Sophos Central -> Endpoint Protection -> Policies -> Peripheral Control -> Base Policy -> Settings
If you change this to 'Control access by peripheral type and exemptions'
Then, change 'Removable storage - XX detected to 'Block'
Then, click 'Peripheral Exemptions' -> 'Add Exemptions'
Change the drop down box to 'Removable storage'
Tick the device, change Policy to 'Block' and Enforce By to 'Id'
Does this meet your requirements?
