SD card stopped working in old reader while reader and card are OK
Windows 7 SP2 Intel desktop PC.
I have a weird 3½ slot internal USB card reader problem.
All SD and mSD cards (last with adapter) are recognized normally as storage devices except one Sandisk Extreme Pro 8GB micro SD, which worked normally until 2 weeks ago but still works normally with other external USB card reader.
With internal USB reader all SD cards used to be drive L: and still are L:, except this Sandisk Pro.
When this Sandisk mSd card is inserted nothing happens and looks like Windows considers it as nothing or something else but not a storage device.
Nor computer storage manager doesn't see it in internal card reader.
But when I use external card reader, this Sandisk SD card works normally and is given a letter S:.
It looks like some kind registry numerator of USB devices has listed this SD card ID as not storage device.
Any ideas how to troubleshoot?
