    Small C Drive


    Just recently, I had a hard drive failure and sent my laptop in to Toshiba to have it repaired. The hard drive was replaced, but the C drive, which originally had around 700 GB of disk space, now has 89.9 GB. When the computer was returned, I noticed that there was a new drive named "New Volume (F: )" which has 607 GB free of 607 GB. I'm guessing this is where the rest of my space went but I don't know how to access it, or use it as my C drive. Normally I would fix this myself, but I don't know much about drives and partitions. If someone could give me a walk-through on how to use this F drive as a main drive with Program Files, etc. that would be great. My laptop is a Toshiba Satellite and I would like to save all of the data currently on the C drive (it's full).

    Thanks.

    P.S. My laptop # is S855-S5378

    Ok. Let's go step by step !

    You drive has been partitioned. You can see detailed disk information about all volumes in Disk Management (Console). For the system partition I think that 200GB would be more than enough for most users, even heavy ones ! Try to shrink drive F:\ (~110GB) to generate free space and add it into c:\. You can also use some third party softwares to do that.

    Okay, I managed to shrink about 600 GB off of the New Volume drive. Now I cant extend C because the option is blocked out. Click image for larger version Thanks a lot for helping me with this by the way, you've been very helpful so far. I will also try other software.

    I think what the factory people did for you is perfectly OK & good. Normally, you'd want your C drive to be small and contains only Windows 8 OS and all the installed applications in C:\Program Files or C:\Program Files (X86). That's why they partitioned your 700GB physical disk into 2 partitions so that you'd want to save your data in F: drive. There's a good reason for doing this:


    1. It's easier and faster for you to back up your Windows 8 OS + Installed applications.
    2. Keep your data separated from the OS + Installed applications, so in case if something goes wrong with your Windows OS, it'll be easy to fix/restore without worrying to lose any data.
    3. Windows would run better if your C drive is small because it only contains your Windows OS System Files and installed programs and will be less fragmented, less search time for files.

    I don't know why your C drive takes that much space and only have about 6-7 GB left. May be you have a lot of data stored in C drive + Temp Files + Junk Files + Pagefile.sys + Hiberfile.sys etc... I suggest that you leave the C: drive the way it is, 90GB is more than enough. What you need to do is re-organize it, move your data from C drive to F: drive. My C drive is a 128GB SSD, I have tons of programs installed and it only takes around 40GB. All my data is stored in a larger drive and it is much better this way in case my Windows becomes unbootable or if I need to re-install then I don't have to worry about losing data.

    Hope this help !!!

    EDIT: To answer your question about not being able to merge because the partition that you want to merge need to be adjacent to C drive. You'd have to use a third party Partition Manager to do it. You can download a free partition manager in the link below:

    Thanks so much! I got it to work with the third party tool. The reason my C drive is full so quickly is because I'm a gamer, and i use a web shop known as Steam. (I don't know if you're familiar). All games on the store are around 10 - 6 GB to download and I have a lot of them. As for why I cant use the F partition for these games is because Steam has a bug that restricts it from moving the root folders to a new partition in Windows 8. I don't know when or if they will fix it, so I wanted to move the space but I didn't know how. Again, thanks a lot for the assistance.

    I am not a gamer but just FYI. SURE you can move Steam or any game to F: drive. All you need to do is create a junction link for Steam.

    Assuming that Steam is installed under C:\Program File so there's is a folder C:\Program Files\Steam. What you need to do is as follows:
    1. Move Steam Folder to F: drive so in F: drive you would have a folder: F:\Steam
    2. Open the elevated command prompt and type:
      mklink /J "C:\Program Files\Steam" "F:\Steam"
      This effectively makes Steam as if it was installed under C:\Program Files but the storage for Steam is in fact under F:\Steam

    90 GB is not so small, I don't know how you managed to fill that so quick, it is all programs or are you storing data there as well? 90 should be plenty to run Windows 8, but any partitioning program will allow you to change the sizes of your partitions without losing any data. The larger your system drive and the more free space you have, the better your pagefile will work.
