Hi all, first-time poster and all-around *bsd newbie. At one point I 
remember finding a searchable archive but ISTG I can't find it now 
(maybe it was Google?).

I've had no problem installing 1.4.3 on 2 IIcxs. I'm bringing them up 
identically, which helps me to triangulate on any problems. But I 
think I have bad blocks on the one's SCSI drive. At boot I get a 
non-fatal media error, but when I'm going through the pkgsrc stuff to 
fill the system out, I get enough media errors to kill the whole 
process. The OS of course never dies, which is nice. fsck_ffs does 
not fix the cause of the media errors (there are media errors while 
trying to fix it!).

So I reinitialized the whole drive as Mac OS and used Techtool's 
media scan, which found bad blocks. It maps them out, but I think 
that may be a volume bitmap thing that is wiped out on this drive 
when I reinitialize it to a mac partition and a couple of bsd 
partitions. IOW, the problem returns somewhere when I go through the 
bsd install procedure.

BTW, I am using the sbc kernel, and everything works without error on 
the other IIcx. I've checked SCSI termination too.

With all that as background, what I'm really looking to do is use a 
bsd utility to map out the bad blocks. I note that the MacOS Mkfs 
program seems to have no such capability. And I find in the initial 
installation, there is no mkfs in bsd? (I come from Linux, I'm pretty 
green with bsd). What would I use to do this in bsd?

My idea is to mount the bad hard drive as another disk on the good 
IIcx, map out the bad blocks while in bsd, and continue. Any other 
suggestions welcomed. I may junk the drive in the end, but I'm 
interested now in just going thru the process for the education.
