I had the identical story with my system about 6 months ago. The slave drive (which housed 3 years of data) now sits on my desk as a paperweight.
What happened in my case was that I didn't unplug the system from the wall - and static destroyed the PCB on the slave drive. Recovery will cost $600 to $1800 (this was 6 months ago). Another option is to cannabalize the PCB from another, identical drive and use it on the fried one.
In case this is not the same situation, you can try this free file recovery tool: http://www.pcinspector.de
? It's a very good program and has recovered other data for me.
Another nice recovery program is GetDataBack by http://www.runtime.org/
They offer a free program to see what you can recover (it also comes in 2 flavors - NTFS and FAT). If there is recoverable data - it'll cost you $80 US for either the NTFS or the FAT (they've got a bundle of both for $120). I find it easier to use than PCInspector, that's why I purchased it.
