From http://www .storage.ibm.com/hardsoft/diskdrdl/micro/appguide. htm#hardware
"A minimum of 500 mA current must be supplied to the IBM 340 MB or 170 MB microdrive through the CF slot with a minimum duration of 300 ms from a 3.3V or 5.5V power supply."

from the TRG pro devkit:
"Continuous currents up to 250mA (500mA peak) can be delivered to a CF+ device"

Can someone confirm this? Sounds like this thing will eat up power like mad...
