There's often file coruption on the SD card of TRX scanners. It has something to do with its USB interface. I take out the SD card and program in a SD card reader and all issues with programming went away. It's still issues with file corruption but only to recorded audio files.
.ts or TS means trunked systems and it is the 4:th one that have file corruption. Don't remove that system but instead rename it to "Bad" or similar and make a new one to replace the old.
You can't brick the scanner whatever crazy things you try to do. Reformat the SD card and program it from scratch with a new database and it will probably work fine. The SD card that came with my new TRX scanner was dead on arrival and caused at lot of problems for me, being a new scanner working totally different from a Uniden that will take a while to get used to, but that SD card it came with in the box can not be formatted or initialized in any way to make it work again as a memory card.
