1 Cylinder = 55,996 * 15 = 839,940 bytes. 1 Megabyte = 1,048,576 (2 to the 20th power) bytes. 1 terabyte = 2 to the 40th power or approximately a thousand billion bytes (that is, a thousand gigabytes).
.
Just so, how many bytes is a 3390 cylinder?
A 3390-n device has a capacity of 56,664 bytes per track,of which 55,996 bytes are accessible by applications programmers. And 1 cylinder is 15 tracks.

How many tracks does a hard drive have?
There can be more than a thousand tracks on a 3.5-inch hard disk. Sections within each track are called sectors. A sector is the smallest physical storage unit on a disk, and is almost always 512 bytes (0.5 kB) in size. The figure below shows a hard disk with two platters.
What is block size in mainframe?
Block size (BLKSIZE) specifies the maximum length, in bytes, of a physical block of storage in MVS. If BLKSIZE(0) is specified, the system will determine the optimal block size based on the maximum record length (LRECL) and the physical characteristics of the disk, or approximately half of a physical track.
