Hello all, First post on http://data-recovery-data-recovery.blogspot.com/ , Like me (and many other computer users) you probably lost or deleted some file you wanted to recover and I'll try to talk about every thing you might try to recover your deleted files.
Always keep in mind that data recovery is never unfeasible, even in the worst circumstances. But to prevent to any data loss, make sure to take to basics precautions. A Hard Drive has a limited life, start to backup your data on CDR/CDRW on a regular basis, that's the best way to be sure sure that your data will not be lost.
Even if you get a virus on your computer, data recovery is possible. but again, installing a free antivirus (Avira, AVG, Avast....) is a good precaution to avoid a data loss
I'll try to cover some free solution tomorrow...
