Highpoint RAID 640L Mountain Lion

[Chewiee]

I've built a hackintosh running Mountain Lion Server and installed a HighPoint RAID 640L card in it.

 

I've also added 4 x 4TB ST4000DM000 hard drives.

 

All had been running fine for about a year, but now I've got RAID errors happening:

 

1. B       0       W       08/12/15 08:56:25       Array 'RAID_5_0' rebuilding failed.
2. B       0       I       08/12/15 10:54:45       Array 'RAID_5_0' rebuilding started.
3. B       0       E       08/12/15 18:50:05       Disk 'ST4000DM000-1F2168-Z301RJK9' at Controller1-Channel3 failed.
4. B       0       W       08/12/15 18:50:05       Array 'RAID_5_0' rebuilding failed.

Obviously there is a lot of data on the drives and ideally I should just pull that stuff off now, but what I am concerned about is if this is just a false positive, because I've scanned the drives for SMART errors on another machine and it's not found anything wrong. Could this be a false warning?

 

At this point I'd appreciate some advice - in the mean time I'll be pulling data off of it like there's no tomorrow

So I have a 644l on my Hack with Yosemite. In the beginning I used regular desktop class drives and had troubles with my raid 5 array failing but when i switched to ST3000VN000 drives i havent had any problems since.
