General :: Scalpel Carver And Skipping Blocks?

I'm working on a ~1 TB disk that was loaded with all kinds of images and documents that lost it's HFS+ partition table. The person for which I'm doing the favor of running scalpel says it's likely there's 90GB of stuff. Somehow, the disk got relabeled/MBR changed to some FAT variant that works on the whole Terrabyte.

Attempts to recover the partition info failed.My first try with scalpel finds more than 90GB of image file headers alone and that blows through all of my storage. Of the headers found and recovered as images, a simple test shows most of the image files are broken. The cluster size option does not work if I use it by itself. It errors out before it gets going.I want to speed things up and skip the countless broken image files.
