What on earth might be this Local Drive (Z:) USB 151 MB free/256 MB, appearing on a 2yrs old Windows 10 laptop? And, how to get into it for checking and trying to delete?

When trying to open it to see it's content -> Access denied from you (w/admin rights!)  -> Check Security Tab, but, on the Properties there is no Security Tab at all, like neither with other USB's.

On Device manager/Disk drives there is found
Generic Flash Disk USB Device
Device USBSTOR\Disk&Ven_Generic&Prod_Flash_Disk&Rev_8.07\94C8E0E9&0
with event date 29.9.2016

and, on Event viewer/System there were found notings
29.9.2016  13:43:59  Kernel-PnP  w/Event codes 400 410 440

When checking all this, after a restart, on the laptop there were no external connected USB or SD devices. And, quite sure, on the laptop there has never been inserted any 256MB USB stick ...

Thanks in advance for some help on this weird appearance.

Some Printers have card readers which can show up on the PC's attached to them. Or if you have a smart phone you might have bluetooth on, and the PC is connecting to it that way, which could also show the phone's SD card.

OK, thanks rindi for your hint.

Quite sure there has not been any Bluetooth connection, neither any printer at all connected, so, still no answer got for it.

But, most interesting would have been to know how to get the device opened and deleted.

Anyway, this my client just told it has now been vanishing, which is very miraculous ... let's see if it re-appears.

Now I close this question giving points anyway for a good hint.
