Recently I noticed a really strange “side effect” on drives when I install them on an external box. Disc quality, both in burning and in reading, deteriorate badly.
Actually I don’t know if this behaviour is due to a software or a hardware issue, but because of I noticed it with different drives in the same external box it seems to me a hardware problem, so I posted here in hardware forum.
The box I’m using is this one. It have a NEC chipset (sorry, I don’t have a camera, so I can’t take a pic of the chip )
The following are some examples of this strange behaviour. This disc was burned @12x with a Samsung SH-S182D firmware SB04. The first pic is a scan done with liteon 1693 in the external box, the second is a scan of the same disc with the 1693 installed internally. The third pic is a scan done with a Sony 120 installed internally, just to have a comparison.
The last pic is a TRT.
I wonder if it’s only me or someone have this same quality worsening when the drive is installed on a box.
