[Windows Mobile Development and Hacking General] dragonfire613:
Not able to get very far in this at all sorry, and looks like the OP or anyone with knowledge to help me may be no longer following this thread, but I followed instructions exactly. Have a Toshiba 8GB MicroSD card that reads only as 4GB in my HTC / AT&T 8525 on Windows Mobile 5.0, running Win XP Pro SP3 on PC...and even with the 4GB detected on the phone, it only works maybe 5-10 minutes before the phone stops reading it altogether and locks up requiring a soft reset. install WMStorage on my Phone just fine, run & activate it fine. But when I then plug my phone into PC it pops up a New Hardware Found "Mobile Device" immediately followed by "USB Mass Storage" and then immediately followed by a "Your Hardware Did not Install Correctly"... in My Computer "Mobile Device" Still shows up separate from the Hard Drives & Other (CD/DVD, Mounted, etc.) drives.

I have a hunch it has to do with the built-in card reader on my PC or the fact that ActiveSync runs in the background all the time (tried deactivating it in MSCONFIG & Rebooting but no change in behavior).

Anybody have any advice? And to those who say they have partitioned the card easily on a card reader in Windows... how did you do it? On my install, cards show up as "removable media" and no option to partition...

Going to try using command prompt to partition and see how that goes...

Yeah just no luck. Windows will not read this card as anything other than removable, and it never shows up as a drive that can be partitioned....

(Added later: )

Still no luck with getting windows to recognize the card when it is plugged into the phone. I completely uninstalled ActiveSync thinking that was perhaps the problem since it would still detect as "Mobile Device" when I plugged the phone into PC using miniUSB to USB cable. When I plug it in I still get the "Found New Hardware"... then "USB Storage Device"... then "An error occured activating your device" (not exact wording perhaps). When I reinstalled ActiveSync 4.5 I notice that it updates my USB drivers. Perhaps this is the issue. Does anyone know how to roll back to my original USB drivers before ActiveSync? Or offer any help whatsoever? Or even read this post anymore? Seems like this should be a simple process to do... put a partition on a storage device, but everything reads it as "Removable Storage" if at all, and never as a hard disk that can be partitioned. Running XP SP3 if I didn't mention earlier. Help?!?!

Giving up at this point. Found that there are several versions of WMStorage out there later than the one in the OP, so I downloaded the latest 1.9 and installed on phone, activated just fine. Rebooted phone, rebooted PC. Plugged in USB, same result. Recognized phone as mobile device, then USB storage as hardware that cannot connect error (code 10). Tried rebooting without ActiveSync on, same result. Then even went to Device Manager and auto-updated driver for the malfunctioning "USB Mass Storage Device" and the auto-update said it found a new driver and installed it, and then the malfunctioning USB Storage Device changed to a malfunctioning Bluetooth Device (Still error code 10). So I Unplugged everything and then removed the bluetooth device in device manager & rolled back driver for USB Mass Storage. I guess at this point I'll just wait until I do the WIndows Mobile 6 update in a few days (haven't done it yet because a replacement phone is on the way due to a warranty exchange) and see if it recognizes the new cards. FYI, the new 8GB MicroSD Class 4 Cards work just fine in Camera, PC). I also tried several different ways of reformatting the 8GB MicroSD card with FAT16/64K and always formatted as FAT32/32K anyway. No clue and appears this post is abandoned... not sure why I'm even going into all this detail.
