SSD and file recovery (on Windows 8)

Typical commercial "file recovery tools" are not usefull on modern SSDs, because the recovered file (if any) appears empty.

Windows 8 sends the TRIM command to the SSD when a file gets deleted from trash. Similarly the new "disk optimizer" is supposed to run a TRIM on the drive SSD on monthly schedule (instead of the old defrag on hdd).

My question: is it possible to avoid the instant-TRIM, but keep the monthly-TRIM, so that the "file recovery" works again?

In fact, does turning off [disabledeletenotify]1 fully disable it system wide including both instant+monthly TRIM?

Would this forum post help?

According to that thread, you can disable TRIM by issuing the command:

fsutil behavior set disabledeletenotify 1

And you can re-enable it by this means:

fsutil behavior set disabledeletenotify 0

If you want to query the current status of TRIM:

fsutil behavior query disabledeletenotify

And the results of that query can be explained thusly:

DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
DisableDeleteNotify = 0 (Windows TRIM commands are enabled)

You could create two batch/cmd scripts, one to enable and the other to disable TRIM.

Of course, you could always try some of these solutions.
