i gave it another try with a compact flash for my A1200. I formatted as SFS, follow the correct instructions, but could only do it in Miggy, in UAE i was not able to recognize the card, (i have that option in the command line after .exe bla Bla bla). After A1200 did the partition and format, winuae can read it.
After that i went copy all files with Filemaster3 (inside winuae) from my classicwb 3.9 to the CF card. He crashed 2 times during the copy (screen freeze). When i try to copy demos or games (whdload)
he crashes even more. So to copy all files i need a lot of time. But the CF in the miggy works perfectly. benchmark gives much better speed then FFS.
But why the hell he crushes so much in winuae, and works well in miggy? I am using a 8GB CF with 2 partitions with 3.8 GB each.
I try to use only 1 partition with 500mb but it's the same thing. If i use FFS, i does not crash.
I am sure i did the correct steps in hdtools and used smartfilesystem file.

How to use a CF in Winuae? Like a normal external HD?
