Disk Capacity Verification Utility

Opening Notes:

Disklarity, as afforely-mentioned, is a Disk Capacity Verification Utility. It divides the filesystem of a disk into segments based on the advertised size, then reads them.

It was created as I purchased a large amount of MicroSD cards over Christmas, of which I could do to test considering they're not exactly main-branded. I could use Gibson Research's ValiDrive, which would've been my normal go-to, but I decided to write this instead as a personal challenge.

Usage:

Using Disklarity is quite simple.

To begin with, run Python as an Administrator.

Then, run:

disklarity list

this should output similar to the following:

Listing.
Listing Devices...
Found: 'KINGSTON SV300S37A240G' @ \\.\PHYSICALDRIVE0' # Boot Disk
Found: 'KINGSTON SNV2S2000G' @ \\.\PHYSICALDRIVE1' # This is my SSD.
Found: 'Generic- SD/MMC USB Device' @ \\.\PHYSICALDRIVE2' # This is a MicroSD card reader I used for testing.

Note that \\.\PHYSICALDRIVE0 is your Windows drive. No matter your UAC level, Windows will NOT let you verify this drive.

Next, once you've found your device of choice run:

disklarity \\.\PHYSICALDRIVE#

Wherein # is the number at the end of your device's \\.\PHYSICALDRIVE string.

After that, the program should guide you the rest of the way.

Current State & Caveats:

• Runs, and presumably works. (OnMyMachine™)
• Only tested on two devices (Broken MicroSD over-reporting size & random 1MB drive I found.).
• No GUI. Tkinter-based GUI planned.
• Missing thorough fake space checks.

Todo:

• Add afforementioned fake space checks.
• GUI [TKinter / WebView2?]
• Increased configurability
• Simpler Device Selection
• Various Cleanups.

Thank you for your time, and enjoy! (Hopefully.)
