Data Recovery
-
@Hubtech It will. But I'm glad it's working now! If you ever get one clicking, put it in a plastic bag in the freezer for a few hours and try again. Works once in a while but it's an old trick. I've seen it work a few times.
-
Can I ask?? Is there still a possible way of recovering some files from a broken hand disk??
-
@XeL What's going on with it?
-
@ajstringham the harddisk was exhausted or in other terms burnt.. is there a way to recover file from it??
-
@XeL none! There is no way to recover data from a burnt HD.

There are many firms that do this work. It's called forensic recovery. It is very expensive but is pretty reliable.

It's actually pretty common.

depends on what you mean burned. actually burned? no. but if the drive physically died, there's a chance. I used Lazarus Data Recovery for a client way back. they have a "clean room" and physically remove the platters and reconstruct in a good HD chassis. it was 5-7K, but for him it was worth it.

FYI, it was burned from as the system overheats..

How burned? A system overheating would normally cause only very minimal damage.

Not true. How do you think they get the info off the black boxes from crashed planes? They do as @hubtech describes. Clean room and physically removing the discs, etc. It works but as @scottalanmiller said, it can be several thousand per drive.
-
@XeL This a server drive or a regular SATA drive?

I don't believe that black boxes have hard drives. That would make no sense for something designed to be so reliable.
-
@scottalanmiller Then what would they have? They store data.

Disk drives are hardly the only means of storing data. In IT we don't use spinning disks in places where resilience is needed. Not even for laptops and desktops or tablets. Seems odd that an airplane would be less reliable than an iPad.

Popular Mechanics and Purdue Uni both state that solid state is used.

@scottalanmiller Ok, well it's a disk drive just not platters.
-
Where there is the will (& funds), a recovery company can find a way.
Thought DriveSavers still had their success stories bit, but not finding it just now. Did find their YouTube channel with some tidbits—

We have a standing DriveSavers contract for encrypted drive recovery. Only needed 2-3 times. Pricy, but hope the backup process gets motivated after such expenditures.

Yes, but the physical nature of spinning disks was the issue. SSDs don't burn, not easily. You're point above was that because platters were used in airplanes that you assumed black boxes were going through forensic recovery and that that was a reliable process. But flight recorders do not use spinning rust as it is too fragile (and slow for their needs.)

Those FDRs and CVRs have to be able to withstand a lot of shock and still retain the data. Prior to using the same tech that is available in SSDs, tape was used for a long time. Basically 8-track looking things. The more moving parts, the more potential for some kind of failure.
