A Pocket pc live supporter has submitted an another intresting tutorial.

Introduction
Transcend and several other manufacturers make 4GB SD cards these days. They're great if you use your HTC device as MP3 player or Camera, as they offer enough space for thousands of songs and pictures.
My device, the HTC Universal, handles them just fine. However some applications, most notably the Camera application, don't like it.

Why some apps don't like it
The main problem here is the way in which they calculate the free space.
the processor is 32-bit, which means it can handle numbers ranging from 0 to 2^32. 4GB is exactly 2^32 bytes, so that shouldn't be the problem.
The problem is that applications sometimes handle the number as signed, which means that it differentiates between negative and positive numbers.
With signed numbers, the last bit is actually used as the sign (positive or negative), and the new range stretches from -2^31 (-2GB) to 2^31 (2GB).
Up to 2^31, the unsigned numbers and signed numbers are the same, but after that the last bit is set in unsigned numbers, which means that if treated as signed it will be seen as a negative number.
So if you have more than 2GB free, and the application mistreats the number of bytes free as being signed, the application actually thinks you have less than 0 bytes free

How to fix this?

• First, make a backup of your SD-card! the following procedure will erase it!
• Next, install WM5Storage. The latest version can be found here.
  Just copy the .cab file to your device, and execute it from the file explorer. Just make sure you install on the main memory, as the SD-card becomes inaccessible during the procedure
• Start WM5Storage. On my device, WM5Storage did not put anything in the start menu or the today screen, so I had to launch it through the file-explorer. You can find it at My Device\Program Files\WM5Storage\.
• Be sure to untick both "Read-Only" and "Removable Class". Optionally you can set it to light a LED on read/write, but that's not neccesarry for this procedure.
• Disconnect your device from your computer.
• Insert the SD-Card if you haven't done so already
• Hit "Activate" (bottom, right)
• Re-connect your device to your computer.
• From now on all steps are done from the PC
• Wait until windows has recognized all "new hardware", and you have new a new hard-drive listed in "My Computer".
• Open the control panel (Start -> Control Panel)
• Go to either Performance and Maintenance -> Administrative Tools (category view) or directly to Administrative Tools (Classic View)
• Double-Click Computer Management
• Go to Computer Management (Local) -> Storage -> Disk Management (might take a little while to find all drives)
• In the bottom view, find the disk that has your SD-card in it (You can find out by looking at the contents through "My Computer", or by seeing which disk is added once you plug in your WM device)
• Right click the partition (white block ), and choose for Delete Partition
• In the just created "Unallocated" space, right click, and choose for New Partition
• In the wizard:
• choose for a Primary Partition
• For size, enter 1024MB (or if there is no more remaining, just the remainder). Ofcourse you can also choose your own size
• Assign any drive-letter you want (or none if you only want it to be accessible on the WM Device).
• Format the partition as Filesystem FAT32, Allocation unit size Default, and pick any volume label you want (You will only see the volume label on the PC, on the WM Device it will just be "Storage Card X". Also tick "Perform a quick format"
• Wait until the bottom line in the new partition reads "Healthy" (wait for it to format basically )
• Create as much partitions as you'd like (just resume from right-clicking and picking New partition)
• You're done partitioning! If you want, you can fill the contents of the SD-Card now before you deactivate WM5Storage
• Disconnect the device from the computer
• Next few steps on the Device
• Click "Deactivate" (same place as "Activate" was before )
• Close WM5Storage
• You're all done! have fun with the multiple storage cards you have now :P

Help on 4GB Mini SD card partition John (205.157.244.xxx) 2007-03-20 23:08:18 Help Please... I partitioned the drive as the program as instructed and it only reads as a 1.89 GB miniSD card now. Is there a way for me to reformat to 4GB and start over? Is it possible to format the card from a card reader instead? Reply | Quote 0   0

Carty (59.97.65.xxx) 2009-03-15 07:05:48 Dear Jude, Power button is very important in PocketPC as you need to use it not just for turning on but to resume the device from resume state. However that is absolutely wrong that it costs the price of the mobile to replace it. Please use our forums/Expert's help section for more suggestions. Reply | Quote 0   0
