Fixing slow usb transfer to iRiver P7 PMP

[QuantumKnot]

For those who have just bought an iRiver P7 multimedia player, transferring music and video to it in Fedora 12 is as slow as molasses (80 kB/s....)

After mounting the P7 (say as /dev/sdb), log in as root in a terminal and type the following:

echo 64 > /sys/block/sdb/device/max_sectors

Now you can transfer files across at around 3 MB/s, which is better than 80 kB/s

You have to do this each time the P7 is mounted though.
