Hmmm, never had that problem.
Do you have more Adapters at Home?
That can/could help, because they can be quiet different.
I had 3 back then and one of them only worked when plugged in afterwards (no crash tho)
The one from Trancent was Flawless .. that was PCMCI > Compact Flash.
and another no name brand was PCMCIA > micro SD - that worked also flawless.
The last one had a similar issue like you described, but with no crash.
(cant remember the brand; it has been such a long time)
The point is... if you dont mind; try more Adpaters. Those are quiet cheap and some work better than others.
Also; please don´t go over the 4 GB limit. That leads to problems.
(files can not be seen anymore or become faulty and so on ...)
I only used the PCMCIA for transfering files from my Windose PC to the Amiga, and it was perfect for that
Hope it all works out for you.
Greetz & good luck Supadupa
PS: I also uploaded the Compact Flash Device and Fat 95 ;just in case... put those on your WB and see if this change things.
