no longer reading 2-layer discs

[xwmkf]

I have a pioneer BDR-206, bought back in 2011, used for many years, but not used in the last few years; I plugged it back in recently, and it looks like it now will mount only some BDs -- after testing 30 discs, it looks like the few it mounts successfully are all 1 layer discs, and the many it doesn't mount are 2 all layer discs (according to another drive that mounts them).

Is there anything I can do to/for the drive to help it work again?

Thanks, I'll take a look at that.
