Well, the LUN comment got me thinking so I edited HDToolbox to remove that line and now I can see the cards Most of the time.

Curious thing is sometimes units are read okay, but I'm still seeing a LOT of "Unexpected Status $4E/$20" errors.

Sometimes a card will be read and I try to partition it and things seem to be going okay.  Do the required reboot and nothing is found and it goes back to the $4E/$20 error.

I also tried several IBM Microdrives (340M, 512M and 1G sizes) with an IBM adapter and it seems to REALLY HATE those!  They error out almost all the time.  Thing is I remember using them on a GVP combo board before and they worked fine.

Heck, I got a Viking 512MB to get almost all the way through setting up.  Defined it, tweaked the settings to fit the drive when it couldn't read the C/H/S stuff.  Partitioned it, and was saving the info to the drive and then everything froze up!

Puzzling still.

Anymore suggestions?  I'm pondering reloading 3.1 on the Maxtor to see what that would do!
Puzzling.

the pcd-25b does not use luns. the jumpers must be right or u will have troubles.
take the screw off the bottom that holds the plate on and make sure there are terminating resistors in it.there is also additional jumpers under that plate. If no terminating resistors, then use a external terminator with it.

make sure the pcmcia adapter is 16bit and not 32bit card bus.
don't use oddball cf cards. go buy a sandisk 4gb or less and try it. forget microdrives.
