I seem to have hit another problem with my Helios64. It seems that overnight, HDs 4 and 5 disappeared and no longer seem to be powered.

 

I've disconnected all the other drives and tried it with just 4, and it seems to be a power problem as the drive activity light seems to light up for a short while, but not at full prightness. Also I note that SATA 4 and 5 are on a separate power line to the other 3.

 

Anyone seen this before? Is it fixable?

Hello,

I have the same problem with the SATA 3, 4 and 5.
They where failing very often and the RAID 6 was falling and I had to rebuild. But on the last days they don't even powerup.
I've tried repluging everything with no success.

I'm using 4 new seagate's Red 4TB with Raid6 ext4 and one M2 SSD WD Blue.
