This document discusses troubleshooting a failed hard drive. It begins by explaining that hard drive failures are a common cause of Windows errors. It then provides several methods for troubleshooting a failed hard drive, including using the CHKDSK tool to check for errors, attempting data recovery if files need to be saved, completely reformatting and erasing the drive if Windows won't boot, and considering the drive failed if mechanical components like the actuator have broken.

malware or other software error. If you’ve gone through all of the proper troubleshooting steps regarding PC viruses and other
Windows software, but still are getting an error with the operating system, it may be due to a failing or erroneous hard drive.
If any PC part is to fail, or at least cause errors within the Windows OS, it’s most likely the hard drive. Sometimes, PC parts can
fail without notice, leaving Windows in a non-functional state or with poor performance or random errors. In today’s article, we

Hard drives are one of the most common computer parts that fail without notice. Additionally, hard drive errors can cause
many types of Windows errors.

In most cases, the internal and primary hard drive for a PC will be the Local Disk (C:) drive. However, it may be different
depending on your PC’s drive setup. From the Computer pane, locate the PC’s hard drive and right-click it. From the
context menu, select the option P rop e rtie s.

2. Click the T ools tab and select the Che ck now option to check the hard drive for errors.
Ca n’t Boot Into Wind ows
If you cannot boot into Windows, then you also have the option of running the CHKDSK function (mentioned above), from
Windows Recovery Console. You will need a functional PC with Windows to create a System Repair Disc. As Microsoft notes,
creating a System Repair Disc can be done using the following steps:

3. Upon booting from the system repair disc, you can run CHKDSK, but additionally, the disc has a few other utilities that can
help repair and troubleshoot a Windows operating system that will not boot. Remember, for failed or erroneous hard drives,
the objective is to be able to boot into Windows so that you can backup any important files or data from the drive.
Da ta R e cove ry
If none of the above options are suitable, then you can also attempt data recovery, if the hard drive has important files or data
that you absolutely need. Data recovery is a bit more work, but it can be worth it in some situations.
Data recovery is complex, and can involve advanced drive troubleshooting using fdisk and commonly, specialty recovery
software. If the hard drive has errors, is completely corrupt and won’t boot into Windows, you may be able to recover files
simply by removing the drive from the PC and using a hard drive enclosure to connect the drive externally to an existing
Windows PC. From there, you may be able to use specialty software to manually browse the Windows based disk using file
structure, and manually move important files or data to another drive.
Additionally, to learn more about hard drives and complex data recovery options, you may want to check out PCStats
Beginner’s Guide to Hard Drive Recovery (http://www.pcstats.com/articleview.cfm?articleID=1139).
Comp le te R e forma t a nd E ra se
In a scenario where Windows won’t boot and even the System Repair option fails to fix the hard drive, you should consider
performing a complete reformat and erase, before considering the drive to be a vegetable and throwing it to the garbage. In
some cases, such as a complex rootkit virus, Windows may have system level errors, in which a hard drive format is the best
option.
To completely format and erase an internal PC hard drive, you can create a bootable formatting disc. For this, you may want
to check out DBAN (http://www.dban.org/), or Darik’s Boot and Nuke. Upon booting from a DBAN disc, you can wipe the
primary PC hard drive using some basic command line.
A fa ile d Ha rd Drive
Worst case scenario is a completely failed hard drive that may have a failed spindle, arm or platter.

4. In a case where the actuator/arm or other mechanical component has failed, you may want to consider the drive to be done
with. However, if you have extremely important data on the drive, and the platters are still intact and undamaged, you may be
able to swap the platters to an identical drive and repair the drive, which would ultimately give you the option to recover your
PC data.
This requires an advanced technical understanding of hard drives, calibration and more. So, in most cases, it would be better
to have a tech or data recovery specialist do this, rather than attempt it yourself.
Those are a few ways that you can troubleshoot, recover, diagnose and fix hard drive errors and failed hard drives. Thank
you for stopping by the site for today’s post. Enjoy!
