https://sourceforge.net/projects/wxhexeditor/
a free hex editor / disk editor for Linux, Windows and MacOSX. wxHexEditor is not an ordinary hex editor, but could work as low level disk editor too.
If you have problems with your HDD or partition, you can recover your data from HDD or from partition via editing sectors in raw hex.
You can edit your partition tables or you could recover files from File System by hand with help of wxHexEditor.
Or you might want to analyze your big binary files, partitions, devices... If you need a good reverse engineer tool like a good hex editor, you welcome.
wxHexEditor could edit HDD/SDD disk devices or partitions in raw up to exabyte sizes.
I was looking for a FOSS hexeditor to verify wiped flashdrives for future sale. Can this be made into an official portableapp,

It is not practical to edit most modern disk formats by hand. Files on them, sure, so long as you know that there is a layer between what you think you are doing and what happens on the disk. Editing the actual data on the drive as we used to do in the 1980's and previously, not practical, just think of the search time on a raw drive between 1981 and today?
Anyhow, back to what you said you wanted. Is it the verification of wiping that you want or a better wiper in the first place, I wonder? There is some tricky stuff going on here, for example, if a drive has marked part of itself as bad and that part of it contained data before, how are you planning to check that it has been wiped? Presuming you reset the table of good 'n' bad what if you still can't read the bits marked as bad? Do you know they are wiped? Answer, no. And so on.

The excerpt from above was copy and pasted from their site, those are not my words. I just tried to give some insight to what the software can do. See, I already use linux utilities to wipe and inspect drives. One of them being this same tool and hexedit CLI tool, and I was hoping this could be made as a portable app for the windows side of things. As far as a better wiping tool I have enough, from DBAN, Shred, DD, CCleaner etc... I just wanted something I can load the disk into and verify that the last wipe pattern of all 0's is present.
Hex editors are really crucial. We have been using them for 20 years now. Here are some things we use them for:
* Deep partition ops.
* Learning computer science, esp data structures
* Writing and porting drivers for Linux
* Studying BLOBs and creating LineageOS custom ROMs for Android phones
* Emulating old games with dead consoles,
* Pattern recognition before decompiling dead online flash games in order to make offline full-screen AI remasters,
* Hacking and penetration tests, ...
I still use Hex Workshop on Windows. wxHexEditor v0.24 Beta was released in 2018 holidays with portable mode support. but portableapps version is still not here and other Hex editors are not good
