interesting info...the checksum errors on my system popped up after literally hours of transferring files from a CF card in the pcmcia port to a 32GB DOM in the onboard IDE port...I believed a small electricity interruption in my house stopped the transferring and that's when errors started popping up......
so the new DiskDoctor with OS3.1.4 only 'examines' hard drives so what to use then on drives larger than 4GB's nowadays to try to 'repair' issues ?
