When it comes to data stored on magnetic media like hard drives it’s not a matter of “if” the hard drive will fail, it’s a matter of “when” drive will fail. All hard drives including Solid State Drives will eventually fail.
Hard Drives have a magnetic cylinder that continuously spins at up to 10,000 RPMs. Moving parts can wear out and circuitry can fail. This is why regular backups are a necessity.
When a hard drive does fail there are several methods of gaining access to and extracting the data from the drive. Some of these methods being easier then others with the last resort being sending the hard drive to a clean room facility where they can properly dismantle the drive in order to recover the data from it. Should an unfortunate event with a hard drive happen we can assist you every step of the way to get it resolved.
The very first thing you should do after experiencing any type of data loss is shut down the computer. The more time spent on a computer that has experienced data loss the more chance that the data will be irrecoverable. After this step contact a professional immediately.
