Are there Instances when Lost Data cannot be recovered?
Yes, there are few instances when the damage to the hard drive is so severe that data recovery is not possible.
There is neither magic power nor miracle in the real world that can recover the lost data from the scratched, extremely corrupted hard drive, or the drive with the overwritten sectors. That is why - as professional and honest as Data Lab 247 - no data recovery specialist can ever guarantee the successful recovery outcome beforehand - that is to say, before the failed drive is inspected to draw a reasonable conclusion based on diagnostic facts.
Speaking from our experience, almost every failed hard drive is recoverable when the problem is timely noticed and correct specialist is requested for help, ideally with the first signs of hard drive failure or inability to access the data. Most of unrecoverable cases happen when problem is treated in a computer repair shop, by someone who has neither the right tools nor basic knowledge (at best) in data recovery, thus most of the hard drives end up unrecoverable there - for the reason that most of the public do not distinguish the difference between computer repair and hard drive recovery. Of course, most the branded computer stores service centers have experienced technicians who aware of this problem and dispatch failed media directly to their data recovery provider, but their prices will be always two three times higher compare to Data Lab 247 rates.
It's a real puzzle why some people are obstinately delaying with the decision to seek out the professional service, or even worse – wasting time and resources over dangerous unwarranted methods for data in the desperate reviving attempts and re-runs, thereby causing the data media slow death and making its data unrecoverable. Something that can be easily avoided, if was brought to the attention of the professionals sooner
Developing Scratches on Hard Disk Platters
1. No scratches ...yet
When the drive starts failing, there are no visible scratches on the internal disk platters, covered with the thin magnetic layer with written in digital information - that is practically the DATA! The drive's platters remain clean and shiny with all intact data ...yet
2. First scratch
2. As soon the first visible scratch lands on the surface the drive is doomed to die very quickly...
This happens because the platters must spin at a high speed, typically at 5400 or 7200 RPM. That means that the heads are moving at 100 km/h (62+ mph) with very close proximity to disks. More specifically, the gap between head and disk (the flying height) is just about 10 nanometers. The more collisions with the old debris or unevenness on the surface (e.g. the first scratch), the more new scratches born and less data are recoverable.
3. Lost data forever
And finally, what we have now: Absolutely unrecoverable drive. The scratches are all over the platters, the magnetic layers (that is to say, data) are destroyed, and the filter (shown with the red arrow) turned completely black as a result of the sooty-like ferromagnetic dust deposit that coats all internal parts. The conclusion: this drive is brought down to a complete waste - beyond recoverable state.
Too late for anything:
How to prevent it?
- do not ignore the first signs of the dying hard drive;
- do not seek the solution where it can't be found, such as computer stores, shops, repair services;
- do take your failed drive to the professional data recovery, i.e. the company provides data recovery solely and nothing else!
Data Lab 247 guarantees to recover from your drive everything what is yet possibly recoverable on it and you won't be charged for our time and work in those rare and unfortunate situations when no data is recoverable or the recovery outcome is not up to your satisfaction.

Error message: cannot write to the disc because disc error occurred. Seagate ST3750630AS
This is Seagate Barracuda 7200.11 and it failed, meaning we're unable to access the drive. It was running Windows Vista and had a single partition. All data are very important and have to be recovered, but the most critical data are all QuickBooks files. The drive is more than half full, so you'll have a lot work to do. The exact location is unknown so it could be anywhere, including Program Files folder.
... your work is impeccable; we are very much pleased with the results. The turnaround time for our regular service was unexpectedly fast; we loved your flat rate policy, so there was no surprise at that end. The overall experience is scored 'excellent' grade...

I have had an HDD crash, probably a broken head or spindle as I hear clicking noises.
Dear Sirs, Many, many thanks for your help. Chris R. Gentod Switzerland
