| Post subject: | CopyR.DMA ignores ECC? |
Does CopyR ignore ECC errors? Reason I ask is I've been trying things like ddrescue, Media Tools Professional, HD Duplicator Demo (where you cannot select ignore ECC) to image a drive and I simply cannot get the data from the bad blocks and the programs report it as such. CopyR however so far has read the first 10+% of the drive with zero errors. Surely it does not just ignore bad blocks & skip them, usually if there is an error it is indicated in red and the error counter increments. I just created and image file of the imaged drive and there is a boat load of data in the image I extracted via file carving. I don't have time to scan through all 24000 files but those I have looked at seem fine. Anyone care to comment or enlighten me? |

HD Dupl got an option named "Read without check of control sum", implying a statistical analysis. As far as I understand this applies to handling of "UNC" errors. |
