A week ago I plugged a 3TB HGST HDD into my PC using a USB attached Rosewill external enclosure. That was probably a mistake.
Only 746GB appeared, I formatted it anyway, GPT. After a bit of research I decided 3TB was beyond the capabilities of the Rosewill enclosure. It successfully Ejected using the Safely Eject system tray icon.
I placed it in the PC hooked up to a SATA port. Voila, all ~3TB are there. I deleted the 746GB partition & full formatted the entire drive. Copied terabyte plus onto it, everything looks good.
However, every time the PC wakes from Hibernate I get this pop-up.
Backup2 - 3 TB
Would you like to scan this USB drive for threats? Your scan time will change depending on the size of the drive.
You can change your scan preferences in your settings.
This is not a USB drive. It was for a few minutes before I stuck it the case. Does Norton think it is still a USB drive? I must have confused it.
Clicking yes does not stop it from prompting to scan again. Prompts only coming out of hibernate, not startup, not sleep mode. As if each time the PC comes out of Hibernate it thinks I have connected a new USB drive & prompts me to scan it.
I have another 3TB Barracuda, connected to the same controller (not RAID). Norton does not prompt to scan for that one. Of course, it has been in the machine since before Norton.
I could go to Norton 360 > My Account > Settings > Scans & Risks > USB Drive Scan & select Off, but that does not seem like the appropriate resolution.
Norton 360 version 18.104.22.168
Windows 10 Pro 22H2 version 19045.2728
