Slow SSD Boot with long OtherKernelInitDuration delay

nyto said:

I think I have a problem related to this. I'm running a boot drive SSD and a 1TB WD caviar black. Is the the only way to fix it is to move the data off the HDD and wipe it? I didn't have a problem until the other day when I decided to defrag the HDD. Once I defragged it I get about a 30 sec delay at the starting windows screen before log in. My system works fine if I take the HDD out my system.

Please post a screenshot of your maximized Disk mgmt drive map with listings, using Snipping Tool in Start Menu.

What defragger were you using on the HD which caused a 30 second delay in the SSD when the HD is plugged in, but not when unplugged?

Okay I checked the Event Viewer with the bootup before the defrag of the HDD and here is what I got.

The bootup after defrag is:

There are some major delays from what was shown in the previous boot.

And I defragged with the windows defragger. The thing is there was a backup of my SSD on the HDD from when it automatically scheduled one when I first put together the system, but I never had this problem until I defragged a few days ago. I built this system nearly two year ago. If I take out the HDD everything is fine. I really don't want to back up 700GB worth of data and wipe the drive especially in the middle of school semester.

I think you've found the problem. You can verify it by running the Boot trace if you want to be sure. Cluberti might see something else as well.

If you don't want to deal with it now, you can choose Hibernate instead of SHutdown to get much faster start times. Just be sure to Shut it down fully occasionally - especially if Updates are cued with a ! on the Shutdown button.

You can also place a Hibernate shortcut on the desktop for convenience: How to Create a Hibernate Shortcut in Windows

Sound familiar? Another user (this time a company in the storage solution business) pointing a finger at the Windows 7 backup/restore utility. Microsoft needs to get its act straight.

Not sure it's related to Backup imaging, more likely boot sector or some other corruption of the HD.

Windows Backup Imaging has its shortcomings but we need to see more evidence it is involved here.

True. My case doesn't seem to fit the mold. I had a backup stored on my drive from Microsoft backup and didn't have the problem until I defragged. I guess it rearranged some boot info to a spot that my system checks to cause the problem.

I can concur with that. I use Windows Backup to a dedicated internal drive. I've used it twice to restore since January of this year and haven't noticed any problems. It's been a backup drive since day-one and it appears Windows knows this--It's locked out of certain functions.

Fair enough, and perhaps I'm jumping to conclusions. In my defense, I went from a 17 second boot to a 38 second boot with no other change than imaging my SSD boot drive with the built-in imaging utility. I fixed the problem a second time using the clean command in Diskpart, and it hasn't resurfaced.

Did you check the box in the Microsoft imaging utility enabling imaging of the boot drive's MBR? I think the default option is unchecked, but I'm not sure.

I have the "System Reserved" box checked. But I'm not sure this is the MBR.

That's the one. Guess I can discount that particular theory.
