Seagate Barracuda 7200 Data Recovery

Seagate Barracuda drives are often thought of as premium quality hard drives, which is largely true. The build quality of these drives is solid and they feel heavy and look good when compared to some other drives. They are however still susceptible to the same failures and problems which affect other hard drives.

Firmware Faults

A common problem with Seagate Barracuda drives is firmware corruption (sometimes known as SA Corruption). This is something which can be fixed without taking the drive apart, however sometimes the extent of the corruption can prevent it from being repaired at all. The usual faults are corrupt log files which prevent the drive from performing it’s usual startup routine. Once corrected, the drive can usually be accessed for long enough to extract the required data using a controlled imaging process. Sometimes further repair is required in order to continue extracting data. Corrupt firmware can be an indication that there is an underlying problem with the drive. For example, if the drive is writing hundreds of bad sectors into the S.M.A.R.T log, it is likely that there is a problem with either the heads or the disk media which is causing the errors. Although the S.M.A.R.T counters can be reset to zero, they will quickly fill up again. The best option in this case is to recover your data and scrap the old drive.

Hardware Faults

Seagate drives have been used in G4, G5 & Intel Macs from Mac Pros to iMacs and various other PCs, such as Packard Bell and Compaq machines. We now also see Seagate Barracuda drives which have been used in external USB / Firewire enclosures. This opens up a new problem which these drives were not originally built to withstand. ie. Shock. External drives can be shocked, either by being knocked over or dropped. If the drive is reading or writing at this time it could cause a head crash, as it would with most other brands of drive (although modern 2.5″ laptop drives have protection for this type of shock).  If the drive was not in use at the time of impact, the motor can still become stuck and fail to spin up. The motor spindle is attached to the hard disk casting, so the best way to gain access to these types of drives is by transplanting the disk pack into a known good casting (with a good motor).

Seagate Barracuda drives are also prone to electronic damage caused by faulty power supplies or having the power connector incorrectly inserted. It is often necessary to repair the damaged PCB, as it contains unique information which would not be present on a donor part.

We have had a lot of success recovering data from these hard disks and as long as they haven’t been dropped or knocked over, we can usually recover then externally without moving into a cleanroom.

  1. Hello,

    I own a Seagate Barracuda 7200 1TB drive that runs inside my Powermac G5.

    The drive has been running fine up until last night. The computer was put on sleep mode, then this morning it wouldn’t wake up. Tried restarting the machine a few times, and each time all I got was the \?\ blinking mac folder over a grey screen.

    At first I figured it could be a damaged OSX file or some other hardware problem (bad ram or something), so I hooked up another hard drive with osx on it, and moved the seagate drive to the secondary drive slot. The computer booted up just fine, but the seagate drive will NOT mount at all. The computer wont even show it in the disk utility.

    What can I do?

    1. Hi,
      There are various problems with Seagate 7200 drives. Some are electronic faults and others are firmware related. We have had a lot of success with recovering data from these drives. Please use the contact form on the right if you would like us to have a look at it for you.

  2. seagate barracuuda 7200.11 st3750330a8, (external usb drive)stopped working in the middle of a read, now just attempts to spin then shuts off , removed and connected to sata same outcome, still under maxtor seagate warranty before i opened up enclosure, please advise, thanks

    1. Hi Scott,
      We have seen a number of firmware issues with those types of drive. We have a good success rate with them and they are usually recoverable in our Stage 1 process.

      Let me know if you want to send it down to us. Our contact details are on the right-hand side.

  3. Hi Seagate Barracuda 7200.11 500GB – dropped it 🙁 whilst moving it from the car to the house. It now spins up but makes a clicking sound when I turn the device on.

    Can you advise if you can recover from this type of problem?


    1. Hi,
      If the drive has been dropped onto a hard surface then there are two likely problems. The first is a seized motor, however this wouldn’t usually make the drive click. The other possibility is that the read/write heads may have hit the disc surface. When this happens, it can sometimes simply damage the head, which we will need to replace. Other times, it damages the disc media too, which would leave it unrecoverable.

  4. Barracuda 7200.8 SATA : ST3250823AS

    Capacity: 250.0 GB
    Speed: 7200 rpm
    Average Read Time: 8 ms
    Cylinders: 16383
    Heads: 16
    Sectors: 63



    1. I would suspect you have at least damaged the PCB. There is also the possibility of damage to some of the more delicate internal components.

      There is no chance of a simple PCB swap, as some parameters will need to be extracted from the original PCB and written to a replacement.

      We can carry out this sort of work.
