Hard Drive backup wont spin up
Posted 11 February 2008 - 07:21 AM
all went well.
dont know why but i defragged the external drive.
now the drive will start to spin, then fail.
I cant see the drive in 'my computer' on the desktop
do you think the disk is now U S?
Is there any way of recovering this data - except paying an arm and leg
I have googled this and no joy - hence trying here

(i.e. Partition based recovery)
and only of it does not work, a file based recovery program, like the enclosed Photorec, or any of the other ones, just search the board there are several threads listing them.

Thanks for that info.
What confuses me though is the disk worked fine as a back up BEFORE i used disk defragger. so wonder if its hardware or software related issue????
i'm gonna try what you sugested to see what happens

(can you even hear it spin up?)

Can you explain me the reasoning behind this? I got a dead one I gave up and wonder what this does.

Electronics components have a working temperature range, usually comprised between -30° C and +65° C, for "normal" grade components, usually -40° C and + 85° C for "industrial grade components" with some components that allow for a -65° C to +125° C :
WITHIN the given temperature range, there is an "ideal" working temperature, that almost invariably is around the middle of the allowed range, more or less amounting to a temperature at which the users of them (humans) live and operate them, i.e. +0 °C to 40 ° ,but WITHIN designed range, components behave anyway WITHIN specs.
The "freezing" as well as the "tapping" method to revive a dead hard drive, can, in VERY RARE occasions allow for a TEMPORARY revival because they may resolve a mechanical problem, including defects in the soldering or connection of a component.
Remember also that every year hard disk technology changes dramatically, and what may have worked in a particular occasion, on a particular type of failure, on a particular drive model/capacity most definitely won't work with next generation of drives.
You can also try shouting very hard at it, using a magic wand and some spells on it, you can freeze it:
as well as "boiling" it:
But ALL of them should be a LAST, LAST resort, only after you have decided that your data was not precious enough for you to attempt a recovery by a professional, and you have nothing to lose anyway.
If it's an electronic problem a more "rational" approach like this:
may work, but not on recent drives where the board is "coupled" to the innards.
I would suggest everyone to check the above links and this one:
then judge themselves what would be more wise to do.

Don't think it's easy, you have to know the right words, usually electronics are rather "tough", what helped is some occasions was having a BORG recording of the sentence:
played VERY loud for a few hours.
(but do not put the loudspeaker TOO near to the dead HD, it's magnet won't do any good to the platters )
