I've looked into the error using Google and searched here on the forum but haven't found anything to explain why Smart Defrag is causing it.

 

I'm on XP Pro SP 3/1GB RAM/P4 2.8/232GB HD

 

Your help will be greatly appreciated.

Hi Glenn 1,

 

Please try the following methods to see how it works.

 

Open Control Panel>>System>>Hardware>>Device Manager>>Universal Serial Bus controllers>>USB Root Hub>>right click Properties>>Power Management>> property: "Allow the computer to turn off this device to save power". By default that was enabled, please disable it to see whether it solves the issue.

Hi Cicely,

 

Thank you for replying and giving me your advice. :smile:

 

When I read your reply I realised that the error was referring to my External Drive which is a Seagate Freeagent Portable External that connects via USB which has been assigned the number 5 which I found listed in Disk Management.

 

I did as you advised, and changed the power management setting for the USb Hub that I use for my external by unchecking "Allow the computer to turn off this device to save power".

 

I then ran Smart Defrag and checked in Event Viewer > System to see if the warning happened again.It didn't happen the first two times I ran it but has just happened again.I also just noticed it happening when I'm not using Smart Defrag.

 

XP seems to be doing something to cause it too, but not sure what.I also noticed yesterday that my restore points only went back to a month ago despite Restore being set to use the max 12%.So I checked the Volume Shadow Copy service and it wasn't running and reset it to Automatic and restarted it.

 

I wonder if XP is causing it when it takes a snapshot of my external ?.Still not sure why it happens when I use Smart Defrag either.

I continued looking into it and I set my external drive to Optimize For Performance instead of Optimize For Quick Removal under Policies in Disk Management.

 

From what I've seen online it's a consistent problem with mainly Seagate External drives.There's a big thread about the Event Viewer ID 51 error here: http://www.hardwareanalysis.com/content/topic/12946/?o=520

 

It seems to be happening when the external drive idles, apparently it's built into the external drive to go into an idle state with no activity after some minutes.

 

I've tested this theory myself by using Smart Defrag to Defrag and Fully Optimize my external drive.It took 1 hour and 10 mins and while it was being done there were no error 51's in Event Viewer.I also played some video files from the external and there were no errors while they were playing and the drive was active, but it did happen when I resumed playing the video after pausing it for a while.

 

The errors also happen when I haven't went into the external drive, so that must be XP causing it, possibly when it's taking a snapshot for backup.Although at the time the drive was active playing video files.

 

I'm thinking this Event Viewer ID 51 error on my external drive might be a false negative caused by Seagate, mostly when the drive goes into an idle state after some minutes of inactivity.

 

So it's not Smart Defrag that's to blame for these errors, it's a known problem with Seagate and a few other external drives generating false negatives in XP.
