Go to Add/Update, remove the SmartFileSystem entry, click on Add and select the file (L:SmartFileSystem). Now a window appears where you can overwrite the identifier and version information. Overtype 43465300 by 53465300 and press enter. If you now go back to Change, you should have SFS/00 in the list.
Thanks for the information!
Ok I did this and managed to use SFS/00 but I STILL get the extra partition at the end of this disk which I didn't ask for.
I created DH0, DH1, DH2, DH3 but on the Workbench I see all those but I also get DH1_0 which I didn't configure. Its right and the end of the disk and is 8073mb. The other strange thing is after DH0-DH3 there is :Uninitialised but after DH1_: there are corrupted characters.
Another thing is when I then go back into HDToolBox it displays the extra partition but when I click on it both that partition and DH3 are selected as if they are one partition and not 2. Strange.
Might be some limitation with HDToolBox?
