HP DVD+R DL 8X 10PK cake box HP 8.5GB

These discs are not compatible with the "HL-DT-ST DVDRAM GT20N" burner (I tested three discs; all failed).I was trying to burn the latest Windows 10 Version 20H2 disc image (which is about 4.7GB in size) using the built-in "Windows Disc Image Burner". The first two discs would not even begin the burn process; they just made lots of random noises, and eventually were ejected with an error-message. Then I tried using ImgBurn, and got an error near the start but clicked "Continue" to ignore and the burn did reach 100%, but on putting the disc back in the tray to verify it, it won't stabilise: the drive just endlessly makes lots of random noises.[Update: the discs do work fine in these two drives: "LG BT30N" and "Panasonic UJ260AF"]

Avoid ,Amazon only allow a minimum purchase of three packs..I have used three discs on two different dvd TV recorders..Disc go through the recording process without any problems ,but when you try to finalize the discs ,the finalize fails and the discs corrupt and become useless ... Only used three out of thirty and all three have failed ..Think I've just paid £21 for thirty coasters... Not sure whether to give a couple of them another go ,take the £21 hit or return them ...

good quality

Ease of use computer read the discs instantly. Writing to them was also uneventful.

I've never seen such poor quality discs. Out of 30 so far read errors were on 22 DVDs. If I knew I wouldn't buy them.
