Windows 7 - Contents of SD card not recognized

I am having a problem with memory cards (SD) contents being recognized on a Windows 7 Pro machine. I am using an internal card reader, and have virtually eliminated it being a hardware problem because a new replacement unit gives the same results.
The first time a card is placed in the reader after the computer is booted, the card is recognized but not the contents. In Windows Explorer, the card is designated "Removable Disk (H)". When I attempt to navigate to the contents, a window opens titled "Insert Disk", prompting that a disk be inserted into the drive.
I can correct this on subsequent card insertions by clicking on the "Safely Remove Hardware and Eject Media" icon in the system tray. When clicking on the specified card/device (only item showing) I am prompted that "Removable Dish (H)" is currently in use". There are no applications open including Windows Explorer. Of the choices given, (Cancel, Try Again and Continue) selecting Continue results in an indication that it is safe to remove the hardware.
When I remove the card and replace it, I don't get the expected Autoplay prompt, but when I open Windows Explorer the disk shows with the same drive designation, but this time with the volume showing instead of "Removable Disk". I can then navigate and find files and folders on the card.
Removing the card again and reinserting it using the same procedure the second time results in the Autoplay window opening and the contents of the card being recognized in explorer. At this point everything works as expected and will continue to until the computer is rebooted.
I would like to find a way to have the volume and contents of the card recognized and the auto play window open the first attempt after the computer is booted.

If you have all the data off of the card try formatting it with this. You will lose everything left on the card. Download is on the left.

SD Card Formatter

I had the same problem. Determined that it was an SD card error. Replaced card and all is well. Be careful during cold weather when handling your SD cards. Static electricity will ruin one.
