microsd is not "responding" - how can I verify it is working (without a second micro SDHC card?)

If I recall correctly, when I first bought my laptop, and moved my microsd from a device that died to my new acer I could see the files, photos, etc. on the card.

When it changed I cannot say - only have had a bios update to improve performance (so it says), but when I look (for the first time) in acer care center, mysystem, device drivers, the chipset driver entry has neither a provider, nor a version number.

I trusted the ACER popup to install a real driver - and am still hoping that it did.

Back to Acer Care Center - under updates: no critical, no general, driver update shows chipset driver, more and update button - update does nothing, and more just says chipset driver - provider and version are blank.

Update History: Update BIOS to improve performance, 3MB, Version 1.10, andd the date I installed it.

I am hoping for something simple to wake it all back up, even it it means I need to reinstall OLD firmware.

I have tried reviewing via Device Manager - but cannot find anything that is not "enabled, work properly".

Suggestions welcome!

p.s. SW5-012 is the device.

With the system booted, remove the SD card, wait a bit and reinstall. That should force the system to rediscover it.

May also be able to check in an Android smart phone.

is a roolback from w10 to w8.1, and the related reboots - with it installed out long enough (read, i was not sure if the problem was caused by w10. in any case, when i did the update, now undone, the microsd was not accepted as extra storage. i had to use an external disk via usb.
