I don't think it bothers with anything like block >forwarding or write levelling... Both would be trivial to add. I don't think M-systems considers their FTL any less a company secret than before. I have the source here because of the DOC2000 driver (which I have promised to do a (binary) release of this weekend if at all possible.) Designing and implementing a FTL isn't hard, but it would be much smarter to teack LFS the few remaining ropes, since a flash-aware filesystem can achive much higher performance than a FTL trying to look like a disk. -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
