Teach how a hard disk drive works

Visual Hard Drive simulates the operation of a computer’s hard disk drive and shows how a hard drive works. The virtual drive has a controller board, four magnetic platters and eight read/write heads. Up to 32 bits of data can be written and read from the hard disk drive. The drive simulates data being written and read from the top platter and shows how a hard drive works.vishd5
Virtual data can be written in a safe environment. Data can be read from the virtual disk and be displayed as binary, bytes and ASCII.

Visual Hard Drive has four magnetic platters and eight read/write heads.

Data limits
Our hard drive is fixed to write at sector 1 from here we can write 32 bits of data. In total 32 bits of data can be written to the disk.
The program simulates data being written to sector 1. The start address is 0000000200 Addresses are offset from this start address.
Write to disk

Every part of the platter has its own unique capability to store a binary 0 or binary 1 when writing to the platter the magnetic surface will contain either 0 or 1. In our simulation a red dot signifies a 0 a gap signifies a binary 1. As the disk is spinning all the time a circular data trail is left.
Visual Hard Drive shows how a hard drive works.



Teach how computer storage works…

Different types of computer storage abound these days from the hard disk drive central to any windows pc’s operation to USB Memory sticks used for temporary storage. With computing and computer science taking a greater role in education we have introduced a new program to cover the computer storage aspect of the computing curriculum at key stage 3, also useful for computer science k-12.
