LOL, probably not. Download the "ultimate boot CD" and see if any of its tools under the hdd section can find anything.

47 is correct. Even if you scan the drive sector-by-sector, the OS install wrote to large parts of the disk, and the sectors that it wrote to, being overwritten with new data, cannot be recovered. There may be data lurking in currently-unused sectors, but your odds of recovering your files are not much better than winning the lottery.

If you format a hard drive, it effectively erases all data on the drive. Back-up and/or copy any important files to a separate medium (burn to disk, copy to another drive, etc...) before format and reinstall.

Doesn't your format utility clearly specify in bold red letters that formatting a hard drive will cause all data to be erased, and that subsequently overwriting the formatted drive will cause permanent, unrecoverable data loss? Didn't it occur to you that you should perhaps backup your files before formatting?

Anyhow, there may be hope - typically the OS sets itself in the first available sectors of the drive (it doesn't just choose a location at random), hence if you installed only the OS after formatting, there may be hope of recovering your data, or at least some of it. First try and download some file recovery software (on a different hard drive, don't be stupid), and if that doesn't work then you can either give up or submit your hard drive to forensics, which should recover your data (again, maybe not all of it) with good probability but will also cost a lot of money.

Nope, they are lost.
Next time think before you format ;)

No, quick formating alone will not permanently erase all data.
Installing an OS over top of a quick formated drive however will unfortunately overwright much of the drive making recovery unlikely.

Maybe you should read the post again, a little slower this time.

After formating he installed an OS on the drive.
This effectively overwrights much of the drive making data recovery unlikely ;)

Not really... as I said in my post, if the drive already had an OS installed (which it has since the OP mentioned he installed a "new" OS), then the new OS will overwrite the old one (because they all place themselves in the first HDD clusters), and perhaps a little bit of data if the new OS is larger than the old one. But he definitely didn't permanently lose all his data - he likely lost some, but not all of it.

Last time seeing as no one seems to be able to read....

What process exactly did you go through when you installed your OS, are you sure sure you formatted, can you check C:\ for a folder called windows.old just in case you think you formatted and did not format!

Format recovery is possible on formatted hard disk or memory card.

It also works on twice formatted disk.

Tips: You should stop using your disk or your system. Stop checking disk when Windows start up or do some other things.

Do not change your disk file system before doing the recovery.

If your data were not stored on c drive, then it is okay that your data can be restored.

First, DO NOT USE THE DRIVE, and DO NOT FORMAT IT. When you delete files, you are only removing the indexes to them (not actually deleting them). However, they are at risk of being overwritten. I would try running Recuva on it (might need a deep scan). Also, recover the files to another drive - this is CRITICAL to avoiding overwriting the drive.

Finally, next time, remember to keep a backup. (FYI, there is in fact a 4GB file size limit on FAT32 drives. exFAT is intended for thumb drives more than NTFS and will do the trick while being fully compatible with Macs, but requires some updates to work - you should already have these.)
