How to wipe a phone with corrupted storage

I've got a Sprint Galaxy Note 2 (SPH-L900) with storage issues. For a few months now, the internal storage will occasionally become corrupted to the point where it won't boot. I have to wipe, reformat, and reinstall to get it running again using TWRP. When it died today, I decided it was time to trade up to a newer model. However, when I try to reformat the internal storage as usual, TWRP claims that it can't access the internal storage at all. The regular partitions are all in the list of things on which I could operate, but they're all listed as being not present in the phone. Is there any way around this?

I'd like to sell the Note 2 for whatever I can get for it (with appropriate disclosure, of course), but I'm not about to let it go without convincing myself that my personal data has been completely overwritten. If TWRP can't see the internal storage, how can I reformat it? Might adb or some other computer-based solution have better luck? I've never run that before, except when flashing TWRP with Odin. The phone won't currently boot past the initial black & white "Samsung Galaxy Note II" screen, unless I'm booting into recovery.

FWIW, I've really enjoyed using the MoKee 6.0.1 ROM on this phone recently. It's a pity the phone died out from under it. It has several nerd-friendly features that my wife's stock S5 lacks, and which I'm sure my new Note 4 will also lack.

Have you tried restoring it to factory settings by flashing the factory image/software using Odin? That's probably your best bet.

Unfortunately, that didn't work, either. Neither TWRP nor Odin was able to tell that the phone had any storage available. I suppose it's safe to sell the phone for parts, since nobody else will probably be able to get at my old info, either.

Worse yet, my son's Galaxy S3 (same generation as my Note 2) just died over the weekend with the same problem: is internal storage completely disappeared. His storage apparently exists, but shows up in TWRP as being zero size. Flashing with Odin didn't help him, either. His was bone stock before the problem appeared; I installed TWRP afterward to try to run fsck. I'm getting pretty tired of this.
