exfat and windows os

If you format a micro SD card in mobile device using eXfat option, you can not use the micro sd with some windows xp PC. So make sure you use FAT32 option to format, in case you want to access the sd card data in a PC.

Some advantages of exFAT over are:
Scalability to large disk sizes.
Theoretical file size limit of 16 Exabytes, limit lifted from 4 Gigabytes in FAT16.
Support for more than 1000 files in a single directory.
Free space allocation and delete performance improved due to introduction of a free space bitmap.
Support for access control lists.
Support for Transaction-Safe FAT File System.
Provision for OEM-definable parameters to customize the file system for specific device characteristics.

We can’t access exFAT formatted partition or removable devices in all Windows OSs excluding Windows Embedded CE 6.0, Windows Vista SP1 and Windows Server 2008. But don’t worry…I have found an solution for this prob. Now atleast you access exFAT formatted partition. I have tried on Windows XP SP3…and it works flawlessly. It may work on earlier version of Windows too.

How to-
1) Copy exfat.sys and uexfat.dll into %windir%\System32\Drivers and %windir%\System32 respectively.
2) Copy the Reg code, given below into Notepad and Save as exFAT.reg
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\exfat]“Description”=”exFAT File System Driver”“DisplayName”=”exFAT File System Driver”“ErrorControl”=dword:00000001“Group”=”Boot File System”“Start”=dword:00000002“Type”=dword:00000002
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\System\exfat]“EventMessageFile”=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,\00,6f,00,74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,\5c,00,49,00,6f,00,4c,00,6f,00,67,00,4d,00,73,00,67,00,2e,00,64,00,6c,00,6c,\00,00,00“TypesSupported”=dword:00000007

3) Double click on Reg File (exFAT.reg) to patch it.
4) Restart your PC to take effect.

cetk error --> "unable to load device side components"

when we are using cetk first time on a PC it may sometime throw an error message "unable to load device side components"

Steps for getting this error:
1. Connect the device to PC in Active sync
2. Open CETK application
3. Click on "Start Client"
4. keep proper connection settings.
5. Click on "connect"

Observe that sometime while connecting we get this error message

Cause for this error is CETK tries to locate the Device side components under your machine on "C:\Program Files\Common Files\Microsoft Shared\Windows CE Tools\Platman\target\wce600\armV4" whereas the PC has the folder "C:\Program Files\Common Files\Microsoft Shared\Windows CE Tools\Platman\target\wce600\armV4i" only.
Solution is to create a folder armV4 under the above directory path "C:\Program Files\Common Files\Microsoft Shared\Windows CE Tools\Platman\target\wce600\armV4" and copy all content from the armv4i folder.

enjoy testing...:)'
