Hi sc-w,

Since most companies are not going to sell you just parts of a hard drive. Well the only option I can see for you here is that you have to buy the same model hard drive from a local store or online store wherever it is available and then you need to cannibalize the good hard drive and put the parts on the defective hard drive. As long as you are sure that the only damage to your drive is the PCB, it should work and your data should still be intact (no guarantees though!). Though this might become expensive for you, but like you said your data is what matters most to you right?!

This is the same procedure that most data recovery company do to salvage information from broken hard drives.

Hope this helps!

Peace! :)

The Printed Circuit Board controls many functions to operate the hard disk drive, There are 5 main features of a the electronics that can be unique to each drive that is likely to fail, the first being:
POWER INPUT The most problems we see here are mostly human era... forcing the power plug in the wrong way Unfortunately apart from a few notebook PCB's the is no protection fuse to prevent PCB Damage There is also risk of power surges making it through to the electronics as well
FIRMWARE Firmware is unique to the PCB this controls calibration and track information so it is very rare to be able to interchange the same model PCB with one that has another firmware revision... so what this means, if your board shorts out the firmware unique to the drive, you will be in trouble. Of course a good main stream data recovery company will be able to replace this and manually reprogram this chip
SPINDLE IC This controls the speed and rotation of the spindle rotating the platters internal to the hard drive assembly or HDA These intend to get very hot at times and can often short out… The most famous of models to this was the good old quantum LCT, particularly the TDA5247HT Chip; this would go up in smoke and leave a pin hole or a very big mess on or over the IC






MICRO CONTROLLER These rarely fail unless there has been an extreme hit by power such as a lightning strike that may cause voltage through the IDE Cable. If this does fail you would normally find visible damage
TRACKS Internal track are the thin Copper ribbons that run through the board that connect each component these can be easily damaged bay any of the above case scenarios, but one of the most common that I have seen is Corrosion Below is a great Example of how quickly chemicals in the air from industrial workshops or even sulfa in the air from volcanic regions can cause havoc... but for most residential computer hard drives its condensation that damages a PCB
In this example this PCB was only 6 months old









WARNING IF YOU CHANGE A PRINTED CIRCUIT BOARD WITH A NON MATCHING PCB... SUCH AS DIFFERENT FIRMWARE, LAYOUT, OR MICRO CONTROLLER NUMBERS, YOU WILL RUN A HIGH RISK OF FAILURE AND FURTHER DAMAGE!
Yes there's a high chance...
YOU WILL SEE SMOKE!!!!!! If you have an exact match to the PCB you want to attempt swapping, the risk will be minimal but what allot of people don’t realize, is that code can change overtime even with exact matching parts.
What this means is... if you were to purchase two NEW exact hard drives at the same time from the same batch and then swapped there PCB's to each other, you would most likely be successful!
Try that same scenario 6 months after heavy use... and results will could be very different There's a high chance that each PCB has made themselves unique to each drive!
How can this be? Its called SMART Technology where the hard drive is designed to reconfigure itself during operation to maximizing performance and protecting data. If a sector is read slow but functional the drive will remap this sector as bad and move this sector creating changes to track and sector information in firmware Now this new reconfigured information is unique to the drive, and can cause this PCB to be incompatible with any other drive of matching numbers.
As a data recovery engineer it is always best to repair the Original electronics of a failed hard disk drive That way you get maximum results with very little risk, Most high end data recovery companies have the expertise to replace many, if not all components on the PCB.. but not only physically but replacement, but this may also involve new components and reprogramming.

antenna wire connection on the circuit is cut and I do not know where the weld

you might need to solder it
You attach wires to printed circuit boards (PCB) in a process called soldering. You heat the wire and PCB pad, melting the solder wire and allowing it to flow onto the wire and pad. The solder wire used is typically a lead-tin alloy although in some special cases, silver is used. Soldering a wire to a printed circuit board may be part of making, repairing or modifying the board or connecting it to another device.

Clean the pad on the circuit board where the wire will be attached. Gently rub the eraser on the pad until it is clean and shiny. Strip about 1/4 inch of insulation from the wire. Tin the end of the soldering iron by melting a small amount of solder onto the iron tip. Heat the wire end with the soldering iron for a few seconds and briefly touch the solder wire to the bare wire, just long enough to melt the solder, and let it flow into the stranded wires. This is called tinning the wire. Tinning the wire is not necessary with solid or single strand wire. Insert the wire end through the hole in the circuit board pad from the top or component side of the board. Bend the end of the wire slightly to prevent the wire from falling out while soldering but do not let the wire end touch any other component lead or another pad on the circuit board. Apply the soldering iron tip to the wire end and solder pad at the same for a few seconds until the solder used to tin the wire end melts. Apply just enough new solder to make a dome-shaped puddle on the pad that covers the hole and the wire. Remove the iron from the pad but do not move the board for a minute. Cool the new soldered joint and do not move the board until the solder hardens. Clip the wire end off with the wire cutters. The wire is permanently attached to the printed circuit board.

My vid card fried and i do not know what my motherboard supports so i can buy a new card


Fried? You need to know that your mobo's PCIe video interface is okay if you want to have a new card work. If you have an aged system go on and search for the part number (usually on the PCB near the videocard slot) and see what you're dealing with.... That's just not a very thorough diagnosis of your system state to say 'fried,' but PCIe has been the way of the world for 10 years now....

Need to replace my harddrive


Hi,

If your system is running under warranty. I suggest not to open the system. Just take the system to manufacture support center they will replace it without any cost.

But make sure you have the bill copy and warranty document with you.

If it is already over just unscrew the cabinet and remove the replace the new disk with new one.

I lost my msi motherboard cd, need help getting the drivers. cant update my nic card to be able to connect to the internet to use driver update software programs.


Sir,

Before getting driver from manufacturer website you should know mother board model. no and year of manufacture etc etc.... This can be detected by a small software called belarc advisor(search at google, it's free download). Download and install it. It will detect the motherboard no., after getting the number u can search at google for driver download.

Thanks
Good Luck

Need jumper diagram for motherboard


Hi,

Check that the hard drive is set to "slave" on the jumper settings where you connect it (if it's IDE). Also, check the boot order in the BIOS (or setup as it may be called when booting up) to make sure that they computer's not trying to boot off the new drive rather than the old one. I don't think the jumpers on the motherboard will help you at ALL. Drive jumpers are the only thing and as mentioned - set the new drive to SLAVE and make sure the original drive is on MASTER (this is usually all recorded on the top of the drive on the label)

Good luck!

Which specific harddrive components would you put into a home-assembled PC?


DUE you're going to work with graphics files you need a good HDD (capacity) 500 GB will be great
Memory at least 1GB and above
Processor 3.0 Ghhz and above
DVD Drive (any double layer)
Sound card (on board is enough), however you can improve later adding a new one, but you don't need that)
Good Graphics card (At least 256 MB)

The jump drive will not boot into "my Computer"


ive had problems with jump drives in the past and ive found the the ceaper they are well the cheaper they are. my burned up and fried after 3 uses. it may very well be poor manufacturing.(Have you tried using it in a diffrent computer?-try putting it on a friends computer to see if it detects it.) or a driver problem.
to find new drivers, you may ned to acess your control panel-->add hardware. and check for new hardware. it should search for drivers for your drive and appear. *their may be a few options you need to choose from*
i hope this helps.

Try to see in the bios, which is the boot sequence. It could be IDE first and SATA second.
Change the SATA to first.
Or see any option that talks about the boot sequence.
