Migration error from Windows XP

Successfully loaded virtual machine on Mac. Tried 4 times to migrate from Windows hard drive onto external storage device but error message each time half-way through 'disc error'. Is there any way to see where the error is stopping the migration process so I can delete that file as the pvm files which have loaded have a title which is not recognisable? Also ran disc check on Windows machine but showed up OK there.

Thanks
Maggie
