There's this problem apparently (which you may or may not have heard of): https://forum.acronis.com/forum/acronis-true-image-2016-forum/customer-advice-using-usb-sticks-more-32gb-will-not-be-bootable
>Be cautious to use any sticks larger than 32 GB capacity when you want to make sure that you can use them as a boot device, or to be recognized in your BIOS / UEFI firmware.
>Regularly I am unable to boot from a 64GB sized stick or being able to use it to flash a BIOS / UEFI Firmware on the mainboard because they cannot handle it correctly.
>This is especially the case when you are using such a large stick in UEFI mode, which needs to be formatted with FAT32.
>I have tried this on several computers of several age and all of them were not able to boot from this stick, nor being recognized correctly for flashing with BIOS / UEFI internal tools like Asus EZ Flash etc.
>I have contacted Asus and they confirmed that even the lastest UEFI firmware they have, do not support 64GB or larger sticks yet.
>So just in case you like to buy an USB stick, make sure that you consider the limitations.
Hence my question whether this is known to apply to SC cards as well or not.
