For almost the last year I have been on and off trying out a 2.2 Gig 
microdrive working with my jornada 720.

Before all the details are they are kernal tweaks that I can use to get this 
drive to work, such as options for the kernel config to dumb down the ATA 
mode or whatever.

Initially with 1.6.X the drive was barely recognized, the kernal would report 
finding it and then would lose it.

Now with NetBSD 2.0 with sys/arch/hpcarm/hpcarm/softintr.c rev. 1.9 I can boot  
from the drive use it for a while (10mins) before errors pile up and the unit 
freezes, giving I/O errors.
 The Drive performs flawlessly under Win CE I have filled it full of music and 
listen to it continuously.

Details, in the following errors the system has booted from a 32Meg flash CF.  
I have tried with the drive in the CF slot with the same results. (take the 
outside panel off  the flip down tray and your can fit a CFII )
