Windows 10: What is local disk Z?

I see drive C and drive D, but don't know what local disk Z is . It's 256 mb in size, and about half full. I can't open it to see what's on there since I get a message, "permission denied." It's been there for a long time, but I'm just now getting curious.

:)

 

what is a local disk drive ands its difference between a local c drive?

Without context, the question is difficult to answer properly.



From where are you getting the terms?



A "Local Disk" is just that - local to the machine in question (connected, not via network.)

"Local C" would be the "Local Disk" with the "C:\" letter associated with it.

a sincere question-

 

I've seen this also, I think you'll find it's a partition of the main "C drive" that shouldn't show. A restart usually gets rid of it for me.
Hope this helps.

 

I believe you're right, except in my case restarting doesn't change anything. A little more investigating seems to confirm it what you said. Thanks.

 

{by me, from a related thread} Do not delete it, it's necessary for the computer to start. I have hidden system partitions appear as a Z drive too, usually after doing a virtual drive mount. Here's how to remove the letter from the drive to keep it from appearing under This PC (see screenshot of command prompts) window) -

Win+X/Command Prompt (Admin) {hit enter after each following command, observing spaces and letting each command finish}
diskpart
list volume
select volume # {whichever # is assigned to Z, example is 4, as if that appeared next to Z; eg- 0 to remove E)
remove letter=Z
list volume {not shown, but run to verify letter was removed}

 

Thanks. Looks easy enough.

 

I have just seen this local Z disc in my comp. for last few days.
I've scanned it by Malwarebytes.
It found 4 threats in Heuristic scan.
Log file below:

Restart.

And then local Z disc disappears.

^ It is more likely that the HP Support Assistant in your HP Pavilion is creating the Z drive. See Mysterious drive Z: appears!

 

At that size, it's clearly a system file. Tampering with it could make your Windows unbootable.


Edit:

Ooops, sorry. Old thread. Someone replied a few minutes before I did. I thought it's new. Haha...

 

Drive Z comes and goes on Gayle's HP laptop. Shows up some time after one of the major updates, hangs around a while and then goes away. All on it's own.

 

"Drive Z comes and goes on Gayle's HP laptop."

I have an HP too but have not seen it in quite a while, even after Creators Update. I suspect it has to do with a virtual image mounting but rather than diagnose where it came from, although I did uninstall HP Support Asst, just remove the drive letter using my method in Post 4 and be done with it.

 

The laptop sees limited use, so for the time being I'm going to just leave it and see what happens. If it doesn't go away on it's own, then you post will take care of it for me.

 

Consider the fix as a tornado shelter. You may never need it but it's good to know where to look. *chuckle
