Recover files on a SSD?

Hi there, I had a book I was writing on a SSD, and I reformatted it without remembering to back up the file. I tried a quick scan with Recuva and it didn't find anything. I'm wondering if it's possible to recover deleted files on a SSD? Maybe not after a reformat? Thanks.
 
It's just like any other disk, but if you've written new information to the disk the likelihood of being able to recover anything is low.

Actually that is quite incorrect. SSDs are different when it comes to data recovery as they employ a system known as TRIM. It's a system in which the OS logs the LBA's of files that are deleted and reports it back to the SSD. The SSD then begins to wipe (zero out) the now free blocks during the next idle period. This is done to maintain efficiency and speed with SSDs as they need to always zero out a memory page before writing new data to it. So it's getting the memory ready for future writes.

So unless the SSD wasn't properly set up with TRIM, or the files are still in the Recycle Bin or saved within Windows Volume Shadow Copy they are most likely unrecoverable. Sorry to say. Though it depends on how you formatted it, and what OS you used. If you were using an OS disk or other live boot media, it may not have supported TRIM. However you'll want to immediately clone it on a sector level to prevent any future SSD idle activities such as wear leveling that will quickly corrupt the data. Then work from the clone.
 
Partition recovery will work regardless of it being formatted. You can use TestDisk or something like Reclaime to recover partitions and or data really easily.
