I recently formatted my HDD. Thinking I could back up my 2500+ files and folder using 7zip. I compressed into two parts and put one part onto each CD. I then tried to extract the files and also tried to copy the PART directly to the desktop, both times getting a CRC error. I read somewhere on the net that these are 'fake crc errors' as there is nothing wrong with the disc. If I cannot recover the files, there is a good chance I'll get fired. Please I need some help.
