How to delete files from SSD

Hello BMD,
currently I am testing the beta version of BM-Camera 6.0 on my URSA mini pro. The recording takes place on Sony SSD GRAW series. Now I have tried to delete the stored files after transfer to a hard drive from the SSD. Unfortunately it did not work. Windows displays it as deleted, but when I put the SSD back in the recorder, the files are suddenly back and no longer erasable. Unless I format the SSD again. Is there another way to delete the files without formatting the SSD?
Best regards
TK

Formatting is the only way- it's to prevent write errors.

Why do you not want to format the drive?

Thank you Sean and Michael. I was worried that constant formatting could harm the SSD's.

So each time you write (but not read) a SSD drive it causes a little bit of wear on the memory cells. That sounds bad, but it's not. It's a very predictable process. Different types of memory have different life of read cycles, but even the shortest is measured in the thousands. That may not seem like much, but even if you fill the drive from empty to full, then erase/format it every single day, seven days a week, that give a minimum life of 5-10 years, depending on the memory. And that's a brutal use case.

So in theory SSD life is worth keeping in mind, but for 99.9% of real world use cases it's never going to be the limiting factor.

Note, formatting the SSD doesn't write data over the entire drive. In simple terms, it deletes the list of where to find the files on the drive.

Correct - this allows the drive access to overwrite the locations. It's also why you can *sometimes recover data from a drive that's been formatted but not overwritten.

Years ago when I was learning about SSD technology on AnandTech or TomsHardware, I recall reading that the SSD data controller in a Write operation must first write binary zeros to the block and then write the real information to be retained. This of course is in contrast to spinning hard disks that just write regardless of the state of the block.

I don’t know if this is still true as I have no time anymore to learn anything being retired (the busiest time of your life)!
