I've got the original Droid, with 16GB SD card (15.7 GB usable). According to ASTRO (file manager), I've got 14.3 GB available.
Yesterday, I got notices to update several apps; I believe all of them are put in by Google, and I can't deleter them: Facebook, Twitter, CarHome. I started to update them, but they wouldn't complete the download; a message popped up saying I didn't have sufficient storage available.
How can this be, with 14.3 GB on the SD card unused? I don't really have many apps, other than those that come with Android, so I'm astonished that I have no space available. I read somewhere that Facebook, which I do not use, can fill up space even when not in use. Could this be the problem? If so, what can I do about it?
