Problem:

I use SuSE Linux 7.2 and when I create md5sums from damaged files on a 
CD, the WHOLE system  freezes or is ugly slow untill md5 has passed the 
damaged part of the file !

My CDRom drive is a HP8100i  IDE CD Writer attached as HDD at the onbord 
IDE Controller



test case:

md5 "/cdrom/damaged file"
