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: http://imgur.com/9Vl09CT 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!
