The removable disk is not working when booting via WinToUSB. The fixed disk was able to change from Offline to Online. However, the removable disk was not able to change from Offline to Online. It shows gray letters as the screen-capture when I click the right button of the mouse. I've tested it with many other computers and removable disks but results were same.

To prevent accidental data leaks, the host computer's SD cards remain offline by default when booting from a Windows To Go (WTG) USB drive created with the built-in Windows To Go Creation Wizard or Hasleo WinToUSB. This tutorial details how to bring SD cards online in a Windows To Go workspace using Disk Management.

Step 1. Boot Windows from the USB drive created by Hasleo WinToUSB.
Step 2. Run cmd.exe as a administrator.
Step 3. Run Diskpart at the command promptDISKPART>sanDISKPART>san policy=onlineallDISKPART>list diskDISKPART>select disk 2DISKPART>attributes disk clear readonlyDISKPART>exit
Step 4. Eject the SD card from the card slot and reinsert it.
Step 5. Run Diskpart at the command promptDISKPART>list diskDISKPART>select disk 2DISKPART>online diskDISKPART>exit
Note: Replace the disk number with your SD card's actual disk number. Following these steps, you can online SD cards in Windows To Go (WTG) workspace easily.
A: SD cards remain offline by default to prevent accidental data disclosure. This security measure protects data on removable storage devices when using Windows To Go on different computers.
A: SD cards (removable media) require using diskpart with the 'san policy=onlineall' command to change the SAN policy. This allows Windows To Go to recognize and online removable disks.
A: Run 'san policy=onlineall' in diskpart to change the SAN policy to online all disks. Then use 'attributes disk clear readonly' and 'online disk' commands to bring the SD card online.
A: Yes, after changing the SAN policy and disk attributes, you need to eject and reinsert the SD card for Windows to detect it properly and allow online status.
A: This method works for most SD cards. However, some very old or non-standard SD cards may not be supported. The key is to use diskpart with proper commands in administrator mode.
