Hello everyone, Thank you for your answers
Brad: I have recreated the a partition after the problem I mention. Before doing my manipulations the a partition was exactly the same as the c partitition Jan, yes I was expecting someone's comment about chatgpt and of course before posting I recongnised my mistake. I usually don't follow instructions blindly but I wanted to search some of my data that I couldn't find and I was fed up. This is human nature that make us to want to find shortcurts I don't know what was on this disk so maybe I have backups maybe not. The goal was to find some data and later reorganise them. Thank you all for your answers.
