Well that could work, but only if you backed up your RDB..
I remember, that for some time I used damaged Caviar, that didn't work with a PC, and did work fine with my Ami - it had a bad block on sect 0, PC couldn't write the MBR on it, and on my Ami I moved RDB on some other sector, same way you make an AMI/PC hdd hybrid, and it worked..
