Some tips for data recovery include not opening and exposing the hard drive and not using the computer or unnecessary programs until the data is recovered. In addition, if your hard drive is making an unfamiliar noise, turn off the computer immediately and refrain from using data recovery software.
If your data is critical, leave the recovery method and process up to professionals. It is important to remember that one simple mistake made during the recovery process can render the lost data unrecoverable. If data recovery is critical, do not try to recover data using do-it-yourself methods. In these cases, it is typically advisable to consult a professional for immediate assistance.
If you are knowledgeable on the subjects of hard drives and data recovery, and the hard drive in question is not making noise, research, choose and then purchase a reputable data recovery program. Download the purchased program and install it to the computer's hard drive, and create a desktop icon. Open the program by double-clicking the created icon, and then follow the prompts for successful recovery of your lost data.
Prevention is often the best solution. Back up important files often and at the first sign of any hard drive trouble.
