    This is exactly the problem.  Wipe Free Space DOES wipe the MFT when this option is unchecked in Options/Settings.


    I think you may be confusing the two processes, which are entirely separate. Unchecking the Wipe MFT box in Options/Settings only applies when you run Wipe Free Space from Cleaner/Windows/Advanced. Using Drive Wiper will wipe the MFT whatever is in the Options/Settings box.

    If you don't want the MFT to be wiped then use WFS from Cleaner/Windows/Advanced.

  2. All you can do is try a larger drive. Are you trying to recover system files, some of which are sparse files with a nominal size of the disk?

    Usually with an SSD it is impossible to recover any file after a format, as that runs a universal TRIM. If Recuva is listing files than perhaps TRIM isn't working across the USB connection. Try a recovery and see what you get.

    Oh yes, you can restore the folder structure (as much as you can) by going into Advanced Mode, selecting Options/Actions, and checking Restore Folder Structure.

  3. Ahh, I missed the bit about it being an SSD. Your chances of recovering file data from and SSD are close to zero.

    Cancel stage 2 as soon as stage 1 ends.

    Forget the $I file, the $R holds the data.

    Whatever you've found look at the header data in the Info pane in Advanced mode.It's likley to be all zeroes. It is almost impossible to recover data from a modern SSD.

  4. Well I don't know everything. Consider that 6.6 gb is only 0.0066 of a terabyte, so it could just be rounding (e.g 1.814 less 0.006 = 1.808 rounded to 1.81).

    Using properties on the drive will give a more accurate figure.

  5. Possibly because drives are specified in terabytes (1k = 1,000 bytes) and Explorer uses tebibytes where 1k = 1024 bytes. So your 2tb disk says 2 terabytes on the label and 1.8 tebibytes when examined by Explorer. It's actually 10 to the power of 12.

    You will have some relatively small system files on there after formatting, but who knows what your 'some files' means.

  6. I guess there's a message under the pics.

    The first pic quite simply says that none of the files found matches the search criterion. No file having that (what looks like a) folder name was found.

    Running a deep scan as seemingly recommended is futile, as files found with a deep scan have no file or folder names associated with them, as they are held in the MFT and a deep scan does not look at the MFT so cannot use anything in the search box.

    If the search criterion is correct then unfortunately there's nothing to be found.

  7. I don't think that that information is held in the MFT record. There is a file created and file modified date field, and a MFT modified date field, but I don't know if the latter is updated on file deletion. Whether or not Recuva doesn't show it.

  8. I don't think that Windows allows FAT32 partitions greater than 32 gb, how large was the partition on the 1 tb disk? How did you get Recuva to recognise the remaining part of the disk? Recuva requires a drive letter to function.

    But the crux is that without a file system Recuva won't be able to do anything. Don't let that stop you trying the various options, scan for non-deleted files etc. You might be lucky, and it's something to do on Christmas Day when the TV is rubbish.

  9. Recuva will list all the deleted file records in the Master File Table. If they're not listed then they're most likely not there. Deleted file records are reused generally in the lowest-numbered record found order, which is why files created and deleted on the same day are likely to be the first to have their MFT records overwritten.

    Nobody knows what user and system activity is going on on your pc.

    If the file names aren't in the MFT then they won't be found elsewhere.

    Unless your packet capture files are in some common format (doc etc) then a deep scan won't find them, and is pointless.

    I don't use the recycler, so I can't answer your question.

  10. I've only had experience with relatively small drives, 500 gb and under, and a deep scan takes about 45 mins at the most. Some people do experience very long scan times, and yours seems exceptionally long. I have no idea what the cause is, or what Recuva is trying to do.

    I usually cancel at stage two and I have never found any detrimental effect, the files found are still displayed. You may wish to try that.

    I also have Truecrypt containers and they do not slow processing down. To Recuva they are files with a name and a cluster allocation, just like any other file. There is no indication to anyone that they are encrypted.

    USB access will probably slow things down a little, but a month is ridiculous.

  11. Files sent to the recycler are renamed to $Irandom.ext and $Rrandom.ext. The $R files are the data, the $I files hold the file name etc.

    As you have created and deleted the files on the same day it is very likely that the MFT records have been overwritten by later activity, as they are reused on a first available record basis.

    Deep scan looks for a specific set of file headers. You describe the files as packet captures: I don't know what they are but unless they fit into the list scanned by Recuva (look at the drop-dpwn list in the File/Path box) themn a deep scan will not find them.

  12. You won't find any folders as Recuva does not recover folders explicitly. Deleted directories contain names of files that don't necessarily exist, and index array offsets that are clearly invalid.

    I don't know why you can't find any files, I can't either. A scan of my disk reveals about 20 files from the documents folder, none of any use. Perhaps Win 10 behaves differntly from its predecessors.

  13. That's the fundamental difference between CC's secure delete and Recuva's. CC can legitimately rename a file because it is still live, but Recuva can't because the file is deleted and its MFT record is inaccessible. Also small files, under 700 bytes or so, can be contained wholly within the MFT so remain in their entirety.

    What is wanted is an independent MFT wiper, with random lower case file names instead of those ugly ZZZ capitals. You can of course build your own MFT wiper. Create a folder on a flash drive with sub-folders holding say 20 files with random names and a few bytes of data. Duplicate the sub-folders until you have a few thousand files. Just copy the lot to your drive, and  then delete them. If you do that all your incriminating file names and contents will have gone.

    Surprisingly since I went to Win 10 I can find hardly any user files with Recuva. It's as if constant updates are overwriting the deleted user data files. Perhaps they are.
