  1. Well, this is heresy, but here goes: Remove the multiple pass overwrite option on secure file deletion and Drive Wiper, leaving one zero-byte pass only, saving decades of lost time and tons of CO2 in wasted energy. Surprisingly for a tech and science dominated field, the multipass myth has achieved unquestionable god-like status. It was thoroughly debunked over twenty years ago. Chances of being adopted - close to zero.
  2. The Ignored Files includes live files, zero-byte files, system files etc, which you would not normally want to recover. Also if there is any file name or path in the aptly named Filename or Path box then this will restrict the results, possibly down to zero. The free and paid version have the same recovery facilities.
  3. If by 'Exited the list' you mean closed the program, yes, you will have to do a rerun. If you mean that you have, for example, typed a search word in the File/Path box, then clearing that should restore the original list. Scan results are held in memory to avoid overwriting data, so when the program closes the results are gone. If your storage device is an SSD then post back here first.
  4. Google it, and you will know as much as I do.
  5. How should I know? I doubt if it was supported years ago as 64k+ clusters were only introduced in NTFS in late 2017. Why not try Windows defragger?
  6. This seems to indicate that not much supports clusters over 64k, at the time it was written. It seems a pretty serious change. https://dfir.ru/2019/04/23/ntfs-large-clusters/ And the About Defraggler page states that defragging NTFS clusters greater than 64k isn't supported. https://support.piriform.com/hc/en-us/articles/360048065892-What-Defraggler-can-and-can-t-do
  7. Good to hear that copies come to the rescue. As for disabling TRIM, that advice sounds as if you disable TRIM after discovering that files have been accidentally deleted. This would be ineffective as TRIM is an asynchronous command issued on file deletion and disabling it afterwards is shutting the stable door when the nag has well and truly galloped off down the road. For this method to work you'd have to have TRIM disabled permanently, which is possible if not recommended (although I'm not fully convinced of it's worth these days).
  8. It's (probably) due to the way the SSD controller handles deletes, NAND flash architecture, and Windows TRIM for a start. When a page is deleted TRIM notifies the controller and the controller unmaps the page. Any reads of that page, as Recuva will do when if follows the cluster run addresses held in the MFT, will return a default page, commonly of zeroes or less commonly random data. Look up DZAT and DRAT on Google. In the real world deleted data on an SSD has gone forever. The unmapped page is in limbo, and is wiped, sooner or later, by the SSD Garbage Collection process. Perhaps, just
  9. If the drive is an SSD then you're unlikely to recover any valid data, although what you do recover should contain zeroes not a hex char. If the O/S is FAT32 then the file cluster addresses are modified on deletion, so that they point to a different, and incorrect, cluster. Recovery is again unlikely.
  10. Yes, it all depends on what the OP means. In my experience if Recuva can list a file then it can - in general - recover it. Exceptions (that I can think of) are if the file is zero bytes in length, or the cluster addresses are invalid, or it's a live file that's locked for some reason. In each case there should be an error message. If the recovery is from an SSD then the files can be recovered, but will contain zeroes, which might be what the OP means.
  11. Of course the MFT was recreated during the format, that's what a format does. The MFT should contain about 20 or so system files and nothing else. A deep scan will not return any directory information, as this is held in the MFT. You would be better off running a normal scan with Scan for Non-Deleted Files checked. This is fast and, if successful, will return much of what you want.
  12. It's certainly going to make recovery difficult. Did you check Scan for Non-Deleted Files? If so these files - with file names and directory info - will be worthless, as the cluster addresses are multiples of block sizes, the wrong block size. You need to look at the deep scan files, those with just a number and extension. Assuming the sector alignment is the same (i.e. both block sizes start at the same boundary) then you may possibly find and recover some files. But you will be retrieving two 16k blocks in one 32k read. Whether this is valid, and for all file types, I don't know. Also y
  13. I don't think that a deep scan will be fruitful as the file extension - unity - is not, as far as I know - one that is interpreted by a deep scan. Data not found on disk means that the file's data cluster address fields do not contain valid addresses. It is not easy to say why this has happened. It may be because the files were in a lot of extents.
  14. You could also try Explorer, right click drive, select Disk Cleanup, Cleanup System Files. Windows Update Cleanup will be first on the list, and if you check that and run Cleanup you should save several gbs.
  15. If Recuva shows a list of deleted files that's OK, these are the entries in the Master File Table flagged as deleted. They can't be removed, but will be reused by Windows as and when new files are allocated. The important thing is can you see the deleted data (which will be mostly pics)? If so then TRIM isn't enabled. With an SSD you should not be able to see the data, just zeroes. But as I said this won't affect the free/used space. Regarding your large files, do you have System Restore switched on? (CC will tell you if you have or not.) The default for Win 10 is off, so that may remove
  16. TRIM is a process which is enabled by default in both the Op Sys and the SSD itself. It doesn't actually affect the disk space parameters, as that is (probably, possibly?) deduced from the cluster bitmap, and will be the same whether TRIM is enabled or not. Something must be using your space so try Hazlenut's suggestions. I assume you are right clicking the drive in Explorer and selecting Properties to get the space usage figures?
  17. Difficult to say really. I would disconnect from the internet to see if that stabilises things. A CC Analyze will tell you what temp files can be deleted, and if these temp files are huge then before you delete then look at which component holds the huge files, Then post back here. We are assuming that TRIM is enabled in both the Op Sys and the device? An easy way to check is to run Recuva normal scan on the SSD. If you can see lots of pics and data etc on the deleted files then TRIM is off. If the vast majority of the deleted files are blank/zeroes, then TRIM is on.
  18. Recuva recovers the right contents, but not necessarily in the right order (perhaps you need to be old, and English, for that one). You've been around for too long for me to give you a lecture Willy, but this is too good an opportunity to miss. Recuva looks at, and displays, the meta data from the MFT during a normal scan. When Recuva recovers a file it follows the data cluster addresses in the MFT and copies whatever is there faithfully. There is no way that Recuva can verify that the data matches the file type, or whether it should, or whether it's what you are looking for. Recuva

    Ignored Files

    The ignored files are live files and those which are not selected in Advanced Mode Options/Actions, such as zero byte or system files.
  20. I doubt whether anyone is still discussing upgrading a 15+ year old Dell 5150. Indeed, I have one slowly returning to its elemental form in the shed. In the meantime some of us have graduated, married, raised a family, divorced, forged new careers, retired or died, as well as voting out George W Bush and Tony Blair (but not Mr Putin). And bought new kit. This smells of spam (why do spammers pick such old threads?) so your recommendation has gone the way of the 5150.
  21. I recommend 'Stop Forum Spam'. You have a bit part in it.
  22. Yes, it doesn't look too good. If the file headers aren't there then I doubt if the rest of the file is there either. It's probably due to the formatting with the Win10 upgrade. I don't know how you managed to retrieve the file names, they should have gone with the formatting too. The excellent state just says that no other file is overwriting them, not that the file contains any data that is of any use to the user.
  23. Is the formatted drive an SSD? If so the files are very likely gone forever. How did you find the deleted files after a format? The MFT (assuming NTFS) would have been recreated. Did you select Scan for Non-Deleted Files in Options/Actions? In the Recuva scan (you can run it multiple times with no adverse effects) go into Advanced Mode and look at the file header pane. Is the header all zeroes, or something else?
  24. It's true that in Drive Wiper there is no option for selecting a wipe MFT, but that's because you get it anyway as a freebie. If Drive Wiper WFS is run you will see a Wiping MFT message at the start of the run. It could be argued that a WMFT is part of WFS, as some file data is held in the MFT record and is not wiped by a 'normal' WFS. As far as I know the WFS parameters in Options/Settings have no effect on Drive Wiper. The Wipe Alternate Data Streams and Wipe Cluster Tips are settings for Secure File Deletion, which is not part of Wipe Free Space. I think that the reason why W
