Full scan not complete

Hello,
when I start full system scan or specific hard drive(s) scan with my Norton Security 22.9.4.8 (Win 10 home, all up to date) it always freezes in the middle of scanning. Scan stops on random files, very often around 500k-600k items. I can't stop or pause scanning after that, only OS restart helps. I read the discussions here and I tried to turn off scanning of comprimed files. I also reinstalled antivirus completely. It had no effect.

Any ideas?

Thanks, Martin

Re: Full scan not complete

It could be a physical problem with your hard drive. This can cause the type of issue you are seeing.

To check your hard disk, click on the Windows Start button. In the search box type CMD. Right click on cmd.exe and click on run as administrator. In the command prompt type "chkdsk c: /r"  without the quotes. A message will come up asking if you want to check the disk on the next restart. Answer 'Y'. Reboot and the check disk will run before Windows starts up. This check will check the file system as well as the physical disk surface. This scan can take a long time, depending on the size of your hard drive.

Thanks for advice, I will try it.

However I have multiple drives (including HDD and SSD, SATA and USB, local and network) and problem occurs on multiple storage devices. Maybe only common thing is that drives where this happen are connected over USB (I'm not sure if it is a clue or just a coincidence).

If you can identify an individual drive that is being scanned when you have the problem, then you can target that drive for the chkdsk.  In any case, do not run it on the SSD.

Re: Full scan not complete

Problem occurs on multiple storage devices, some are SSDs, others HDDs. It is not one specific disc or system unit. Up to now, problem was always with USB connected discs. SATA connected drives like my system SSD or additional internal HDD were ok. However as I mentioned before, I'm not able to confirm that this is related to USB connected discs/USB protocol, I have insufficient data to confirm or disprove this assumption. I would like to add that affected drives are connected over independent ports and some of them have independent power source, others not. Excluding norton scanning I have never experience problem with these drives.

Maybe if you have time, try disconnecting all external drives then try your scan. If it runs fine, try again after adding one of the external drives. Repeat this adding one more drive each time until you see the problem again. This might help identify where the problem is.

Re: Full scan not complete

Thanks for hints. Problem is in drives connected over USB or in number of files. Other drives (SATA, network) are not affected. Scan is successfully completed if affected drives are not plugged into PC. Affected drives have wast amount of small files (approx. millions). All data on these disks are also encrypted but I have never experienced problem with encryption software and I have encrypted all drives and others are ok so I don't expect this is the issue. When I will have some free time I will try investigate more details.
