Hello Joao Dimas,
Happy to here your issue is solved. Moving further your SM1 database is allocated with 98304 MB. So maximum you can alter up to 96 GB approx using alter database command.
Again to resize the disk further you can use
use master
go
disk resize name='device name',size='size in mb'
go
ex: disk resize name='SM1_data_001',size=xxxxm'
Please mark the thread if it was helpful
Best Regards,
Amarnath
