what is better: to match pcb model or drive model?
Replacing a defective hard drive excursion lath is non an piece of cake bandy. The new PCB must exist adjusted for your hard drive. Without the necessary steps to adjust to the new excursion board, your hard drive volition not function properly and information volition non exist accessible.
At that place are few things to know before y'all go along:
i. Not every hard bulldoze failure is due to a bad PCB—only about 25-30% of data loss occurs due to failed electronic components. Even what seems to be an obvious sign of a PCB failure could be a completely different (often mechanical) outcome. If fourth dimension and data are important, consider sending the states your hard drive for our diagnostics and PCB accommodation services.
2. When a circuit board fails, you may need to take a few additional steps to make sure your difficult drive is working with the new PCB. Read this unabridged HDD Circuit Board Replacement Guide beneath to understand the process, and improve your chances of successful information retrieval.
Step 1. Understanding PCB Firmware
Most hard drive circuit boards possess ROM, NV-RAM, or a controller bit that holds unique information required to access the difficult drive organization area. We call this data "PCB firmware". If PCB firmware is missing or incorrect, at that place is no access to the hard drive, and no access to user information. Considering of this, a simple circuit board swap will not make a faulty hard drive operational. It may be necessary to transfer the PCB firmware onto a new PCB.
In many cases, the ROM or NV-RAM chip is external, and can exist physically transferred (soldered) onto a new circuit board. The PCB replacement guide explains how to do this yourself. Sometimes the PCB firmware is located on the controller scrap, and without a professional BGA Rework Station, information technology is impossible to motion that flake onto a new PCB. That same controller chip is often the trouble in the original PCB. In these cases, a new chip must be reprogrammed with the correct PCB firmware (which Donor Drives can generate) with access to the original failed difficult drive.
Step 2. Hard Drive Diagnostics
There are often many complications subsequently a power surge, including a burned pre-amplifier, which is considered to exist a mechanical failure related to caput disk assembly
i. Cheque the hard bulldoze cables. We always recommend using a toaster-similar external enclosure for testing purposes. It is very easy to piece of work with, and allows easy access to the difficult drive while it operates, improving your ability to properly diagnose hard bulldoze behavior.
ii. Does your hard bulldoze spin? Effort to mind, touch it, or carefully lift it. If it makes a buzzing audio or a sound like it is trying to spin, the failure is well-nigh likely a spindle seizure and has nothing to do with the circuit board. If you hear a tick, or do not hear or feel any move, the PCB is probably defective.
3. If the difficult drive spins, attempt to decipher if it makes a tranquility ticking or clicking audio. Does it spin for a while and so slow down? Such behavior indicates a head crash, and is rarely a PCB problem.
4. For a ordinarily performance hard drive that is not recognized by your computer, the effect could be anything, including circuit board failure, bad sectors, firmware, or whatsoever mechanical issue. Determine if the hard drive is recognized by BIOS with correct parameters. If it is, then it is probably a firmware or logical hard drive failure, not a circuit lath defect.
5. Proceed with Donor Drives Circuit Board Bandy Guide if you lot believe the PCB is faulty..
Step 3. Finding Replacement PCB
Finding a matching PCB for your hard bulldoze tin exist difficult if the failed difficult drive is rare; all the same, nearly of our customers tin can discover a match by following our Donor PCB Matching Article.
Step 4. Brand-Specific Replacement
Western Digital.
WD has 2 types of PCBs.
Type i has an 8-legged U12 ROM chip that must be swapped. Come across Step 4 of this Circuit Board Replacement Guide.
Type 2 has a missing U12 chip, and PCB firmware is stored in the big "M" Marvell Controller Chip. That chip can exist transferred by a professional with a BGA Rework Station, or reprogrammed by Donor Drives.
Seagate.
These difficult drives have 2 architectures: Barracuda (older) and F3 (new generation).
Barracuda Architecture. These hard drives take a dot (.) in the firmware version ("3.CDA", "eight.01", "3.03", etc.). Near PCB swaps are uncomplicated (~85%). In the other 15%, a ROM chip must exist swapped.
F3 Architecture.Difficult drives have no dot (.) in the firmware version ("CC44", "0005HPM1", "SD01", etc.). The 8-legged firmware fleck will take a number starting with 25, and must be transferred to a new circuit board. See Stride 4 of this Circuit Board Replacement Guide.
Notation: If your hard bulldoze has a new PCB recognized by incorrect parameters (such as wrong model, different SN, or incorrect firmware), a computer electronics professional person or Donor Drives, LLC must swap the chip.
Toshiba.
Nigh Toshiba boards have an 8-legged firmware flake that must exist swapped. The fleck will take a number starting with 25. See Step 4 of this Circuit Board Replacement Guide.
For some Toshiba families, the chip might be missing unique adaptive data stored in the large controller flake. That chip can exist transferred by a professional with a BGA Rework Station, or reprogrammed by Donor Drives.
Hitachi and IBM.
All Hitachi and IBM circuit boards have an eight-legged firmware scrap that has a number starting with 25. See Footstep four of this Circuit Lath Replacement Guide.
Maxtor.
Adaptation service not required. A uncomplicated PCB replacement should work.
Samsung.
Most of the time there is no need for accommodation service, but in some cases an 8-legged firmware chip (with a number starting with 25) must exist transferred. Run across Step iv of this Circuit Lath Replacement Guide.
Fujitsu.
PCB adaptation is not required, but occasionally, a firmware scrap transfer is required. See Stride iv of thisCircuit Board Replacement Guide.
Footstep 4. Example of PCB Replacement
Make certain the PCB Replacement is relative and that PCB firmware needs to be transferred. Read our guide advisedly for instructions.
Examine your hard drive circuit board to see if a ROM chip exists. The ROM is usually an eight-pin bit (4-pins on 2 sides) marked every bit U12 on Western Digital, or U6 or U5 on Hitachi. There is normally only one eight-pin bit on a difficult bulldoze circuit board. You will probable discover a number starting with 25 on the flake. Western Digital USB-powered PCBs and some newer, big-capacity Hitachi difficult drives take 2 ROM fries, and then experience free to bandy both.
If you aren't sure which chip to swap, contact us, and we will gladly help. For Western Digital PCBs, detect a U12 white marking on the flake side of the circuit board. A missing chip in place of U12 would indicate that the PCB firmware is embedded in the controller chip. That chip tin can be transferred by a professional with a BGA Rework Station, or reprogrammed by Donor Drives.
One time the chip has been located, perform the PCB flake swap. If you practise not feel comfortable doing information technology yourself, send information technology to u.s. for PCB Adaptation Service, or contact a local professional. Do not trust this task to a stranger—this chip is vital for data admission. An overheating ROM chip can consequence in significant damage and data loss.
If you lot have soldering experience and the required tools, you lot can endeavor this at your own risk. The required tools are: a hot air station or heat gun, metal tweezers, grip tool, and an optional soldering flux. Brainstorm by strapping the new board to a table with the chip ready. You tin apply tiny bits of soldering flux on all eight pins of the flake if you lot want. Turn the heat gun or air station to high temperature and airflow settings. With one hand, hold the air-generating end a half-inch away from the chip for 10-15 seconds, while the other paw has the tweezers ready to remove the scrap. Remove heat simply a bit from the chip, and try to lift it with the tweezers. Do not tear the ROM chip from the PCB—information technology should come off with no force. Echo this with the original ROM chip. Brand sure to recollect which side of the scrap was on the lath. There is a dot on both chips and PCBs in case yous forget which side was on the board. Next, align the ROM chip from the former board on the new board. Utilise heat for x-12 seconds, remove heat, and absurd the board. Brand sure that the ROM chip sits tightly in identify. Now you tin can attempt plugging in your difficult drive.
If hard drive still does non spin:
one. There might be a different issue, such as a seized spindle.
2. For some modern WD drives, there could be a failed HDA preamplifier.
3. Yous oasis't fully soldered the chip. Cheque that all legs take a adept connection to the PCB.
4. The chip was soldered on the wrong side.
5. The scrap was damaged while soldering.
