A laptop data recovery is no different than a data recovery for a PC. You data recovery options come in two forms

If you still have access to your hard drive you can purchase software that will retrieve all the missing data. If your hard drive does not have physical damage it has logical damage, which can happen from a computer shutting down by accident, a virus, or logical drive repartitioning. If any of these things happen, the data is not properly stored in your hard drive. In order to get your hard drive working properly after logical damage you need to make use of a disc repair tool, which you can get for free. This type of free software deals with a loss of data by consistency checking, which involves scanning the hard drive to check for any inconsistencies. CHKDSK is a consistency checker available for Windows and Disc Utility is available for Mac. These utility programs can help prevent data loss because they form recovery files, which can be accessed later if something goes wrong with your hard drive. File or data carving puts fragmented files back together, thus recovering data in the process. You have to keep in mind that file recovery programs are not perfect. They may not get you back all of your files and the files that they you do get back may be corrupted and unusable. A lot of the laptop hard drive data recovery software programs are free to try and cost around $40-$50 to buy. Examples of file recovery programs include PC Inspector File Recovery, Pandora Recovery, Norton Utilities/SystemWorks, GetDataBack, and EASEUS Deleted File Recovery. If you happen to have manually deleted something by using the trash or recycle bin, you can sometimes recover it with free software because nothing wrong has happened with your hard drive. FINDNTFS Freeware is one of the few data recovery options, which is known to work. Pretty much all of the file recovery programs cost money because the makers of these products know that there are a lot of desperate people who will pay money to have their data recovered. If you realize that you can't access some of your data, the faster you start the recovery process, the greater chance there is that your files will be recovered.

If, however, you don't have access to your hard drive (it has physical damage to it), you're going to have to make use of a professional laptop data recovery services. You usually mail in your hard drive to one of these companies and they'll retrieve the data for you with their special equipment. Although it certainly won't be cheap, it is the only option you have. Unless you own or are employed by a data recovery company, don't think of trying to get the data back by yourself. These businesses charge a lot because they have a lot of expertise, special equipment, and rooms that are so clean that they are certified. Don't be surprised to be charged over $1,000 to recover most of your data. Essentially, what these companies do is repair your hard drive while extracting as much data from it as possible. If you try repairing the hard drive by yourself you're likely going to make things even worse because you have to recover the data in a squeaky clean environment.

If you want to prevent having to deal with getting back your data you can make backups of your data, on a CD or USB hard drive for example. Whether you recover the data using software/freeware or hire someone to do it, keep in mind that nothing is guaranteed. If your hard drive has physical damage you can expect to get back at least 90% of the data.
