Mikulas External  

All the computer systems have in any case one hard drive where information gets stored. Typically, these are positioned internally but as the computers get evolved external hard drives are becoming very much a part of the modern computers. They are an external storage space in which sensitive data may be kept in a secure and protected environment.

They are mainly used for backup purposes. Spyware, Trojans as well as viruses are all security threats to data inside the computer, when internet is being accessed. Also, since the computers have usually been used by several members the probability of any sensitive file getting corrupted is rather high. The best thing to do would be probably to buy new 1tb external drive disk.
