Cyclic Redundancy Check
I have a 2G drive. I got an error Cyclic Redundancy Check. I right
clicked on the drive and tools. I am running error checking. I didn't notice before running the check that Explorer is not reporting "total size" It does show free space. The check has been running for about 25 min and the progress bar is only showing maybe 1%. If the drive is not reporting total size, does it seem likely that disk check/ fix will fix the problem?

I hope that is a 2TB drive and not a 2GB drive. A 2GB drive would be as old as my dead Barracuda. Use HDTune to evaluate the drive. The Health tab connects to the SMART system in the hard drive, and it reports on Reallocated sectors. If the "Data" field of Reallocated sectors is non-zero, then you have a fair number of reallocated sectors. A CRC error can happen, if you run out of sectors to use for reallocation, and so the drive has nothing left but an errored sector at that location. A CRC error can also be caused by a cabling problem. SATA drives keep a separate count of packet errors, and that counter cannot be reset (so, to notice fresh errors, you have to know the error count before you start, then check it again some time later). If the cable is bad say (has been bent or kinked), you might expect packet errors on the cable. The HDTune first tab is "Benchmark", and for a hard drive should be a steadily declining curve (say from 135MB/sec at the left, to 70MB/sec on the right). It's OK to have the odd sharp downward spike (that can be caused by the measurement method of HDTune, being interfered with by the OS or another program). But if large portions of the drive have low performance of transfer rate, then that is confirmation reallocation of sectors has been happening in a big way. I had a drive with a 70GB swath that was very low transfer rate, and seeing that told me it needed to be replaced right away. The SMART table in that case, still looked good. If all the problems on the disk are in one area, and not spread out, that can sometimes "fool" the SMART thing. Paul

It took at least 90min to go through stage 4. It took at least 60 min to go through stage 5. When I checked on the test, the total drive space was not reported. Before stage 4 was over, free space also disappeared. (From an Explorer window.) I was not watching when the test was finished, but I got no report that there were any errors found. Total space and free space are now showing up fine. If another error shows up I will order another drive to replace it, but I don't suspect there is anything wrong now. Thanks I will be trying HDTune

Thanks I will be trying HDTune I forgot the link :-) http://www.hdtune.com/files/hdtune_255.exe That's the free version, perfectly suited to this task of spotting bad drives. While you can use SeaTools or the WD diagnostic for their respective drives, those tests are mainly for warranty claim purposes. The test can return an (unnamed) error code, which is used to justify a return under warranty. Whereas using HDTune is more of a "user-oriented" test, checking things the user cares about. HDTune can sometimes warn you, when Seatools says nothing is wrong. And being free, you can't beat the price. There is also HDTune Pro, the paid version, if you wish to thank the developer in a tangible way. Paul
