Flash Thumb Drive / SDcard no longer recognized by Win7
“The problem is that when I insert a Flash thumb drive or SD card, it is not recognized by the system, though the system’s response to attaching these thumb drive and sdcard varies.
Sometime I hear the usual tone that the system recognizes the disk, but I don’t get the “What do you want me to do?” prompt. After awhile, the corresponding icon for the drive will show up in the “Devices with Removable Storage” section of “My Computer” (or in the case of an SD card, the icon for the card reader will no longer be greyed out). However nothing happens when I dbl click on the icon. Other times, the system will state that the device needs to be formatted.
I have 3 USB 2 ports in which this occurs and I have tested all of them with an external HDD and it mounts correctly. I have tested the Flash Drives on other computers and they are formatted correctly. When I attach my camera via USB, SD card works fine.
