Doubt mdisc dvd burned

[cloudff7]

1) I Using cdburnerxp I burned a DVD mdisc on a Lite-On iHAS122-14 FU drive (currently firmware EL06) that previously burned and read DVD mdiscs. After burning, the burning test (if the burning was completed successfully) failed. Now, on that same drive, if I put the disc in, nothing appears. I put the disc in an old ASUS drive of my friend and it loaded without any files. I put the disc in my ASUS 24x Drw-24f1mt drive and the files appeared, but only some of them could be extracted because during the extraction it crashes. Is this behavior normal for a poorly burned DVD mdisc? It is very strange that cdburnerxp shows recording completed, fails the test after recording and the files do not appear on some drives.

2) All my other recordings with other mdisc DVDs and the test after burning were completed well but using the ASUS 24x Drw-24f1mt drive.
