I have a DW1655 with BCIB firmware. I was running with HB for some time, and then the drive read speeds while using DVDFab or other ripping tools began to slow significantly. Ripping a movie used to take 6-8 minutes, while now it can take upwards of 20. Transfer rates hover between 2-5mb/s. The drive used to speed up to 16x to do the read, and now will occasionally start up at 16x, but then slow down to the slower read rate.
Thought the new IB firmware would clear things up, but still getting slow reads. The slowness is apparent in both old (produced several years ago) DVDs and new DVDs, so it’s not related to encryption.
Burns can sometimes be slower than normal, but will still burn at 16x. The read/rip time is what’s lengthening.
CD burning (mp3 or CD audio burns) are unaffected, although I have noticed that the read speed has noticeably decreased.
Can anyone think or suggest ways to troubleshoot this?
