7.5.3 Checking SSD partition alignment

If you installed Windows Vista/Windows 7 from the installation DVD to a new hard disk, the

operating system automatically aligns the hard disk during installation to a multiple of 4096 and

usually to 1.024 MB. In any case, it will be useful to check.

Mount the SSD into the intended location in your computer.

Windows Vista/Windows 7

1. Type cmd in the Search field and press Enter.

2. At the command line prompt type:

wmic partition get BlockSize, Index, Name, StartingOffset

You will get the output looking like this:

In the screen shot, disk 0 has an incorrect alignment and disks 3 and 4 have the correct alignment.

Windows XP

In this case the procedure requires more commands:

1. Type cmd in the Run field and press Enter.

2. At the command line prompt type:

diskpart

list disk The screen will show the disks connected to your computer. Find out the disk

number for your SSD using its size as reference

select disk N Here N is the number of your SSD

list partition

The output will show the size of SSD partition(s) and offset value.

If the SSD has an incorrect offset value, see Fixing SSD partition alignment (p. 149).

7.5.4 Fixing SSD partition alignment

If you did not properly prepare your SSD before transferring your system to it, the starting offset may

turn out be incorrect. For example, this may occur if you upgraded Windows XP to Windows Vista/7.

Let's see how to fix the alignment problem.

1. Start True Image 2013 and click the Backup and Recovery tab.

2. Create a task for backing up your SSD in the disk backup mode.

3. Back up your SSD using as destination, for example, an external hard disk.

4. Shut down the computer and then boot using Windows installation CD.

If you have a WinPE-based Acronis rescue media, you can boot from it. Boot to True Image and then exit it

to go to the command line prompt.

At the command line prompt type:

1 2 ... 144 145 146 147 148 149 150 151 152 153 154 ... 240 241
