I don't have time for an organized test right now, but I've been
using my own flashed build of pure Rockbox-cvs with the optimized
read/write routines turned on for quite some time. The only problems
I had during all that time were clearly USB-related and didn't occur
during normal operation.

ROM: 1.28
Mask: 0x0302
USB: positive
ATA: 0x200, master

Model: HITACHI_DK23DA-20
Power mgmt: enabled
Noise mgmt: unsupported
Read-ahead: enabled
PIO modes: 0 1 2 3 4
Cycle times: 240ns/120ns
IORDY support: yes
IORDY disable: no
