Thanks, but there is another issue: i put THEC64-drive8.d64 in same USB stick, no loading from BASIC. Idea?
Something's gone wrong with that stick. Reformat it (fat32!), or use other usb stick /sd card.
edit: you are aware of Windows nasty habit of hiding "known extensions", do you? There is also reversed process: Sometimes when you save/rename e.g. "something.d64", Windows make of it "something.d64.d64". Just disable hiding of known extensions (not just because of Mini).
GParted, exclusively for a year now. I'm avoiding everything related to Windoze, now for years. I bought Win10 Pro few years ago, now I didn't turn that PC for months. Hate those updates, crippleware etc.
The windows application Disk Management i saw two parations GPT and FAT32 (Used by iMac). I reformat it, but GPT won't away. I kept forcing format all (eg. SD Card format) and now it contains one paration FAT32. It can be working for THEC64Mini. Thanks for tip, qurce!
