- Hmmm, mine says 39 sectors for the 30104. This gives a capacity of
- 116M for the drive which is almost acceptable. I have to admit I was a
- little cheesed off when I discovered my 120M drive was 4M short, but I
- would have been extremely annoyed if it had been 16M below the spec.
-
- BTW, my drive is a 30104H, if that makes any difference.

- Yes, another thing that worries me about these drives is that I was
- able to specify a translation that was larger than the actual capacity
- of the disk (this is how I verified that the actual capacity was
- indeed 116M). I think the translation I used was something like 1219
- cyls, 12 heads and 17 sectors.
