Offset/Alignment @ 4K Cluster

I am wondering if this is going to be an issue with this drive, asI have never seen this before...

I just recently reinstalled Windows 7 Professional x64 with Service Pack 1, and after running

the AS SSD Benchmark, I noticed this (in red) in the information:

Is there any way to fix this?

31 K - BAD

When I move the mouse cursor to it, it pops up the following message:

Offset/Alignment @ 4K Cluster

That 100MB partition that installer creates is used for alignment.

No its not you can install windows 7 without that 100MB partition and still have it Aligned.

This is how you do it when installing windows 7 with Method 3

Actually, that is exactly the method I followed....

I still ended up with a offset alignment...

I have fixed the problem with Paragon's Alignment tool,

so the situation has been resolved...

Thanks for everyone's help

To be clear, W7 can be installed without that 100MB partition if you use diskpart to create the alignment yourself manually. However, if you forgo both these steps, your drive is not aligned.

i thought you said you used gparted to create the partition you installed to? the method peteruk referenced doesn't use gparted at all.

creating an image of the unaligned installation and then restoring it to the aligned partition didn't work probably because the software did not respect the new partition and restored the old misaligned partition.

I said Method 3 not Method 1 or 2 from that link Method 3 works 100% and will align the partition correctly without question.
