I have got a big box of about 25 years old CD ROM disks with scanned B/W 70-100 years old photo negatives. I was using copies from HDD for many years but failure of my server resulted in loss of significant part of files. I plan to make another set of copies from original CDs. ...

3/ When I was investigating this issue I came to the conclusion that "M-Disk"s were the best current solution; this involves (a) buying an M-disk capable DVD R/W (most Blue-Ray drives) (b) a supply of M-Disks (25- 100)GB ...

That looks like an excellent suggestion! But...

I tried to check Verbatim, who seems to be closest to the original developer Millenniata. They offer "External Slimline CD/DVD Writer" with notice "Software compatible with Windows operating systems only". That may mean included Nero burning SW only, but even that may be a show stopper - in discussion on another site somebody complained that his attempt to use M-Disk failed (on Win...) and it was suggested that he should use Nero. As Nero is included with Verbatim drive it may indicate that not all burning SW would be compatible.

It would be nice if there would be some experience with using linux for burning of M-Disk.

And I still have to find the best way how to recover data from my old and suspicious CDs... (M-Disk writer may be good enough for that too.)

Oops sorry Petr; 1/  is the need for an "external" (typically USB) CD/DVD drive because it needs to connect to a laptop ?;    mine is an  LG m/n HL-DT-ST BD-RE WH116NS48 internal SATA drive in a desktop;   I had a look to see where I bought it.....no luck, may have been MSY ! 2/ There is a quick explanation of why M-Disks and Blu-Ray disks will last longer here: https://www.pcworld.com/article/2933478/m-disc-optical-media-reviewed-your-d... 3/ Never had a problem with Windblows read-access XP-64bit, 7-64bit, 10-64bit;  usually use BurnAware for burning;  hadn't realised there was a driver issue with Linux. Just now booted PureOS 8.0_gnome-live-20190210_amd64-hybrid iso off that drive and after it had made a few guesses about drivers it finally booted...... -the GUI drive-utility correctly identified the M-disk drive as :  CD/DVD/Blu-Ray drive: "HL-DT-ST BD-RE_WH116N48" -the GUI files-utility correctly recognised a previously burnt M-Dsk as 23GB (of  a 25GB disk) regards Rohan Mcleod
