I back-ported the pcscp driver to NetBSD 1.3.2, using the code from -current around 26/1/99. The patch which Izumi Tsutsui (who wrote the pcscp driver) submitted a few days ago (kern/7252) has fixed the problem writing large tape blocks. But even without that patch, the driver appears to work for everything else apart from tape writes > 4 KB. For example, I was able to duplicate my EIDE system disk to a borrowed SCSI drive connected to my Tekram DC-390 and boot and run from it for several hours with no problems whatsoever.
