Easy Fix for Older Sony Vaio Computer With Small C Drive

I have always liked Sony computers, and because they have performed so well for me, I have advised other members of my family to purchase computers from the Sony Vaio line. These systems usually last forever, and they are great for video editing and working with multimedia.

Unfortunately, older Vaios almost always have a partitioned hard drive, and the C drive may not be large enough to handle all the automatic updates and patches that accompany much of the newer software on the market. It can be very frustrating if you have lots of hard drive space left on your D drive, but you can’t defrag your system or do a system restore because you don’t have enough space on your C drive.

A number of forums advise users to delete unused applications and files from the C drive or to move them to the D drive. This doesn’t always solve the problem, though, since many updates will automatically be installed on the C drive, so it fills up again before you know it.

There are a number of ways to fix this problem. Since I didn’t want to spend a lot of time or effort on these older machines, I recently did a little research to find the quickest and easiest way possible to resolve this issue. Since I know there must be others out there who would love to keep that old computer running for just a little while longer, I decided to share this information.

This is how I fixed the problem in less than an hour.

  1. I found a free download of Partition Magic 8 on the web. If you can’t find a free version, keep searching. There are some out there. I found mine by searching YouTube.
  2. I downloaded this software to the machine I wanted to fix. The serial number that was needed to activate the program was included in a folder called “Documentation and Serial” in my download, but I didn’t realize this until later. Instead, I Googled the terms “serial number for Partition Magic” and found a posting that provided a serial number, and it worked.
  3. I opened the newly installed program and used the option “Redistribute free space” which is located in the Pick a Task panel on the left side of the screen.
  4. When prompted, I indicated which two drives I wanted to include when redistributing the free space (C and D).
  5. I let the program do its magic. It took about 15 or 20 minutes to finish the task, and now the Sony Vaio has enough free space on the C drive to handle all of the pesky updates and patches that are thrown at it.

    That’s very helpful. Thank you. I hate it when a notebook computer like my Acer has a 50/50 allocation between C drive and D yet the C drive requires about 85% of the space. Partitioning like that is ‘permanent’ and just not intelligent. IT education needs to cover these issues. GD.

    Yes I have Sony Vaio and it works very good and I cant believe hearing from you that It’ll be last forever. Thanks for that information, It’s true that the old systems do not preform well.

    I still have my Sony Vaio and I see no reason to throw it away now. Now that I’m armed with your information, I can keep my Sony for a very long time.
