Richard Levenberg:
|I have a SCSI IoMega ZIP drive. I am trying to put a file system on it and
|am having trouble.
|
|I have an NCR SCSI controller which sees the ZIP and gives the standard
|error that everyone is getting and which I am not worrying about. The
|identification string says IOMEGA ZIP 100 D.08. I formatted the disk in
|WIN95 and booted FreeBSD 3.0-970118-SNAP. Ran FDISK and changed the sysid
|to 165.
|
|I have a disktab entry of:
|
|zip100|Iomega Zip 100: \
| :ty=winchester:dt=SCSI:se#512:nt#64:ns#32:nc#96:rm#3600:\
| :pa#196576:oa#0:ba#4096:fa#512:ta=4.2BSD: \
| :pc#196576:oc#0:
I'm using the same disktab entry on an NCR-SC200 with a SCSI ZIP on
2.2-ALPHA. I don't know enough about disklabel and newfs to know for
certain what's wrong with your procedure, though I'd hazard a guess it's
because you're newfsing on the block and not the character (raw) slice
device. Let me just list what I'm doing that works for me:
I also create my UFSs in compatibility slices, though I put mine on slice 1
instead of slice 4. Here's what I'm using:
| disklabel -w -r /dev/sd0s4 zip100
| ^^<-- this is from fdisk
disklabel -w -B /dev/sd0s1 zip100
| newfs -Tzip100 /dev/sd0s4
newfs -Tzip100 /dev/rsd0s1
If you want to get a little more space for your UFS, you can dedicate the
disk to the UFS (i.e. not work within within compatibility slices). Here's
the procedure posted by Bruce Evens, expanded for use with sd0:
dd if=/dev/zero of=/dev/rsd0 count=2
disklabel /dev/rsd0 | disklabel -B -R -r sd0 /dev/stdin
newfs /dev/rsd0c
mount /dev/sd0c /mnt
