within 1 file cluster) and are reported as "No overwritten clusters are detected" 64 bit Recuva v1.42.544 under Windows 7 Ultimate + SP1 with Trim active has found 30821 files in C:\ on my 60 GB OCZ Vertex 2 SSD.Īlmost none of them are more than 1 kB (i.e. Is my pessimism justified, or is RECUVA more clever than I thought ? I also suspect that some SSD products may possibly choose to refrain from reading back from any NAND cells that are subject to a pending TRIM. I further expect that Windows and therefore Recuva will be kept totally ignorant of when TRIM has occurred,Īnd therefore Recuva will not know when or if a relevant page of NAND cells has been erased.Ī further complication is that even if a file used consecutive LBA file clusters the SSD might write them to different pages of NAND cells,Īnd a "staggered" TRIM might result in some sections of data being erased before others. Probably immediately upon deletion before Windows forgets what it has to do My expectation is that on a TRIM capable system, Windows will issue TRIM after a file is deleted, My expectation is that there is little difference in capability with either so long as TRIM has not occurred.
