Also see my detailed instructions for cutting the cable (never a good idea to cut the pins on the drive, cables are much easier to replace):

If you cut the wrong pins that could account for the slow access. You also need the proper 400K formatted disks and the correct software with the correct interleave. If I understood on the brilliant Sunder site, the Lisa software used a different interleave than the Mac software. Make sure you read the LisaFAQ thoroughly when creating your disks.
