Recovering data from WD EARS drive
datora:
.
Sorry this is a "day late," but ran across this freeware utility:
- http://www.pcinspector.de/default.htm?language=1
PC INSPECTOR™ File Recovery
It was linked from HP/Compaq as a recommended (but not officially endorsed) utility, especially for erasing drives. I've not used it yet, but likely will over upcoming weeks.
Also this:
- http://eraser.heidi.ie/
- http://www.heidi.ie/node/6
Eraser 6.0.8
While I'm not generally a fan of HP or (even less) of Compaq, the fact they would link to these from their corporate site gives me enough curiosity and confidence to give 'em a test spin at some point. So, leaving "bookmarks" here while I continue system rebuild & file recovery operations in my cave.

Though the EARS drives use 4k sectors internally, the firmware only exposes 512B sectors to the OS, so they effectively are 512B-sector drives as far as the OS is concerned. ‘True’ 4k-sector drives won’t be out in the market so soon, at least not until proper 4k-sector support is widespread in all major OSes.
The only concern is decreased write performance due to unaligned sectors, but this does not affect basic hard drive operation. Your usual data recovery tools should work just as well on EARS as on the older EADS drives.

From what i know this is False. The wrong Align of hdd that use 4k not allways slow down performance. You can look at WD forum/newegg reviews, where alot of people report that they get alot of errors in Smart etc... all because they use those HDD's at XP without knowing nothing about AdvFormat aka 4k sectors.

It should be reserved for a last-ditch, Hail Mary attempt after EVERYTHING ELSE has completely failed. ]

I tried to tell him that myself, but... >.>
Edit: He said he tried the demo version of R-Studio and got a ton of read errors there as well. I've been recommending him programs that were mentioned in this thread, which I created last year.

Errors could came from bad align - or the app dont support 4k sectors.

He's been running some odd HDD tools. The latest one he's trying gave him a slew of read errors (pretty much every sector).
He's insisting on replacing the controller board, even though I'm quite certain it's fine, despite the errors.
Edit: Knowing all that, do you reckon a dd would work?

Probably because of 512 vs 4k sectors. There was a WD recommanded app for those hdd's.
PS. You can look at topic I made some time ago about me breaking Partition Table and fixing it with Acros... something application - not sure now. Mayby thats the problem, corrupted partition table = unallocated space

It's alright, I think he's given up by now. I'll let you know if he's still struggling. =)
