The machine refused to start, and the client needed to recover the system files without which the lathe would not run. A drive from the year 2000 with a mere 6 GB of capacity and an IDE interface belongs to a class of technology that is no longer routinely repaired — but such cases are not uncommon in our lab.

We deal with mechanical damage every day – but not every drive arrives in its original state. This one had already been opened by someone before it reached us, and the situation was far from ideal.

The second scenario brought a Patriot P210 with 512 GB capacity to our lab. The customer described a situation where the drive would initialize correctly, but after reading roughly half a gigabyte of data it stopped responding. A classic symptom of NAND memory degradation.

The quote he received there – high price, long turnaround, 95% success rate – led him to seek a second opinion. When we connected the drive, it showed no response whatsoever. As far as the diagnostic system was concerned, the drive simply wasn't there.

But between the initial shock of a locked screen and the actual state of data on the drive, there's often a huge difference. In this article, we'll show you from a data recovery lab's perspective when data can be saved, when it's too late – and most importantly, what to do in the first minutes and what to absolutely avoid.

It powered on, displayed the logo, and a few seconds later restarted on its own. Over and over, in an endless loop. The owner was primarily concerned about photos and videos that were completely inaccessible in this state.

No drop, no clicking, no visible damage. But their owner discovered he had nowhere to plug them in – the interface that once powered the majority of home and professional computers has completely vanished from today's machines.

What now? In this article, we'll show you – from the perspective of data recovery specialists – how to properly assess the situation, when it makes sense to attempt recovery on your own, and when every further attempt reduces the chances of saving your data. We draw on thousands of cases that pass through our laboratory every year.

The owner tried to fix the situation himself – he formatted one of the drives – but instead of a fix, data access became completely impossible. This case illustrates well why it's better not to make hasty decisions when dealing with RAID arrays.
