[ ... WD1007 ... ] > BTW for anyone who is interested... > > My drive is an ESDI by micropolis, and i had to insert 14 and remove 8. > (this i know after 2 formats) 1) He got the format utility from ftp.wdc.com; the FAQ should have a full URL. 2) The controller is a WD1007. 3) The default settings for the geometry translation in BSD are *wrong* for the WD1007. The reason he had to jumper off the sector sparing and translation is because: o The BSD translation assumptions are Adaptec assumptions and are *wrong* for the WD1007. So translation has to be off for them to work. o The sector sparing does not cause the drive geometry reported to the controller on "query physical geometry" via the WD controller API to subtract out the sector, so the driver *incorrectly* attempts to access one more cylinder than is legally addressable. If this goes into the FAQ, the *detailed* information on WD1007 jumper settings and their meanings should be pulled from the -hackers list archives (subject containes "WD1007" or "ESDI") and put there too. Someone should contact Western Digital about their format utility to ask if it is OK to mirror it on the FreeBSD FTP site and to put it on the CDROM. There should be a WD1007.DOC/WD1007.README (normal/RR long name) on the CDROM so that this isn't still a problem. Ultimately, the driver should be fixed to sense the WD1007 and handle the jumper settings correctly (for one thing, by not assuming what the translated geometry is without making the BIOS call to really find out).
