Past night during a recording session i face for the first time the following problems.
First i saw a longer time to save the project files: 6 mb, normally Cubase takes 2 seconds, but yesterday tooks 2-3 minutes every time i saved.
Then during recording Cubase hangs, remaining frozen for 1-2 minutes then Cubase come back to normality but with a broken record part.
I felt a disk problem so i made a check disk but all tests, including SMART data, were 100% reliable on all disks
Then i made a full backup and reboot the computer. After that Cubase was ok, fast saving and no problems on recording, but was too late so i tested only for 10 minutes.
My computer is a pc build 2 years ago, I-7 24 gb ram, win 7 and cubase 9, RME Multiface.
I repeat, i never had similar issue before and your suggestions are welcome
