Sounds like he might have an Amstrad or maybe a spectrum!!!!!
In 1993 had a Power Mac with an 8 Gig, yes a whole 8 Gig hard drive. Mind you that was plenty then as there really wasn't an awful lot you could do with it. Plus it was a Mac so you couldn't plug much into it or programme it with.
Exiled amongst the red and white, at the wrong end of the A/M27.
I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion, I watched c-beams glitter in the dark near the Tannhäuser Gate. All those moments will be lost in time, like tears in rain.........Time to die.
There are viruses that duplicate files continuously until your hard drive is completely full, which usually renders it useless. Try running an AV scan of some sort, avast and AVG are good free antivirus programmes that may do the job.
Another solution is to buy a new computer because seriously, windows 98 and only 8gb hard drive... You can get phones that have 4 times as much storage as that mate...
