Emax

Has anyone had the same experience...
I eventually managed to find the right CF cards for both my Emax II's (1Gb, Calumet branded). After a few months, I managed to get hold of another ACARD and IDE-CF adaptor. I 'thought' it would be easy enough to install a second CF card (with a different SCSI ID number) in one of the Emax II's. Everything seemed fine - SCSI cable, Molex cables, jumper settings checked on both ACARDs, Master and Slave jumpers set on the IDE-CF adaptors...
But on powering up, the PSU started clicking and I've managed to literally fry one of the CF cards (the primary / master boot card). I will now carefully check both the IDE-CF adaptor and ACARD on a PC, to check for any damage.
I can only think that a 12V and a 5V rail may have crossed over somewhere, but I couldn't see this when checking the cabling. 
Anyone had the same issue? or successfully ran with 2 separate ACARDs and CF's in one Emax II??

You probably overloaded the Emax power supply.
The Emax can support 1 drive.
But power wise I would not expect it to be able to support 2.
Then you have the potential for voltage fluctutations that could damage anything and everything.

But that is just my opinion.
I would have to perform some test with that specific equipment to provide conclusive analysis.

Thanks Ted. I've never had any problems with the power supply until now - and it seems to have been brought on by my second solid state drive. I was always under the impression that the CF card adaptors and ACARDs would draw much less power than a conventional hard disk drive!?! But this proves otherwise. Oh well, back to one CF card then :-(  Seems greedy, but I wanted the Emu library on one CF card and my own banks on a separate 'working' or 'scratch' CF card.
