D drive space is missing, and I can't allocate it "ubuntu"

[Asdosss]

Hello,


I uninstalled Ubuntu, and I installed Windows 7 because I couldn't restore my system, but a free space went missing with no reason, and I am not sure if I deleted the d drive or not. Furthermore, I lost more than 800GB. A page pops up when I start my laptop, and it shows that I still have the free space, but it is not shown either in computer or disk management as unallocated. I have tried so many programs to get back the 800GB and use it, but nothing seems to work. I will attach two pictures, the first one shows my disk management, and the second picture shows the page that pops up everytime I start my laptop. Long story short, I installed Ubuntu using Wubi, then I didn't like it that much, and I tried to format d drive, then I deleted by mistake. Now the d drive is shown, but missing around 800GB. I am really pissed

I am not sure how many Gbs that exactly I am missing, but it is around 800GB
I will appreciate your help, please.

You really shouldn't mess with any of it if you don't know what you're doing.

It seems you had a striped RAID and now some of the drives are gone. The question is if it was a software or hardware RAID.

To start open the PC and look how many hard drives you have. It would seem by the Intel RAID utility that you had several Toshiba 120gb drives and a separate 1tb WD drive. Can you confirm this is what is physically installed?

We see nothing but problems here with RAID. Seriously, in six years since beta not one single good report but week after week there are nonstop reports of problems and lost data. The best advice I'd give anyone with a RAID is to back up the data and unRAID the drives, install the OS on the fastest and store the data on the others.

It may be too late unless you can reconstruct the RAID. But if you had no idea how any of this was set up in the first place, then it was bound to happen anyway because RAID is unstable and only causes problems in Win7.

so is there a way to fix the problem?, and how to fix it if it's possible? Thanks.

I don't care about the data as long as I can get the free space back, that's what I am asking for.

You need to break your RAID to get the free space back(of course you will lose all your data if not backed up somewhere else). You are losing the space because you have included the big drive in the RAID, which has 119.2GB as the smallest disk, effectively you are losing 931.5-119.2=812.3GB because of this.

If you wish, after breaking up the RAID, you can rebuild it with just the 3 small drives and the 931.5GB will be available as a separate drive.

I asked you specific questions which you ignored and then bumped the thread which is against the forum rules.

Still waiting for the answers.

Well I am going to try what you suggest me to do it, and I will reply as soon as it is fixed. Gregrocker Yes, I have three 119 Toshiba drives and a separate 1tb WD drive.
