Are you talking about the printed circuit board mounted on a hard drive?

May want to search the WEB for something like this. I don't recall anyone doing this type of repair but someone may have done this.

Nobody does this except the manufacturer under warranty. The boards are not available for purchase on the market.

purrkur, hyperspace,
Frankly Im shocked and appalled ya'all gave such responses.

hany321,
In the old days(im talking late 80s, early 90s) sometimes a drive would boot a cold system but fail when it warmed up. Usually it was a failure in the circuit board on the drive. It was often easy to get a hold of a 2nd drive of the same model that would NOT boot a system(meaning a mechanical failure internally) and try swapping boards. Im talking about the days of MFM and RLL encoded 20-40meg drives. I have never tried to "fix" an IDE drive. Its usually easier to just get another drive.

I am against buying a new circuit board to repair a drive out of warrantee. If it has data that is actually necessary to be recovered send the drive to someone that specializes in that process.

btw, If you have 2 of the same drive and want to play around, feel free to try it.
Good luck,
David

David, in those days you could take a look at the circuit board controlling the harddrive and work on it. It was dual layer and it contained regular circuitry from established players on the market that did things like stepper and brushless DC motor drivers, they used regular logic circuits and other regular components so if you had manuals on those IC manufacturers, you could pick up the datasheets for those componets and actually understand what they did and do measurements to see if they were working like they should.

Back in those days, harddrives/floppy drives were so expensive that it was worth the effort to try fix them if they broke. Hell, I have even used IC´s from old floppy drives for my own projects such as the unipolar stepper motor drivers that were common on those drives back in those days.

Today, harddrives are extremely cheap, they are built on multilayer cirquit boards and the main technology used is ASIC with no documentation whatsoever to be found. The circuit boards are not found as replacement parts on the market. In short, late 80s, early 90´s was 15-20 years ago :) The example you give (having two identical drives, one that is broken mechanically and another that is broken electrically) is the only example where I can think that changing the circuit board might work. But what are the chances of that happening??

Opps, me thinks me was more harsh then intended to my friends and advisors.

Its easier to rummage up a working drive of any model then locate a non-working one of the exact model to try a repair.
Besides, many of the our viewers were still in diapers or watching power rangers instead of wishing they could afford a 486sx back then.

Probably none. In fact I don't know anyone who has had the luck to get their hands on two identical failed drives, one mechanical and one eletroniclly. Hence my coment about "if data needs to be recovered, send the drive to someone that specializes in that work."

Off topic...
I noticed several old topics in my UNREAD MESSAGES. Is it just me or is it system changes?

There are *almost* no bad BP6s. There are mostly bad caps.

Hehehe! Well, you didn't hurt my feelings but I thought that it was better to explain my first comment :D

just try to test that

Post by hany321 » Thu Jan 27, 2005 5:43 pm

hi all
just try to test it on an old hard drive
it is vital if the hard drive contains important data on it
The Solution Is :
you need to replace the hard drive board with another one that belong to old hard drive with the same storage capacity and manfcturing date
why do not anyone try to know something crazy with old pc's and test it
thanks :)

Don't sweat it! I'll be 47 on the 3rd. Skin is getting thicker. :bigroll:

sorry but everything depends
if u know how to find the problem in a hdd it will be easy then to find the printed curcuit (as we call it - electronic) or the other thing (just calling it metal) and then replace it. but only from just the same hdd and the same model etc...
Live to get better comp for no money

Sheesh you guys, come on, we are all here to help each other. I speak as an "older" person (60+), I love this forum and will do anything to help people reach their goals (BP6) or other wise.

Just a comment from an "old fart" , maybe I'm taking things the wrong way but I think some times "egos" get in the way of the "real world", lets continue to do what we do best (support each other).

I personally get TONS of help and feedback from this group!

You people keep things going for me.

I am very lucky in that I am semi-retired and can devote time to my BP6 projects, I know most of you can't do this.

I will continue to push the limits of this board and post results (most are already known but who knows what might pop up!)

Although I have a 3.2 gig "D" system, 2 gig ram, 200 gig hard drive, 7.1 surround system and a 256 meg vid card plus 2 dual 'burners (including a dual layer burner) I still love to play with my BP6!

Why? because it is there!

Regards,

jaybird

well it's nice to have someone older and wiser here... :D :D :D
although we are generally youger...we all hope that our youth and enthusiasm gives you sthg to push everyday with...it's nice to have this page to get away from everyday stress... :lol: :lol: :lol:

also if it werent for this page i could never figure out the problems i had with BP6 board...but thanks to you, those were sweet problems...and my comp is working just fine & crunching data!!! ;)

even though i have a newer board for building new system...this BP6 gives me great pleasure to tweek is a little bit more...maybe the 366s are up next...i have maybe 10 of them in the box, just waiting to be used!!! :D :D :D
