One of the biggest problems that occur in our computer lives is to lose our critical data because of hard drive damages or failures. The best way to avoid this, is to maintain copies of your important files in more than one storage device (for example two different hard drives) and keep them offline. The second action that we can perform to protect ourselves from disk damages is to diagnose our hard drives for hardware errors.
In Windows, you can manually check the S.M.A.R.T. Status of your drives from the Command Prompt. Just right-click the Start menu, select Run, and type 'cmd' or type 'cmd' into the search bar. Drive Scope is an advanced SMART drive-testing and health-warning application.Building on the improvements to the SMART check in TechTool Pro, Drive Scope not only provides early warning when a drive is on the path to failure, but provides a deep dive into the health of the drive.
For that scope, on latest technology hard disk drives, the HDD manufacturers includes an information program about HDD health, named S.M.A.R.T. (Self Monitoring Analysis and Reporting Technology). The S.M.A.R.T. works continuously on the background and monitors a number of hard disk parameters like 'power on' hours, temperature, reallocated sector count, write error rate and much more. In this tutorial we suggest five different programs, to read the S.M.A.R.T. status on your hard drive in order to diagnose hard drive's health.

How to test and diagnose your hard drive (HDD) for hardware errors.
In this article, we suggest five (5) free disk diagnostic utilities to see the health status of your hard drive.
1. HD Tune – Free version
HD Tune is my favorite disk health tool utility and can be used to read the health status S.M.A.R.T. of your hard drive and to perform error surface scan. Unfortunately, the free version doesn't support external hard drives and isn't updated anymore.
The latest free version of HD Tune utility is V2.55 and you can download and install it from here.
How to use HD Tune:
a. Run “HD Tune” and first select the hard disk you want to diagnose (if you have more than one).
b. Then choose the “Health” tab to view HDD’s health using S.M.A.R.T. analysis. Check the “Status” column if all values are reported as “OK”. If no, then you must pay attention to your hard disk and replace it.
c. After viewing S.M.A.R.T. press the “Error Scan” tab to perform error scan in disk surface.
2. Acronis Drive Monitor (ADM)
ADM is another great tool from Acronis* that always runs on the background and alerts you for disk problems and errors (by reading S.M.A.R.T. information) in real time. The program works both with internal or external hard disks and has the ability to alert you when a problem is detected with alert messages or email.
You can download Acronis Drive Monitor from here after you complete the registration form.
How to use Acronis Drive Monitor:
1. After installing ADM, choose the disk from your available disks in the left column.
2. In “Status” column, check if all values are reported as “OK”. If no, then you must pay attention to your hard disk and replace it.
3.Modify alert settings by choosing “Critical events” in the left pane.
3. Crystal Disk Info
The Crystal Disk Info utility is able to read the health status of your hard drive using HDD S.M.A.R.T feature and monitors the temperature, power on hours, spin retries, etc. You can download and install “Crystal Disk Info” from here. Amberlight 2 1 0 – unique fractal flame generator.
The program can read the HDD S.M.A.R.T. and has the option to alert you on the health of your hard drive (internal or external) with emails or sounds.
4. SpeedFan
SpeedFan is another free HDD diagnostic tool that can check the status of your hard disk using S.M.A.R.T. You can download and install “SpeedFan” from here.
5. Sea Tools for Windows
Sea Tools for Windows (from Seagate hdd manufacturer) can test SATA, USB, 1394, ATA (PATA/IDE) or SCSI drives. The utility works with every hard drive brand e.g. Western Digital, Fujitsu, Hitachi, etc. and can check your hard disk's health using S.M.A.R.T. technology and also can perform surface tests on your disk to diagnose it for problems.
You can download “Sea Tools” for Windows from here in the download section.

- Rated Life Used : An estimate of the percentage of device life that has been used, based on the actual device usage and the manufacturer's prediction of device life. A value greater than 99 indicates that the estimated endurance has been used, but this does not necessarily indicate a device failure. Omitted if value is unknown.
- Spare Blocks Consumed Limit : Spare blocks consumed percentage limit reported by the device. When the Spare Blocks Consumed percentage for the device reaches this read-only value, Data ONTAP initiates a disk copy operation to prepare to remove the device from service. Omitted if value is unknown.
- Spare Blocks Consumed : Percentage of device spare blocks that have been used. Each device has a number of spare blocks that will be used when a data block can no longer be used to store data. This value reports what percentage of the spares have already been consumed. Omitted if value is unknown.
- Disk name.
- Name of the node.
- Data ONTAP-supplied serial number of the system disk.

- Backing adapter driver name of the initiator.
- The iSCSI name of the disk backing target. This field is valid only for iSCSI connections.
- The iSCSI IP address of the disk backing target. This field is valid only for iSCSI connections.

- Hypervisor-assigned unique ID of the backing device (disk or LUN).
- Backing disk partition number where the corresponding VM disk file resides.
- Size of the backing device (disk or LUN).
- Backing device manufacturer, for example 'FUJITSU' or 'IBM'.

- Home node name
- Physical size in human readable units
- Disk Name
- Shelf
- Bay
- Container Type
- Primary Path
- Disks are named in the form <stack-id>.<shelf>.<bay>
- Disks on multi-disk carriers are named in the form <stack-id>.<shelf>.<bay>.<lun>
- Virtual disks are named in the form <prefix>.<number>, where prefix is the storage array's prefix and number is a unique ascending number.
- Disks that are not attached to a switch are named in the form <node>:<host_adapter>.<loop_ID>. For disks with a LUN, the form is <node>:<host_adapter>.<loop_ID>L<LUN>. For instance, disk number 16 on host adapter 1a on a node named node0a is named node0a:1a.16. The same disk on LUN lun0 is named node0a:1a.16Llun0.
- Disks that are attached to a switch are named in the form <node>:<switch_name>:<switch_port>.<loop_ID>. For disks with a LUN, the form is <node>:<switch_name>:<switch_port>.<loop_ID>L<LUN>. For instance, disk number 08 on port 11 of switch fc1 on a node named node0a is named node0a:fc1:11.08. The same disk on LUN lun1 is named node0a:fc1:11.08Llun1.
Before the cluster is upgraded to Data ONTAP 8.3, the same disk can have multiple disk names, depending on how the disk is connected. For example, a disk known to a node named alpha as alpha:1a.19 can be known to a node named beta as beta:0b.37. All names are listed in the output of queries and are equally valid. To determine a disk's unique identity, run a detailed query and look for the disk's universal unique identifier (UUID) or serial number.
