I started upgrading four 500GB HD to four 1TB HD last Monday.
Followed the instruction provided by many existing topic - swap one HD at a time and wait until it is fully sync and proceed with next HD.
I started from drive 4 and work my way toward drive 1. After drive 2, I did the same, pull out drive 1, NV+ shows drive failed, put in new drive, NV+ shows drive added. then I went to sleep.
Next morning (about 7 hours later) the system is OFF (I never had this with previous 3 HD), so I power it back on. I got the following message:
Checking FS: 1%
From RAIDar, it was showing resyncing 1% 2 hours and 13minutes, so I went out and got home around 4pm (7 hours later), no progress was made, still at 1%. I did several power cycle (I know I shouldn't
I pulled out drive 1 and ran Western Digital test (both quick and extended tests), but result PASSED.
Then I put drive 1 back in the NV+ and I still got the same message, so I tried upgrade firmware to 4.1.8 using USB and afterward I am still seeing 1% from the front LED on NV+
I am now backing up all the content to my local PC and thinking maybe I should wipe all four HDs and start from new.
I would like some suggestion/comment for the following:
- do a fully backup (will take several hours, I have about 400GB of data)
- run western digital test tool on ALL 4 hard drive
- reformat the HD on PC (????)
- put all drives back in NV+ and setup as new device
Any comments/suggestions are appreciated.
