20 Most Recent Seagate Barracuda 7200.7 Plus (ST3120026A) 120 GB Hard Drive Questions & Answers

No fuse. Just control electronics.

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your motherboard to your hard drive make sure they have a secure connection and are not faulty or just replace them there probably old and faulty

Just pointing that out.

From my own small piece of advice, I would replace the circuit board with one from another Seagate 7200.9 Barracuda Plus 120GB harddrive. Buy a good used one.

This way you can install the circuit board on the one you want to retrieve data from, then reinstall it back on the one you bought, after you have retrieved your data, and have a working Harddrive.

Buying just that circuit board? Mmmm, no.

Just from a quick search,

Information on Harddrives,

Do I know if the damage has gone further than just the circuit board? No, I do not.
Therefore it is a decision only you can make if it is worth the money spent.
There are also professional data recovery services. ($$$$$)

For the Seagate hard disk model ST3120827AS, the TVS diode is typically located on the circuit board (PCB). TVS diodes are designed to protect electronic circuits from voltage spikes and transient events. They are usually small, with two leads, and look like small cylindrical or rectangular components.To locate the TVS diode on the circuit board, you may need to refer to the hard drive's datasheet or schematic diagram, if available. Additionally, you can try searching for online resources or forums where individuals share information about hard drive components and their locations.Regarding the Cisco Nexus Network Switch , it's important to note that specific details about the internal components, including the location of TVS diodes, may be proprietary and not readily available in publicly accessible documents. For detailed information about the switch's internal components, you may need to refer to Cisco's official documentation or contact Cisco's supporthttps://www.serverblink.com/n3k-c31108pc-v-cisco-nexus-network-switch/

Try downloading TESTDISK and see if the drive is detected on the List within TESTDISK. If it is then you may be able to restore the boot sector within TESTDISK.

You will need an external Hard drive adapter case. This will probably come with driver disk. If already and external drive it may have internal firmware which talks directly to the PC. Just install drivers, if any, and plug unit in. Follow screen prompts.

You do not say what OS you were installing, and Windows limits what you can do with the hard drive during installation. As you have found out, any power interruption during an installation will likely corrupt the process and make the system unbootable. If you can restart the install at the very beginning that may work for you. However, I believe the simplest fix will be to use a live system bootable disk and erase the corrupted partition table on the drive then restart the install as if it were a brand new hard drive. For that type of recovery I use gparted, which can be downloaded for free from http://gparted.org/livecd.php Gparted live can be used on CD, hard disk, USB, or even pxe boot. I would delete all the existing partitions that were created during the failed install, then restart the install from the very beginning as if it were a new disk.

The hard disk must have crashed and only professional data recovery service providers can retrieve data from the hard disk. It will cost money and if the data is extremely important then only you should opt for data recovery.

You mean "lost" photos? or I don't understand your question. If lost, there are a number of "free" recovery software solutions as well as purchase type solutions. Otherwise, tomshardware.com has very good answers.

The picture is in the wrong format, try Jpeg.

Hi, two things to try. 1. If you have the Win7 cd/dvd, go here and read: http://www.bleepingcomputer.com/tutorials/start-the-windows-7-recovery-environment/ But I'm thinking that you have a few bad sectors in the HD's boot area (educed from your tzak.tzak description - which is head seek (bang) trying to find the boot sectors). Which I'm not sure that Win7 recovery can cope with. But check out this link and read/follow links: https://answers.microsoft.com/en-us/windows/forum/windows_7-system/how-to-fix-the-boot-sector-of-windows-7/deb6ad12-a6b1-46fc-9786-240f66f9143e And this link (better?): https://answers.microsoft.com/en-us/windows/forum/windows_7-system/restoring-windows-7s-master-boot-sector-to/435f7bf7-9d5b-4741-9746-945ff06e6251 or 2. Go here and get SystemRescueCd: http://www.sysresccd.org/SystemRescueCd_Homepage It contains many tools for the repair of malfed systems. You will want to use this tool: TestDisk TestDisk[4] Popular disk recovery software. Recovers lost partitions and repairs unbootable systems by repairing boot sectors. It can also be used to recover deleted files from FAT, NTFS and ext2 filesystems. File system recovery is supported for reiserfs, ntfs, fat32, ext2/3 and many others. In closing, I would get a new HD, maybe a SSD? to replace your original hard drive (It may be failing, or it took a hard knock while in the boot phase, causing head-bang in the boot sector - not good). Make the new drive your master and use the old one for misc. data that you have originals of, i.e. music cd's, dvd movies, programs off-loaded from Tivo/DVR, etc. Hope this at least gets you going in the right direction...

Backup data and replace drive ASAP.

Pry open and try connect SATA drive to motherboard directly.

You'll need to restart the formatting and installation of the OS.

I understand the value of the files that resides on the disk:) Yes! It is possible that harddisk may back to life by replacing the logic board but of the same model or part number. If it is not possible by replacing logic board due to other defects such as head crash and spindle drive motor opened/shorted, there still a big chance to recover depending how you value the data on it by contacting international Seagate Data Recovery support service with considerable service fee. Hope this helps.
