After running in recording mode through Victoria and afterwards reformatting, I saw no blockage issues. Took another thorough reading assessment in HD Tune. In a nutshell, initial write/read speeds of 220-230 mb/s gradually decrease to final speeds of 105-110 mb/s. The CDs shipped with SN04 firmware already installed, as shown on the label. After reading the instructions on the fedoseyev website (just search for "ST6000NM0115 firmware ate"), I was able to successfully ate it to SN05. While testing the SN04 and SN05 firmwares, I did not notice any whistles. The level of crackling is about average for a disc of this type. After three hours of continuous testing, my temperature reached 45 degrees (the disk was on top of the case), according to the smart one, and 51 degrees (the other) (the previous owner had them on the server in a RAID array). The tests showed that the quality of the disks was excellent. If you look at the accompanying tests, I think you'll be able to get a good idea of the quality.
