Problem accessing HFS

["Joel Carnat" <joel%carnat.net@localhost>]

Hello,

I was going to upgrade my mini from 4.99.72 to netbsd-5.
What I planned to do was just copy the new GENERIC kernel to the HFS
partition and reboot, but when I tried to access/copy the HFS partition, I
just ended scratching it :(

The system is still up but I guess I won't ever boot at next reboot.
Here's what my installation look like:
guarana# pdisk /dev/wd0c
Edit /dev/wd0c -
Command (? for help): p

If I look at my notes, what I did last time (from the install CD) is:
* prepare the HFS (boot) partition
 # hformat -l boot /dev/wd0d
 # hmount /dev/wd0d
 # hcopy /usr/mdec/ofwboot.xcf :
 # hcopy /netbsd :
 # humount /dev/wd0d

This is was I tried to do again but I keep getting only "netbsd" when I
issue the hls command...

guarana# hmount /dev/wd0d
Volume name is "boot"

guarana# hcopy :netbsd .
hcopy: ":netbsd": read unallocated block (Input/output error)
guarana# humount /dev/wd0d

I'm using hfsutils-3.2.6nb1.

Any idea how to reinstall the kernel & bootloader on the HFS partition ?

TIA,
