How'd you figure that out?

 

[bozo1]

cylinders x heads x sectors/track x 512

Sectors are 512 bytes.

I assume you pulled those numbers off the case of a Maxtor drive. You can't tell the capacity by those numbers. Either give us the model #, or go to maxtor's site and plug in the serial number, to get the capacity.

 

[bozo1]

can't tell the capacity by those numbers

Course you can, using the formula I supplied.

 

[Pariah]

Your formula is accurate, but the numbers on the drive are not the numbers you tried to plug into the formula.

I have a Maxtor on my desk here. Tell me the capacity:

16383 cylinders 16 heads 63 sectors

8.455200768Gb according to that formula 🙂

Is that correct Pariah, using that formula? I have never heard of that before, but it could very well be true, I am a n00b when it comes to things like this.

And the correct answer is 60GB...and 15GB...and 100GB...etc. Every Maxtor drive over 8GB has the same set of numbers on the label.

Is that correct Pariah, using that formula?

Yes, and no. It doesn't really work with today's drives because it assumes uniform sector/track count throughout the drive which doesn't happen any more with zoned bit recording. The easiest way to calculate capacity and really the only way today is total sector count x 512 (bytes per sector).

Bummer, that method was really easy too!

Pariah, could ya give a formula like... what x what x what / what = size 🙂

If you could understand that ur a genius!

The only realistic method of manually calculating the capacity of a drive is to know the total sector count of the drive. The only place you could find that info is on the manufacturer's website, and it would be much easier to just get the drive capacity of their site than try to look up the info necessary to calculate it yourself.
