Remo low level bullshit

[MrMobodies]

I found this tool claiming to recover data from drives that have been low level formatted.

See pictures at bottom.

Did you format your hard drive with low level format? You forgot take the data backup. “Oops, you have lost all the files stored on your hard drive! Because you have used low-level format, you cannot get them back at any cost. They are gone forever.” This is what most people say when you talk about data loss due to low-level formatting. However, it’s all a myth. Don’t worry; you can recover files after low level format also. But how? Remo Recover software can easily restore your data from formatted hard drive on Windows 10, Windows 8 & 8.1, Windows 7, Vista, etc. in a matter of minutes.

How Remo Recover can achieve this?

Do you know what happens when you use low level format on your hard drive? Low level formatting will erase all your data from the storage device irrespective of the number of partitions present on the device or type of the file system installed. It ignores the file system layer and directly works on the disk sectors. This is the reason why people say “you cannot retrieve files after low level formatting”. However, Remo Recover software is the most powerful tool that can go deep inside and even reach your physical disk sectors and scans the disk sector-by-sector to locate and extract your complete files from it. Thus, you can recover formatted data easily.

Best features of Remo Recover

Extra-ordinary tool which can restore you files of any type which includes 300 different types and formats lost while formatting
Can also be used to recover files from any storage devices including hard drives, external hard drives, iPods, USB flash drives, thumb drives and others
Data or files from desktop can be recovered after formatting several times
Note: As soon as you lose your files, DO NOT use the device again i.e. does not store any new files on it. STOP using the device.

Situations led to formatting:

Actually, Low level formatting is performed when you are selling your old drives or disposing your old computers. Just imagine you want to give away your thumb drive to your friend and hence, decide to format it. In the course of time, instead of selecting the drive representing the thumb drive you may accidentally choose any of the other drives containing your vital files and even do the low level formatting on the wrong drive. Some of the other reasons are:

Formatting the drive to get rid of the files that are infected with virus, without taking data backup
You may encounter some error messages when you access a file, which instructs you to perform low level formatting without which you will not be allowed to access the files
Unintentionally hit the format option instead of selecting some other option
What makes Remo Recover the best recovery tool?

Remo Recover is designed with brilliant algorithms to make the recovery process effective and comfortable. Below mentioned are a few of them:

Find Tool: After scanning or recovery process is completed, you can make use of this option to find any particular file from the list of recovered files.

Add / Edit Signature: If the signatures (i.e. file extension) you are searching for is not found in the list provided by the tool, then you can add that particular signature or can even edit the existing signature using this option

Signature Search: As mentioned above this tool can restore 300 different types of files. Hence if you want to find a particular type of file from the recovered files list after saving them on the destination location you can make use of “Signature Search” option. It uses unique signatures of the files and locates those particular files.

Save recovery Session: In case you wish to check the abilities of this tool you can make use of the demo version which is available for free. While doing this, you can save the entire scanned information using “Save recovery Session” option. Once you purchase the tool you can resume the recovery process using “Open Recovery Session” option thus avoiding the rescanning of the drive

Steps For Restoring Data After Low Level Format-
Download and install the Remo Recover software on your system
Launch the software and select the “Recover Partitions” option
Now choose the drive from where data needs to be restored and press “Scan” button
Scanning process starts and once it completes, you can view the files either by “Data view” or “File type view”
Then just view the recovered data with the help of “Preview” option
Other scenarios in which Remo Recover can be used:

Accidental File deletion using “Shift + Delete” option or emptied Recycle Bin or Trash
Failed or crashed hard drives
Hard drives having Bad sectors
Errors while partitioning the drives
File system corruption due to incomplete file transfer or abnormal system shut down
Supported File systems: Recovers files after quick formatting the drive from file systems like FAT16, FAT 32, ExFAT, NTFS, NTFS5, HFS + / HFS X

Supported operating systems: All major versions of both Windows and Macintosh Operating systems including Windows 10, 8 and Mac. If you are looking a solution to recover files after qucick formattting the drive, you can utilize this software.

I'd thought I'd give this "powerful" "extra-ordinary" tool a go to see what happens on a drive that I just low level formatted.

Nothing. No partition found. Not possible this way as I'd thought.

So powerful it can magically restore things that aren't there anymore.

It is sometimes possible to recover data from a wiped drive (albeit, not cleanly, there will be data corruption). For example, if a file has been "permanently deleted" the data is not destroyed immediately, just pointers removed. Even after a format, there can still be residual magnetization (not enough to effect normal operation) that can be detected to recover data. That's why antiviruses often come with "secure delete" functions to overwrite and scramble the data to be destroyed several times to ensure there's no trace. But recovering wiped data usually involves extensive stuff, even taking the platters out and putting them into a special drive to read traces of wiped data.

For an SSD, delete probably works the same but a format is probably a clean wipe (not sure though).

Just sounds like normal data recovery software with "low-level" errantly tacked on. Low level formatting(actually having the disc define cylinders and sectors on a platter)  hasn't been a thing that gets done outside the factory to hard drives in a good long time now. Marketing wank, but not particularly egregious to the point of calling it false advertising.

Easily restore your data from formatted. Not from low level formatted.
I see, that is how they carefully word the advert in such a way that I believe to wriggle their way out of legal trouble.

Yes, in a matter of minitues, to good to be true marketting bullshit.

That took 3 hours for a slow 500gb drive like any other recovery would take.

Since Windows 7, the default format under windows will fully write to the disk. I do not know what is written, but formatting (*not* quick format!) will wipe your data.
A quick format, if i remember correctly, just rewrites the MFT and therefore will leave recoverable items, but the files will be fragmented and jumbled, and filenames will be lost.

Nowadays, the terms (full) formatting and low level formatting are used interchangably. I don't think i have seen true low level formatting since the days of SCSI drives, and even then i'm not sure if that was an actual low level format.

The last line reveals the truth, in horrible spelling:

... If you are looking a solution to recover files after qucick formattting the drive, you can utilize this software.

I wonder if that is deliberate...

Are you sure that isn't "since before Windows 7"? I remember having to always tick the quick format box, but I also know that the last few drives I've installed (as far as I can accurately remember) had it pre-ticked.

Older versions of Windows and DOS never actually wrote over each sector, even on a full format. All it did was perform a disk check as it went. Since Windows 7, it actually zeros out each sector. There is no recovering from this using any software tool. Even hardware which is able to recover over-written data is extremely expensive and rarely works outside a lab environment.

Ah, OK!

[Nominal Animal]

Very true.  For spinny-disks, it involves analysing the analog signal from the read heads for both the payload data and the ECC data for each sector, then using all sorts of signal processing to suggest possible interpretations and statistical analysis to find out likely erased contents.  I'm not sure if and/or how it is possible/done for flash (SSDs et cetera).

They say that with extremely sensitive read heads and lots of processing, it is possible to uncover overwritten data from spinning rust: not just zeroed, overwritten with new, unrelated data.  This is ultra-expensive, and I believe requires liquid nitrogen cooled equipment (to get the signal-to-noise ratios needed).  This is why shredding – overwriting the entire drive several times over with random data – is used in security-sensitive situations.

(In olden days before journaling file systems like Ext3, Ext4, XFS, JFS, ZFS etc., one could use the shred utility to shred individual files in this fashion.  Note that you need to use a cryptographically secure PRNG, though.  With current file systems, and even with old filesystems on RAID or Flash with integrated wear levelling (SSDs, SD cards, USB memory sticks, etc.), overwriting the file does not necessarily overwrite the old file data, so only full-disk shredding is reliable nowadays.)

I believe there is no longer any such thing "low level format " that end users can do
Could be done back in the 90s?
Hard disk tolerances have been reduced to such  all amounts that initial disk formatting can only be done in the factory with a special machine . called a "servo writer "

best too use linux tool ddrescue.
Buy old hard drives on ebay to practice data recovery on - as ddrescue is unforgiving in any mistakes
ddrescue can skip past damaged parts of the hard disk and come back to it later ...
