This is a problem, because we know that cards are going to fail and should be replaced after some time, before they fail, with a careful planning. But we don't :-) I no more own cameras working with CF cards, but at least one of my SDXCs is rather old... and for some time the NEX-6 which uses it complained about not detecting it, then the problem disappeared.
In the past, there was a rapid evolution of standards (e.g. I moved from CF to SDXCs) and later the increase of megapixels demanded new cards (my first SDXC was 4GB, now I only go for 64GB): this forced a turnover. But now I suppose my cameras will stick with SDXCs for a very long time and megapixels aren't increasing any longer (for me, at least), so I should think over it...
Sony a6300, Sony a6000, Sony NEX-6, Sony E 10-18mm F4 OSS, Sony Zeiss Vario-Tessar T* E 16-70mm F4 ZA OSS, Sony FE 70-200mm F4 G OSS, Sigma 150-600mm Æ’/5-6.3 DG OS HSM Contemporary, Samyang 12mm Æ’/2, Sigma 30mm F2.8 DN | A, Meyer Gorlitz Trioplan 100mm Æ’/2.8, Samyang 8mm Æ’/3.5 fish-eye II | Zenit Helios 44-2 58mm Æ’/2 Plus some legacy Nikkor lenses.
I downloaded the photo immediately to see the EXIF in search for the clues about which lens Klaus may be intending to review next. Other than the fact that this was taken with a 5DSR camera and a 100mm lens that doesn't leave a model description in the metadata, I haven't learned much. So... a Zeiss Milvus 100mm Makro-Planar?
Sorry Klaus, that's rude of me. But I've seen similar things happen to a couple of my photos when I was using a computer with (as it turned out later) a faulty RAM module to copy the photos from the card. So while I don't argue that it was a card gone bad in your case - of course you know better what happened to you - in other cases there may be more than one thing causing this effect.
I had this magenta patterns when I got a D7100 first and tried it's 5:4 ration - which then was not supported by Capture One. Same happend with importing compressed Fuji RAW at a time the Capture One developers were hibernating for 1 year and released support for compressed Fuji RAW afterwards. I could have saved some 100 GB without that year of waiting...
