Recovering the lost data is very difficult but losing data is very easy. If the loss of data was due to physical damage then you need the help of a recovery expert. It wouldn't be wise to try to overcome computer hardware failures on your own unless you are an expert.
Nowadays, if the data loss was due to error or logical failure then the solution is deleted data recovery software program. The data recovery software should be certainly able to:
Even after shredding the data from recycle bin, it should be able to undelete data.
Recover lost or deleted data from virus infected files
Should be capable of recovering formatted drives, corrupted data and data lost due to system crash
Various types of data like music, audio and video
Should be able to recover all storage mediums such as hard drives, external drives, CD ROM, usb drives, floppy disks etc.

The simplest way to refrain from data loss is to begin taking computer backups of your significant storage mediums. Either make computer backups of data on CD-ROM's or use an external drive or zip drive to back up your vital data. If you'd like to go further try to find software program that automates the procedure of backing up and storing your data. These computer programs are type of "set and leave". You schedule the software to take computer backups at particular time or every day or month etc. and let the software program do the remaining.
