Default Large IDE drives not compatable with old systems

put finger to keyboard and composed:

Is there anything else I can try?


In your OP you state that a "physical format" requires 8 hours. I
presume this is a full zero-fill of the drive.

If so, then the average data transfer rate would be ...

40 x 10^9 / (8 x 3600) = 1.39 MB/s

FWIW, that's much slower than the slowest of the PIO or DMA modes:

Does your new drive, when truncated to 40GB, complete a physical
format in less time?
