I was getting corruption even in that case. If it'd be > useful, I could repeat my testing. There are cases where the in core vnode will be (incorrectly, IMO) marked for update. This occurs even on the FFS. The DOSFS code is not very robust in this regard... I believe the answer may be "yes". What I really need to do is buy another drive from Rod, install Win95 on the thing, and Frisbee it into my developement box so I can pound on a VFAT FS from scratch. I just haven't gotten around to doing this yet -- my own fault. Since I've been doing nothing but building BSD FS code on Win95 for the last 6 months or so, this would be pretty trivial for me to do. > At any rate, I'd be willing to test out any candidate fixes (provided I > have enough time to get a good system backup done :-)). If any of them come from me, expect a total FS rewrite to get them; I'm already pretty torn in the BSD department because the BSD model can't support multiple name spaces very well. I need a flat logical numeric namespace seperate from the inode numbering for internationalization of well known system files in any case. Consider a Samba server that is serving files to Win95 clients and you'll see the problem.
