Using Logic … If You Delete Something It’s No Longer There …?

1. CanadaRA Says

   When you delete a file, it isn’t that you computer goes to every bit of that file and erases it.
   Instead, the computer’s filing system deletes the reference to the file. The file is still there, but it can’t be seen in normal use because its address has been deleted.
   This is like the phone company cutting off your phone. Your house is still there, but the phone number isn’t in the phone book so nobody can call and everybody thinks you have gone.
   You can still visit the house (see the file) if you use an alternate way to access it – which is what drive recovery programs do. Instead of relying on the file system’s directory of whats on the drive, the programs go and read the drive and try to reconstruct the file’s directory entry from the remaining pieces.
   Now, over time, the hard drive space that the file’s bits actually sit on will be overwritten by other data. Once the file’s data has been overwritten, the chance of recovery falls to near-zero.
   Most formats are “Quick Formats” which don’t actually overwrite the drive (because that would take many minutes or hours to do), which is why data can be recovered from reformatted drive sometimes.
   If you do a secure erase or secure format of a drive, or use a program with a secure erase free space feature, these functions will repeatedly write meaningless 1s and 0s over all the ‘empty’ space of the drive, which eliminates almost all chance of recovery.

   If your deleted files are not overwritten by new data, you can recover them although they are not in the recycle bin. Actually, when you deleted files, they are not deleted permanently, they are still in the hard drive, only unaccessible, you can get them back with the third party data recovery program. Try Card Data Recovery for Windows, it can help you get back deleted files.

   your hard drive is never really empty they all have the certain things that save to it when it comes from a factory programed with so many mega bites thats whats left from whats all ready been put on. Now if your buying a used hard drive and u format it then theres still factory programs on there that cant be removed.

   Deleting or formatting won’t make the data on a computer erase permanently(Even permanently deleted with “Delete + Shift” or emptied recycle bin).Those deleted files are still stored on your PC, they’re just invisible or inaccessible. You can recover them with data recovery software. But once the deleted files were overwritten by new data,they are gone for good.
   I used to recover deleted files from my laptop with Tenorshare Data Recovery.
   Anyway,you can download it and scan your PC for free to preview whether you can recover your deleted files. You can get it from:

   Note: Do not save your recovered files on C: drive and the drive your files located in.
