Gaming Savegame from old to new HDD

[ComX]

Hi to all...

Now i´m on 4.55, tryed to copy my savegame to USB, but i got an error message.
Don´t know why.
I played these Game on 4.05, save there.. then today i have update my console to 4.55 and load the game..
Everything works fine.. Savegame works too... but now i will change the 500GB to 2TB and copy the savegame to an USB stick before i change the HDD.
But i got an error message.. what to do? anything i´m doing wrong or forgot.?

Thx in before..

Edit: Now i make a Backup from HDD.. Size 335GB.. after i take it back to the new HDD, the Savegames are there too.??
