Any updates on this? I am having the exact same problem and have been trying every solution possible. Heading to discord now
could be broken reader but then it would not be card specific, else the controller might be failing, a lot of shtty disk have this.
If it is for every disk you prolly have some obvious shortout from forcing a card the wrong way into the reader. That would mean physical reconstruction with some tweezers to make them work again.
If it is a broken drive and data matters you can still sand down top and solder 4 wires to databus and extract data that way. Even if the controller is gone with working databus if you have all 4 it is fast if you need to do it with less it will take a bit of extra time but usually you will be able to clone a drive.
