So, I just had it happen to me again (all storage gone) while moving some apps to SD card. Read the details in Issue 4637 that state not more than 50 apps can be added to SD card. Solution seemed to be delete some apps using .android_secure folder but my .android_secure folder is empty??? Tried simply deleting some apps from the app drawer but this did not solve the issue. Please give a few more details on your suggested fix above by booting to WebOs and going into USB mode. Deleted a few apps from what folder, please? And why deleting from WebOS and not CM7 (although, CM7 says these apps aren't installed, maybe that's why?) Also, am I to understand that we can't add more than 50 apps to the SD card...forever?
Thank you!
Update: After uninstalling a few apps from the SD card using the app drawer and a reboot, my storage is back and apps are "installed" again and working. Still, if anyone has any further info on this problem, please post as 50 apps is very limited IMO. For now I'm going to move some smaller apps to phone storage.
