Great tip! Thanks Bill. -----Original Message----- From: dba-tech-bounces at databaseadvisors.com [mailto:dba-tech-bounces at databaseadvisors.com] On Behalf Of Bill Patten Sent: Wednesday, October 23, 2013 2:45 PM To: Discussion of Hardware and Software issues Subject: Re: [dba-Tech] Image from SATA HD to SSD I have tested this a few times and it was always OK so I quit testing. To test you can use the following after loading the SSD from Whirlpool.net.au To check the alignment of your SSD's partition, it is quite simple. In windows 7, run msinfo32 by typing it into the search box on your start menu and hitting enter. click on: components => storage => disks Look for your SSD and check the partition starting offset. It needs to be divisible by 4096 (ie return a whole number when you divide by this) otherwise the alignment is not correct.

One other item of interest in their product literature was this: "The introduction of the latest HDDs and SSDs has created a new problem with volume alignment caused by changes in sector size. By changing the sector size from 512 bytes to 4 kilobytes, some traditional methods of disk partitioning have become obsolete and actually harmful. Unaligned partitions cause overall performance decline on new HDDs/SSDs. The lifespan of SSDs can be significantly reduced as a result of many redundant read/write operations caused by unaligned partitions. Using proper migration tools to copy volumes eliminates these problems. Paragon's Migrate OS to SSD component is alignment aware software that automatically places partitions according to defined 4K sectors, leaving system performance and SSD reliability unaffected." I wonder if Acronis does all of this too. Time for more research!

My current machine has a 256 SSD and it is MBR but it has been upgraded from Vista, then WIn7 and finally to Win8. I do not remember if I restored from a backup or cloned it. Acronis seems to adjust the size if you select automatic. I do remember that my daughter had a Win 8 machine for awhile and her WIndows Home Server would not back it up because it was uFHI. I checked my notes and one Windows 7 project I updated the clone process would not recognize the new SSD. My solution was to plug the SSD into my SATA USB adaptor and formatted it NTFS then used Disk Management to activate it and it worked fine.

I read up on it a bit and it apparently handles uEFI boot mode transfers intelligently so they don't get mucked up. And it can downsize the image to transfer to a smaller drive (I think most imagers can do that now - right?). But I have MBRs on both. -----Original Message----- From: dba-tech-bounces at databaseadvisors.com [mailto:dba-tech-bounces at databaseadvisors.com] On Behalf Of Bill Patten Sent: Tuesday, October 22, 2013 5:44 PM To: Discussion of Hardware and Software issues Subject: Re: [dba-Tech] Image from SATA HD to SSD Other than turning off automatic defragers non that I can think of.
