00:00:00.160 --> 00:00:08.240
so picture this you're firing up your pc for another day of hard work or slacking

00:00:05.600 --> 00:00:12.240
off at work and nothing happens i mean the computer turns on but instead of

00:00:10.320 --> 00:00:15.759
getting to the operating system you get some kind of recurring error message

00:00:14.160 --> 00:00:21.359
about your storage then it hits you your hard drive or your

00:00:18.080 --> 00:00:23.519
SSD is dead and the data is about as

00:00:21.359 --> 00:00:28.480
accessible as the ark of the covenant but all might not be lost you can still

00:00:26.160 --> 00:00:32.960
send your drive off to a data recovery service so that your tax documents

00:00:30.480 --> 00:00:37.200
personal photos or saved games aren't lost to the ether but how do you even

00:00:34.960 --> 00:00:40.000
get started with that well today we're going to tell you how and we'd also like

00:00:38.640 --> 00:00:44.399
to thank our friends over at drive savers for sponsoring this video

00:00:42.559 --> 00:00:48.320
first things first if you use a professional service it probably won't

00:00:46.399 --> 00:00:53.600
take a super long time to get your data back if it is indeed recoverable but it

00:00:51.600 --> 00:00:56.239
also won't be a matter of a couple of hours before you can breathe again

00:00:55.280 --> 00:01:01.600
either if you can afford rush service and your recovery job ends up not being very

00:00:59.600 --> 00:01:06.880
complicated it could be turned around in as little as a day but you may also end

00:01:04.159 --> 00:01:11.360
up waiting around a week so keep your expectations reasonable if you only need

00:01:09.200 --> 00:01:15.520
logical data recovery the process tends to be quicker so this is when a drive is

00:01:13.680 --> 00:01:19.600
still in good shape physically but you've lost your data due to something

00:01:17.360 --> 00:01:25.119
like a problem with the operating system or an accidental format however if you

00:01:22.240 --> 00:01:28.240
have a physical issue like a head crash you might be waiting around for longer

00:01:26.960 --> 00:01:32.880
since they'll probably have to take your drive apart possibly in a clean room

00:01:30.320 --> 00:01:36.479
environment and repair the drive just enough so that there can be a chance

00:01:34.720 --> 00:01:40.880
that you can get some of that data back but how do these processes work let's

00:01:38.720 --> 00:01:44.320
first talk about logical data recovery which for example you might need if

00:01:42.479 --> 00:01:48.720
there's a problem with the master file table which serves as kind of like an

00:01:46.399 --> 00:01:52.240
index or a record of the physical locations that each file occupies on

00:01:51.119 --> 00:01:56.479
your disk issues with the mft can result in your

00:01:54.240 --> 00:02:00.159
computer simply not knowing where to find the data even though it's still on

00:01:59.119 --> 00:02:04.560
the disk so that can often still be recovered

00:02:02.479 --> 00:02:08.800
with tools that use strategies like bypassing corrupted file system

00:02:06.320 --> 00:02:12.319
infrastructure or scanning the data manually and then putting it back

00:02:10.560 --> 00:02:16.720
together using signatures that are common to certain file types physical

00:02:14.480 --> 00:02:20.800
recovery is obviously more complicated of course if a drive is very badly

00:02:18.879 --> 00:02:24.720
physically damaged there might not be anything even the best data recovery

00:02:22.720 --> 00:02:28.959
companies can do but if that isn't the case recovery companies do have a

00:02:26.720 --> 00:02:33.519
variety of tricks up their sleeves it could be repairing or replacing the

00:02:30.959 --> 00:02:37.920
drive circuit board you could move the disk platters to a new drive a tricky

00:02:36.239 --> 00:02:41.599
proposition because of how close the read and write head has to be to the

00:02:39.280 --> 00:02:45.760
platter's surface and even a drive that suffered a head crash where the head

00:02:43.440 --> 00:02:48.959
actually impacts the disc it can partially be salvaged by

00:02:47.440 --> 00:02:52.720
physically moving the head out of the way before attempting to read any data

00:02:51.040 --> 00:02:56.480
on whatever good parts of the platter are left though it should be noted that

00:02:54.560 --> 00:03:01.040
the area directly under the crash is often unrecoverable if we're talking

00:02:58.720 --> 00:03:05.760
about ssds the company might actually have to remove the nand flash that

00:03:03.440 --> 00:03:10.239
stores the data and transplant it to a new board with the original controller

00:03:07.760 --> 00:03:14.480
chip and then for corrupted firmware which also counts as physical failure by

00:03:12.560 --> 00:03:18.640
the way the data recovery company might have to repair or rebuild the firmware

00:03:17.040 --> 00:03:22.959
to access your data which can add additional time and sometimes data can

00:03:21.040 --> 00:03:27.280
be unrecoverable even if there's no physical damage as is the case of a hard

00:03:25.360 --> 00:03:30.799
drive that's overwritten with zeros or an SSD where the trim command has been

00:03:29.360 --> 00:03:34.560
run you can learn more about those things here and here

00:03:33.040 --> 00:03:40.239
now that you have an idea of how it works how do you go about picking a service provider well one thing to keep

00:03:37.599 --> 00:03:43.920
in mind is that reputable places will often provide some kind of results-based

00:03:42.319 --> 00:03:48.159
payment structure you ever see those lawyer commercials where they say you

00:03:45.760 --> 00:03:51.680
don't pay if we don't win well a good data recovery place also shouldn't be

00:03:50.000 --> 00:03:54.879
billing you if they can't get your data back so look out if they try to charge

00:03:53.680 --> 00:03:58.959
you large amounts of money that you'll be on the hook for regardless of whether

00:03:56.879 --> 00:04:02.720
anything is actually recovered and on that note make sure you get a quote in

00:04:00.480 --> 00:04:05.599
writing before signing anything also make sure that your provider has

00:04:03.840 --> 00:04:09.680
comprehensive security protocols in place they should be protecting your

00:04:07.200 --> 00:04:13.760
data and getting rid of any copies that they have once the recovery process is

00:04:11.599 --> 00:04:16.959
complete and of course like anything else read reviews and make sure there

00:04:15.680 --> 00:04:20.799
aren't an inordinate number of complaints about a particular company

00:04:18.880 --> 00:04:24.080
because they took two months and all they could recover was a big folder of

00:04:22.479 --> 00:04:29.040
Linus face memes for example not that i speak from personal

00:04:26.840 --> 00:04:32.560
experience thanks to drive savers for sponsoring this video they're a san

00:04:30.720 --> 00:04:36.800
francisco bay area based company that's been around since 1985 and is authorized

00:04:34.800 --> 00:04:42.160
by all the major drive manufacturers they offer data recovery on all kinds of

00:04:39.040 --> 00:04:44.240
devices hard drives ssds raid arrays of

00:04:42.160 --> 00:04:48.479
the aforementioned nasa's thumb drives sd cards if it holds data they can save

00:04:46.720 --> 00:04:52.080
it they even do phones all their operations are in a single data recovery

00:04:50.320 --> 00:04:56.320
lab and their data recovery advisors are available 24 7 with access to their

00:04:54.160 --> 00:05:00.240
engineers at all times meaning fast turnarounds if you're trying to save

00:04:58.000 --> 00:05:04.160
critical data they have the largest iso 5 certified data recovery clean room on

00:05:02.400 --> 00:05:07.840
earth and they offer advanced quotes free evaluation and free shipping if

00:05:06.240 --> 00:05:11.360
they don't recover any data you don't get charged so if you want to be as

00:05:09.600 --> 00:05:15.039
close to certain as you can be that you're going to get your data back send

00:05:12.960 --> 00:05:18.960
it to drive savers first before you send it somewhere else that might attempt a

00:05:16.560 --> 00:05:21.520
recovery and mess it up so even they can't get it at that point that's

00:05:20.720 --> 00:05:26.720
actually something we should have mentioned in the main body of the video one of the key important things for data

00:05:25.600 --> 00:05:31.360
recovery is if you don't know what you're doing don't do

00:05:28.639 --> 00:05:35.199
anything send it to a pro anyway use the code tech wiki to get five percent off
