Hi I'm usin htc wildfire s. Every single time i update music, videos, tones, take any photos n most importantly install any apps in my device, after few days they're all getting corrupted. For few days they seem ok, but all on a sudden either they get lost or stop working. N when i connect the device to my pc or explore it with a file manager i'm finding them in the 'lost directory' as some unknown file format. Wanna mention that to save space of the device like most people i prefer to keep all my data including the apps in the sd card. So i thought at first it must have been a problem of the sd card. So i changed to newer one. But still the problem remains the same. It's really buggin me off. I tried antivirus, even updated the software a couple o' times but nothings workin out. 'll be immensely grateful if any1 can get me a real solution.
