A hard disk can be either internal or external and one can use it to save files. The parts of a hard disk are the disk case, spindle, disk platter, actuator and the read-write arm.
putting them back in their case!!!! Always keep games in their boxes, never put them down except in a disk case. Hold them by the edges and/or the central hole only. Don't allow people who don't know how to handle a disk to hold them.
Diameter = 2*Radius So, in this case, diameter = 44 cm
A PSP UMD can't function without the outer plastic case surrounding the disk. The PSP won't even recognise it as there being anything inserted. So there's probably little chance of the disk or the PSP being damaged.
Hard disk
Nothing.
a flat object that holds computer data is a disc

The hard plastic case has a slider in it which you can use to open or close the notch as you want. When the notch is open the disk is write protected.
first you open the case second you take the disk out third you open the player then finaly put the disk in and shut the playe idiot
Depends on where it comes from. Disk defrag programs are generally system utility programs, however, you can download some disk defrag programs from websites. In the latter case, it would be considered application software.
