Just wondering is it possible to get data from this condition, platter scratch
Thank's

nope.. no chances at all ( this is I know so far ).
Hopefully future technology in platter cleaning can solve this problem.

Ouch!

you guys heard of VOGON? they use blue laser to scan the platter?

No i heard and have information about MFM Microscope Force Magnetic or STM Scanning Microscope, but this is an idea i dont know any people who work´s on Data Recovery who have more than 1 millon of dollar´s for paid a machine, used on Factory, for Check Surface on test´s

Your head crash, its near the SA zone and user data zone , so if u try perhaps u donnor heads will be damaged again. when the Head crash its on the land zone on 3.5" for example u have a hope to be able to recalibrate and get some of data


Best Regards.

That's Bullshit

Starling....

You said just what I was thinking..

Utter crap!!

What would a laser do ? Its the head that reads the info on the platters .

Unfortunately, MFM/STM/whateverM won't help here since it will take an eternity to copy several tracks...

your right no laser can read magnetic bias that I've heard of. I'd say these platters are toast as you'd likely kill the new heads as soon as they hit the scratches. Even if you could guess well and edit tracks to ignore the scratches you'd still have to go across them with the heads.

It is possible to read magnetic data with laser (for example Seagate Recovery Services can do this)
The problem is - nobody can get data from this magnetic copy (may be in future but not now)

Hi Doomer where did you see this? I'd be interested in seeing this. The only use of laser I've read about is for checking the platters during the manufacturing process for defects.

Exactly but laser does magnetic copy of platter and that copy could be used for defects searching

Hmmm know any websites that deal with this? Now I'm really curious

Hi Doomer spent some time searching, I think they use laser to help with positioning, GMR heads are still used for the actual reading.

No you are wrong
Only laser is using for getting magnetic copy

guys go to http://www.convar.de ......they have some articles about world trade center hard drives they managed to recover, aparently blue laser was used.

Here are the articles:

Hi Guys I read some of the articles But if you read from Nortek page
http://www.nortek.on.ca/DataRecoverySer ... vices.aspx

"We often use in house designed and built servo writers with -> laser positioning <- for extreme data recovery situations where conventional techniques fall short."

I will look through the convar.de site more tonight. we only have 28.8k connection here and pages are slow to load.

Maybe Maysoft knows........

It is completely different technology
Why I am so sure ? Because I work in SRS and we have device for laser reading, it is possible to get magnetic copy of paltter only with laser but it is still impossible to get data from this copy
