Well, my new SCSI2SD arrived today (the new small board), and I have spent the entire evening trying to get it to work with either my SE/30 or Classic II.  At first, neither machine would even recognize it was there until I updated the firmware.  Now, while they can see it, HD SC Setup won't initialize the drive.  I've tried the patched version of 7.5.3, no luck.  Am I missing something in the SCSI2HD setup? Incompatible SD card? I've read enough posts on this device that say it is a relatively pain-free and easy process, but I'm not having any luck at all.
