We have now checked reading and writing of data and audio,but only for standard size discs. Since these discs caused problems at 24x before, I decided to use 16x speed. Now, 99 minutes DataTrack media will be used. Read the full ATIP here. Although the ATIP says "Plasmon", the true manufacturer of these discs is "EuroDigital. Disc"

Writing with Nero Burning Rom doesn't look very promising:

Nero says that burning failed, but the write error occured during the leadout, so that it does not matter at all. It just means that it is not recommended to overburn these very discs further than 99 minutes. When reading back the disc, something weird happened:

At first, the disc was read in a LTR-48125W:

So the disc has been written properly. Reading in the LTR-52246S did not look that well, neither at 52x nor at 48x:

As one more test, I've read the disc in a Toshiba SD-M1502. This drive is not certified for reading 99 minutes discs, and low quality discs of this size, such as Digital Storage Technology - discs, are not even recognised. The Toshiba drive reads the entire disc without any issue, besides an incredibly high access time.

Thus, LTR-52246S not properly reading the disc is definitely a reading issue with the drive (not a writing issue), which can and should be fixed with a firmware update.

After having done all tests, let's come to a conclusion...
