Data Transfer Rates states the maximum speed at which data can be read/write onto the storage disk.
disk rotational speed in RPM
disk rotational speed in RPM
A few years ago people used to insert floppy disks into the disk drive to transfer data from computer to computer and to backup their work stored on the internal hard disk. Nowadays, people generally transfer data via the network/internet or use a disk-on-key that is inserted in a USB port. People might also burn a CD or DVD with their data.
One way of recovering data from a dead hard disk would be to get it repaired at a computer shop and buy an external hard disk enclosure that is compatible with the hard disk. Then you can mount the hard drive and transfer data across to the desired computer.
It sounds like you are trying to install a program, and it needs the data disk to be put into A Drive.
Data can be stored on floppy disk, hard disk, memory stick, CD or DVD.
There are many ways to clean the data on a hard drive disk. These ways include erasing and formatting, data wiping aka data dump, and disk wiping stands.
It wipes out data on the hard drive disk.
A disk drive work in a rigid magnetic disk fixed permanent drive unit, and used for storing comuter data.
