Getting Unknown & Random Characters in Reading Sector

[Amir1387aht2]

Hi everyone, Thanks for Participate

I tried to use this library to read and write strings from Winbond w25q64fv using stm32f030k8c8
but there's a problem, I have a system that check sectors to find if sector is empty or not,
when I try to read the sector, sometimes it returns Unkown characters or random characters that not what i saved
Even If I Erase Sector Completely, It Again Return Same Result
I Use 10cm wires

Does Anyone have Idea How to Fix it?

Thanks
