Well, couldn't we just as well say "if you use pre-cambrian disks please stick with the 3.X release branch" ? There are many indicies which support killing the wd.c driver: New hardware is supported (much) better by ata driver The ATAPI stuff in wd.c is a rather crude hack, ata driver handles it better. Wd.c is the only driver which keeps the BAD144 code alive in our tree, and nobody uses it. Modern drives do their own bad sector handling. The kind of hardware it supports which the ata doesn't is usually found in machines with less than 32Mbyte of RAM anyway, running 4.0 on such a machine is not even close to fun. (And modern motherboards/bioses seem to have lost the ability to handle old disks, at least the ones I tried here in my lab.) There is a long time until 5.0 which is our next chance. so, speak now, or forever bite your tongue... -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
