So I downloaded the latest OTA update last night, and it installed just fine (phone worked fine, etc). I went to bed later last night, then when I woke up this morning, I got a "SD Card blank or has unsupported file system" message! The first message I got was actually something a bit different. Unfortunately, I can't remember exactly what it was, but I clicked on the notification and it tried to do something with the SD Card (probably remount it or something), and ever since I've been getting the "SD Card blank or has unsupported file system" thing. Now my only option given when I click on this notification is to format the SD Card. This is really annoying; I don't want to format my card and lose all the data! Are there any 'fixes' for this? I noticed a lot of people had this problem with the original HTC Desire. P.S. I haven't rooted my phone or anything like that, so that wouldn't be an issue. Edit: I tried all the usual stuff such as rebooting, taking the battery out, reseating the mem card, etc, numerous times to no avail. I got so tired of it that I just tried the format option, but it won't even let me format it! It just does nothing after I click it.
