I can’t not really… It’s a long time ago and at the time I was working for a large computer firm in the UK. It would have been around 1990 ish, may be even 1989, and my job was IT support. PC’s in businesses were quite a new thing back then and as I had just graduated from college and knew comparatively a lot about PC’s I got the job of supporting them.
Now, how big were hard drives in 1990? Without researching it I can’t remember but their capacities were certainly in the Megabytes, and the low megabytes at that… 10Mb maybe? A couple of years later I remember that Windows 3 had just come out and after it had been installed there wasn’t any room on people hard drives to load anything else like WordPerfect, which was the de-facto wordprocessor of the time.
One thing for certain is that hard drives in 1990 didn’t really look like they do today – the only similarity is the metal box shape. Most hard drives had either SCSI and PATA interfaces too. The modern SATA interface that we see today didn’t come along until much later – about 2009.
