Until one of our distinguished moderators and other experienced forum members can review your post, could you please provide the following information so that they may better assist you?
- Your computer's operating system
- Name of any other security software you are using (besides McAfee)
- What is the average size of your files on the external HD
- When scanning your main hard drive, does McAfee take as long to scan the files on it?

- Well my OS is Vista
- I am not using anything else
- The average size I would have to say is about 300 MB
- When scanning my computer actually drive, no it doesn't take long.
As an experiment I select a folder with 22 items in it, the total size of the folder was 4.8 GB. On the external Hard Drive it took about 3 minutes to scan 3 items, when I moved/copied that folder to my computer, the scan was done in less than 10 seconds.
Hi again theflyingmonkey!
I have pasted below a link to another post in the forums here which another member made back in June. The poster had a similar problem as yours and there were quite a few responses from our forum members & moderators. Please look through the post and responses, as there are a number of helpful suggestions there. I will make a post in the forums and see if I can get a moderator to review your post here, since no one has as yet.
Please let me know if anything recommended in the other post was helpful to you!
VirusScan may not be able to unpack that file for one reason or another.
It could be corrupted or contain something that VirusScan isn't sure about infection-wise, or your hard drive could contain read errors. It can also happen if the drive is compressed.
Do a disk check on it. Go to Start and type cmd on the Search box. In the space above cmd.exe will appear. Right-click it and select 'Run as Administrator'.
In the command prompt window type in chkdsk X: /r (WITH the spaces and alter X to whatever disk letter applies to that drive) and hit Enter. It may take a while depending on the size of the drive.
I recommend you contact Technical Support Online Chat via Useful Links at the top of this page.
The data transfer speed differs between the USB 2.0 and SATA interface . For usb 2.0 the speed is 480 Mbps, where else in SATA Internal HDD will be 3.0 Gbps or 6.0 Gbps operation. Offcourse you will have the scan time increased when you scan External Drive when compared to the Internal Hard drive. When scanning large files it will take time to complete the scanning operations but it should not take too long.
