Windows 7: Fresh Installation of Windows 7 using ISO and OEM Key on Toshiba L450

From the tutorial, this is what you want to verify alignment:


If you want to verify the alignment (e.g. for a SSD where you are not certain whether the proper alignment was done), you use the following commands.

List disk
Select disk n (where n is the number that was given for your SSD in List disk)
List partition

Now you should see a result like this.

Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Primary 59 GB 1024 KB - but 64KB or any number divisible by 4 is also good

The offset (in KBs) has to be divisible by 4.

Note: Some readers and users of this tutorial got confused because the alignment numbers in a typical Windows7 installation are shown as:

1024KB for the 100MB partition
101MB for the next partition - which is most likely the C partition

They think that 101MB is not divisible by 4 and that there must be a problem. But that is not so. If you convert 101MBs into KBs (multiply by 1024), then the number is divisible by 4 and the partition is aligned.

Ah ok, thanks! Really appreciate the help. Now have got to this screen - just trying to do the divisions but interested in how it looks to you

Doesn't look good to me.

401 is not evenly divisible by 4 where I come from.

Wait for confirmation from others.

You can adjust alignment. I think Partition Wizard is the right tool.

I don't know how much time you have invested in this install, but you could always start over rather than try to adjust existing alignment.

Uh oh -- though 401MB in KB is 401000?

I'm not sure ...
I wonder if a new partition needs to be created in the unallocated space to see how that aligns ?????
That might show the alignment from the start of the SSD, and that should be KBs divisble by 4 ...
If it isn't, are all partitions after that mis-aligned ?????

I think I wrote out twice and possibly three times how there would be a link created under the C partition when you dragged it to the SSD using the Macrium Boot Disk, how by clicking that link you could adjust the sides of the C partition at least all the way to the left, and then set the right border wherever you wanted it depending on if you wanted a second partition.

Short of doing it over correctly you could use Partition Wizard to Resize Partition - Video Help. Drag the left border to the left, OK, Apply.

Then as also repeatedly linked check SSD Alignment - Windows 7 Forums

Ok, sorry, my mistake, i forgot that step, thanks so much for the quick fix - it looks like this now -- all advice much appreciated and hopefully that's it - also have followed tutorial advice on SSD tweaks and getting rid of bloatware - many thanks for all suggestions

Good work. How is performance? Any snags?

Thanks for your help with this - glad its looking alright now.
On booting it takes 25 seconds to arrive at the password input screen, then 10 seconds to get to desktop, but a few seconds more of thinking and the desktop icons blinking once or twice to settle down. On launching Chrome, the taskbar icons disappeared apart from Chrome, which was a bit slow. Word and Powerpoint are almost instant - much faster than before. I hope there was no harm done from the first misaligned image - my mistake, but hopefully now fixed.
Perhaps it takes a few boots for everything to settle down.
The WEI score for the primary hard disk is now 7.8, though the overall score is brought down by the graphics and gaming graphics card (3.6, 3.3) - I hardly use games so can live with that I guess, but it'd be nice to see a higher score.
The next thing I'd like to try is to re-install the HD in the DVD bay in a caddy, - hope this'll work on a Toshiba- any thoughts on this very welcome. Then re-route the cloud services through the old HD. Just reading your tips on using Onedrive and hope to complete this task when next with computer in two days.
Thanks very much again for the step by step advice.

I have not relocated a HD in DVD bay though considered that on my laptop, but decided against the extra weight. Amazon has some quality choices for this which you can research to find the one that's best for you.

What is the installed Display device and driver in Device Manager? Are there any other drivers missing?

Did you import the PC's chipset? Compare it to the drivers for various chipset devices in Device Manager like SM Bus Controller and SATA controller.

I explain why I don't use Chrome or any installed Google in Clean Reinstall Windows 7.
I prefer Firefox with Google isolated in its Search box where it isn't allowed to spy.
