Hi all, having a 250 GB drive on a PATA strip using lowest PIO mode (without dma if possible), drive specs show a 8 MB buffer ,
2 cases are : on same pata strip, one on each strip, important to note that the booted drive is the if's straight up to my slave. (yea i know ill have to run fsck afterwards since itll think it still mounted) and having no user but su himself. i had ran mine at 4mb block space thinking ill use the 16mb bus transfer divided at most in 4, per second, but i achieved that in a minute instead. this is really poor performance, 3 days for 250gb transfer at 4mb bs dd if=/dev/wd0c of=/dev/wd1c bs=4m so what if i was to use dd if=/dev/wd0c of=/dev/wd1c bs=4000m or more, or reflecting number sector divided by lets say 16... would in the end i get the same effect, what are the plateau i should top of, a mb is way too cheezy i have 512mb of ram, would 512mb be the most ? the machine is idling either way. neko
