The hard drive test I prefer to use is MHDD, you can also use the free tool from the drive manufacturer. I will post MHDD instructions in case you want to give that a try:
If a hard drive has a smart status warning or the drive is questionable this test may be of use NOTE this test does not work with AHCI or Raid sata operation. It must be done with IDE, ATA, or compatibility mode:
Before running this test it would be a good idea to backup any data that you cannot afford to lose. This test uses the hard drive at 100%. If the drive is failing or has problems it is possible for the drive to fail suddenly especially during heavy use as this test will do. It is unlikely but still I recommend backing files up to be safe. Here are the instructions to run the test:
The first step will be to burn MHDD to a disc as an image (cd preferably). MHDD Can be found here: http://hddguru.com/software/2005.10.02-MHDD/ Click the Last version of MHDD, CDROM iso-image download and burn this file directly to a disc.
TO CHANGE SATA OPERATION: (You may need to use your keyboard arrow keys and enter key if you can not click to change settings).
After burning the disc, restart the laptop and start tapping f2 or f1 or delete right away to get into the bios. There you should see System Configuration, expand that by clicking the + button (or using your arrow keys and enter key). In that list there should be something called Sata operation. (Sata Operation may also be by itself in that first screen list)
Click on sata operation and take note of the current setting to the right it will probably be set to AHCI it will need to be switched back to this after MHDD is done running. Select ATA, compatibility or ide mode and then click apply. Save and exit the bios, or if apply was the only option you can use Ctrl+Alt+Delete to restart.
COMMON BOOT MENU/BIOS keys: https://support.fixmestick.com/hc/en-us/articles/201577043-How-to-get-to-your-Boot-Menu-or-your-BIOS-settings
Now with the burned disc in the drive after a restart, start tapping (F12 Dell, Toshiba, Lenovo), (F9 HP), or (Esc HP, Samsung, Sony) on the keyboard (or change your boot options to boot to cd/dvd first). This will bring up the boot options menu. Select cd/dvd/cd-rw drive and hit enter.
If this worked correctly and booted to mhdd you should see a screen that says Microsoft windows 98 startup menu. You can let the timer run out or just hit enter on option (2 . Start computer without SCSI support).
Next you should see a new screen with numbers, most of these will not have any device listed behind them but one number should for example on my dell computer number 6 has WDC WD1600BEVT-75A23T0… and at the end a number in white which is the size of the drive.
Example: If your drive is a 500gb I would expect that number in white to be somewhere around 500,107,862,016 or close to. Find the correct drive to test then on the keyboard type the number in front of the drive (in my case it was 6) and then hit enter.
Now you should have a screen with MHDD> and a blinking cursor.
Next hit F4 on the keyboard 2 times and this will start scanning the hard drive.
You should be able to see the computer start scanning, each block represents 255 sectors (130560 bytes) on the hard drive. What we are looking for will show up on the right side of the screen.
There is a list on the right which shows numbers:
Anything below the <150ms is a slow sector or a problem sector. Slow sectors <500 or >500 will slow down the computer. If there are a lot of these one after another (several 1000 or more) the drive should probably be replaced. Also if you have any at the end that were marked as UNC this means the drive has uncorrectable errors and the hard drive should probably be replaced.
Basically if you have any sectors that are below <150 (green) let me know and if possible the total number of them.
If all of the sectors were ok and fell within the range of:
Then the hard drive is ok, if there are only a few that are slow <500 or >500 the hard drive should be ok to use.
NOTE: that if there are many slow sectors one after another or you start having error after error the drive is in bad shape and I recommend ending the test. If you have already backed up your data, you can let it run but it may take days or even weeks to finish. To end the test hit the Esc key.
