Macintosh Error - 43

Hello

I am getting this error when i try to edit a song in Peak Pro. It just started last night. When i try to cut a piece of my song out it says " Macintosh Error 43, file not found. Creating Temporary file.???

Then when i hit ok it says " Peak was unable to create the required disk file for this clipboard operation. There may not be enough disk space available".

I have plenty of disk space left??? from what i was reading my hard drive could be corrupt??

I dont know if it is the program or my hard disk?? What is ERROR 43??

any suggestions would be great!!

Thanks
