The problem does not appear if you do 256 writes of 512 bytes each. The error occurs if you do
one write of 131584 Bytes or more (> 256*512).
This means the problem only happens if all of these are true:
- you copy a file which is larger than 128KB
- your copy program has a buffer size of more than 128KB
- the file system is not fragmented, so that it can write the entire buffer (more than 128KB) in one command.

I remember from back of the days when I bought new 80GB drive and it trashed data while my original 80MB 2.5" drive didnt, and neither did 800MB Samsung or 1.2GB Seagate

Most likely the old drives followed the old ATA specs which didn't have the MaxTransfer problem while the 80GB drive is the next generation with new ATA specs.
It could also be that you didn't have a MaxTransfer problem but rather a >4GB problem. This really shows as random trashing of files, entire partitions or even the entire drive.
