ErAce is software that will over write hard drive 1-100 times. So it fullfills strictest security standards i.e. DOD 5220.22-M. In that way it is impossible to recover data. If you delete files and empty the recycle bin it is possible to recover data with recovery software. ErAce will write the whole hard disk and put it to zero at the last cycle. After the process the hard drive looks like it just came out of the factory. ErAce works on Pentium or higher and AMD equivalent systems. It works even Intel based Mac computers. It needs 128 MB of memory.
With ErAce you can recycle, sell or throw away hard drive carefree. There is no way for other people to recover data, pictures or documents from your disk
