Windows 7: What is blue sine wave on disk activity

What new drive? I thought you had the drive in hand? If it's a 4Kn drive, it can't be formatted to 512e. It must have the "AF" logo. These drives can be formatted at 4K or 512e.

Also, your specs say HP 5150. There's a big difference and causes a lot of wasted time when folks use it for reference.

Forgot to mention:
Check with the drive OEM. The utility may not work with USB connected drives. Many have to be connected directly to the host controller (SATA port) for such utilities.

carwiz, here's an update:

5/17/15 Results of Windows Backup of C drive files and image 5/16-5/17/15

Took 19 hours.

5/16/15 11:02am - 5:50am ~19hrs - 358.35gb free of 2.73tb(??) bu size = 717.36gb
scale shows space (2.73tb) 3/4 consumed - not!
vol properties shows 721gb used/2.02tb free; resource monitor shows 2,861,427mb total, 2,123,039mb used.


Backup took 19 hours. Volume properties shows 721gb used and 2.02tb free. Backup shows 717.36gb used and 358.35gb free of 2.73tb. MS backup needs math lessons! Apparently converting the drive to work in 512e mode allowed the backup to complete but what a performance hit. MS really needs to address this. MS claims they fully support AF drives in Win 8/10, so the code exists - how about it, Bill?

Also, Realdownloader.exe (a service?) crashed about 4 times during the backup. It crashed many more times during the prior failed backups.

I would turn off indexing for that drive as well as any other external or backup drive. While it does run in the background, it can take forever on large drives and bloats the indexing tables. This will slow other drives down. You may have to delete and rebuild the index if it's large.

I can't help you with Realdownloader. It's considered an aid for theft and against Forum policy.

I don't understand indexing - how does it affect backup performance?

As far as Realdownloader.exe is concerned, it was not in use; RP just loads it at boot I guess. Just mentiuoning a 'side effect' of the backup.

If MS isn't going to address this soon, I'll probably need to buy a smaller, non-AF drive for my backups. I found the HP support forums so I'll be looking to see if I have a chipset issue.

Thanks!
