Not hacked !
It has a crack in it about 10 mm into the data part.It will still work after a slow start and I have a backup copy.The copy will not work without the original in place.Obviously this crack will get worse,is there anything I can do to stop the crack spreading ?
Thanks.

Nope!
If it's a game then find a no-CD patch for it or ask for a replacement from the software company who produce it.

Don't be tempted to use it either, because it is likely to shatter in your DVD drive.

Thanks for that,I will trythose nice people at EA games.

NEVER USE A CRACKED CD!!!!

Just a warning from someone who had one shatter in a drive and had to replace the drive. The cd gets everywhere!
