The Bigfoot was a rare example of a modern IDE drive produced in the 5 1/4" form factor. These were a budget drive often found in low end PCs of the time. The capacity started at 1.2 GB and went all the way up to 19.2 GB. This example is 4.3 GB and was installed in my first PC which I bought in 1997. Bigfoot drives were generally slower than comparable models of the era, in part due to the slow 3600 rpm spin speed - 4500 or 5400 rpm drives were commonly available at the time. No other manufacturer since has been interested in producing drives of this form factor. So the Bigfoot occupies its own little niche of PC history.
