I currently have two WD10EACS 1tb Drives. These drives have 32mb cache and use legacy 512-byte sectors. I am looking at replacing the 2nd Drive in my system with 1.5tb WD15EARS. This drive has a 64MB cache and ues use a new platter format, which is known as ‘Advanced Format’. Instead of using legacy 512-byte sectors, these new drives are prepared in 4KB blocks (of eight sectors). Will these drives work OK together.
The new drive will be used for backup disk images & storage. I would hate to make a back up only to discover that it wasnt compatible in case of a restore
