In any case you're more of a maven than I am! I've been fiddling around with DiskX lately to get rid of file/disk corruption that results when you reboot in the middle of disk writing, and I was fairly successful. But most of what I learned came from brute force/trial and error, and there's GOT to be a better way! Can you recommend a book or magazine article or text file on CIS that explains the ins and outs of the FFS? Also, could you explain how to find out at which key the file header block list is continued? Thanks in advance for your help, – Roger
