Regards

Andreas
