I'm no expert, but checking the R-help list, I got the impression that
saving a workspace often leads to problems.
The interesting question (for me) would be to know why and how the
corrupted file got corrupted, and then, what to do to avoid the problem
if one really wants to save the workspace.
For you Bazman76, I would advise you to never save the workspace. Save
all command lines in a script (*.R) and important objects to files
(either with save() and then load(), or one of the write functions, or
saveObject()/loadObject from package R.utils, and so on).
Someone please correct me if it is a bad practice.
That is good advice.
One way to end up with a "corrupted" workspace is to save it with a
dependency on a particular package, then try to load it when that
package is unavailable. I'm going to see if R can handle that case more
gracefully.
If people can describe other reproducible methods of getting a corrupted
.Rdata it would be useful, at least for a list of "Don't do that" advice.

I will read the intor to R.
When closing I got a pop up asking me if I wanted to save the workspace I
just clicked yes?
here is what I got
load("C:/Documents and Settings/Hugh/My Documents/vars/vars/data")
Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection
In addition: Warning message:
In readChar(con, 5L, useBytes = TRUE) :
