Well, I replaced the 3220, and that didn't have any effect at all. Let's hope it's the SATA-USB bridge!

Appreciate the PM all the same, I did finally get it here! Will give it a go - Thanks!

Hmm, it looks like private messages are empty - I would have expected with the posts I'd have that I should be able to receive them by now! Is it just a post count before their activated or is it a timeframe?

Hi Coppervid! I just picked up a BDR-XD08B, and I'm curious if this one can be cross flashed for UHD? It looks like it's at the firmware RIGHT before the cutoff!? Drive Information OS device name: E: Manufacturer: PIONEER Product: BD-RW BDR-XD08 Revision: 1.01 Serial number: BKDL001945UC Firmware da...

Quick update here, replaced the 3220 with no effect

awaiting new MB86C311Bs now.

Hey @Compucat, did you ever get anything further figured out - I have a BDR-XS07 acting the exact same way here. All rails look good. On the oscilloscope, I didn't see any data ever leave the usb/sata bridge, but I also saw some suspicious lack of signals on the usb controller. I've ordered some new...

It looks like that IC is bad! I'm seeing voltages come into it, but no communication at all out of it. I've ordered a couple of replacements, as well as a the usb-c controller IC, just in case there's something going on there as well. It's worth a shot anyway. Here's some of the IC's on the board if...

Interesting, that could be what I'm seeing on this one. All the major chips have power, nothing appears to be overly hot, and I can see the initial communication happen on the bios chip, but then stops immediately and nothing else is happening on the MCU. I've got it all apart again now (needed to r...

I'm curious, what about the XS06 model is so different from the other drives that makes it one that won't be flashable?

I'm in the middle of a repair attempt on a BDR-XS07 drive that doesn't respond at all when plugged in. I'm still tracing power to confirm it's getting everywhere it needs to go, but I'm hoping someone can shed some light on flashing the bios chip out of circuit in case power is all good and this was just a bad flash - I have a programmer, but i'm curious if these drives need the ROM chip flashed and maybe also some additional stuff flashed beside the mx eeprom on the board?

Currently the board isn't recognized at all when you plug it in, but i've been able to confirm the main fuse appears to be good, still need to trace it to the rest of the chips with datasheets. If anyone has any details that might prove helpful, any direction would be appreciated 😀

Hoping @coopervid might pop in here... 😀
Flashing is just software based in Windows. You seem to have a hardware problem and so flashing can't help.

Thanks @coopervid, I guess I was keeping the possibility that the drive wouldn't do anything if the firmware was corrupted somehow, but I'll keep going on my diagnostics and hopefully just find a bad component that needs replacing. All i want to hear is that "usb device recognized" sound in windows when i plug it in, then, hopefully I can get it back together again, these slot load drives are quite complex in their mechanical action!
