[QUOTE=SEBAW;1473814]Attention. I noticed that the drive is very sensitive to a poorly planted disk on the tray. If the carrier is caught unevenly by three paws, the drive goes crazy and does not read the disc. Then you should pull down the plate and back it on the tray, but with stronger force.
First I thought the drive would go to the return, but I was reminded of one comment related to this problem.
Does anyone know what equipment is hidden under this model?[ /QUOTE]
For the base model (without Blu-ray) inside there is a HL-DT-ST GUD1N drive with ROM version 1.00. It is a slim version of optical drive, connected via the USB-C controller bridge to mini SATA, based on the Via Labs VL716 chip (USB 3.2 gen 1 on SATA). Although the connector is USB-C, the VL716 does not support Power Delivery (PD), which is why some systems - especially the USB-C Thunderbolt ports on Apple Silicon computers - have problems with device detection. Using USB-A ports or hubs solves this problem. I managed to get the ODD drive ROM firmware and drop the VL716 memory - I can share them if necessary.
