Windows 7: Slow SSD Boot with long OtherKernelInitDuration delay

01 Nov 2011   #101

Windows 7 Home Professional 64 bit

Last night I decided to defrag my HDD with Smart Defrag 2 and it apparently did something to fix my boot times.

Windows 7 Professional 64-bit

I realize this is an old thread, but I had a similar problem to Raillex's. I noticed a boot delay with an SSD boot drive and a Seagate HDD for data. I was seeing boot times around 17 seconds at first. Because I was setting up a new system, I didn't pay attention when the boot times increased to about 40 seconds because there were many reboots required for updating drivers and such. But the boot time remained over 40 seconds after the setup, so something was wrong. After searching off and on for months, I finally found this forum. I looked back at my Event Viewer's performance logs from August 2011 (when I assembled the computer) and saw the SessionInitOtherDuration during boot took about 25 seconds.

I had also performed an image of the SSD using Windows Backup after everything was configured and stored this on the Seagate HDD data drive. The time stamp on that backup folder is Aug 26, 10:20pm. The boot at 10:09pm (before creating the image) shows SessionInitOtherDuration at less than 1 second. Starting with the next reboot at 11:45pm, I had a 25 second delay with SessionInitOtherDuration. In my opinion, this is a pretty good implication that Windows Backup is doing something to cause this problem.

I was going to try the Clean with Diskpart Command solution mentioned earlier in the thread but decided first to try removing the "System Volume Information" folder and the folder where my image backup was stored from the HDD. I had to move the HDD to a different machine. Then I had to play with permissions and run a command prompt as an administrator to delete the folders. But, after reinstalling the HDD in my main system, the boot delay is gone! SessionInitOtherDuration is back to around 1 second without having to copy all the data off the drive first.

Either both of us committed the exact same "user error," or maybe, just maybe, there's something to our theory regarding Microsoft Backup. What I do know is that I've used the free Acronis True Image program several times since my last post and never experienced a boot delay issue.

Add it to the list of other problems with Win7 Backup Imaging. It definitely needs improvement.

Acronis is a good alternative with a free version available if your have any WD or Seagate HD's in the mix. Otherwise Macrium Reflect seems to be the top choice around here.
