Anyone else got TRIM/the Toolbox working with SATA-I? That would rule out one of my lines of investigation. TRIM appears to be an ATA command and I thought independent of the interface being SATA I vs SATA II, but I stand to be corrected.
My research so far leads me to believe that due to the lack of AHCI drivers on my system, the Toolbox/Optimizer fails to recognise the partition (this is stated as a requirement for the Toolbox, but I understood from a forum posting that IDE mode would be fine).
My guess is that Intel have limited the Toolbox to the AHCI API - great: my laptop has an AHCI capable chipset, however Dell BIOS limitations mean I cannot turn that mode on.
Looks like I made an error when I did not pick an opposition's make of SSD.
