Manually TRIMming SSDs without TRIM - 06-07-2014, 07:25 PM
After having been hit by the Dell Mini 9's OEM STEC drive's flaw resulting in "Operating System Not Found", I installed a Kingspec mPCI-e PATA SSD that's compatible with the Mini 9. I could not get Win8.1's Disk Defragmenter to "optimize" the SSD (it did recognize it as SSD) and the command-line DEFRAG.EXE would give some sort of cryptic hex error whenever I ran "defrag c: /L". This was despite Win8.1's "fsutil behavior query DisableDeleteNotify" returning DisableDeleteNotify = 0.
So, after checking a bunch of forums and running CrystalDiskInfo, I found that the Kingspec drive doesn't support TRIM. But after reading this OCZ forum post, I found that I could manually TRIM by using Win8.1's DEFRAG.EXE to consolidate free space then use FreeSpaceCleaner 1.0 (bottom of the page; needs .NET framework).
So, to manually TRIM, use the following method...
FreeSpaceCleaner will fill up all of your available free space with 1s and will release it when finished, so be aware of that--you probably won't want to use your PC during this time & wouldn't hurt to reboot afterwards. But when completed, you'll have, effectively, TRIMmed your drive...
P.S. XP & Vista include no support for TRIM, but the above method would work for those OSes with a 3rd party defragmenter. Windows 7 only supports TRIM on SATA drives using AHCI, and only for files that are deleted (no free space TRIM). Windows 8.x supports TRIM via more drive interfaces, but I'm finding conflicting info online whether it supports TRIM on PATA drives. (Doesn't matter in my case with the Kingspec, since the firmware doesn't have built-in TRIM).
