Dear experts,

I'm using FreeBSD-4.9 RELEASE on two different machines. One with an 
NEC 100MB ATAPI Zip drive and another with an 250MB USB Zip drive.

The 100MB medium can't be exchanged between the two drives when it is 
labled and ufs formatted. The partition and label in the 250 MB USB Zip 
drive works well, but can only be udes as /dev/afd0a on the ATAPI drive.

Partition and newfs on the ATAPI drive only works, when I cut off 32 
sectors of the partition a. Otherwise I get

96904 : disklabel afd0  
# /dev/afd0c:
type: ESDI
disk: afd0s1
label: 
flags:
bytes/sector: 512
sectors/track: 32
tracks/cylinder: 64
sectors/cylinder: 2048
cylinders: 95
sectors/unit: 196576
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0           # milliseconds
track-to-track seek: 0  # milliseconds
drivedata: 0 

8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
  c:   196576        0    unused        0     0         # (Cyl.    0 - 95*)

[EMAIL PROTECTED]:~/
96905 : newfs /dev/afd0c
Warning: Block size restricts cylinders per group to 97.
Warning: 32 sector(s) in last cylinder unallocated
/dev/afd0c:     196576 sectors in 48 cylinders of 1 tracks, 4096 sectors
        96.0MB in 1 cyl groups (97 c/g, 194.00MB/g, 12288 i/g)
super-block backups (for fsck -b #) at:
write error: 196575
newfs: wtfs - writecombine: Input/output error


There seems to be a 32 sector difference induced by the driver, or the 
drive?

Who can help?

Regards

Lars
