When I was first using the SCSI2SD, the config utility was a command line program that you ran with the "--apple" command line option to tell it to set the strings correctly for emulating an Apple drive. It looks like that option is now gone with the new GUI utility

What that option did:

• Set the vendor to the string " SEAGATE" (yes, there is a single space in front of SEAGATE for a total of 8 characters)
• Set the product ID to the string "          ST225N" (10 spaces in front for a total of 16 characters)
• Set the revision to the string "1.0 " (with a space after, for a total of 4 characters)

There's also a special Apple Computer string that the drive knows how to respond with, but you don't need to configure it. So all this change does is make it appear as a Seagate drive that Apple HD SC Setup knows about (which is also needed).

Note that if you use the default formatting options, it will only create a 20 MB partition because Apple HD SC Setup's internal drive database thinks it's only a 20 MB drive. So you need to go into the partitioning options and tell it how to use the full space of the drive.
