R help - Mar 2005 - difficulties with the save.image() function

Dear list,

I've had difficulty saving my workspace to an .RData file.
This causes considerable frustration as it means that I have to regenerate
my analysis every time I want to update it.  For microarray data in
particular, this can be quite time consuming.

I'm saving my data to a network folder on my system in Windows XP, something
like an "H:\" drive or a "P:\" drive instead of a
"C:\" drive.

Here is the command which saves my workspace to my working directory:
save.image("H:/Consulting/cmlExprA.RData")
And here is the error I get:
Error in save(list = ls(envir = .GlobalEnv, all.names = TRUE), file outfile,:
error writing to connection

Any assistance?

Many thanks,

- Do you have write access?
- Is there enough space available?
- Any quota?
- Can you save on a local drive, say a temp directory?
- How big is the file size? ("microarray" make me assume it is huge,
so
is it > 2GB?, does the system support the file size?)

- What is the output of
  file.info("H:/Consulting/cmlExprA.RData")
and
  file.info("H:/Consulting")
