Out of the box, disk tools won't recognize the device as a valid Apple drive, and won't work. You'll need the "hacked" version, or alternatively you can setup the SCSI2SD to appear as a valid Apple drive by plugging it in via USB to a current Windows/Linux/OSX machine and using the configuration tool located here.
dougg3 details the process here, which I have quoted below.

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:
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).
- 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)
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.
