DiskTrim 2.2 by Antoni Sawicki and Tomasz Nowak Requires Windows 2012 R2 / Windows 8.1 or above DiskTrim -- a small command line utility for Windows that allows to send TRIM / UNMAP / DISCARD commands directly to an SSD drive. The operation is performed arbitrarily on a full sector range from zero to the end. It securely erases contents of an entire SSD drive, and tests whether TRIM actually worked. You can also think of it as blkdiscard(8) utility for Windows. If you just want to test if your SSD supports TRIM without deleting it's entire contents, you can simply create and mount a small .VHDX file on top and run DiskTrim on the VHDX instead of physical disk. WARNING: This utility is particularly dangerous and if used incorrectly - it will permanently destroy contents of your SSD drive, and delete all your data. Authors of this software application take absolutely no responsibility for use of this program and its consequences.
