Hitcachi Fell off the table....

[LoneWolf]

This is a DeathStar 250GB that fell off a table.
The drive can not access data every time, meaning some times it can show up in the bios, and other times it won't.
Data can be accessed but it takes the drive a very slow copying speed (about 250K/s) to copy things.

What can be the reason?
what had gone wrong in it? assuming that it can access data and has not damaged it platters?

Heads are damaged. Stop working on this disk!

Head damage.

First thanks for your reply,
this disk is not going to recover, just for study.
and I would like to know what is wrong with this one.
So you are saying the heads need to be replaced in order to read the data from it?

If so, how come it can read the data from the platters?

[LoneWolf]

In addition, I would like to say that when I was trying to loose or tighten the 3 bolts of the heads arm and the other
two magnets, the drive was reading better for a short time.

I'm saying heads are damaged. you might not need to change them but its probably safer for the surfaces. You can't do anything without expensive hardware/software.

DAMAGED = not FUBAR.

The more you work with the drive in this condition, the quicker the drive will enter the "click... click....click...." state.
Head changing on Hitachi is a PITA.

because the headstack have more then 4 heads on the platters
so it can read some information.

it depends on what the drive is as there can be more then 4 heads in the hard drive

if the unit got 4 heads one is failing you can remap the headstack and use the other 3 heads
and recovery the data.

and for remapping the headstack I need some tool like pc3000 right?

PITA = ??

[guru]

The fact that it can sometimes read the SA and show up in the BIOS and the fact that it reads user area very slowly points everything towards slow death heads. However sometimes another thing can cause what you see, access the PES/() signal from the drive and then you will be able to check what maybe wrong

I can't help with any PES signal SW

Can this head problem be caused because of a "non clean head"?
Is this possible?

PITA= Pain In The Ass... Or very difficult in plain English.
Your drives head (s) a failing, it's not going to healty'er by screw/unscrew headstack
If you want the data just try to image it with some good SW.

As you did drop your drive, dirty heads it's not the problem.
If you did't drop it with the lid open on a dirty floor?

Any suggestions for a good SW?

[mr_spokk]

I put in "harddrive image program" on Google and got over 70 million hits...so there is some of them.
Acronis has good ones....the best don't come for free.

I never mentioned "free" in my last post.
asked for a good recommended one, not a free one.
Do you have something in mind?

[mr_spokk]

Sorry to be harsh, but either I don't type good enough or you need new pair of eyes!

Sorry. my bad.
First - Thanks for that, I did see that you've recommended Acronis but as far as I know,
this type of imaging won't help me that much since any bad sector will crash the software.
moreover, as far as I know, this imaging software cannot "reverse" image the drive, so I think
that this is not what I'm looking for.
Can you remap the heads on this software?

[mr_spokk]

Last spoon...open up!
Here is another good one: Media Tools Pro

Put your original drive and a drive to clone it to in a computer, boot from the cd that you have maked from their sites download section.

Well tried that too....
Doesn't seem to have any head remapping feature (or again, I didn't see well).
Imaging takes a very long time with MTP
