Just as an FYI, USB flash drives (a.k.a. thumb drives, pen drives. etc.) do something similar but it's called wear-leveling instead of TRIM. In flash drives, though, it's all automatic (built into the hardware/firmware of the drive) and you never see it or interact with it directly. The flash drive periodically does a "clean-up" process in the background where it moves data around to different places. The very first flash drives didn't have this and tended to wear out pretty quickly, but later flash drives all have it and last a lot longer than the old ones did.
The reason for this is that even though things are solid state, there is still some "wearing" or "degradation" that goes on over time. It supposedly only happens when you write to the disk but not when you read from it. So, at least in theory, you can read an unlimited number of times but if you keep writing to the same places all the time things will eventually wear out and stop working. _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
