I used provided by Intel Data Migration SW (Acronis) to clone my current Windows 7 boot drive to SSD.
Everything seemed to go well. I can boot and work from this new SSD.
But when I go and check partition alignment I see very strange numbers (as if Data Migration software did not know that target drive is SSD).
Partition alignment is 31KB !!!
here is the info reported by msinfo32 -> Components -> Storage -> Disks:
Description Disk drive Manufacturer (Standard disk drives) Model INTEL SSDSA2CW120G3 ATA Device Bytes/Sector 512 Media Loaded Yes Media Type Fixed hard disk Partitions 1 SCSI Bus 1 SCSI Logical Unit 0 SCSI Port 1 SCSI Target ID 1 Sectors/Track 63 Size 111.79 GB (120,031,511,040 bytes) Total Cylinders 14,593 Total Sectors 234,436,545 Total Tracks 3,721,215 Tracks/Cylinder 255 Partition Disk #3, Partition #0 Partition Size 111.79 GB (120,031,478,784 bytes) Partition Starting Offset 32,256 bytes
Why Data Migration software used an Offset incompatible with SSDs?
