Win10 Disk Management and Explorer disk display problem

[WorriedNoodle]

Hi Guys,

Not sure if anyone can help, but my Win10 seems to display my hard disc and partitions erroneously?

I have 2 discs with the 2nd disc partitioned as E: and M: drives.

From the attached there are two problems?

1. Why does file explorer show TWO additional partitions (D: & I:) that don't exist? Indeed when I click on either these two drives Not available box shows up.

2. Why does disc management show the M: partition as TWO blocks when I might have expected only ONE block?

Appreciate any leads on this guys.

Can you boot up in Safe Mode and see if you get the same results?

Hi Chicog,

Yes, I just figured out how to reboot in Safe Mode (using msconfig run command - not sure if there's another way?) with Win10 and problem #1 went away in safe mode, then reboot to normal and problem #1 gone.

Now I still have problem #2 with disk manager showing TWO M drives boxes of different sizes whereas table above it lists one drive as it should be. I wonder why there are two boxes in the graphic display below?

[Chicog]

Strange. Have you tried changing the drive letter of one?

Dynamic disks can do weird things like that. If you dare, you could convert the disk back to basic.

But since it's only 70GB I would be inclined to move the data somewhere then delete and recreate the dodgy partition.

I think it's called volume slice which has something to do with not having enough unallocated space to make the volume contiguous.

^^^ Yup. Probably a non-contiguous space so it was split into two dynamic partitions.

I read something about a maximum of four partitions per volume, or was that four volumes per partition??? I would copy the stuff on the 14Gb M drive somewhere, delete that partition, add it to the bigger M drive, then restore all the copied stuff into the expanded M. As above, D looks dodgy - hope you have back-ups coz it's gotta go

[WorriedNoodle]

Ok guys, thanks for all the helpful advice. I learned something about dynamic disks and volume slice which sounds plausible.

If I just changed drive letter it made no difference and the newly named drive still showed as two blocks in the graphic, so I deleted the volume and remade it and now I have one continuous block of M (Entertainment) drive shown in graphic.

Really appreciated the tips guys, thanks.
