QpxTool is a CD\DVD check program that will help you check your disks for possible failures or lack thereof. But it must be said that this utility has a dual functionality and the point is this...
If, say, your disks are screwed up, there may be two reasons: either the disks are defective/broken, or the CD\DVD drive itself, due to its own wear and tear, is starting to fail? And although the utility only checks disks, it also helps to identify problems with the drive; if the disks are OK, then the drive is acting up - logically...
QPxTool depends on the disk used, not all drives are capable of reading Q-checks, and not all of them are supported by QPxTool. Currently, most new LiteOn, NEC, Pioneer and Plextor drives are supported.
