How do you check if your hard drive (or SSD) are correctly aligned?

Here and there I have read rather technical articles about the importance of having correct "alignment" on your disks. Not having this would result in decreased performance, as I take it, and this seems to be especially serious when it comes to SSD drives(?).

Is there any way to check if your drive is properly aligned? (without having to be a computer wizard to decipher the information given by the tool).

If NOT correctly aligned, is there any tool that can fix this, or do I have to re-install my whole computer? (I have recently change a traditional HDD to an SSD)...

My computer is running Windows 7 Home Premium - 64 bit

You can check via diskpart the start of the partitions on the HDD. Partition is aligned when it starts with 1024 or 2048 offset.
If partition is not aligned then Paragon Alignment Tool will align it in a simple way: http://www.paragon-software.com/business/partition-alignment/
Here are instructions on using diskpart: http://support.microsoft.com/?scid=kb%3Ben-us%3B300415&x=8&y=13

Windows 7 will be aligned by default.

An outlandish claim from Paragon that alignment can get 3 times the performance, even with their graphical example only one of the 6 clusters requires 3 I/Os on the SAN, the other 5 don't. A more accurate claim would be 20% performance incerase.
