Display summary of procedures, with confirmation, before exec

[edbird]

When selection options (method/verify/blanking) before run, it is not clear which of these options are actually exec'd.

Example:

Set drive to wipe. Change method to zero fill/quick erase. Select V, verify last pass. Select B. "Perform final blanking pass is selected by default. Wut? Why? Does this mean that after selecting quick erase mode, that another quick erase is done after the first quick erase?

I change it to "do not perform final blanking pass".

Go back to "V". It now defaults to "Verification Off".

That's not what I want.

I want to run a single (not two) zero fill pass (erase) on my drive, then verify that it is "zero'd".

How to do? Looks like this cannot be done because changing one option changed another.

Hence why I request a summary of actions to be performed so I can understand what it is actually "set to do" before running.

Btw... all these options suggest some sort of command line option can be used, but there is no info in man pages about how to use in command line mode. It just says, that "no gui" mode can only be used with autonuke, which is clearly not what I want, I don't want to nuke my server.

2'nd btw: This is for an SSD drive. I don't know if this makes any difference. (Regarding writing zeros/SSD trim?)

Further to this issue... This is what is shown on screen after doing the following

Load program
Select M = method
Change to zero fill
Shift + S = start
You can see that it says:

(Top left): Rounds: 1 (plus blanking pass)
which implies that 2 rounds are done. 1 round of the method (zero fill) and then another blanking pass.

I don't think this is what the program does, because as you can see below it says

round 1 of 1, pass 1 of 1, and it states the progress is 50 % ish
but then again I don't know for sure.

Basically it is confusing. I don't know if it does a final blanking pass or not. It doesn't seem to correspond to what is selected in the settings before running in some cases

Yes, you're correct. For a zero fill it's confusing. Although it says on screen it's doing a blanking pass I don't think it does (as it's not necessary as it's already done a zero fill which is the same as a blanking pass).

Basically for zero fill the blanking pass shown in the GUI needs to be removed for zero fill when verify is switched on.

I'll allocate the fix to myself.

I also find that the presentation could be improved regarding the Final Blanking Pass.
When I do a PRNG stream, for example 2 rounds with a Final Blanking Pass, here what's written during the final blanking :
[70.23%, round 2 of 2, pass 1 of 1] [blanking]
In this case, wouldn't it be clearer to have ? :
[70.23%, Final Blanking Pass] [blanking]

I also noted a problem between options when doing a PRNG stream wipe, with for example 2 rounds.

When I choose not to have any Final Blanking Pass at all, Nwipe changes the verify parameter from "Verify All Passes" (which I have chosen) to "Verification Off".
If I change back the verify parameter to "Verify all passes" or "Verify Last Pass", the blanking option resets automatically to "plus blanking pass"

(I am using nwipe 0.29.006)

Set drive to wipe. Change method to zero fill/quick erase. Select V, verify last pass. Select B. "Perform final blanking pass is selected by default. Wut? Why? Does this mean that after selecting quick erase mode, that another quick erase is done after the first quick erase?
