I had to use this method to resurrect my Microtrack II today, after I bought a brand new SanDisk Extreme 16 GB Compact Flash Card.
I put the new card into the Microtrack when it was turned off and unpowered from AC. The screen remained blank when I pressed the Power button. Switching back to my old Lexar 4 GB CF card, it was still dead. Only when I unplugged the Microtrack from the AC adaptor AND held the Power Button/Delete Button for 10 seconds WITH the Lexar card in it, would it come back to life.
It definitely does not like the SanDisk Extreme card, even though (as has been stated elsewhere in this forum) it is supposed to have been tested with 16 GB cards. I can get it to work with the Lexar card, but as it is a slower card (80x or 12 MB/sec) it will sometimes stop recording WAV files at 96 kHz. SR. It seems to work okay at 44.1, but I bought the faster card to enable me to work at higher sample rates - a $200 mistake! (The SanDisk Extreme Card is one of their newer series - 60 MB/s or 400x).
It would appear, more than ever, that issues with CF cards can cause all manner of problems with the Microtrack recorder.
