MOST IMPORTANT is to format your actual SD card and future SDHC card with fat32 ! (backup data before)
DONT NEED TO FORMAT IF YOUR CARD IS ALREADY FORMATED WITH THIS FILE FORMAT.
You can then use any fat32 card you want after SDHC upgrade.
WM5torage 1.78b is working fine but slow for me after SDHC upgrade. Tell us if it run for you too.
Artemis running WM5 could be flashed too, with Certification .cab (.xml inside). I will post a link as soon as possible.
ANSWER!! Yes WM5torage is very slow, as it is not working as usual. Don't know if the creator of this program gonna upgrade it for SDHC use. This software is not so important for the use of your SDHC Card, that was just to say that it could work (very slow) with new SDHC drivers.
[WARNING] There was some problems after this install. Tell me if you got problems using this .cab --> SDHC_Artemis_back2original.cab are the original OMAP850.dll, SDBus.dll, SDMemory.dll for Artemis, so you can load it at any time to go back to your original settings without SDHC support.
[WARNING] [COLOR="Red"] there is a problem if you plan to flash with SDHC card inserted on your device. With USB wire too. Remove your SDHC card before flashing or hard resetting your device.
