Journal entry #4 for my Operating System class (others are here if you’re interested). Here we had to outline the disk capacity and usage of each of our computer drives using the dir command or the File Explorer on Windows.


My operating system is Windows 10, and I decided to use the File Explorer utility solely because the command-line prints out the sizes in bytes and I am too lazy to do the math. I would also probably do it wrong, even with a calculator.

I have 1 internal hard drive and 3 external hard drives attached to my computer. My internal drive is the drive on which Windows is installed and is drive letter C. This is where the majority of my non-portable programs are installed as well. This is my most-used drive and has a maximum capacity of 1.81 terabytes, of which 333 gigabytes are free.

The next in line of usage is my external drive on which I store all my entertainment. That is drive letter M, because on my old system it was drive letter M and I didn’t want to lose any of my links and file references when I transferred over. Sure, there are utilities and such you can use to fix that, but it was easier to just set the drive letter upon installation. This drive is nearly full, with only 20 gigs of free space left on a 1.81 terabyte drive.

My photo and file backup drive is the next drive in line, where I store all my photos and documents. This would be the drive I would grab if I could only take one. This is set as drive letter B and has a total space of 931 gigabytes, while I’m using 805 gigabytes of that space.

My last drive is the newest addition to the family, bought as a replacement for the smallest drive, Z. This one has no usage at the moment, with all of its 1.81 terabytes free.
