Question

Is there any tool to create a new partition on windows CE device?
Device has a NAND flash memory and initially there were two partitions. Using Storage manager in Control Panel I was able to delete one partition but when I want to create it again, I get an error message: “Unable to create partition”.

With the source code of Windows CE 6 you get the BootPart library source code. The location for the source is WINCE600\PUBLIC\COMMON\OAK\DRIVERS\ETHDBG\BOOTPART.

Inside Bootpart.cpp you can find the function BP_OpenPartition that opens/creates a new partition. It basically adds information to the MBR.

The above solution is a bit low level. Here is a way to do it through Win32 API (taken from here):

• Call OpenStore to get a handle to the store
• Dismount the store using DismountStore
• FindFirstPartition/FindNextPartition will iterate over existing partitions and DeletePartition will delete those that can be deleted.
• GetStoreInfo will get you the number of sectors available for creating a new partition ((STOREINFO.snBiggestPartCreatable)
• Use CreatePartition to create the partition.

All the pointers to the functions and more information about the storage manager can be found here: Storage Manager Reference

You can see that the links I provided indicate that the functions work on both Windows Mobile 6 and Windows CE 6. Non of the functions are new functionality so they should also work with Windows CE 5.
