What to do with 199MB unmounted drive in Win7

July 30, 2011 at 00:46:52
Specs: Windows 7 Professional SP1, Intel Atom N470 @1.83GHz / 1.00GB RAM
After successfully upgrading my netbook's OS Windows 7 SP1 Starter Edition to Windows 7 Professional utilizing Microsoft's Anytime Upgrade feature via internet, opened my 3rd party disk utility to defrag my system only to find a 4th drive, an "unmounted drive" with no drive letter. My system is working fine, even installed the latest updates via "Windows Update" feature. What would be the recommended action regarding this matter? Any advice would be greatly appreciated. Thanks in advance.

Right-click 'My Computer' and choose 'manage', then click on 'disk management'. Look down the list for your errant partition & see how large it is and what 'state' it is. If it's only a few Mb (I suspect it may be 8Mb) then just ignore it. If it's a substantial size then double click it and go through the wizard to assign it a letter.

How big is it? ~100MB and it's the hidden partition that Windows 7 uses, ~10GB and it's a recovery partition.

In either case I would leave well alone - if it ain't broke don't fix it.

Sounds like the hidden Windows 7 partition. Leave it alone - who needs an extra 200 MB. I'd also remove the drive assignment from the Recovery Partiton (and probably the HP Tools one too). You don't want to see them in day to day use, and you don't want to risk messing them up.

You may be sorry if you mess with that.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

I would assume that HP loads the disk image to the hard drive from their master and due to differences in individual drives and different brand drives they use, they select a size to image that will safely fit on any drive they may use of that nominal size. As stated above, it would be safest to leave it alone. If it was definitely unallocated and adjacent to your C drive you can expand C to include the space, but it is probably not adjacent to it and it may give you trouble if you ever need to use the factory restore feature. You will not really gain enough to make it worth the risks so just leave it alone and ignore it.

You have to be a little bit crazy to keep you from going insane.
