These are details from the WD10TPVT, a 2.5” 1TB (12.5mm) SATA drive from Western Digital.
It’s the Advanced Format (4096-byte physical sectors) version of their WD10TEVT disk, though with it’s current firmware you might not know it except for the small warning label on the top sticker of the drive itself.
This label suggests every OS other than Windows XP will work with this drive without any special adjustments, but I’d like to know if this is really true, or if there is a tangible performance impact of using this drive with a default partition layout on other operating systems, notably Linux.
Tejun Heo (of LKML fame) posted a very informative wiki article about the 4kb sector issue here : https://ata.wiki.kernel.org/index.php/ATA_4_KiB_sector_issues
SMART details :

Linux detection :

Oddly, WD seem to have purposefully made the drive advertise itself as having only 512-byte sectors, surely this is going to cause confusion with software trying to correctly identify and partition these 4096-byte sectored Advanced Format disks?
