Why are you saying that ImgBurn don't let you? Do you get a write speed miscompare in the log when you select 4x?
Exactly. This message was appearing every time I tried to set 4x speed - since I began using the drive in question. So I simply started setting speed at 6x, as the slowest possible. BUT (it suddenly struck me) I've changed my laptop about a month ago, and since that I never tried setting 4x speed, so I should possibly try. Thank you.
The reason I ask about external drive is that I am using it with laptop PC, where built-in drive is rubbish. The thing is that the drive I used before got burnt for no good reason. It was powered from the mains, and in Ukraine, where I live, voltage drops is a not very common, but still existing problem. and far as I understand, socket powered drive is more vulnerable to these swings, especially in the process of burning.
BlizzardUK, my previous drive was LG) Not sure about internal, this is some stuff that Samsung installs on all their laptops, and, when I tried it, as I mentioned above, it failed finalizing disc. Internal drive on my wife's lappy is working well, but, according to my experience of extensive use of internal notebook drives on various models - it is a matter of time. Thank you for your link.
