I've have experienced this exact problem on a areca controller.
I always run a full surface scan to check for bad sectors before adding a drive to an array but there's still risk involved.
During an expansion the new drive failed. Areca Support helped me to force-resume the migration proces...
Reading this I understand you did not enable TLER on your 8 current drives? I'm supprised, aren't you experiencing problems like disks falling of your raidset?
I own a 24-port areca controller and back in the day when I did not enable TLER on my WD20EADS drives they were dropping out of the...
What a shame. Got 4 new wd20eads drives back from RMA.
Model 00W4B0 production date july 2010. Unable to change/view TLER :(
On my other 24 drives (00S2B0 / 00R6B0 / 32S2B0) I was able to enable TLER.
Started replacing the 1.5 with 2 TB's
Currently:
1x 1.5TB Barracuda 11 as buffer
8x 1.5TB Barracuda 11 in raid 5
8x 2TB Caviar Greens in raid 5
29.5TB raw space in a Lian-Li PC-A77. I bet that puts me somewhere on the "Most Storage in One Chassis" list :)
Thanks, the stacker is (was) a great case to start with. and yes total raw space is 36TB, 30TB formatted.
I'm looking for new ideas to build a high capacity "silent" setup, so if anyone has some.... Storage is addictive :D
I just had to give this case a try with SLI. Even without the 2nd videocard the system gets to hot with the sidepanel closed. It now runs with 1 card and without the sidepanel.
The heat of the psu is another problem. Time for some modding I guess. Without additional holes you can't get 8800GTX...
Little update
Added 6 more disks, total capacity 12,2TB formatted. Currently 20 disks connected to an Areca 1280ML with 2GB cache. Array is configured as raid 6. Upgraded LAN to 2Gbit.
Also added fan controllers to slow down those noisy 5000 RPM fans (not shown on pictures)
nice thread :) impressive setups
Currently in the middle of a little upgrade
Old system
Disks: 16x Barracuda 10 320GB, Areca 1160, Raid 6

New system, still work in progress..
