Drobo

WD10EADS Advanced Format???

Just a heads up for those that might care. I put a WD10EADS that I’ve have for at least a year into a Linux server to play with a Raid 5 setup. When I formatted it I got Advanced Format performance warnings and telling me to repartition. I thought the formatter was nuts until I did an hdparm and really looked at it.

Drobos with current FW don’t care but in my case I at least like to know which drives might not play well with my XP machine, even if I buy them for the Drobo. My old Drobo drives live on in another life but this one will have to live on with my Win7 server, I guess :frowning:

I wonder if they’ve done that with the higher cap EADS drives since some people pay extra now to avoid the 4K sector issues.

Update: I realized last night that this is a fairly recent drive that I got from WD in Aug 2010 when I RMA’d a much older EADS drive under warranty. So they returned an Advance Format drive when I RMA’d a regular drive. The label does have the standard Advanced Format blurb but I never bothered to read it. I just popped it in a dock and ran with it.

interesting…
all this time ive specifically been looking for WDxxEADS drives (to specifically get non-ADF bare drives)

if you now have an EADS (not ears) which is natively ADF, then that screws my search criteria :slight_smile:

That’s exactly why I thought this post might be of interest to someone :-(.

I know that “specifications are subject to change” but I think that was quite a stretch. I don’t recall ever seeing EADS drives listed on WD’s site as “Advanced Format”.

At the current time Newegg has no EADS drives for sale except some recertified WD10EADS. No WD15 or WD20 at all. My drive was acquired as a result of an RMA, not a sale. It would not surprise me if it isn’t a WD10EARS with a “custom label” although the reasoning escapes me. The label on the drive clearly indicates Advanced Format (although I did not notice it until just recently).

My Advanced Format full model# is WD10EADS-11M2B1 with firmware 80.00A80

My other 6 WD10EADS drives are all WD10EADS-00L5B1, and I think they all have firmware 01.01A01 although I am still tracking that down. I thought it might make a nice set of matched drives for Raid someday :-). And I’m too cheap to buy that many drives all at once :-). Those 6 were manufactured between 10/31/08 and 04/14/09.

ahh yes it is of intererest indeed - thanks for the information.
i’ve still got those 7xWD15EADS that I bought and will need to reinspect them more closely.

ive bought them since xmas or early new year i think, so am stuck with them but i got a good deal and will need to start a new thread soon about the “upgrade plan” :slight_smile:

(edit) thanks Rmeyer)

Just a heads up.
