yes, but SFS 1.210 PPC and SFS 1.254 68K (and most likely OS4
) is not compatible anymore.... I had/have the same problem with a SCSI Harddrive (unfortunately I can't downgrade the SFS on the SCSI harddrive since the A1200 died on me).
just thinking out loud here...
the only reason for it not to work is if the 1.254 is trying to be used instead of 1.210 PPC, and the 1.254 has some kind of anti-mos thingy in it, this is because there is no know real differences between 1.252 and 1.254 that should be able to break support in this way.
