SD Card won't mount correctly in WinXP

---

Hi all, i do have big problem with my 4GB SD Card in Vodafone 845 (Androind 2.1) which won't mount correctly in WinXP SP3. New drive letter is assigned to SD Card, but when i try to access this new drive i always get message "Drive not found!". Approx. 1 week ago this procedure was working fine, and i was able to access new drive without any problems, but now this is not working for unknown reason. I tried to remove and reinsert SD Card, but it didn't help. SD Card is 100% fine, i can access data on it through phone itself - wallpapers, music etc. I thought that maybe USB cable is damaged, but it's not. I can access all data which are located in phone memory without any problem through this cable in Windows. Then i thought PC Suite app which was provided with this phone became corrupt so i reinstalled this app including phone drivers, but this didn't help. I tried to search for newer drivers for this phone, but i didn't find any. In device managers all devices are and were correctly installed - no unknown devices asking for drivers. So then i decided to do fresh install of Windows XP with hope that this will solve problem, but situation is same and it didn't help at all. I tried to install "automount" app from market, but it didn't help at all. I'm playing with these for long hours now, but still no working solutions. Can somebody help me to solve this issue?

The only thing I see is that you have tried everything BUT you have not tried formatting the card yet. Yes I know you are going to lose everything on it but that is the price we pay some of the time. Format the card and if it still doesn't work, let us know.

Thanks for advice!
Sorry for late reply, i was lying in the bed with flu. I reformatted SDCard and flashed new custom Mr.Edition 1.8 ROM. It's working fine now, i'm able to mount sdcard properly in Window XP now. Seems there was something wrong with SDCard, like if some installed app amended something in SDCard parameters, so WinXP was not able to recognize and mount it. Do you think is it possible?
