head swap question....

[SlipStream]

hey m8's

i built a clean box with hepa filtering, basic but it works. i did a head swap on a WD5000AAKS, everything went great except when i went to power it up, the platters spin up, heads run over the platters 3 times, and they spin down, did i do something wrong???? model, manufacturing date was within a month of each other, pretty much identical as far as i could see. please help.

first post? seek data recovery expert close to you if you need your data.

[SlipStream]

ok, plz dont tell me to seek someone that costs alot of money, this is a project, not for data recovery. oh and just because i only had one post, that means no one can help me????

WD5000AAKS... you couldn't have picked a much more difficult drive.
and how did you determine it needed head swap to begin with?

[SlipStream]

it was a project i have been wanting to do, i had a pair of matching drives, and i asked my teacher how hard it would to do this and he said not that hard, i am on the final step, and just having spin up problems.

[Real_Jose_Pinto]

ask BlackST, he's an expert.

[Steve]

I suggest you read all the posts in this forum about changing heads
on WD drives , and tell your teacher he has no idea what he is
talking about as far as how hard it is .
There is much more involved than just moving the heads from one
drive to another.
Was the drive working before the head swap?

[SlipStream]

well i might have over emphasized what he said, he used to work for data recovery business, whatever... um, yes both drives were working prior to dissasembly.

[Steve]

So put the heads back in the original drives and see what happens.

[SlipStream]

did, same thing happened.

[BlackST]

Now take your 'teacher' to your 'clean room' and ask him to put everything back in working order...simple. P.s. Even in the DR business these Wd drives are known as PITA...

[SlipStream]

ok... but is this a symptom of a particular problem????

[HDD Spaz]

Even true experts struggle with this drive. It's not your fault you have been misled. I suggust do your own research and get another teacher as your teacher is an ignorant cock.

[SlipStream]

lolz, kinda cant, is a required class. y is this drive so hard??

[BlackST]

A class in dr? Is by a chance at Seagate College or at Western Digital Institute? Come on, be serious.

[SlipStream]

no DR, has nothing to do with this class, it is one of my classes "modern storage devices", i am going to school for Electronic Engineering. it was a topic that came up in a discussion, and i wanted to see if i could do it. guess not . but still, y is this one of the hardest drives to do??? it just happened that i have a ton of these laying around, would it be eaiser if i use an older set of 36gb raptors???

[BlackST]

To ensure success try on mono platter mono/2 head. No issues. A common seagate or maxtor. When I started body building I did not bench press 100 kg.

[SlipStream]

lolz, good analogy.... is a raptor "old 36gb" fit into this type, i have been swaping them out for the new 300gb raptors, and i have about 6 of them laying around.

[wiseleo]

"Performance" series of anything is not a good idea. They tend to be more complicated and have tons of platters.

A couple of 7200.7 Seagates of 40GB capacity should be the easiest to prove the concept.

Don't do multiplatter disks.

wd360gd "which is what i have" are single platter, mono head, hdd, i might give those a go...
