I have a Maxtor 80GB (not sure of the part # and I don't know if it is relevent) that has thousands of CRC errors scattered all over the drive in no obvious pattern. The last thing the user did before having problems was defrag the drive. He then received an error message and tried rebooting to fix it. The machine wouldn't boot because of errors on the drive. I'm guessing that something went wrong with the hardware on this drive during defrag and that his data is, for the most part, gone. I've tried a different PCB, no help, same sectors bad. It seems like moving the heads would be a waste of time. Any second opinions?

Thanks,
Phil

Hello,

Apparently this drive have overheated and had written with errors resulting from the excess temperature.
there is nothing to do with the bads, if U rewrite they may be fixed, but the drive needs cooling.

Hello,

i have the same problem too, the Maxtor 2B020H1 drive, there is 2 partition inside and after doing defragment the second partition sis'nt detected.

I think there is a bad sector, how to retrieve the data on that second partition?? thanks guys....

This is possible if your RAM isn't stable! More likely if the RAM is overclocked and/or has aggressive timings. (lower latency settings then stock)

This is possible if the RAM is overclocked too much or using too low of latencies. If your SDRAM timings are 2.0-2-2-6, you may be required to change it to 2.5-3-3-7 or to at least 2.0-3-3-6.

You may also be required to increase the VDIMM value, if overclocking your RAM! Not all motherboards have this option!

But you usually also would get a BSOD if the above was the cause.

Also, the above symptoms can occur if the PCI bus is overclocked.
Most Via chipsets don't have a PCI lock for when you overclock the bus!

Heard that even some nForce4 motherboards don't have a working PCI lock!

The standard PCI frequency is 33 Mhz. (not PCI-E!)
