Most of computer users do not know what sort of internal storage device (Hard Drive) is placed in their computer.  Typically, there are 2 types of storage devices are available.  One is a conventional mechanical hard drive made out of mostly metallic parts where data storage section constantly moving at high speed.  Another device is called SSD (Solid State Drive) mostly made out of plastic parts where there are no moving components but just like a big flash card.  (There is actually one more type available which is a combination of both.)  Make of internal storage device is so important as it holds most valuable your memory, documents and others.

Conventional type of hard drive became so cheap in price with much bigger storage capacity just comparing with a few years ago.  But this could be your worst nightmare when it fails.  All of sudden, you start hearing mechanical clicking sound coming out of the hard drive and the hard drive is no longer recognised by your computer.  Is that end of story?  Yes and No.  If mechanical parts (particularly called “seeking head”) can no longer read the data at all, only option you have is to ask forensic hard drive data recovery company to salvage your data.  You typically pay $100 to $300 for your internal hard drive but it will cost you easy $1,000 to $2,000 for data salvage as they have to reconstruct the drive itself. But still, 100% of data salvage is nearly impossible.

On the other hand, the mechanical failure is partial, there is a good chance to salvage most of your valuable data using special external start-up/recovery disk to tackle with the issue

If you require data recovery service (Sydney CBD, Sydney North Shore – particularly in Chatswood, Roseville, Lindfield, Killara, Gordon, Pymble, Turramurra, Wahroonga, Warrawee, Hornsby, Macquarie Park and St Ives area) please contact Harry 0417 424 909.  Or refer to our Service page.

Part I: Conventional Hard Drive

Very recently, one of the 3.5 inch internal conventional hard drives for data storage on my main computer stopped functioning (I will not write the make of the drive but as far as I’m concerned, I had such bad experience with this drive manufacturer in the past and this was the last drive I was using from the manufacturer).  Data storage capacity was 3TB and almost full of data.  I could hear clicking sound coming out of the drive and no matter how I tried, the drive could not be recognised by just connecting the drive to my main computer.  I took out the hard drive from my main computer and I connected the drive with my recovery computer using special external start-up/recovery disk as well as a brand new bigger capacity drive to attempt data recovery.

Fortunately, mechanical failure was partial (means could not read/write only some sections of data storage) and I could recover 99% of data.  (However, it took good 2 days)


  1. If you start hearing clicking sound from your internal storage device (hard drive) and can no longer use the drive, please stop using it as it may cause further damage and any data recovery becomes nearly impossible.
  2. Contact local computer repair specialist to diagnose the issue.

2018 Lifetime Hard Drive Stats

As a piece of mind, you should invest small amount of your money for disk monitoring utility called “Hard Disk Sentinel” which can watch the health of your internal hard drive and gives you a chance to replace (after data backup) before it’s too late.  Standard version if US$19.95 and Professional version is US$29.95.

Part II: SSD (Solid State Drive)

So far, I installed more than 100 SSD (Solid State Drive) for myself and for my clients in the past.  They say SSD is just like a rechargeable battery and it dies all of a sudden without any warning.  However, I’ve never heard any complaint of data failure from any of my client for the last 8 years.  It was expensive in the beginning but it became much more affordable with bigger capacity these days.  If you are Laptop or Notebook user where usually internal storage device is limited to one only, my suggestion is to replace (after backup) from conventional hard drive to SSD.  By replacing the drive to SSD, it will boost processing speed (at least 5 times more) with very stable working environment.  Yes, SSD could die as well but much less failure ratio than conventional hard drive.
