How to restore data from a hard drive


hello and welcome to this hard drive data recovery video now the drive we are going to try and recover the data from is this laptop hard drive now when you're repairing a hard drive the first thing to do is have a listen to how it sounds because that can tell a lot about what's actually wrong with it. so let's plug this into an external drive enclosure and see what kind of sound it makes so as you can hear that does not sound very promising for our little hard drive now to me it sounds like it'shaving trouble spinning up this is what hard drive should sound like and this clearly did not sound like that so what that says to me is that perhaps the motor has gone but I think the more likely reason.

for it not spinning up is that the hard drive heads have gotten stuck on the hard drive platter which is preventing it from starting to spin so the first thing you can try is hit it sideways onto a table surface you can try it whilst it's trying to spin up because it can actually help to get the heads loose but this can obviously cause damage so I stress and only do it if you can't afford data recovery so that's the first thing you can try.

How to do

if that doesn't work what you can try doing is what this video is actually going to be about which is opening the drive and moving the heads off the platters manually so to open a drive you need a set of Torx screwdriver bits and a screwdriver obviously so the first thing to do is just select a screw driver bit that actually fits your screws in most laptop drives this is t6.

How The Whole Process of restore data from a hard drive Works

so that's thed rew screw driver bit I'm going to use and we can begin just to remove this topcover okay so before we start opening this drive up I must stress that ifyou're planning and doing this at homet hat you are doing it under your ownrisk because I'm not a harddrivetechnician or anything I'm just sharingmy experiences with opening up drivesand restoring the data from them okay sowith that out of the way let's beginopening this up now you've probablyheard that opening a drive in anythingbut a cleanroom causes the drive to bedestroyed basically and there is kind oftruth in this but I'm not sure how muchof it is true because I think some of itis just sort of like scare storiesspread by data recovery centers so thatthey get more sort of business but it istrue that you do want to keep justlanding inside.

here to a minimum becauseI suppose it can interfere with theheads reading the data but I don't thinkit causes anything to be destroyed itjust interferes really and so when youare opening your pure drive just makesure that you try and keep it as cleanas possible and before you put the lidback on just blow on it just to makesure that any dust that has landed on ithas been blown off but if there are someleftover bits of dust these are likelyto fly off the platter when it's thewhen the hard drive is turned on by bothcentrifugal force and by the draft thiscaused when it's on and there is alittle filter which I'll point out laterwhich does catch stray particles so it'snot too much of an issue but if you arereally concerned about stray particleslanding on the platter compromising datawhat you can do is make a clean air andclosure.

How Much Time to restore data from a hard drive Consume

which is basically just a box afan and a filter and you can open thedrive in there I might make a videolater at some point on how to make oneof these clean air enclosures and but itdoes just depend on the demand becauseit's a bit of a nichething to sort of want really anyway soonce you've gotten all the screws undonethere is usually one last screw underthe sticker and you can usually find itby scratching the surface with yourfingernail until you find an indentationand then once you find it you can stickyour screwdriver do the sticker and undoit that way so let's take a look and ifour theory was correct the hard drivehead should be on the platter which itis so as you can see the hard drive headis in the middle of the platter and itshould actually be parked just here.

which it clearly is not so what we cantry and do is manually push this intothe parked position so to do this I'mgoing to use a little hook which isactually just a dental thing and what weneed to do is just turn the hard driveplatters whilst we are pulling on thehead just to reduce the stress so alwaysturn it counterclockwise as that willensure that you don't pull the headsunderneath the actual head unit so I'vejust I'm just going to use thescrewdriver because there is a screw inthe center spindle so we can just turnthis and pull on the head[Music]and there we go as you could hear thatsounded like they were really reallystuck.

When restore data from a hard drive Is reliable to do

so I have no idea whether thisdrive is actually going to work afterbeing so stuck just check the drive forany big particles and it seems okay sowe'll just put the lid back on and bythe way this is the little filter I wastalking about and this catches anyparticles that might have landed on thehard drive platter so we'll just put thelid back on and see whether it works sonow that the hard drive is back togetherlet's get the hard drive caddy and lookat it and just see if it starts spinningand whether it is detected by theoperating system and it's worth notingthat.

I do have disk management open sothat we can see whether the drive isdetected by the computer becausesometimes it might have an incompatible driver letter and then wouldn't bemounted so we've just got diskmanagement open so that we can see alldrives that are connected to the systemso let's turn it on and hopefully let'sgo spin up oh my goodness there it isthere's the drive two hundred thirty twogigabytes detected and successfullyworking so we'll just add a drive letterto it and hopefully all the data will beaccessible so I've just added the driveletter to one of the partitions as yousaw and here are the files all on thatdrive so hopefully I'll be able to getall these off but it does look like theyare accessible see if we can go into adesktop and everything.


so I'll juststart these transferring so now thatwe've got all the data off what I'mgoing to do is just run a error scan ofthe entire surface of the drive just sothat we can see how much of it actuallyis damaged and how much is still usableso we'll just start it off right so asyou can see the scan is detecting a fewdamaged inaccessible sectors now I thinkthat these have been caused by the headactually making contact with theplatters rather than particles that werelet into the drive because it really wasquite stuck so I'm actually quitesurprised it's not worse than this butit's just worth noting that the datapercent of damaged blocks is only twopercent which means that even if it was100 percent full 98 percent of the datawould be able to be recovered which isit's a decent number.

so I hope that ifyou have had the same issue with yourhard drive that this video has beensomewhat useful in helping you to fix itnow a good look if you do attempt it andremember that it is at your own risk soI hope you enjoyed this video and if youare interested in DIY things you canperhaps check out my channel and maybesubscribe if you think it's interestingenough I'm Matt and thank you forwatching oh by the way in my next videoI think I might try transplanting somehard drive platters just to see whether
