Could you try selecting multiple gamesaves (at least 5/6) with the X button and copy them all in a once? After that, select them all and delete. I made a 8mb VMC with OPL 1319 by @Algol - I firstly enabled write operation in OPL settings to see if it would make any difference (I didn't enabled it before 'cause I was making a VMC with the ID default name, so there was no need to enable write operation…). - I powered-off the Ps2, then powered on, entered Wle, mounted the VMC (as VMC 1) and copied a gamesave from the 64mb MC. All fine. Then I copied another save, still fine. Then I copied 4 gamesaves in a once, no problems yet. In the end I selected them all, pressed R1, delete, and the Ps2 freezed when deleting the fourth gamesave. It seems a little randomic. Actually I Always had some freeze problems when copying gamesaves but using other devices it happens very rarely, almost never (even copying hundred of gamesaves at once). Copying on iHDD mounted VMC instead it happens every time, unless I copy/delete just one save at a time. Since it happens with every Ule/Wle versions I'm starting to think that my Ps2 could be the problem.
