Micropolis specs default to 36 sec/track via the settings for W2, W3, W4 on the 1558 drive. If you have a drive that only does 35 s/t or a bios limit leave it out. Doing so gave me 322.73MB .vs. 313.77MB, a gain of almost 9MB. Not jumpering W8 causes the W1007 to force the drive to 35 sec/track ignoring the drive's sector size jumpers. If I said to jumper W14 (Translation mode) out, it was a typo. > > I used WDFMT.EXE from www.wdc.com to format the drive with 15 heads, > 1224 cyls and 35 sect/track (Steve used 36). > > bad144, disklabel and friends were now happily doing their job. > > It looks like we need a section 'ESDI installations' in the FreeBSD handbook. > I'm willing to write that as soon as I understand what is going on exactly. > > How are people using non-WD1007 adapters doing?
