So picture, this you're firing up your pc for another day of hard work or slacking off at work and nothing happens.
I mean, the computer turns on, but instead of getting to the operating system, you get some kind of recurring error message about your storage.
Then it hits.
You your hard drive or your ssd is dead.
And the data is about as accessible as the ark of the covenant, but all might not be lost.
You can still send your drive off to a data recovery service.
So that your tax documents personal photos or saved games, aren't lost to the ether.
But how do you even get started with that? Well today, we're going to tell you how? And we'd also like to thank our friends over at drive savers for sponsoring this video, first things, first, if you use a professional service, it probably won't, take a super long time to get your data back if it is indeed recoverable.
But it also won't be a matter of a couple of hours before you can breathe again, either if you can afford rush service and your recovery job ends up not being very complicated.
It could be turned around in as little as a day.
But you may also end up waiting around a week.
So keep your expectations reasonable.
If you only need logical data recovery, the process tends to be quicker.
So this is when a drive is still in good shape physically.
But you've lost your data due to something like a problem with the operating system or an accidental format.
However, if you have a physical issue like a head crash, you might be waiting around for longer since they'll, probably have to take your drive apart possibly in a clean room environment and repair the drive just enough.
So that there can be a chance that you can get some of that data back.
But how do these processes work? Let's first talk about logical data recovery, which, for example, you might need if there's a problem with the master file table, which serves as kind of like an index or a record of the physical locations that each file occupies on your disk issues with the mft can result in your computer, simply not knowing where to find the data, even though it's still on the disk.
So that can often still be recovered with tools that use strategies like bypassing corrupted file system infrastructure or scanning the data manually.
And then putting it back together using signatures that are common to certain file types.
Physical recovery is obviously more complicated.
Of course, if a drive is very badly, physically damaged.
There might not be anything even the best data recovery.
Companies can do.
But if that isn't the case recovery companies do have a variety of tricks up their sleeves.
It could be repairing or replacing the drive circuit board.
You could move the disk platters to a new drive a tricky proposition, because of how close the read and write head has to be to the platter's surface and even a drive that suffered a head crash, where the head actually impacts the disc.
It can partially be salvaged by physically moving the head out of the way before attempting to read any data on whatever good parts of the platter are left, though it should be noted that the area directly under the crash is often unrecoverable.
If we're talking about ssds, the company might actually have to remove the nand flash that stores the data and transplant it to a new board with the original controller chip, and then for corrupted firmware, which also counts as physical failure.
By the way, the data recovery company might have to repair or rebuild the firmware to access your data, which can add additional time.
And sometimes data can be unrecoverable, even if there's no physical damage.
As is the case of a hard, drive that's overwritten with zeros, or an ssd where the trim command has been run.
You can learn more about those things here.
And here now that you have an idea of how it works.
How do you go about picking a service provider? Well, one thing to keep in mind is that reputable places will often provide some kind of results-based payment structure.
You ever see those lawyer commercials where they say you don't pay.
If we don't win, well, a good data, recovery place.
Also shouldn't be billing you if they can't get your data back so look out if they try to charge, you large amounts of money that you'll be on the hook for regardless of whether anything is actually recovered.
And on that note, make sure you get a quote in writing before signing.
Anything also make sure that your provider has comprehensive security protocols in place.
They should be protecting your data and getting rid of any copies that they have once the recovery process is complete.
And of course, like anything else read reviews and make sure there aren't an inordinate number of complaints about a particular company because they took two months and all they could recover was a big folder of linus face memes.
For example, not that I speak from personal experience.
Thanks to drive savers for sponsoring this video, they're, a san francisco bay area based company that's been around since 1985 and is authorized by all the major drive manufacturers.
They offer data recovery on all kinds of devices.
Hard drives ssds raid, arrays of the aforementioned nasa's thumb drives, sd cards if it holds data, they can save it.
They even do phones all their operations are in a single data recovery lab and their data recovery advisors are available 24 7 with access to their engineers at all times, meaning fast turnarounds if you're trying to save critical data.
They have the largest iso 5, certified data recovery, clean room on earth.
And they offer advanced quotes free evaluation and free shipping.
If they don't recover any data, you don't get charged.
So if you want to be as close to certain as you can be that you're going to get your data back, send it to drive savers first before you send it somewhere else that might attempt a recovery and mess it up.
So even they can't get it at that point that's, actually something we should have mentioned in the main body of the video.

Of course, data recovery isn't always possible. Sometimes the data storage device is corrupt or damaged, making data recovery impossible. However, data-recovery technology has become extremely advanced.How reliable is data recovery? ›
Using data recovery software is by far a much safer way to get your data back than attempting to undertake physical data recovery. But that doesn't mean that data recovery software is without its risks. While there are plenty of great data recovery programs out there, you should definitely exercise caution.What are the chances of data recovery? ›
If the loss didn't affect the file system itself, the data can be fully retrieved in its original form. Never try to recover data from a failed or failing storage on your own. This can result in permanent data loss.How long can data recovery take? ›
According to statistics, most data recovery can be completed within 1-2 days, while special or serious failures take a longer time, maybe 3-10 days. It usually takes no more than 5 hours to recover data from a 1TB hard drive, but this may vary depending on the actual situation.Is data ever truly deleted? ›
The second thing that is useful to understand about erasing data: Data cannot be erased. At least, not in the typical way that we think of erasing things, where we know all versions of a file are gone forever. There's no way to certifiably ensure that every copy of some data set is permanently gone.Does data really get deleted? ›
Basically, the answer is a bit complicated but here's the short version: you should assume that data is never truly deleted unless the device has had a complete wipe. To understand why this is this case, you need to look at how data is generally “Deleted” (and those quotes are intentional) from devices.Can data be recovered from a bad hard drive? ›
Most physical damage scenarios are irreversible and might require professional help from a hard disk recovery service like Salvagedata. However, data loss scenarios that are not caused by physical damage can be easily retrieved with hard disk data recovery software.Why is data recovery expensive? ›
There are a number of reasons why data recovery is expensive. The most common reason is that the data recovery process is very time consuming and requires specialized skills and equipment. Additionally, the cost of data recovery also includes the cost of the data storage media, which can be quite expensive.What is the most common cause of data loss? ›
Hard drive crashes account for the highest percentage of data loss, but human errors and issues with software follow closely behind. According to data from Kroll Ontrack: 67 percent of data loss is caused by hard drive crashes or system failure. 14 percent of data loss is caused by human error.How do I recover data from a hard drive that is not detecting? ›
- Download Disk Drill and open it.
- Click Drive Backup.
- Select your external hard drive, then click Byte-to-byte Backup.
- Choose where you want to store the backup, then click OK.

If you are an android user and have created a backup of your long term lost files on your cellphone, follow the below tips for help: For Android users: Go to "Settings" > Tab Back up & restore > Choose the latest backup files and click Restore from Backup to get all lost data restored.What happens during data recovery? ›
What is data recovery? Enterprise data recovery is the process of restoring lost, corrupted, accidentally deleted, or otherwise inaccessible data to its server, computer, mobile device, or storage device (or to a new device if the original device no longer works).What happens when data is recovered? ›
Data recovery is the process of restoring data that has been lost, accidentally deleted, corrupted or made inaccessible. In enterprise IT, data recovery typically refers to the restoration of data to a desktop, laptop, server or external storage system from a backup.Can you always recover data from hard drive? ›
It's definitely possible to get data from a dead hard drive. However, the drive must be recognized by the operating system and displaying the correct size. If these two conditions are met, you can attempt recovery using data recovery software.What is the success rate of SSD data recovery? ›
SSD Data Recovery Success Rate
SSDs use flash memory to store data, which makes it more challenging to recover data in case of physical damage or a software failure. However, with the right tools and techniques, a data recovery specialist can recover data from SSDs with a success rate of around 60%.
Our engineers follow strict security controls which minimize access to client data. Those controls protect our clients' privacy, and we're quite serious about adhering to them — even if engineers wanted to look through your files, they won't be able to do so without your explicit permission.Can data be recovered after wiping? ›
Technically, yes: you can recover deleted date with software – but we wouldn't recommend it. Data recovery software is not designed for the layperson – it needs to be operated by someone with appropriate training as it's often necessary to use metadata to reconstruct deleted files and return them to working order.
