TRIM tool for DOS!

Hi, son of R.Loew was so kind to let us share his tools. He even posted some source codes for the TRIM tool that I asked him for.
https://msfn.org/board/topic/180215-rloew-1952-2019-has-passed-away/page/4
Please have a look at code, can you guess what compiler he used? Could Borland C work? I'll try it but maybe he used some other 16-bit compiler. I wonder how many code is in inline assembly, very few standard C functions used, probably only printf. The source doesn't contain any #include statement, thats quite weird...

My goal is to be able to rebuild the code and extend support to FAT16. I also hope it will help me to finish my own TRIM tool that I started to code but nobody could help me with DMA IDE command where I had stucked...

Well, the code looks a bit cryptic but it compiles with BC++ 4.52, just to ignore tons of warnings about missing prototypes. This can be fixed easily creating a header file...

I'm happy that you got it to compile.

Looking forward to following your progress on this. It will be wonderful to have a TRIM utility for pure DOS. SSDs truly will be useable in DOS systems at that point.

You can try to use existing version if you have FAT32 partition. I didn't tested it yet as I don't have spare SSD for testing and I don't wan to risk data loss on my system SSD that is quite full...

R.Loew passed away.

This is sad news indeed. As far as i can tell, he had little presence here, but was a highly-knowledgeable, helpful, and frequent contributor to the MSFN forum's Windows 9x pages (which of course, includes DOS).

Among the useful DOS programs and drivers he had developed are: AHCI CD driver, Terabyte hard-disk driver, MS-DOS v8.0 IO.SYS de-compressor, advanced FDisk and Format, TRIM for SSDs, XFile (CLI file-management utility, very useful in batch files), and others.

Fortunately, his web site is now being re-maintained by his family, and over time, his software (now freeware, including source code) is being re-uploaded:

My thanks to his family for keeping his fine work available, and now available to all.
