If you can attach the drive to an RT and get a copy of the VRM Installation
Diskettes (normally used with AIX) you can probably fix the disk.  

Put the diskette in the floppy drive, the power up the RT.  Select
the option to enter the Maintenance Facility.  The(You may be asked
to choose a keyboard language first, but don't worry  --  you'll quit
without installing a VRM.  Then  choose the format
disk option.  (? get's help).  This utility will enable you to rewrite
the configuration record, then format the disk.  You can pick
the format from several canned configurations.  Make sure you have a new
VRM diskette that supports the 310M drive.  Good luck -- I've only done
this with 70M disks.
