MPC 1000 corrupted files,no access to internal drive

Hello,so I have lot of years MPC1000 with no problem.
Today i try to tranfer some drumkits.after that when i try to go to LOAD to load them all file names was tottaly corrupted, ''#^#^%#@^)%&%.^$%'' .this s an example.

Then i check the files that i tranfer folder had an .jpg file,maybe this was the problem?
besides that now that i am trying to accesss from computer via usb i cannot,in order to delete the files that i last tranfer.

does anyone have any solution on that from his experience?
thank you!

it was inside the folder with .wav files that i try to transfer.
i suppose you can transfer whatever files as long pc recognises mpc1000 as a hard drive.
