Analysis and Research Based on Hard Disk Protection Technology

Hard disk is the important external memory of computer.The system's software and the application's software must be installed on the hard disk,the user's processed data may also deposit on the hard disk.If the hard drive to protect properly,the damage caused is irreparable,therefore,protection of the hard disk is particularly important.The generalized analysis and the contrast research are carried on from the principles,functions,advantages,disadvantages and applications of the hard disk protection card.It is found that the card with the variable copy function and the multi-purpose protection cards can better protect the hard disk and the data of hard disk.And it can make more efficacious that disentangle computer manager from heavy reduplicate work.
