Hello, I need to know if the models WD10EALS and WD10EALX (1TB. Blue) have the new ADVANCED FORMAT (4K SECTORS), like the WD Green series (EARS Models)
thanks in advanced

Formatted Capacity: 1,000,204 MB
User Sectors Per Drive: 1,953,525,169
Simple math would give 7.277 TB of unformatted capacity if there were 1,953,525,169 sectors of 4K each. I get .5K sectors when I divide it out.
man! yuo are completely wrong
The WD20EARS are a WD Green drive with the new advanced format 4k sector!
and in the page specifications says: 3,907,029,168 sectors 2,000,398 MB.
For you that drive is 512 bytres per sector too ???
No Man, the WD20EARS is a 4K SECTOR drive, only show 512bytes per sector for compatibility.
The spec sheet just hasn’t been updated… I have 1TB Caviar Green drives that aren’t AF, and I have one that is. The 512-byte sectors in the spec sheet was originally correct for Caviar Greens.
But the AF pages at the WD website only mention the green drives, so there’s no reason to think, at this point, that the Blue spec sheets are out of date yet.
As all manufacturers move to 4K sector drives, there’s no reason to believe that WD’s drives will stay 512-byte forever, but to my knowledge the Blues aren’t shipping in AF yet.
The Spec Sheet for the Blues does not mention AF http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-701277.pdf
The Spec Sheet for the Greens does say they’re AF http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-701229.pdf and then even goes on to say AF is on the RX, RS, and RSDTL models only.
Actually, between you, me and the lamppost, I think WD kinda has to leave the “User Sectors” numbers for the AF drives sepcified as what 512-byte emulation will report, because that what all disk tools will report, and if people look in the spec sheet and see they should have X sectors and their drive paramater reporting software tells them they really have Y sectors, then there’ll be no end to the complaints and misunderstandings.
By speccing out what will be reported back by current systems, I think WD is trying to avoid grief.
But, as I say, the Blue spec sheet makes no mention of AF on any models (currently), while the Green spec sheet lists just which of the current models are AF. As far as I can tell, that (along with the cache size) is the difference between the now-defunct WD10EADS and the current WD10EARS. The “DS” models aren’t AF (but there’s only one current DS model showing in the specs), while the “RS” models are AF.

No, they do not.
