Re: Data Recovery

rooted? Is that default when you buy any phone?

You can flash the firmware with the phone itself without another machine?

No root needed if it's signed..... Also, some phones are pre rooted. take oneplus line of devices for example.

Re: Data Recovery

did you look for a window old folder?
otherwise hope the new install didnt overwrite anything important as it is gone for good unless you are a tla with unlimited budget.tell them to stop messing with it till you run recovery software as every disk write threatens the remaining recoverable data.
as for why the methods are not talked about the reason is that most folks will not be able to do many of these operations safely and will make a bigger mess.some of the customer recovery attempts that i have gotten shipped to me should be listed by the D.O.D under methods of data sanitation when you dont have time for a guttman wipe.and those of us who develop ways to repair faults in drives to recover the data wont give away our work free.would you give away your paycheck?

Re: Data Recovery

But the backup drive is never left hot in a system, except when backing up/recovering.

Arguably you shouldn't even do that, Murphy will get you when the PSU blows up and takes out both drives.

Use 2 separate computers and copy across network.

Call it the PEBCAK wipe?

Re: Data Recovery

yes.like getting a tottaly dissasembled drive in a baggie that had been shipped from singapore in a bubble mailer.at least it was a common single platter unit and was an easy save in spite of the owners attempt to trash it.
or one that was "cleaned" with sandpaper and brillo pads.told the guy to keep it unless he wanted it used as an example of what not to do to a drive containing irreplaceable data.
hard to recover anything from dust around his place.and i doubt a tla could do anything with it regardless of budget!

Re: Data Recovery

I recommend DMDE. The freeware version has an excellent disc editor and can recover a lot of damaged drives. The full version (US$20) is a powerful data recovery tool.

http://dmde.com/

In the disc editor, go to sector 0 and drag your cursor down the vertical scrollbar. If every sector (past the formatted area at the beginning) is full of zeros, then the drive will have been wiped. Otherwise the data should still be there.

If you have removed the drive from an external enclosure and installed it inside your computer, then be aware that some external drives (eg WD My Book Essentials) are hardware encrypted. The USB-SATA bridge PCB inside the enclosure handles the encryption/decryption. If you install such a drive inside your PC, all you will see will be gibberish. Furthermore, WD and Seagate external 3TB+ drives use 4KB sectoring. If you install such a drive inside your PC, you will expose its native 512B sectoring and render the file system inaccessible. Essentially you will have a 4Kn file system on a 512e drive.

PhotoRec (freeware) searches for files on the basis of their headers. For example, JPEGs may have "JFIF" text in the header while GIF files begin with "GIF89a". Usually such files will be recovered without file names. That's because the original MFT will have been destroyed by the formatting process.

Data recovery professionals recommend R-Studio and UFS Explorer. Some use GetDataBack.

The freeware version of DMDE will allow you to perform an NTFS search. This will find all remnants of the previous file system. You will be able to recover a limited amount of data, but at least you will see whether recovery is possible.

DMDE did a good enough job; the 'free' limitation of 4k files just means that you have to select all, recover 4k, it will automatically deselect those 4k files so you can continue recovering them 4k at a time.

That combined with EaseUS Data Wizard did fairly well. I ended up just giving the user an external harddrive with every image file I could find, 70% of it being corrupted, rubbish data. Lots of good stuff in there though.

Told the user they had to painstakingly go through every folder and the 100's of thousands of files recovered and manually pick out the good data. Figured it would be a good lesson to call me *before* it all goes wrong next time.

omgwtfbbq that sounds familiar... remember reading about something like that in my local computer hardware forum. i can also tell u that it wasnt me. i may be a nub but i'm not that big of a nub.

i also read another story in my local forums of a guy who wanted to open up his hard drive to fix whatever was wrong with it. the pros told him dont! not unless u have a cleanroom. then he insisted that his room was very clean and very well cleaned (by his mother, i'd bet...) and went ahead and opened his hard drive anyway. "oh my hard drive has a broken head. no wonder it wouldnt work!", he says. :S boy i cant describe how hot he got flamed on the forums for that.

moral of these stories, dont even think u can fix a hard drive by dicking around with it. u just dont... pfft...
