Can ECC be disabled on a hard drive to speed reading of data? I realize the data may be bad, but I will figure that out myself after making an image. It just takes soooo long to copy a drive with lots of ECC errors. If possible, what is the best way to do this? Can I do it through SMART commands? Private mail here is fine if you don't want to tell the world.

JFYI: Read Long - uses PIO mode 0, 1 sector at call transfer - most slowest way to read data. Also if you don't use ECC each read can give different data :wink:

Maybe just limit the ECC retries , if you have the power

Probably why they called it "read long." :-)
