So what happens if you right click disk2 and just assign a drive letter right there?

You could delete the system reserved partition.

Open regedit and rename mounteddevices to mounteddevicesold .

Then reboot.

Better have decent external boot media in case you mess something up.

haha, I took that screen shot right after I rebooted due to some new updates. I had totally forgot to do that before posting the screen shot.

Please see attach- when I assign it the drive letter (H:), it requires me to this every time I reboot in order for the drive to be accessed.

I thought you can't delete that partition- it drives me nuts. I could have sworn I looked into doing this before but that answer was no. Is it safe to delete?

What is considered to be decent external boot media? I have a spare laptop, Win7 installation disk, thumb drives, etc.

Yes. it should be fine.

If you have win 7 install disc - the system recovery options and access to command prompt are on there.

Alright I renamed mounteddevices to mounteddevicesold and I still get the following (see screen shots)

I still had to mount the drive after a restart

I'm also not having luck deleting the system reserve partition. I went back and read through it and it seems that its not just an easy "right-click > delete" option.

Anyone else able to shed some light onto this?

How are you attempting to do this? What error or result are you getting? Screenshot?


You should be able to delete it with a right-click on it from that DISKMGMT.MSC state. You should see "delete volume" on the context menu.

From your screenshot it's just a primary partition, no longer the "active" partition. So it should appear as deletable using DISKMGMT I would have thought.

You can always use Partition Wizard, free home edition, as well. For this task (which should have also been doable through DISKMGMT while Windows is running) you should be able to also use the installed version of PW itself while Windows is running. But if you want to be "safe" you can also do it while booted from the standalone PW boot CD.

I deleted the volume and now I just have unallocated space.

Drive A: is not a floppy drive, I dont have one present.

I don't have any software installed to manage the RAID1. Last time I tried to install the NVIDIA software ironically my RAID died due to hard drive failure. Since then I installed a card to handle it but I dont recall the information on the card. A friend gave it to me but here is what shows up when I looked it up in a program called "System Information for Windows by Gabriel Topala". I'm not sure how much of help it will be but let me know what else I could do to help

I figured you'd be asking sooner than later... Here is a screen shot of what I see at start up

The stripe, from my understanding, is controlled by the MB and then RAID1 is controlled by a controller that I installed. This is the RAID that I'm having problems with

So that's where you would go to manage your RAID (using the hotkeys displayed).

Two 2 TB disks should allow for a 2 TB RAID1. Why does it show in that bootscreen as 1 TB?

And what would A: be?

So have you gone into the management utility for the RAID controller that manages the H: drive? Hardware/firmware controllers can limit how Windows sees the actual devices. Was there ever a time in which the drive letter stuck successfully across boots?

I will reboot now and check it out

I don't recall it ever showing up since the new controller... I've been dealing with this for a while. I'll take some screen shots of the menus
