[Freedos-user] SHSURDRV Write Protection Violation

[Lester <fd...@op...>]

I'm trying to replace SRDISK with SHSURDRV (v1.11, 2005-12-21) to make a 
ram drive "E". Fdconfig and Fdauto load ok but when using Arachne 
browser, after exiting (to dos shell or permanently), I get the following 
error:

"error reading from drive E: DOS area: write protection violation 
attempted"

Readme file mentions /W switch but it's supposed to be used only with 
shsufdrv and not shsurdrv. I didn't try it because it looks like a high 
risk experiment (host drive corruption can occur).

"/W images are writable (SHSUFDRV)

By default images are not writable, due to problems  I  had  in  getting 
write to actually work. If you'd like to give it a go, use this option, 
but be warned: image and "host" (the drive the image is  on)  corruption 
may occur.	To test it, use SHSURDRV to make a RAM drive, copy the image 
to that, then use SHSUFDRV on the copy.  If you still want	some  images 
to be read-only, make the file itself read-only."
