Fujitsu DynaMO under 4.25

Has anyone used a Fujitsu DynaMO IDE magneto-optical drive under QNX 4.25?
The drive seems to be okay, but when I copy files to it the disk responds
very slowly. I copied 40MB in Windows to the drive in less than 2 minutes.
I tried this sames test in 4.25 and it has been half an hour and the
operation hasn’t completed yet. Is there an option in Fsys.eide I should be
