Seagate Barracuda 7200-11 Hard Drive Recovery

By now most of you have heard about the problems that a firmware upgrade has caused with the Seagate Barracuda 7200.11 hard drive line. Both 500 GB and 1 TB hard drives have just stopped working without notice. After the drive up and dies and you re-boot your computer, it goes into a fail safe mode and is not recognized by your BIOS anymore. This article will help you identify if you need hard drive recovery on your Seagate Barracuda 7200.11.

Model numbers of Seagate Barracuda hard drives that have firmware problems (note the bolded 3):
1000 GB
ST31000340AS hard drive recovery

750 GB
ST3750330AS hard drive recovery

500 GB
ST3500320AS hard drive recovery

Challenges Hard Drive Manufacturers Face

Seagate is just the latest victim in the war going on between storage companies. Between lower prices than ever for storage and consumers growing needs for capacity, these hard drive companies are finding it harder than ever to put out a stable product for a reasonable price.

These emerging technologies are still happening now with the advent of high capacity solid state storage, digital data storage without moving parts is the future of backup, the question is: when will the price per MB of flash media and solid state storage change to price per GB?  As far as traditional storage with moving parts i.e. hard disk drives, there has been an explosion of emerging technologies there as well. The release of perpendicular recording was just the first step in the process that has led us to affordable high capacity drives like Seagate’s Barracuda 7200.11.

What To Do If Your Seagate Barracuda 7200.11 Needs Hard Drive Recovery

If you own a Seagate Barracuda 7200.11 500 GB or 1 TB hard drive, what should you do? The first thing is to get a comparable capacity external hard drive and transfer all your data to it ASAP. By using a FireWire or USB external hard drive, you can add storage without restarting your computer. If you are not sure what type of hard drive or what model hard drive you have, there are ways for you to check that out without restarting your computer or looking inside of it.

Step 1 – Right Click On My Computer and choose MANAGE

Step 2 – Choose DEVICE MANAGER in the left window

Step 3 – Expand DISK DRIVES in right window

You should see the hard drive model number in this screen, if you don’t, highlight each drive individually and choose properties to see details on your hard drives.

Step 4 – Choose hard drive in question, right click, and choose properties (if necessary)

If your Seagate Barracuda 7200.11 has failed and you need Seagate harddrive data recovery call us at 727-345-9665 or visit our page: Hard Drive Recovery.

    I have the same problem as you mentioned in this article. One day my pc is restarting again and again, so I switched it off. then started again but pc is not booting. I thought that OS is crashed. I tried to installed the Windows Xp with SP2 but when getting the harddisk option there are not partitions as earlier there are 4 partitions. Also I am not able to format the harddisk. I was getting the message that harddisk is not accessible.

    I purchased new harddisk and installed Windows XP. Configure the old harddisk as slave. In device manager I am able to see the harddisk and also the status is working properly.
    But when clicked on Volumes, I was got the following message:

    Disk Disk1
    Type Unknown
    Status Unreadable
    Partition Style Not Applicable
    Capacity 0Mb

    Also in Disk Management, I am getting new harddisk information, not getting the old information. My old disk has approx. 60Gb Data. I want to recover only some of the data.

    Please help me to recover the data.

    Thanking You.

      V. Venkat,

      Ok It sounds like file system corruption, due to what I can not be sure. The boot loop could have been cause by many things, but more often then not a virus. If you would like I can remote in to your computer and take a look at the drive let you know what it wrong. So we can at least get you on right the path to getting the data off.

  2. Puzzled March 5, 2009 12:23 pm #

    Regarding the Seagate problem. Check the serial number of the drive to see if it is affected with the buggy firmware.

    By all means copy the data to a new hard drive.

    If the firmware has not be update then the drives can be afflectected in two ways. One is a Busy state which prevents the computer BIOS from displaying the drive in the POST screen upon bootup. The oher problem is that the drive’s capacity is shown as 0GB. I would contact Seagate support first since if Seaate determines that the firmware is at fault they will recover the data and send the fixed drive back to you w/o charge.

    how recover to jpg file after formating

  4. Joseph Whitehead March 14, 2009 2:07 am #

    It makes a huge difference in rather the BIOS won’t detect the drive, or if Windows can’t find the partitions. One is a lot more expensive to fix since you have to send the drive in if it won’t even be detected by the motherboard’s firmware. It sounds like you need to have them do a remote restoration service. Hopefully, it’s just Windows that can’t see the data.

    i built my first computer 6 months ago with the help of “my computer dork”. i have the barracuda 7200.11 1000Gbytes and it just all of sudden crashed. the only thing i noticed was the picture was slightly glitchy maybe only a few minutes before the “oh no”. i just thought it was my wireless conection. my buddy knew instantly that it was f@#&ed off when he manually rebooted the computer and it said “insert boot disk and press enter”. then he went into the computer by pressing delete right after start up. my computer wasnt recognizeing my hard drive after changing the cables it still did nothing. so he pluged his drive up in that bitchand it saw it. i just got the fax from seagate about the recovery process. IF ANYONE HAS ANY HELPFULL KNOWLEDGE PLEASE E-MAIL ME SOON . theres no telling how bad those F&!$s will rape me and still get nothing from it but a sore ass.

      Can the hard drive be seen by another computer when hooked up as a slave? If so we can remote in and recover the files. Also can you post the full drive number i.e. ST31000340AS

  7. Smiddy33 July 5, 2009 8:29 am #

    Hey hey i have the seagate barracuda 1000GB serial ST31000333AS and the other day it just stopped working, i noticed when i went to play music and it has my music n some games on it. i then restarted my compy, n went into bios and my bios couldn’t detect it…

    After going through switching cables and even dismantling and rebuilding my compy bios still did not see it, i then loaded windows as normal, and found that windows can detect it, my bios cant, and when im in device manager, in properties of the HDD im getting the following msg in the volumes tab:

    Disk: Disk 2
    Type: Unknown
    Status: Unreadable
    Partition Style: Not Applicable
    Capacity: 0 MB
    Unallocated Space: 0 MB
    Reserved Space: 0 MB

    Is anyone able to help me get the HDD working again, or atleast recover the data so i can back it up ?

    • DTI Data Recovery July 7, 2009 12:51 pm #

      The drive is Bricked which in English means it has an overflow in of errors do to malfunctioning ondisk firmware. The service area of the drive is now corrupt you can try seagates firmware fix but that is more of a preventative fix to a problem than an after the fact crash remedy. More than likely the necessary measures to fix this problem will need to be addressed by a company specializing in data recovery as the Service Area of the drive has become corrupt.

      Service Area- The firmware on the Printed Circuit Board (PCB) is a roadmap to the real firmware which is located on the platters of the drive. The Service Area (SA) contains defects list both at the time of manufacturing, grown defects lists while in use, overlays, adaptive info, Drive ID, all the info the drive needs to run.

    Hi, I’m hoping someone can help. I have the Seagate 7200.11 ST3500320AS 500GB HDD. I noticed my PC running sluggishly and then a few days later I get an I/O error when trying to read the drive. The BIOS recognizes the drive every time I boot (now the drive is hooked up via an external USB enclosure).

    Whenever I turn the drive on (in the USB enclosure), the PC takes forever to recognize it. Device manager recognizes it as “ST350032 OAS USB Device” and thinks it is running properly.

    If I plug the drive into the MB and boot, the BIOS recognizes the drive and gives it the correct capacity, LZone, etc.

    But Explorer sees the drive as a generic drive “Drive I” and there is no data.

    The drive spins up very quietly, no vibration or clicking.

    I have upgraded the firmware, but that didn’t help.

    Any ideas?

    I was thinking about finding another drive and swapping PDB’s.

    Of course, I wouldn’t care about this drive failing if I had backed up my data, which I didn’t.


    • DTI Data Recovery July 21, 2009 3:19 pm #

      Steve, this was emailed to me by an engineer familiar with the Seagate issues:

      This is NOT a firmware issue sounds like on of the heads is having trouble reading. The major indication would be the IO error drives that are bricked do not do this. I would clone the drive in DOS using any DOS based tool as Windows tries to read each sector multiple times; therefore, if the drive is having trouble reading it just makes it worse. Use Speed Clone or any other DOS base tool to clone to another working drive.

    If you need to recover your files I used NTFS FOR DOS and xxcopy installed on a thumb drive and used a usb external drive and managed to recover my files these programs are free it takes a while to recover depending on the amout of data so be patient
    you have to know the old dos commands

    here’s my problem with my ST31000340AS, i am trying to run the new firmware for the drive hoping it wold fix it. my ST31000340AS Seagate Drive is not my master drive, if i run the firmware using my master drive and my ST31000340AS Drive as a Slave Drive, after system restarts, it wouldnt do the update since (i guess) its not the Master Drive of the system.

    any ideas on how to fix it or how to run the firmware?

    much thanks!

    • Jacqui Best September 22, 2009 11:05 am #


      I guess the first question would be what is wrong with the drive? As far as it not being the master drive have you tried unplugging the other drive completely from the machine while you try this process it would be bad to firmware revise the wrong drive. Unplugging the unaffected drive would make this situation much more safe.

    Recently my barracuda 7200 has had errors. The bios sort of gets stuck in a loop, you can hear it making a recurring loading sound, and the cursor freezes up every 5 seconds or so. Is there anything I can do about this short of buying a new one?

  12. Alex December 13, 2009 4:37 pm #

    My Seagate Barracuda 7200.7 stopped working.
    The initial symptom: Windows froze
    After reboot th BIOS does not recognize the drive any more.
    Drove is quietly ticking.
    When I hooked it as a slave to another computer, the computer stopped recognizing both drives.
    Any idea?

    hello gud mng

    i bought seagate ST3500418AS 500GB hard disk 2 years back .
    i formatted my pc for around 20 times .
    recently my pc started showing

    what does this mean
    and a message saying that please back up ur files is repeatedly appearing on my desk top

    and some times even my hard disk is not being detected and when i un plug ht power chord and plug it it works
    what might be the problem

    is this my disk failure ??

    should i buy a new one?

    • David Mohyla July 18, 2012 12:58 pm #

      I would back up all data from this drive in the event the hard drive is going bad. Any time smart is starting to give warnings it is probably time to move on to another hard drive. The drive may continue working for a long period of time without any failure. However, always better not to risk losing data.

  18. lucas November 7, 2010 2:56 am #

    i have question relatined to seagate… i need to recover data from a 80g seagate i want to put it as a slave on my seagate 250g do i need to put a jumper ? ty

  19. Jacqui Best November 10, 2010 3:37 pm #


    It depends are you going to put it on the same IDE cable? If so then yes. If this is SATA then no just hook it to the second SATA connection.
