When testing failed SD Cards (not there are many components to check) what voltages in general do they use? I currently have a 4GB Kingston SDHC Card.

3.3v, maybe 1.8v depending on the device.

Well ,
When you apply a multimeter to a sd card testing for shorts between ground and VCC its generally 3 volts or 1.5 volts from multimeter ,but they operate at 3.3 volts imho .Starting to work on more nand flash memories now ddrecovery but late then you started

I thought Tim was referring to the internals, not the interface. Internally, some use 1.8v Vcc or VccQ, mostly 3.3v
Obviously if it's short to ground you're SOL with the NAND.
