Floppy drive on mpc2000

hey everybody!!!
my mpc2000 is starting to give me a headache with those "disk error" messages...I guess it´s time to swap my old floppy drive.
Does anybody know, which model I should get??
Is there a particular one??? Or can I just get one off any old computer cpu?
Thanks anyone for having a look at this!!
Easy.

guess it is any floppy disk drive from an old computer with 40 pin connector but might be wrong...
