Description Andreas Klemm 2000-02-24 09:10:01 UTC

After installing FreeBSD 2000-02-20 SNAP (self made snap) on my new 
Maxtor 40 GB EIDE disk, I get the following syslog messages, when 
mounting the partitions of the EIDE disk on my "old" SCSI based system,
which is also a -current of that date

Here a tabular which displays the size mismatch between
syslog message and disklabel sizes. Sometimes disklabel
sector size is equal, more and less...

Fix: 

no fix known

Bruce assumed, that I mount the fresh installed drive with
the old wd driver under my "old" scsi based system.
But this is not the case.

after installing win98 with different partition size 
everything went well don't know why now ....
