I recently added a SCSI ZIP drive to my FreeBSD system. I've taken a stab
at at putting a file system on one of the disks. The following steps will
place a file system on the disk.
* scsiformat sd2
- Takes about 7 to 9 minutes to format
* disklabel -w -r sd2 zipdisk
- The following entry is in my /etc/disktab. I've forgotten who
posted this to the mail list.
zipdisk|100 MB ZIP disk:\
:ty=removeable:dt=SCSI:\
:se#512:nt#64:ns#32:nc#96:\
:pa#196576:oa#0:ta=4.2BSD:\
:pc#196576:oc#0:
* newfs /dev/rsd2c
* mount /dev/sd2c /mnt
This is all well and good. It works nicely but I have two problems: the
first is when I mount the disk I get the following on my xconsole
sd2(ahc0:5:0): UNIT ATTENTION asc:28,0
sd2(ahc0:5:0): Not ready to ready transition, medium may have changed
sd2(ahc0:5:0): ILLEGAL REQUEST asc:24,0 Invalid field in CDB
sd2 could not mode sense (4). Using ficticious geometry
sd2: invalid primary partition table: no magic
sd2: raw partition size != slice size
sd2: start 0, end 196607, size 196608
sd2c: start 0, end 196575, size 196576
the other problem is
superior# df .
Filesystem 1024-blocks Used Avail Capacity Mounted on
/dev/sd2c 95343 1 87715 0% /mnt
superior#
It's bad enough that you don't get 100 meg that you would think but where
did the other 7.6 meg go to ? I understand that some gets lost in laying
out the UNIX file system but this does seem exessive. I'm sure I doing
something wrong, any ideas ?
