Hi! I used the intel migration tool to clone windows 7 to my 330 disk. I used msinfo32 to check the sector alignment and it gave me the value 512. Is this correct?
You can run the command:
wmic partition get BlockSize, StartingOffset, Name, Index
...and look at the last column labeled "StartingOffset". On a Windows Vista/7 installation, it will normally be 1048576 which is fine for SSDs. Integer multiples of that number are also fine. What you don't want is a number like 32256 which is the default offset for Windows XP and earlier.
You can also just download and run the AS SSD Benchmark program (http://www.alex-is.de/PHP/fusion/downloads.php Alex Intelligent Software - Downloads) which will tell you in green or red letters if a drive's particular partition offset number is OK or not.
Don't be alarmed by a large offset number. The actual system partition of an Windows 7 OS drive will often be offset further by a 100MB recovery partition resulting in a number of 105906176 (aka 103424 K) which is still good because it is dividable by 1048576
