I have worked with 5 different LTO tapes versions, 5 different other cassette formats (DAT, DDS, etc), and open spools… never, ever, ever in the 15 years had ANY problem (I’ve probably used 1000 of them). We did cycle them very often, we did have proper maintenance of the drives, through. Now that, compared with RAID Disk arrays, where we had monthly failures, was much better. Also I would not trust the „semi-permanent“ NVMEs, where after 1 year without power they get basically reset

When I hear wildly differing stories like this I often wonder how much environmental conditions play a factor in the different experiences that people have.

Perhaps one of you is living in a much more humid and/or hot environment that causes issues with the writing process.

		Tapes were constantly kept in the data center, so constant temperature and humidity 25C/50%. As I said, Tapes were changed after N uses, drives properly serviced. So if you leave them at home, in the sun in summer and in winter expose them to 10C with humidity from 10% to 90%, old drives, never clean heads… IdK That all being said, when I started working there, in my ignorance, I said “TAPES?!?! They are not reliable” due to my experience with audio tapes. But I was laughed at, and they told me about people putting 10 9 track spools in a car [0] (by the way, the same we used for billing backups!) and they went literally thousands of miles driving on partially dirt roads, in summer w/o AC, doing updates to systems, and also never ever had an issue. They were so sure they would work, that they did not take a second set, even when driving 1000 miles, and a read error would mean going back!!! [0] https://en.wikipedia.org/wiki/9-track_tape

		I suppose there could potentially be magnetic factors at play as well.
