So, this has been going on for over a year now. When I plug in my camera, which has photos on it, the PC wants me to format the drive (ERROR MESSAGE IS: "You need to format the disk in Drive E: before you can use it. Do you want to format Drive E?") , so I am unable to view the photos from my camera on my PC. When I plug in the Garmin, to update the software, the PC does not recognize that it's plugged in. When I go to "My computer", it shows that I have these devices plugged in, but they do not work. I can play music CD's in my CD/DVD drive (by going to Windows Media Center), but nothing else, i.e., new software, or software for my camera. I used to be able to just put the CD or DVD in the drive and it would start up. Now, I put the CD or DVD in the drive, it starts to make a noise like it is being read, but then nothing happens. When I go to my computer, and double click on the D: drive, it says, "insert a disk into Drive D", and then it ejects the CD in the drive. My mouse will work, although I have had problems with it, too. I had a wired one which then quit working, then I used a wireless one. The wireless one quit working, so I plugged in the old wired one, and it started working again. Any advice? I have Windows Vista Home Premium. Anything else you need to know to help me, please let me know. I have searched a lot online for answers and tried many things which didn't help and finally decided to try getting help here. I'd like to be able to post photos on eBay again. Thanks for any help!
