Default [Q] How to fix "Error mounting /data" in CWM on Sprint HTC One M7

Hello as the title reads, I keep getting "Error mounting /data" in ClockworkMod Recovery v6.0.4.3. I've been googleing and searching xda for two days now and have not found a solution that works. I really need my phone back so any help would be greatly appreciated.

I cant wipe data, flash any new roms, or run RUU. I was happily rooted and running custom roms on my old M7 for almost a year but this one has me stumped.

Thanks in advance,
-Daniel
