Hey Tektron

I will check out the Ultimate Boot.  I just have to exaust everything before condeming the hard drive data.  I have to back up more often.

Thanks for the info, will try. =]

Hey Mags I've found Easeus data recovery wizard to be really good.  Not long ago a crappy partition program I was playing with suddnely trashed an internal hard drive (main boot drive) and an external drive.  Totally gone to where I couldn't even see them except from Linux.  Easeus DRW recovered everything.  At first it looked like it was just going to recover a bunch of stuff with odd names or number files but it put it all back together just the way it was.  If you use it just let it run to full completion. 

Thanks a lot for the ideas to try. Data recovery is what I am after.
I have a usb ide 2.5 drive case, but I wasnt able to read the drive with it normally. But maybe one of the recovery progs will help that situation.  I tried to put another drive in the laptop but still, it needs to get those raid drivers in when xp setup wants to have them.
So probably that is my best bet to recover first.
Again, thanks a bunch.  =]   I usually can fix this stuff, but this is my first on this problem.
Ive had dead drives before, with crazy read arm tapping n slapping, or just not fire up, as if the control board took a dump.  But I have hope now.  ;]

Was just going through some vids on yt that were associated with a vid that was in a thread.
This vid content is probably not new to most of you. But I have some interesting thoughts about some things that this vid inspired. And maybe my thoughts are not new either. ;]

In the vid he shows a laminated transformer core that is missing the inner leg, so its square.  He has a coil wrapped on one side and the core is 2 pieces, 2 C pieces.
He shows the cores have no mag attraction and applies 12v to the coil a couple times then disconnects, and the core pieces wont pull apart. Permeability. But this is not what I want to show, its just a prelude. ;]

Next he has a metal tape wrapped core, and shows that it doesnt magnetize the core permanently. Not yet. ;]   Then he puts another coil elsewhere on the core and shorts it.
Applies 12v to the original coil on the non sticky core then disconnects, and the non sticky core remained magnetized.  Only when the shorted coil was disconnected did it separate.  Ok now the thoughts.

After the 12v pulses and the core sticks due to the presence of the shorted coil, is there current flowing through that coil? If not, what state is the coil in, in respect to when it is not shorted? There must be a difference.  Is it just in a state that it would be if a mag was in the core of the coil? But with the magnet present, is the coil in the same state shorted or open?


I had asked myself some questions the other day, as to why is there the same voltage across each winding of a primary as there is on the secondary of a transformer. The only conclusion was speed of currents. Some how the transfer from primary to secondary is related to the speed of, well, whatever, electrons, etheric, who really knows.  The reason I came up with speed of the currents was that was the only thing that made sense as to each turn being of the same potential. But then I thought, it cant be speed of the currents, because we could have a larger diameter primary as compared to the secondary, which each turn of the primary would be of greater length than each secondary.  So what is the link?  Its like each electron on the primary has a link to another electron in the secondary, and they go ring around the rosie hand in hand. Is it just the change of state as I spoke of above?  Is there a spinning force axially outward from the wires that make a connection?  And in the vid, is the coil stuck in a constant spin till disconnected?

Now, if we made an air core toroid of many turns of fine wire and shorted it, would it work like a laminated core, retaining a permeable state? 

Lets say we take our toroid coil and wound another coil of larger wire and less turns on that core and we pulsed the outer coil while the core was shorted, will we still only get the amount of input power from the pulse, from the core when we disconnect and capture via diodes and cap?
Sounds a bit crazy now that I read it over, Magsnuts.  lol

I wonder how we can alter or fool how the primary and secondary relate to each other. ;]

also I forgot to mention to use GetDataBack for recovery of corrupt filesystem, it is also on hiren's boot cd in minixp
