1. The probability of recovering data after a full reformat is very slim, because the data is most likely overwritten.

2. Yes and no. After deleting something from the recycling bin, that's considered permanently deleting a file off of your computer. However, any technician or a person with decent knowledge can easily recover that file. Some programs allow you to "permanently" delete a file by making it unrecoverable, however, I've never used one and I don't know how reliable or safe they are.

3. You can recover deleted data from a hard drive using any decent data recovery program. There are really no good "free" ones. If you do a search on here there's a lot of threads asking, I'm sure you can find any information you need in those threads.

4. Depends on what passwords you're speaking of. Windows stores user account passwords in what is known as the Security Accounts Manager, or SAM. Passwords are stored as a hash and since NT4 have been protected by SYSKEY. Passwords that you type into websites on a browser are encrypted as well.

If you set Firefox to always remember your password for several sites then the information will be stored (encrypted with the master password if you've set one, and you should have) in the signons2.txt and key3.db files in your Firefox profile folder. If you ticked the "remember me" checkbox on some websites then your login information for that website are stored in the cookies.

1. If you did a format through just Windows whatever was not overwritten has a decent chance of being recovered. If a full format with zeroing the chances are slim. Only difference between defaults of quick and full in Windows is full scans disk surface.
2. You can use a program that overwrites the file repeatedly with 0/1/Random achieving "permanent" deletion. Plenty of programs out there. Eraser is a good one. It's usually termed wiping a file.
3. Again a whole multitude of programs that can scan your hard drive for basic recovery. Recuva is a popular one though not the most effective. Seems like you have one already.
4. Of course there are. Depends if you save them in the first place. Good security practice is to never save a password unless necessary. It's unavoidable for OS login among other things and although it's encrypted like anything not impossible to get at. Good practice says to change it often on a cycle with a strong password.

Is it a deleted partition?

Format is nothing. The index.dat file which points to the files locations gets deleted and a new gets written. That's all.
Now you can sit for hours and search every sector and recover the data or you can do the obvious. Recover the index.dat that was deleted and you will have your deleted partition back the way it was.

Get get data back ntfs and partition table dr 3. All you do is let get data back run for a min or 2 then stop it. Look right in the beginning you should see the deleted index.dat file. Then recover it to a external drive or flash drive or any other place except for on the drive your trying to recover. Then run partition table dr. It has a option to save and load the index file. Now first back up the current index.dat file. Rename it to index2.dat when you save it so you don't overwrite your recovered one. Then all you do is choose the replace index.dat on disk option. It will write that index file to the disk where it will point to all those files you have lost locations. It shouldn't take you more than 5 min to recover the deleted partition doesn't matter what size drive it is

If you want a easy to use solution to recover deleted files, there is a program called Recuva that will scan your system and allow you to restore previously "Permanently Deleted" files.
