Microsoft's New 'Windows File Recovery' Tool Restores Deleted Data (betanews.com) 59
"Anyone familiar with how Windows and other operating systems work might know that files aren't actually deleted, they're marked to allow other data to overwrite them in the future," points out Hot Hardware, noting it's now led to the "quiet" launch of a new free Microsoft tool.
Slashdot reader Mark Wilson writes that the tool even recovers files from drives that were formatted or became corrupt: The command line tool can be used to retrieve data from local hard drives as well as removable media such as USB drives and memory cards...

I just assume the OP is overly paranoid and 0/1 overwrites all deleted files so that no one can ever "undelete" his/her "sensitive" data.
P.S. I doubt that they actually do that for all files deleted but rather was just trying to be snarky.

The sad part is ever since the advent of journaling filesystems, there hasn't really been a good way to wipe just one file in place in the filesystem, because bits and blobs might be kept in a journal somewhere. You're better off wiping a whole FS, or deleting the file and wiping all of the free space on the FS.

"Restores Deleted Data " if you can restore deleted data in my world it was never deleted. At least by someone doing it right. Just my 2 cents ;)
Forcing a write on every sector for some files is overkill, especially on media that might have a more limited number of writes per sector. Marking the space as available/removing the inode is efficient with time and other resources. Want to securely delete something? There are programs for that. Want to free up the space for a new file but don't have the time to wipe the old data? There's sdelete, from Microsoft, which can wipe the free space in the background after you've written the new files. I'd

Perhaps more relevantly, and more predictably anyhow nowadays: Restorable until the OS-issued TRIM command is processed by your SSD.
In normal usage, you won't be able to recover much from an SSD. Small; sub-block size files: sure; and if you're really lucky files deleted while your drive was swamped and you pulled the plug quick enough.
Re: (Score:2)
You confuse me. While it makes sense what you say about TRIM, is it actually true?
For TRIM to work the SSD doesn't have to re-write the block. It just needs to mark the block as 'free'.
What the SSD does with those free blocks and how it reports them might differ. An SSD could choose to let the OS read existing yet deleted data, mimicking HD behaviour, or the SSD could have the block show up as 'empty' since it's marked as unused, like you suggest. The data may still be there, optionally retrievable by low-l

Well there's two problems here, the first one physical, the second with how data is organised on an SSD:
1) The point of the TRIM command was to mark a page as free on an SSD. The reason this was relevant is because an SSD needs to erase an entire block before writing to it, the TRIM command lets the SSD controller know there's no need to erase a page as the data on it is stale and not needed. For a HDD this means that when *new* data is written to a disk there's a chance the deleted data may be lost. For an

I tried this on a crucial SSD, and it returns zero's instantly(from my human perspective) after deletion.
There's good reason to assume all ssd's will do this eagerly, namely that it costs time to do so, and that having more pages free makes wear levelling more effective. For those that don't know; ssd's cannot rewrite data; they can merely clear whole blocks of NAND (iirc typically around 1MB), and then write individual pages (iirc typically 4k).

Yes. But MS tries to do that as late as possible. On Linux ext2/3/4, for example, a freed block has a high probability to be used very soon.

Useful tool, but not magic (Score:2)
The Microsoft support site [microsoft.com] says, "If you want to increase your chances of recovering a file, minimize or avoid using your computer. In the Windows file system, the space used by a deleted file is marked as free space, which means the file data can still exist and be recovered. But any use of your computer can create files, which may over-write this free space at any time."
So, as expected, the tool only recovers bits that have been disassociated from the file system but which have not yet been overwritten.

Your suggestion of overwriting the file would only work on physical spinning drives. With wear-leveling on flash based devices, overwriting a file does not guarantee your original data has actually been erased either. The only way to reliably wipe files on all kinds of storage devices, is to keep your files or the entire drive encrypted, then destroy the keys when you don't need the content anymore.
