Omnia 2 doesn't recognize internal storage!

I rebooted my Omnia 2 and found that it didn't seem to recognize the internal storage card. The "My Storage" folder was missing and none of the apps installed there worked. They're still visible in the program list, but I get a popup-error when I click on them. When I opened the battery-cover I found a lot of dust, which is a common problem with the Omnia. Could the dust have "destroyed" the memory card? Also, if I tear apart my phone, would I be able to remove the memory card or is it locked to the phone?

Please help!
Thanks.

Thanks for the link.
I installed NueStorageManager like the instructions said, but I couldn't find the missing storage. I haven't done anything to my phone so I have no idea what could have cause this. I might have accidentally deleted "My Storage" in the file-manager. Is that even possible? Or there could have been an error when I removed the USB connection to my PC. While the phone is connected using mass storage the storage is not visible in the device. Perhaps the phone didn't recognize when I disconnected it, and it still think it's connected.

On the device, when looking in the USB Connection settings you can select "My Storage" from the list of storage cards. When I connect the phone to my PC the device status says "This device cannot start. (Code 10)". I uninstalled the device from the Device Manager, rebooted my phone and tried to reconnect. This time, it couldn't install the device!

If I try to reset My Storage it just says "My Storage unavailable". I did a hard-reset but that didn't help.
I guess I'm gonna have to live without my storage. Dang it.
