Partition disappear in OS 3.9

[amiga1260]

I have a Sandisk 8 GB Ultra II in my Amiga 1200 with a Blizzard 1260.

The following partitions were made:

Workbench : 303 MB
WB31 : 26 MB
Games: 3.7 GB
Work : 3.9 GB

When I use Workbench 3.1, I see my Work partition. In OS 3.9 it doesn't show the content.

I already use the setup skipromupdates "scsi.device" and Boing bag 2a.

I thought about it. I deleted the wb 3.1 and made a big Work parition of 7.5 GB.

I removed the skipromupdate from the Setpatch.

After that I installed FFS v43 on the RDB and use HDToolbox of OS3.9 to create the 7.5 GB partition.

finally a format the partition and copy the data back.
