For the last 5-8 years I only use game disks to make images out of them.

That said I have games that are 20 years old and I just keep them in normal boxes as well as jewel cases / paper sleeves and I never had a problem with a single disk going bad in any way.

I do plan to purchase a couple anti moisture gel packets and throw them into my wardrobe and boxes where I store stuff for the ease of mind :p

I wouldn't use the drive anymore to be honest.
Had a similiar case when browsing through family photos on my Samsung SSD drive and discovered a couple corrupted images / videos.

The next day that changed to corrupted folders but thankfully I had everything mirrored on various other drives.

Coincidentally this started after plugging the SSD into a new USB-C enclosure - it was in a USB 3.0 enclosure before. After all that it reported a wear leveling count of 3 but apart from that SMART seems fine. Still not using it for anything important.
