How to identify the perfect hard disk?

by clippingpathindia / October 21, 2014 7:21 PM PDT

Recently I have bought a hard disk of 320GB. But I have a doubt that it is a second hand hard disk, can anyone let me know how I can identify is it new or old one? What criteria need to check before buying any hard disk?

The best way to determine of a hard drive has been used or not (or just damaged in general) is to use a hard drive scanning program. It will tell you if there are any bad clusters on the disk (bad clusters will build up over time, so a brand new hard drive SHOULD have none or close to none). I would recommend a free program such as HDDScan.

you can download a SMART reader

have it read the SMART data off the drive, see the hours used. Of course that might have been changed by whoever "refurbished" the drive.

Manufacturer's Diagnostics plus S.M.A.R.T. and the label?
by Zouch / October 24, 2014 1:43 PM PDT

The label on the disk will have a manufacturing date - that might give a clue.

Most disk manufacturers have a diagnostic program that can be downloaded from their site and run against the disk. Depending on manufacturer, these will tell you more than you ever needed to know about disks!

Or as James suggests, get a S.M.A.R.T. reader from the web and run it against the disk. That will have all sorts of data in it, usage hours and error threshold counts.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
