Sunshine,
Thankies. DiskEditor just let you edit some values of the partition table etc. Not what I'm looking for. DiskInvestigator is more like it, although it is very limited in what it can do, and development has halted long time ago. But it is the kind of tool I need, but still more advanced....
I'm currently using some other (not very user friendly) tools, very slow, but hopefully they will do.
If anyone knows a good Disk Editor (like the old PCTOOLS disk editor), please share it
