Someone asks you: "How much data can you put on a 3.5" floppy"

You say: "1.44 MB"

Wrong!

Here's why: 80 tracks * 18 sectors * 512 bytes * 2 sides = 1474560 bytes / 1024 = 1440 KB / 1024 = 1.41 MB my friends!!!

Now who was the full to do all the above calc and think 1 MB is 1000 KB in the last step?

Here's something funny...

Its actually 1.38mb. Redo your maths...

:rolleyes:

That is usable space after format. Two FAT tables and boot sector take up 16.5 KB (0h to 4200h) :)

Again, no!

Dos boot code = 1 sector (0h)
FAT1 = 6 sectors (200h)
FAT2 = 6 sectors (1400h)
Directory structure = 8 sectors (2600h)
Remaining data = rest of disk (4200h)

Two FAT tables & the boot sector take up 13 sectors.

I was including the root structure.

How many seconds are there in 10 years?

I'm not even getting in to this argument. :rolleyes:

I was hoping you would say 315360000. ;)

What? You can get at least 1.6MB on a floppy (use ADFS), and some filesystems get even more :D

Haha...

Its actually 63072000, so your around 252288000 to much there M8! :p

So much for not getting in to this argument - lol

For those of you who are puzzled, he meant binary 10, which is 2.

So 60*60*24*365*2

Hope everyone gets it now!

P.S I bet everyone looking at this post has reached for a calculator! :D

Ha, that one is goot too, but what I meant is that year is 365.25 days, so 315576000 :)

Yes, you can get even 2000 KB if you leave it unformated, but I was talking about standard PC format.

I meant of usable data ;)

You can get more than 1.44MB with FAT too, but I can't remember how.

Even unformated is usabele if you save raw data.

Yes, but it's quite tricky to do from software. Something whereby you can actually use it properly :)

No it is not....becasue every 4th year you have an extra day, but that is not exactly, so every 400th years that extra day is not counted, and so on, so it is not exactly 365,25....;)

Yeah, and plus its a floppy.

Gaining a few KB isn't going to help much is it? Hehe :p

Year is actually 365.242198 days long. Calculating more digits is meeningles with the precison of instruments we have (theese say Earth rotates in 23 hr. 56 min. 4.091 sec).
So, it's about 315569259,072 seconds.

Yes that is more like it ns-code....:D....now I am starting to like you...;)
