  1. I have no experience of this, but typing 'a device that does not exist was specified' into Google may provide the answer.
  2. It doesn't. Ignored files are non-deleted, zero length, and system files, which you would not usually want to 'recover'. It is an unusually low number of files though. Deleted file recovery on an SSD is not normally possible, due to the SSD controller zeroising file data on deletion.

    Ignored files

    Ignored files includes non-deleted files, zero length, system and any files excluded by any selection criteria. In any event I believe formatting an SSD issues a global RETRIM command so the chances of retrieving any valid data are slim.
  4. That's right, it's beyond any recovery software's reach. It's a feature of Windows, NTFS, TRIM, DZAT and the SSD controller, where a file deletion triggers a TRIM command for each page, and following that the SSD controller executes a DZAT (Deterministic Zero After TRIM) response to any read request for that page. Recovery, if possible at all, is generally out of reach of any of the run of the mill authorities.
  5. That's correct. Data clusters are zeroed almost immediately under Windows NTFS.
  6. Was the deleted file also on the D drive? If so there is virtually no chance of recovering the original data, as recovering deleted files from an SSD returns zeroes. In Recuva Advanced Mode look at the header information. If it's all zeroes then the data has gone. A 'perfect' file - I assume you mean in Excellent State - means that the deleted file's clusters have not been overwritten by another live file. Recuva will recover (i.e. copy) what's in those clusters, it cannot tell whether the contents are valid or not.
  7. Recuva does not delete any files during the recovery process, which usually involves recovering files which have already been deleted. However you can 'recover'' live files if you wish, and these will not be deleted. Recuvas does have the capability to overwrite deleted files, but you have to specifically ask it to do so. It will not overwrite live files whatever you do.
  8. Recuva does not 'undelete', whatever that means, but copies everything it finds to a separate device. So a recovery would take at least as long as just copying back the files. Just make sure your copy-from files are secure. I know little about exfat so can't help with what Recuva found.
  9. TRIM commands are issued at the time of file deletion, and are pretty much instantaneous, so it's really too late to stop or reverse anything. TRIM commands however are asynchronous and go to a low-priority queue, and if there's a lot of other activity on the device some commands may be dropped. The regular ReTRIM run by the Storage Optmizer is to mop up any dropped TRIM commands. It runs at a granularity such that no ReTRIM command will be dropped. I've never noticed personally any TRIM commands being dropped, but I've never looked for any. In the end the general rule is there's next to no chance of recovering a deleted file on an SSD.
  10. Like everything, there are exceptions to the rule. TRIM is a Windows feature TRIM is only enabled on NTFS file systems, not FAT or exFAT etc Old versions of Windows don't support TRIM Older SSDs may not support TRIM SSDs may have TRIM disabled (rare) TRIM may be disabled in NTFS (rare) TRIM may not be actioned across USB ports Some small files (under 700 bytes) may be held entirely in the MFT and can be recovered So whilst the vast majority of modernish Windows systems with SSDs will use NTFS and have TRIM enabled (and recovery is therefore extremely unlikely), a few will slip through the net.
  11. It's an SSD. I assume the txt files are small so are held completely within the MFT and are thus recoverable. The other files will have an entry in the MFT which despite being flagged as deleted will contain the addresses of the data clusters, or pages, on the SSD. However pages on an SSD are TRIMed on deletion, so what you are recovering is data full of zeroes. There is no possibility of recovering these files. Assuming a Windows pc/laptop of course.
  12. 1) Not really, if used sparingly on a HDD. A wipe is an overwrite, so it's an n gb write process. 2) It's just a file with a randomish name that's full of zeroes and is used to overwrite the free space on the drive. 3) No, but it wouldn't improve anything either. Just select one pass and don't do it on an SSD. It's not something that you would do regularly, I've never run it on my pc.
  13. Fragmentation on an SSD happens exactly the same as it does on an HDD. Fragmentation is a file with its data spread across multiple and separate groups of clusters, or pages, and it's the file system that determines that. It happens in the same way whether the storage device is an HDD or an SSD, although the consequences may be different.
  14. Wear levelling is entirely within the SSD and under the control of the aptly named SSD controller. If you can see what's in the Flash Translation Layer you're probably in a research lab. If a defragger looked at a disk, looking only at allocated clusters as defined in the cluster bit map, it would just see endless clusters of meaningless data. Where does a file start, and end, and are those thousand clusters in a row all one file, or file fragments, or what? There's no way to know. So defraggers look at the MFT (ignoring FAT for the moment). On;y there is the connection between file and data clusters, and only there are file fragments defined and located.
  15. I have to beg to differ with parts of this.... the third line actually... the first half... Wear levelling is not seen by the operating system, NTFS, or any defragging software. NTFS, or FAT, allocates a cluster number to a file which remains unchanged for the life of the file, unless some user/client action (such as a defrag) occurs. Defraggers get their fragmentation information from the MFT, not from the disk, i.e. how many datarun entries there are in the MFT record for a file. What physical pages on an SSD are actually allocated is anyone's guess.
  16. To everything that John said, I would ask why do you need to recover this folder? Is there a chance that you would revert to a previous version? Windows old is huge (10 gb+) and probably contains many tens, if not hundreds, of thousands of files. Any attempt to recover it is the definition of optimistic.
  17. Because it uses the contents of this file to overwrite the unallocated clusters on your storage device, which is what a drive wipe does.
  18. Do not search with Documents as a filter, as txt files are not classed as such. Do a full scan, switch to Advanced Mode, and enter .txt in the File/Path box. As your device appears to be an SSD then although the file names may be found no data will be recovered, as the SSD zeroes file data on deletion. No software can overcome that.
  19. 'I downloaded Recuva and ran a deep scan'. On what? Presumably your pc? Have the photos gone from your phone? (I have no knowledge of phone support.) Recuva looks for deleted files. Why would your recovered files be deleted? If you're scanning your pc's drive(s) then you may find a lot of files, not just the files you recovered. The files you list look more like temp internet files or something similar than pics. Some are too small to hold anything significant. The names are not produced by a deep scan, as this uses ascending numeral names. ' I selected the ones I wanted to recover'. Why did you select these files? What criteria? Why do you think they are your photos? These are a lot of questions (there are more) but you need to analyse what's going on.
  20. If you are recovering a lot of files with no identifiable folder then they will all go into one default directory. The max directory size in FAT32 is 65536 entries, and one file will require a minimum of two entries. This may be the cause of your problem. Furthermore FAT directory entries are not held in sequence, so for each file added the entire directory has to be scanned to avoid duplicates, which takes time. FAT is probably not the best choice for large recoveries. Is recovering from a 2 tb drive onto a 250gb drive a little optimistic?

    Deleted rar file

    Can you restore the file from the recycle bin? Yes, I believe that NTFS zeroes the cluster addresses when deleting files greater than 4 gb. I have no idea why but NTFS is not designed to recover deleted files. You could try a deep scan in a desperate hope that the file is in one extent and Recuva will recover it, but the odds against that are pretty long. Apart from that the file is unrecoverable, although a professional data recovery company may be able to help.
  22. The answer to your question is right click on the scan results pane and select Save List to Text File, However the rest of your post is confusing. Presumably the SSD is larger than 16gb? Why did you lose files on the HDD when the SSD stopped responding? Did you use cut and paste instead of copy and paste? Where are you recovering your files to if you have to do them in batches?
  23. Please stop posting mutiple copies of this topic. I have removed your ability to post for 24 hrs to enable you to cool down and me to mop up.
  24. I think that the idea that you could recover Win 7 system files and then somehow use them to upgrade your system is disingenuous, to be polite. Even if the files could be recovered (how many are there, 10K+?) then they don't make an install package, and how are you going to reconcile the registry and volume boot record, to name but two, the operating system loader and who knows what else? Doesn't the cd burner work on XP? Or just type win 7 install iso into google. It's available free of charge. Or buy licence for around £5.
  25. Your future posts will be moderated, not because of the content but due to the above being posted half a dozen times in other subforums. I expect that one of Piriform's staff will respond to this. I see you are now posting obscenities. Either respond in a calmer way in this subforum and wait for a response in UK business hours or your ability to post will be removed.
