hehe... since roxy bring this matter up...

yep, according to SeaTools or even HardDisk Sentinel, :



hard disk model ID (from software and sticker clearly different). However, I am a bit confuse when software report that this hard disk has 16 heads?

Isn't 16 heads for 4 platters?

7200.12 500GB use single platters with 500GB per plate density (highest from seagate so far). So it clearly different from 7200.11 which use 250GB and 340GB per plate. hmm...

To check warranty though, I can use either 3500418AS or ST3500410AS. Both model with same serial number (?) give 2 Jan 2014 warranty coverage.

What I can assume now, 7200.12 use latest generation plate (500GB per plate ... yes this 7200.12 is slim hard disk one) but perhaps use the same circuit as 7200.11 but with different firmware.

Found this piece of info... quite worth to read especially the dialogue between customer and seagate staff and also the benchmark of 7200.12 using hdtune (hdtune show model number as ST3500410AS instead of ST3500418AS)

but the funny and suspicious thing... Seagate forum moderator keep deleting any thread or post asking the difference between this 2 models.

So...not professional

I take the second one

"Forgot to rename drive model internally..... 2 days after massive shipping and one of their engineer say "Oopps....we forgot to change its name in hdd rom". Craplicous

Firmware : CC33

Perhaps not yet...but hopefully no problem.

7200.12 clearly different hdd than 7200.11 albeit its model number quite confusing (sticker show ST3500418AS but software show ST3500410AS).

My a week old hdd already has 1 bad sector ?!?

I use this one :

AFAIK, 7200.11 problem is its firmware, not plate or servo motor. Tick2 sound more related to servo motor right.

my 7200.12 so far doesnt exhibit that problem yet. Maybe I rarely cold reboot
