Windows 7: Win 7 not recognizing USB data cards

Thanks. I found your thread Computer not Reading Mass Storage Devices and followed it exactly but it didn't work. Something is severely screwy in Win 7 because I did get it to work, sort of... I had removed the SD card and put it into a card reader & then plugged it into the USB & copied everything in the disk to a folder.

I then went to the disk management and changed the drive letter back (to G) and Win 7 was seeing the card as "raw data" with 1.87GB on it. When I made the switch a window popped up saying it had needed to be formatted to be used so I told windows to format it & it did in FAT 32. Lo & behold what appeared in my computer showed the drive as it should. I transferred the archived contents back to the card while it was in the phone and all was running perfectly.

Untill I shut off the mass storage within the phone so it could be used in the phone. & as expected it just showed the icon as a removable drive. I then switched back to the the mass storage setting so the computer & SD card could connect like they just had & nope... back to step one, no change in the icon except the end turned black as before when I went to the mass storage mode.

So windows XP has no issue with this, others running win 7 can do it but I can't. For windows to see it and then permanently stop seeing it, I'm simply dumbfounded.

I'll keep following this thread and maybe someone will have an idea what's going on but for now I'll just have to remove the card and insert it in a reader & then insert that in the USB port. I hate to do that because there's always a chance of a static discharge affecting the SD card but I can't see any other choice. Most inconvenient too.


Thanks all for trying.
