Question Question DVD Sata drive and mdisc dvd

[cloudff7ps1]

Is it normal for a badly recorded DVD mdisc on the Lite-On iHAS122-14 FU drive (currently firmware EL06) that it was recorded to no longer be recognized after recording, on another ASUS drive from 2016/2017 to be recognized as an empty disc and on the more modern ASUS 24x Drw-24f1mt DVD drive it to be recognized and the files that were recorded on that DVD m-disc to be shown appears files?

A "badly recorded DVD" may well not show up properly on a different optical drive.
Not unusual at all.

Would it be correct for it not to be recognized by the 3 drives?

Possible, yes.

Why is there a difference in reading between the 3 drives and why did the drive that burned the mdisc not recognize the disc after burning?

I'm guessing "badly recorded DVD" is the problem here.

1. Is it normal or abnormal for two MDisc DVD drives to be burned in the same drive using CDBurnerXP? The first disc burns and verifies in total 21 minutes. The second disc burns and verifies in total 27 minutes? 4x speed two discs

2. If the DVD SATA drive disconnects and immediately reconnects to the PC during the burning or Verify phase, will any error message be displayed by CDBurnerXP?

3. Is it normal for some DVDs to automatically open the Windows Explorer folder with the files when inserted into the drive, and for other discs, do you need to go to the D: drive and click to open the files?

4. Is it normal or abnormal for a badly burned MDisc DVD to not be recognized by the drive that burned it, but to be recognized as a blank disc by another drive, and to be recognized and show the files that were burned by a third DVD drive?

The iHAS122-14 FU is shown as Unavailable on my local Amazon web site. How old is the drive?

The DRW-24f1MT is still available so presumably newer?

As for the nameless 2016/2017 drive, the laser head might be starting to fail.

I have a large number of optical drives, ranging from SCSI 2x CD Writers to three Blu-ray writers. Most of them "work", some of them don't.

When my drives produce optical disks that play back in unimportant applications, e.g. audio CDs for the car, DVD movies, or 4K home video burned to 25GB Blu-ray, I'm happy.

I no longer use optical media for backups and I've never bought M-disc. Is the claimed life of 1000 years for M-disc true? I don't know. It might be if you have a brand new, fully working, calibrated drive with ideal pefectly manufacturered discs.

I've been using Verbatim branded discs for some time. Modern Verbatim discs are manufactured by CMC Magnetics Corporation, but prior to the 2019 takeover, Verbatim was manufactured by Mitsubishi Chemical. Different manufacturers, different dyes, different errors.

This makes interesting reading. If true, Verbatim branded Blu-ray M-discs are now ordinary Blu-ray.

Buying optical media is fraught with difficulties. It's often difficult to know who manufactured the discs until you open the pack and read the information. The name printed on the label often differs from the true manufacturer. It's just branding, like beer. The name may be foreign but the beer was brewed locally.

Should you buy Organic Dye or Inoganic Dye. If Blu-ray, do you need LTH or HTL. What name is on the packaging, Sony, Ritek, Verbatim, Maxell?

What media do you buy?

What software do you use to check for a good burn? I use Nero Burning Rom to create disks and select "Verify Written disc" and "SecurDisc Surface Scan" at the end of the write session.

If you need to check afterwards, there are utilties:

Is it normal for a badly recorded DVD mdisc ....

Yes it's perfectly normal. You have a mix of drives, some quite old, you've got discs with errors and goodness knows what else going wrong. It's a recipe for disaster if any of your discs are intended as data backups, as opposed to audio or movie discs where a few minor errors are acceptable and hidden during playback.

I buy a new optical drive every two years. I don't trust really old drives any further than I can throw them.
