![]() This won't get rid ofthe file names, but as I don't know where they're coming from I can't really suggest anything else. To get rid of them use Recuva's overwrite. ![]() This might be your case as the file sizes are relatively small. I have found a problem with WFS, in that in a drive that has a lot of fragmented free space (although the live files themselves may not be fragmented) some of the smaller space allocations are missed. The screenshot in post 4 is confusing, as file and folder names are only held in the MFT, unless Recuva is digging them up from somewhere I am unaware of. there are no deleted records in the MFT.Ģ) There is something in the file/path filter box in Recuva, and nothing corresponding to this filter is found.ģ) The option in Recuva to show securely deleted files is unchecked, and somehow Recuva can identify those ZZ files as securely deleted (maybe a specific file header?). If you don't see any results with a normal scan, then:ġ) So many new files have been allocated that the MFT is full and is now creating new records for new file allocations, i.e. That's what you see with a normal scan (and also with a deep scan, as a normal scan is run first). It's very likely that there will be some 'deleted' records in the MFT, whether ZZ's or other names. After that, complete data of the hard drive will appear on the screen, choose the required data to wipe free space on a hard drive. Now select Free Space from the Wipe options and then select the drive according to your needs and Next. Drive Wiper runs a wipe MFT before the wipe free space, so you should have seen a Wiping MFT message first. Logical Drives: Select the drive from the machine. The pic in post 1 shows entries in the MFT after they have been wiped, that is after enough 712-byte files have been allocated to overwrite all the free records in the MFT, and then deleted. So be warned.Everything's a partition in Windows, so don't worrry about that. And that being said, a small town police force does not have these kind of resources, so you are probably safe from any casual examination that they would do.Ĥ.) As far as Google searches, every search ever done by anyone is stored somewhere on one of their servers. That being said, entities like the FBI and NSA have very sophisticated techniques of recovering data, even after it has been overwritten. Then it goes back and fills each of these sectors with zeroes, effectively returning these sectors to what appears to be an unused condition. In simple terms, it looks for all the sectors on the drive where the flag is down, and creates it's own file table of where they are located on the drive. This is where a drive wiping utility comes in. Also, defragmenting your drive can overwrite quite a few of these sectors as well, the thing is, you cannot be sure which sectors containing old data were overwritten and which were was not. So keep this in mind, when you delete a file in Windows, it does not completely disappear until all the sectors used to store it get overwritten by a new file. ![]() If the flag is down, it is available for a new write operation, and then one of two things happen: either the old data that was previously stored there gets overwritten by new data, or a previously empty sector gets written to for the first time. When the flag is up, it is in use, and cannot be used to write new data. Think of each sector as a mailbox with a flag on it. All you are doing is changing a file table that the operating system uses to keep track of where the individual pieces of data are stored on the drive, and these little storage units are called sectors. This is because when you delete a file in Windows, the data still physically remains on the drive. It can exist in one of two conditions: either it was previously written to and used to store data, or it was never used and contains no data. I'll try to answer your four questions a simply as I can.ġ.) As long as you deleted your browser history prior to doing a drive wipe, it's gone.Ģ.) As long as you deleted any other files prior to doing a drive wipe, they are gone.ģ.) A bit more tricky - Free space refers to all the space that can be used to perform new write operations to your drive. It's very difficult to describe how a hard drive works without getting technical, and I certainly make no claim to knowing anything more than the basics.
