DOS DISK/FAT32 TRIM Package (Demo) TRIMCHK Test Program Version 1.1 06/03/2015 Copyright (C) 2015 By Rudolph R. Loew The DOS DISK/FAT32 TRIM Program allows the user to send TRIM Commands to SSD Drives so that the Drives Controller can reuse data blocks that are no longer needed. The TRIMCHK Program allows the user to determine if a given Drive can be Trimmed by the TRIM Program without performing an actual TRIM. It is the Demo Package for the TRIM program so you can test compatability before purchasing the Full TRIM Package. REQUIREMENTS: Bootable DOS OS. SSD or other Drive that supports TRIM Command. Hard Disk Controller BIOS that reports Control Ports via INT 13 AH=48 USB or Firewire Connected Drives are NOT supported. Only FAT32 Filesystem supported for selective TRIM. PURPOSE: Operating systems older than Windows 7 do not provide TRIM functionality so SSD Drives accumulate no longer used data blocks that it doesn't know can be reused. This can greatly slow Write operations to the Drive. DRIVES AND PARTITIONS: The TRIMCHK Program accepts INT 13 Disk Numbers starting at 0x80 or Drive Letters starting with C:. Specifying Disk Numbers tells TRIMCHK to test a specific Physical Drive. Disk Numbers start at 0x80 or 128. TRIMCHK allows either representation. Specifying Drive Letters tells TRIMCHK to identify the Drive holding a particular Partition and run the compatability test on it. SYNTAX: The syntax for the TRIMCHK Program is: TRIMCHK Drive|Disk Drive is the Drive Letter of a Partition to test. or Disk is the INT 13 Number of the Disk to test. First Hard Disk is 0x80 or 128. WINDOWS: The TRIMCHK Program cannot be run from Windows, even in a DOS Box. It must be run from Real Mode DOS.
