I cannot capitalize file names in a new portable SSD device

I just got this Crucial X6 2Tb Portable SSD 2 days ago.
I already copy over a Tb worth of files, mostly JPGs, PNGs, and MP3s.
Other than the slow copying - 40Mb/s, about 12 hours - I have noticed that I cannot capitalize the file names of my MP3 files. I have tried other types of files, PDF, HTM, and Txt, the same result. I have tried this in Windows 10, Windows 11, and Linux (Pop!OS), to no avail. I also tried renamer utilities, including but not limited to, the one included in the MS PowerToys.
Only if I change a complete word it works.
Any ideas?

Thank you guys!

What is the file system on the drive ?

exFAT

Is that the reason?
Should I change it to NTFS?

Convert it to NTFS it will fix your problem and is a more robust file system.

Code:

CONVERT driveletter: /FS:NTFS

Are you saying that I can just enter this command line in the Command Prompt terminal window without having to erase everything first with a partition file manager like Gparted?

Looks like I'll have to format the drive first... The following information is from MS Copilot:

"No, you cannot use the `CONVERT` command to change the file system of an external drive from exFAT to NTFS without deleting its files first. The `CONVERT` command only works for FAT32 and FAT16 file systems¹. If you try to use it on an exFAT drive, you will get an error message saying: `CONVERT is not available for EXFAT drives`².

I hope this helps. Please let me know if you have any other questions. ��"

There was more information explaining 3 choices to format the drive, but for some reason that information was triggering a security system in this website blocking me right away. But you already know how to format a drive in Windows anyway.

@MaloK, thank you for putting me in the right path
