Hello!  Occasionally, when I seem to least expect it there is an additional "drive" listed in the above location of my HP Pentium Windows 8 laptop.  So, there is my C drive, my Recovery (D) drive and my optical (E) drive.  But sometimes there is another drive that's not mine and doesn't appear to be in any way connected to Windows Update b/c there ARE no pending updates I have initiated or downloaded and it can appear for no reason.  It is always 256MB and generally has 156MB of that used.  I can not browse it b/c even though I am logged in as admin, the drive is locked.  I can not format it to wipe it (same reason) and the only way I can get rid of it is to reboot--sometimes it comes back, when I am not watching--or using CCLeaner's DRIVEWIPE utility which when I wipe that unknown drive, I get the blue screen with a message telling me something went wrong, an unhappy face :-( and I am told to wait while "files are updated" (and a percentage ticker as the "files" get updated). 


I do NOT wait--I just long-press the power button which shuts down the computer.  Then I restart and it starts like normal. 


(In the past when I DID wait, it took forever to "Update" and when it finally rebooted, more "Updating" would occur).


I don't do torrents, don't visit questionable sites, don't open attachments and in a word, have a secure environment.  I have used command prompt to block all automatic wireless connections except my own.  I know there's hackers out there and some of them are people who think they're serving America by embedding surveillance firmware/software and this is what I think is happening b/c I am a free speech activist trying to have the NSA's unconstitutional surveillance activities defunded.


The next time this appears I would like to use a more aggressive mode to query the provenance of this unknown drive (which I think is some kind of illicit partition) but don't know how, since it has restricted access.  Can anyone help me?  I can be patient as I await a reply and just FYI, I have donated to the worthy cause advertised on the welcome banner of this site.

There are at least 5 partitions/drives/volumes on W8/10 systems with only one physical hard drive installed.

Most of them don't have drive letters assigned, so you can't easily see them.

I suspect that you are seeing one of these partitions.


If that is the case, DO NOT mess with it - as doing so may render your system unbootable!
If you think it's from an infection, I'd suggest posting over in the Am I Infected forum:  http://www.bleepingcomputer.com/forums/f/103/am-i-infected-what-do-i-do/
Please read the pinned topics at the top of the forum for instructions on how to post there.

If you do decide to mess with it, make sure that you have backed all of your data up, and that you have recovery media ready in case the system won't boot (and we can't fix the boot problem here).


For starters, have a look at (run) diskmgmt.msc and take a screen shot for us to have a look at.

My system (a Lenovo with W10) has 6 partitions, only 2 of which have drive letters (C: and D: )
