    Data Recovery using test folders within test partitions

    Data Recovery using DRPs on test folders within test partitions

    ** Because of Windows OS and 3rd party programs and utilities constant cycle of deleting, copying, writing, deleting, copying, writing...
    The sooner, one learns of any unwanted deletion[s], the sooner one engages any process of un-delete and/or data recovery, the better the chances of quality un-delete or recovery!
    An un-delete's or data recovery's listing of "un-deleted or recovered" folders and files does not mean each and every "un-deleted or recovered" file is actually readable and/or usable. Listing results and real un-delete/recovery can vary significantly.**
    [I have been using Resplendence's Undelux awhile now, and I remain surprised as to the busy-ness of Windows OS and 3rd party stuff constant cycle of delete, copy, write, delete, copy, write.]

    I'm starting this thread here to gather experiences from others who have attempted and succeeded in data recovery.
    This topic is not at all important or exciting -- until one needs to recover critical or important folders & files accidentally deleted or quick-formatted. I remember one poster somewhere on the 'Net indicating s/he "tried everything" with several data recovery programs -- which lead me to believe that what was displayed on the monitor did not match end-user expectations.
    [The topic title reflects 11/2015 changes]

    Wanting to presently being very efficient and effective with, and someday tutorialize how to use, the various tools within just six data recovery programs [or utilities], set up 3 1GB test partitions [NTFS].
    After setting up the 3 test partitions, after full-formatting same, copied the test folders from my d-partition onto said test partitions -- each 1GB partition having two folders with selected files, 1 normal folder in which the files themselves have been deleted, 1 folder of which I simply deleted. The selected files have various extensions such as: mp3, mp4, zip, htm, doc, txt, etc. I named the two folders Undeleted Folder and Deleted Folder.
    From the beginning I'm used Acronis Disk Director to create the test partitions, I used Windows 7 Professional 64 bit NTFS to create the test folders and for copying the already-existing files into said folders. Essentially, W7Pro is the Windows being used by the six DPs. If there are any read/write engines built into the high-end DPs, I'll try to mention them as I use them.
    I changed one partition into DeletedPartition and added one more into the soup: FormattedPartition.
    I "converted" the contents in all partitions into: 1DeletedFiles [folder], 2Deleted Folder, 3DeletedFilesAndFolder,
    -- to represent the most common problems that lead to either a folder/file restore from a previous backup or onward to data recovery [ranging from Whew! GotEmBack! all the way to HoleyMoley100Steps!].
    I simply had to choose what programs and utilities to use, out of so many great choices!, I settled on:
    Piriform Recova, Wise Data Recovery, MiniTool Power Data Recovery, Restorer Ultimate, Steller and R-Studio.

    A quick review of some things. Long ago, us old timers heard of and used terms such as FAT [File Allocation Tables] and DIRectories which were stored right after Boot Sector on Track Zero. FAT and DIR are part of the main post office to the houses, i.e. the folders and files on the magnetic media. I'm not concerned with CDs and DVDs at this time.
    Using an anology that can be snapped like a rubber band if stretched too far: You and your family are the contents within your house, a specific file. The post office knows your street address number and your family name. When a file is simply deleted, the main post office no longer has your [beginning] house number nor the first letter of your family name. If the whole block [a folder] is deleted, although the main post office probably no longer has the stuff mentioned earlier, however, if you're lucky, a sub-station just might have the needed numbers and first letters [along with the whole names] for that block [folder]. Any over-written file, regardless of how or with what the file was over-written with: the people in the house are removed, and often the house itself is in shambles to some degree.
    At this time, I cannot visualize how NTFS is structured, and how it keeps the first address and the name of folders and files. Maybe my use of DMDE will help me discover and visualize this process. I used DMDE's Disk Editor to attempt to locate my FAT16 test partition's Track Zero and its FAT and DIR structure -- didn't recognize it. Using Windows 7 Pro to create, format, write folders & files onto a FAT16 partition probably not the same as using Windows for Workgroup 3.11?

    FAT16 partition, Piriform Recover appeared to give a very easy to work with, understandable, screen of recoverable files within Undeleted Folder. Had to head for home, later, will check and see if all or only half of the files were listed. Wise Data Recovery, while the recovery menu was very easy to work with, it was a little bit "muddy:" half the recoverable files had their correct names, the other half of the recoverable files had manufactered names.
    For the beginner, Piriform Recova seems easier to use, has much less geek-assigned file-names, whether FAT16, FAT32 or NTFS. Wise was much friendlier in my NTFS partition. Piriform Recova did not enter in adv-mode for me today [I had to task-break it]; maybe will try again later.

    MiniTool and Restorer, in FAT16 partition, operate much like Piriform Recova, very few files are missing their first character, most have full names listed. I suspect the same will be true for FAT32. Both, in the NTFS partition, listed only a few files. Not sure why yet. Will find out later in deeper tests.
    Steller and R-Studio early-bird menu items revealed the same listing as the aforementioned others for FAT16, and I suspect will do so for FAT32. Steller's Preview works really well. R-Studio's Preview often coughs up the View and Edit mode rather than the Preview. Both of these, within the NTFS partition, only listed a few files. Again, not sure why, maybe can find out later in deeper tests.
    ** Unless somebody want them, I will not be listing the keystrokes, buttons, etc. to click, push, etc. at this point. **

    Hitting an unexpected snag in my backup via cloning operations on my two computers containing a 2nd internal HD, realizing the project is just too big to handle; and realizing it's time to make things easier to focus via "rifling" rather than "shotgunning"
    -- cut down on the number of test files to 14; only 14 files will go into each of the four test folders in each of the three test partitions
    -- earlier eliminated the FAT16 and FAT32 test partitions [thus only three remain; NTFS, Formatted & Deleted]
    -- eliminated FormattedFolder, since that old ZeroOutFAT&DIR utility no longer is used, may no longer exist
    -- have reCreated but not yet "acted upon" the FormattedPartition and DeletedPartition
    [Now, the cloning works just fine; reworded the beginning to reflect only 3 NTFS partitions exist.]

    My present and future focus will be on: learning to become proficient with my designated six data recovery programs, from EZ-recovery all the way, eventually, before the 2ndComing, to Green Beret level cluster-by-cluster, sector-by-sector, byte-by-byte recoveries.
    I've been using Windows 7 Professional [64-bit] as the OS. All my partitions, OS [C], data [D], test partitions: NTFS 4KB/default.

    what are you starting some kind of Recovery business?? ha..

    got a good story for you..

    Had a 4 TERABYTE! yes 4 Terabyte external USB drive that I accidentally started to format.. it had all my stuff on it!! I quickly pulled the plug out ..

    it was too late! It was now Raw... and all my file allocation tables and MBR or whatever was gone...

    I started down the road of all recovery programs.. I think the best one I liked that actually found my stuff was On-Track or Easus.. can't even remember now which one was better.. I probably can find out for you if interested..

    Then I started trying to use Testdisk.. and while it found 1000's of files.. sometimes it would hang.. and also i need to mention it took 2 weeks to find files on a 4-terabyte hard drive.. I literally left my computer on all day and night just finding files..

    if i had a power outtage.. (which i think i did!) i had to start over! haha.. it may have been 1 week actually ..

    I went back to using ON-Track or Easuse.. which seemed better..

    I will tell you at the time what didn't work - was Recuva!!! how about them apples..

    anyway, I finally got my files back but then the dreaded "file not supported" or "file can't be played" or "codec not recognized" or even the movie and song files not showing everything because!! I didn't defrag my hard drive at all! and everything was all over the place.. so when I went to recover files, if it was a big file, it was spread out and apparently lost.. couldn't put it back together..

    so that's my story about a 4 terabyte recovery..

    i have a few things.. but I think i lost so much...
    and by the way, in this process I bought a 5 - terabyte seagate hard drive just to try to recover the files from the 4-terabyte because all the programs told me I needed a bigger size hard drive to what I was recovering from!!

    I recently had a 1.5TB internal drive suddenly not mount and show up as RAW in Disk Management.

    The tool I used for data recovery was Active@File Recovery Pro -- the best one I've seen in recent times. It works great, but is really S..L..O..W -- taking about 1 hour per GB of data. So, I spent the better part of two weeks recovering files, but every file I recovered was OK.

    Then, I read about HDD regenerator -- which supposedly repaired bad sectors (don't get me started about how software can't fix hardware, I already KNOW that), but it was able to migrate data from 8 bad sectors at the beginning of the drive to 8 other sectors. After that, I was able to remount the drive OK and able to then easily recovery the large files I had avoided due to the time required.

    So, if you run across the RAW problem, you might give that a try. There is a trial version but it's hard to find on the site. The commercial version costs $100, but it's worth the cost if you have a lot of data you want to recover and the data recovery tools are taking forever.

    hddguru has a couple of posters that warn against using over-the-counter, average-to-intermediate user-based, data recovery tools that utilize HD's mark bad sector/move data to another sector feature -- because too often the data in the bad sector [which is now forever out of average person's reach] is "replaced" with something else in the replacement sector. And, the often-forced try-to-read, try-to-read, try-to-read, does the failing HD no good. hddguru forum's Conventional Hard-drives and Lounge has the above information explained much more thoroughly than I could ever explain it.

    Thank you for sharing your experience. About data recovery software I've just used EaseUS that brooksndun had mentioned, and it's free. I have not used any paid version of data recovery software . It is free to restore the 2G file, and enough for me. Because I have the habit of automatically backup files. Most data recovery software cannot successful fully restore all the lost data and if the data is overwritten, it cannot recover the data also . But after listening to your sharing, I also want to try other data recovery software.

    I think the ONtrack program was the best for me though.. but that's just what I remember..

    shoot.. it may have remu recovery.. as they look similar.. haha dog nabbit..

    but for the future there should be no recovering anyway.. save pictures movies etc.. onto 2 external drives.. or whatever stuff you really care about..
