I just completed doing a RAID 1 conversion for the internal drive on my two tuner Moxi with a Cool Drives SiL57x4 based two drive external enclosure. My internal drive is just over two years old, a Seagate Pipeline 500gb, same model as original which had failed. I had 3 spontaneous restarts in one week. Including one restart that took three “checking hard drive” cycles to complete. I was predicting an eminent failure.
I use a Cool Drives two drive RAID enclosure with 2tb drives for the Moxi external drive. I had a second Cool Drives enclosure from my media center, which was replaced with a 4 drive RAID 5 system. I ordered two WD Black 500 gb drives from Newegg ($64 each on sale last week).
I placed the old Seagate in the array, set the config switches to RAID 1, the manufacturer calls it SAFE mode, then cycled on power and pressed “set up” on the enclosure. This tells the RAID box to configure a RAID 1 array. The key feature here is that this does not erase the current data on the drive. Then I hot plugged a new 500 gb WD drive in the second slot. Within about 3 min the enclosure started a rebuild of the array by copying the old Seagate to the new WD. The rebuild took about 5 hours. This was all standalone, with the array disconnected from the Moxi.
When this completed I connected the array to the Moxi mother board with a SATA to eSATA cable. I currently have the Moxi cover adrift to route the cable out of the Moxi. Then powered on the Moxi. It completed the boot and was running fine with all saved recording lists and programs that were originally on the internal drive.
To be real bold, I then hot pulled the old Seagate out of the array, plugged in the second new WD drive and a rebuild started again. The TV channel I was watching didn’t even blink. The rebuild onto the second new drive took about 6.5 hours, due to the disk writes taking place as the Moxi was continuously running during the rebuild.
** Feb 22 update: After a week of operation I have found that when two recordings are in process, one on the external drive and one on the internal, and a prerecorded show is being watched from the internal, and a rewind/backspace is performed, the Moxi will occasionally hang (stopping both recordings and the playback) for 10 or more seconds. Everything continues after the hang. This is fairly easy to reproduce.
If the playback is on the external drive there is no hang. I have not been able to cause all functions to go to the internal drive to test that. I assume it would show the same issue.
This is also with a 30" SATA to eSATA cable. I am going to try a shorter cable.Edited by Robert Duncan - 2/25/13 at 7:59am
