denret Posted November 25, 2011 Share Posted November 25, 2011 What is the "Reset DMA" check box do? The reason I ask is because I'm searching for answers to a read problem... having trouble with CRC and ECC errors when attempting to create an Image File off of a Double Layer BD (8.9g). Can't get through the disk with a SATA connected external drive, but move it to my internal IDE drive and it reads all the way through every time. I've cleaned the lenses on the drive, adjusted the read speed settings, checked "ignore read errors" etc., no results??? Puzzled???

Cynthia Posted November 25, 2011 Share Posted November 25, 2011 Some older OS can revert to PIO mode and the reading/writing is slower. E 10:56:16 Average Read Rate: 3,366 KB/s (2.4x) - Maximum Read Rate: 7,795 KB/s (5.6x) Doesn't look like your issue is this based on the speeds. Looks more as a crappy burn that can't be read back. Some burners are better readers than others. Link to comment Share on other sites More sharing options...

I hadn't thought of bad burns, more I was thinking of bad disks, but had just about ruled that out because of so many different disks involved......but all of the disks sampled were burned on the same burner. I guess I can live with the warning line in the log file: "Duplex Secure's SPTD driver can have a detrimental effect on drive performance"??? I was kind of curious about that too? Thanks again Link to comment Share on other sites More sharing options...

Thanks again One more nugget.....the drive is question is an external sata connected. I can move the same disk to a internal IDE on the same Vista machineand read it perfectly every time.
