Thanks so much for your help Fiona! I've run photorec and it was able to recover about 500GB of data, which is impressive but far from the 1.5TB I've lost. It also wasn't able to preserve the file names or folder structure :|

Still stuck with this. Any help would be greatly appreciated.

I tried running with "align partition = no" and "partition type = none" but still to no avail. One of my old partitions is recognized and is readable while the other is recognized, but I can't list it's files. Here are some snippets from the log (it is too large to paste and I'm not allowed to ...

Thanks for the tips, remy, I'll try them out tonight. I'm currently running deep analyze with an increased cylinder count per fiona's advice (I randomly guessed 245000). When I change the "align to cylinder boundary" option to "no", should I keep the modified disk geometry or reset it back to the ...
