It might be compatible, most likely but not fully meaning no FF on Rs and commercial disc, FF will work on RWs.
If the supplier has a good return policy, I would test it out just by opening the case and just lay the new drive on top of the one in the unit, put a piece of paper to prevent scratches, plug it up, power and test the recording capacity on RWs, Rs, justfit, timer and manual, finalising, transfers (hdd to disc, disc to hdd, both RWs and Rs).
Test the playback on Rs and RWs, all functions should work on the RWs (FF included) but no FF on the Rs. If the region is not set yet on the drive, they are sometime sold already set sometimes not. if the commercial disc won’t play, you’ll need to bring the drive to the PC and set it and play a commercial Disc while still on the PC, then install in recorder. If it didn’t FF on Rs, it will most likely not FF on commercial disc. The recordings played on other players will be fine, test that too.
If I’m playing a disc that can’t FF, I’ll chapter up then rewind, that works.
