We offer trustworthy and fast data recovery services for PC, Mac, Linux, and RAID hard drives. Our goal is to provide the most affordable data recovery services for severely damaged and dead/dying hard drives. Formatting the hard drive is a bit more secure than simply erasing the files. Formatting a disk does not erase the data on the disk, only the address tables. It makes it much more difficult to recover the files. However a computer specialist would be able to recover most or all the data that was on the disk before the reformat.
The government standard (DoD 5220.22-M), considered a medium security level, specifies three iterations to completely overwrite a hard drive six times. Each iteration makes two write-passes over the entire drive; the first pass inscribes ones (1) over the drive surface and the second inscribes zeros (0) onto the surface. After the third iteration, a government designated code of 246 is written across the drive, then it is verified by a final pass that uses a read-verify process.

Perhaps you have decided to forgo system upgrades and get rid of your computer system and purchase a new one. If you've decided to donate your old computer to a charity, local group or school, it's extremely important to make sure your computer's hard drive is completely free of data. In the "no good deed ever goes unpunished" department, you need to ensure that you don't donate more than you planned.
The last thing you want is to pass on a PC when sensitive business information, or even personal information such as stored passwords, personal documents and credit card numbers that could be retrieved. When you donate a computer, you really don't know where it may end up or if it will go through the hands of a malicious person with the capability to restore previously recorded and deleted data.
