1085 XQD Adapter Device Drivers Installer for Windows 2018-07-13
Operating System Requirements: Windows 10, Windows 11
Description: XQD driver for Windows 10 supports Sonnet SF3 Series CFexpress/XQD Reader; and also the Sony adapter when used with Sonnet SF3 Series SxS PRO X Card Reader, SF3 Series SxS Pro Card Reader, SxS PRO X Thunderbolt 3 Single Slot Reader, Echo ExpressCard Thunderbolt Adapter, Qio, and Qio E3.

For Windows 21H1 (and newer) there is an extra step required for the Sony XQD driver. Go to Control Panel->Device Manager and find the XQD device. It should be listed as a "Memory Storage Device". It has no driver yet, so it is in a special category in the list. (If you are having trouble finding it, just remove the XQD card, and you will see it disappear. Then re-insert the XQD card, select it, and click "update driver". Select "Browse my computer for drivers" and then navigate to "Memory Technology Devices". The XQD driver should be there. Select the XQD driver and it should automatically load and connect to the XQD card. After that, XQD cards should mount.

1135 Can I format an SxS card in UDF format in macOS?Jan-20-21
Yes, but you must use Terminal.
1) Open Terminal

2) Run
diskutil list
to get the name of the disk. It will be something like "disk4". Ejectable media are typically the last in the list.

3) Run
newfs_udf -v "My Volume Name" disk4
if disk4 was the correct one. The volume name is anything you want of course.

4) Unplug and replug the SxS card
(Due to somebody's bug, the disk will only mount after being ejected.)

5) You can run
newfs_udf
without any parameters to see other parameters that can be set.

The process can be automated somewhat by writing a bash script, which can be looked up on the internet.
