:-( As wonderful as DiskSalv is, it is a little dated. If I understand it correctly, DiskSalv, like Shapeshifter, drives the hardware directly as it works with your drive. Unfortunately, it also uses 32 bit addressing, and signed arithmetic at that. This means that the most significant bit is used to indicate whether the rest represent a negative or positive number. The range is still four billion and change, but it extends from negative two billion to positive two billion, with zero in the middle instead of at the low end.
Any attempt to write above the two gigabyte mark will result in the negative numbers noted above. Sadly, DiskSalv works only on voulmes below the two gigabyte mark.
