The amount of money it will cost to recover data from a Mac varies widely based on the method and product used to perform the recovery. Assuming that you do not have a backup of the data and the lost files are not in the Trash, you essentially have three options.
Freeware - You might be able to recover your lost data for free using a freeware solution. If you choose this route, be prepared for inconsistent recovery results and the possibility that you will be using a very basic or command-line interface.
Commercial software - Reliable commercial data recovery products can be obtained for under $100 and offer a much more intuitive and consistent recovery experience compared to freeware alternatives.
Data recovery service - When data recovery software fails, the professionals at a data recovery service may be able to restore your data. This is the most expensive method and can cost several hundred or thousands of dollars.
Apple has included a built-in data backup and recovery program called Time Machine in all modern Mac operating systems. Using this app allows you to create regular backups of all the files in your machine, which you can later use to restore any data that may have been accidentally deleted or lost. The catch, of course, is that you need to consistently create backups on a designated driver to ensure that you have a source to recover files from.
I have an old MacBook Pro A1278 I'm working on that currently only has an install of Windows on it. The HD partitions were totally wiped, so there's no access to the normal recovery tools you'd use to reinstall OS X.
If the Mac is new enough (A1278 covers a range of models Opens a new window Opens a new window spanning a few years), you may be able to use Internet Recovery. Power on the the machine, and immediately after hearing the Mac boot chime, hold down Command+Option+R. If it works, it will step you through connecting to wifi if needed, then will download and install the OS. Full details here:
Glad you got it working. If you want to upgrade to El Cap at a later date, you should be able to download it from the App store Updates section. Internet Recovery only installs the OS version that came with the device.
Even if you completely wipe your Mac, and start again from scratch, the Recovery partition should still be there to make it possible to reinstall macOS, restore from your Time Machine backup, and repair or erase your hard disk. We look in detail at what you can do in Recovery mode here.

Depending on what this disk was used for most recently, the partition scheme could be anything. In order to convert it to the GPT scheme, you will erase the disk. If it is already using the GPT scheme, this is not strictly necessary, but you should erase it just to be sure.
It is also possible to partition the disk, and use only part of it for OS X Recovery. The download page has a link to more information about OS X Recovery Disk Assistant, including the partitioning procedure.
If you are preparing to create a Recovery disk, you do not need to change its name from Untitled; however, if you are preparing to create an Install disk (Exercise 4.3), you should give it a descriptive name.
Since you erased the entire disk, rather than a single volume within the disk, Disk Utility has rebuilt the partition map as well. Although a Mac OS Extended volume can be created under any supported partition scheme, Disk Utility created a GUID Partition Table because it is the best fit.
If you have already completed Exercise 4.1, then you have already experienced OS X Recovery, and you can start up from your normal startup volume instead. Unplug the external disk, select the Macintosh HD icon, and then click the up-arrow button below it.

One feature of Windows NT/2000's (Win2K) C2-compliance is that itimplements object reuse protection. This means that when an applicationallocates file space or virtual memory it is unable to view data thatwas previously stored in the resources Windows NT/2K allocates for it.Windows NT zero-fills memory and zeroes the sectors on disk where a fileis placed before it presents either type of resource to an application.However, object reuse does not dictate that the space that a fileoccupies before it is deleted be zeroed. This is because Windows NT/2Kis designed with the assumption that the operating system controlsaccess to system resources. However, when the operating system is notactive it is possible to use raw disk editors and recovery tools to viewand recover data that the operating system has deallocated. Even whenyou encrypt files with Win2K's Encrypting File System (EFS), a file'soriginal unencrypted file data is left on the disk after a new encryptedversion of the file is created. 2ff7e9595c
