Format Large SD Card for Android

I’ve got several older devices laying around that I use for various things (media players, cameras, etc.).  Recently I tried to upgrade the Micro SD card in my HTC Droid Incredible (ADR6300) running Android 2.3.4 from 8GB to 128GB and I had a heck of a time getting it to recognize the 128GB card.

Formatting via Windows for anything over 32GB can’t be done using Disk Tools (you can only format as exFat and NTFS).  Thus, if you’re going to format with what you’ve got in Windows, you have to use a command line.  Using the “quick” format command in the command line ( format <drive letter>: /FS:FAT32 /Q) almost always causes failure for disks over 32GB, and when you don’t do a quick format, it almost always pretends like it’s formatting for a couple of hours, then fails.

I actually got the Droid to recognize and format the card using its own utility at one point, but then the phone just went into boot loop and finally hung on the HTC screen.

I am loathe to download and install programs from weird locations around the web, but after about an hour and a half of trying all the routes that DIDN’T involve installing software, I finally broke down and installed FAT32Format from Ridgecrop Consultants, LTD (a guy in the UK).

Here is their fancy logo.

While their graphic design may leave something to be desired, their code rocks.

Lemme tell you… I wasted a lot of time trying to figure out “other ways” when I could have just done this in the first place.  The executable is tiny (76KB), and the disk was formatted and working in my droid in less than 60 seconds.

Kudos, Ridgeway.
