I must admit, I was assuming Sinclair had used 1024 byte blocks on his microdrives - I may need to be corrected on that. > Of course, the capacity decreases when you format the disc as > well (how did they work out the unformatted capacity, > because, if it is unformatted then you cannot store anything on it !) Stephen Usher's description of the perils of formatting is amongst the best I've ever seen. It's true that you can lose staggering amounts of disk space to a bad file format... However, I think anything in the 3 to 4 million microdrive equivalents will probably last most of us for a while yet (unlike a 400GB PC disk, which at current rates will be obsolete in 18 minutes and 23 seconds).
