Hard Drive Sizing

Hard drive sizing can be easy or difficult.

Some hard drives are marked with a size. Some are not.

Hard drive sizes are general marked in gigabytes (GB).

Sometimes there is a label on the drive that lists its "geometry". This include a number labeled "cylinders". If this number is 16000 or less, you can cut that number in half to determine the hard drive size. If it is more than 16000, the drive will be 8 GB in size or bigger, and you will need to determine the size in some other way.

If the drive is not marked with its size, you may need to google for its model number to figure out its size.

Sometimes, however, you can read its model number and make a very good guess as to its size. In some cases you drop the first number off the model number to determine the approximate size.
