I’m using Acer notebook (Travel Mate 2413 WLMi) with slimtype SOSW-833S too, VRS3 firmware. But there’s no autobitsetting checkbox in the OmniPatcher 2.4.3 when firmware is uploaded to this program. OP manual says that this feature were removed for the drives that remembers current bit set after reboot, for example, maded with LiteOn bookType utility. My drive doesn’t allows to change disc booktype, neither with LiteOn booktype utility nor enable it with related OP checkbox.
And another big problem of this drive - slow DVD burning speed… Speed is never reached value selected into burning software (Nero 126.96.36.199, Nero 188.8.131.52 premium). Recjrder hardware buffer indicator during burning sequentially drops from 98-96% to 21-25%, speed at that moments slows down to 325 kb/s !!! So , this drive burns DVD+R 4.7 Gb disks with MKM and YUDEN T02 media with 4 Gb of data (ISO or UDF filesystem - doesn’t matter…) for about 40 mins… Actual recording speed for the ANY 4x media is 2-2.3x…
833S works as primary slave. Primary master is 60 Gb HDD UDMA100. UDMA enabled for both devices, burst transfer rate for 833S estimated with Nero CD-DVD Speed is 22 mbytes/sec.
Can you comment this situation ? Or give any advices ?
