Cannot save STUDY to external hard drive (MATLAB eeglab)

I am having trouble saving my STUDY in EEGLAB to my external hard drive. I had no issues in the past and recently I am unable to save anything to this location. I have set my dr to the specified region and I beleive permissions have been checked and verified. The error I recieve is as follows:

Unable to write file 'xx.study'

This is not a bug (Error occured in function_savestudy() at line 171)

Here is the line of code in bold:

% [filepath filenamenoext ext] = fileparts(varargin{1});

% filename = [filenamenoext '.study']; % make sure a .study extension

STUDY.filepath = g.filepath;

STUDY.filename = g.filename;

STUDYfile = fullfile(STUDY.filepath,STUDY.filename);

STUDYTMP = STUDY;

STUDY = std_rmalldatafields(STUDY);

eeglab_options;

if option_saveversion6, save('-v6' , STUDYfile, 'STUDY');

else save('-v7.3' , STUDYfile, 'STUDY');

end

STUDY = STUDYTMP;

Any help would be greatly appreciated!

Thank you!

I suggest changing the -v6 to -v7

Doesn't seem to work. I keep receiving a "cannot get file position" error.

I have no problem loading a STUDY and when I try to dave on my desktop rather than my ssd I am able to but then encounter a javascript error when precomputing channel measures...

yes，sir，may be save as .mat file，such as

save('-v7.3' , [STUDYfile '.mat'], 'STUDY');

[Luke Pezanko]

No luck. Don't see an option to save as a .mat. Am I to replace the line below 171 with the .mat line? I'm a novice so apologies in advance.
