SNAP 4100 Dead mobo

hiljak · 09-12-2007, 06:49 PM

Hello,

I am trying to help a friend out with a dead SNAP 4100. The unit will not power on at all, however, the power supply will start via jumping of the green wire, so I think its a bad mobo.

All the drives spin up and I plan to take sector for sector images of the drives with a READ-ONLY USB bridge using R-Studio. Does anyone know the offset of SNAP volumes so I can try to logically rebuild the RAID 5 from images using r-studio? Thanks.

Sorry can't help you there. The Snap OS is not a standard file structure. It's a highly modified XFS running on a modified BSD OS.

The 4100's were very prone to overheating when one of the fans would quit, especially on the little Intel processor. I've modified all of mine by moving the fan header over to an empty one on the right side of the systemboard (looking from front). Seemed like the temp-detect circuit wouldn't always kick the fan on, so moving it to the other header that has voltage to it all the time kept things cooler.

Just something to consider if you replace the system board.
