Hacking Unable to format SD card with guiformat

AshleyCummings · May 31, 2021

The closing the Explorer.exe fix did the trick THANK YOU!!

I had the same issue. My solution:

The SD Card was formatted as eXfat. So what I did is that I first formatted the card to NTFS
After that I could format to Fat32. App. you can't format from eXfat to FAT32 directly.

I have that problem all the time. Make sure ALL your Windows explorers windows are closed and try it again. That fixes it for me.

Bingo! Thanks for the share! I feel dumb, since I've had AND fixed this exact problem w/ my Wii already.. (life on repeat)

I come from 5 years in the future to say this worked for me.

Thanks for this thread! I'm curious; they suggest a 32KB or 64KB cluster size for microSD cards going into MemoryStick PRO Duo adapters going into a PSP, but the lowest allocation size guiformat gives me is 512. Anybody know why this is?

Fat32?

Fat32?

Yeah the directions for microSD being used in PSP call for 32KB or 64KB cluster size and FAT32 for high-capacity cards like the 128GB I have.

Hello,

Whenever I attempt to format the SD card with guiformat, I get the error below:

Error:
Failed to open device
GetLastError()=32
The process cannot access the file because it is being used by another process.

Screenshot:

SD card: SanDisk 128GB Ultra SDXC UHS-I (not MicroSD)

I've already tried a few things but still get the same error:

Format at 64KB

Format at 32KB

Start in Safemode and Format

Tested in another computer with an integrated SD card reader

Tested with a SD to USB adapter (it's a no name brand but should work as I've used it in the past).

Some side notes:

The card is readable and I can write to it.

I tested using Windows to format and it was able to format without issues (in exFAT)

Currently in process of using H2testw to check authenticity of the card. Will post results once complete.

Update: H2testw completed and looks like the card is real.

Any help is appreciated! Thanks in advance!

Update:
I found the solution to this. Hope this helps people with the same issues.

1. Open guiformat. Leave it open.
2. Open up Task Manager (either with CTRL+ALT+DEL or right clicking on Start Menu bar > Task Manager)
2. Go to processes tab and look for explorer.exe (for Windows 10, it's simply called "Windows Explorer")
3. End explorer.exe (or "Windows Explorer). You will lose your start menu and all currently opened Windows Explorer windows. Keep Task Manager open.
4. Begin the format process with guiformat and you should be able to format without getting that error.
5. In Task Manager, go to File > New Task
6. Type in "explorer.exe", hit OK. It will bring back your start menu. That's it.

Alternate and quite possibly an easier solution:

Thanks, this worked. Strange that Explorer keeping the SDXC active despite nothing being done to it.

Thank you for this post! I tried the NTFS followed by FAT32 method and it worked for me.
