Does your Sony laptop have a EFI Bios?? If so it will also have a GPT partioned HD.
To clone the GPT, HD in the laptop to your SSD try HDcloning which is free and has full GPT support.
Paul, thanks for your reply.
I don't believe the laptop is using EFI. I'm not sure, but I searched and found various suggestions including the following three clues. There is no EFI folder in the C:\Windows\Boot directory. The partition type for the original disk working in the computer is MBR. It is running 32 bit WIndows 7.
Can you confirm that the HDClone software worked with an Intel 520 and the Sony YB please?
I also tried to do a fresh install of WIndows 7 32 bit from the Sony recovery disks and a fresh install of Windows 7 64 bit from a Microsoft disk and neither worked, so I don't think the only problem is Acronis. The recovery disk worked with an old 64 GB Toshiba SSD that I borrowed, so that seems to eliminate everything but the combination of Intel 520 and the YB.
I have ordered a Samsung 840 Pro in the hope that it will work.
I know it's an old topic, but I can confirm a similar incompatibility. I've bought an Intel 535 240GB SSD to speed up a Sony Vaio vpcyb3v1e. The result is extremely slow operation after cloning (clonezilla and acronis true image used - did a few tries) the original HDD. I tried a couple of times to boot but it took about 25-30 min for Win7 to display the desktop, without loading any applications, after that I lost patience. CHKDSK reported problems with the filesystem, but it made no difference fixing them. When trying to perform a clean installation (Win 7 or Win 10 - doesn't matter) there was the error Unable to format the partition on disk 0.
I've tried the disk on a lenovo IdeaPad laptop and I successfully intalled Win 7 without any glitches. I even checked the SSD with Intel Tool Box and the tests said the SSD is fine! I've been using Intel 530 240GB for 2 years on the same IdeaPad laptop fluently, and I'm very pleased with it.
From what I've read above and my own experience I'm pretty sure there is some king of conflict between Intel 520 and 535 series SSD drives and Sony vpcyb**** notebooks - at least two Vaio laptop models are listed here.
I've installed another piece of the same Intel SSD type on a Lenovo x60s laptop, a few days earlier, without any issues.
I hope this post will save someone else's troubles in trying to upgrade his/hers Sony vpcyb**** with an Intel SSD !!!
