Problem with disk space!!!

Hi. I have a problem with disk space. What can I do ??? I use parameters

 2 PARAM(s) were set:
    CHECKEL,NO
    HASHASSM,YES
  

** WARNING # 1971
 Current run is likely to fail due to insufficient disk space.
 Estimated disk space requirement = 222019 MB
 Estimated disk space available = 107723 MB
  Suggestions to reduce disk space requirements:
 For static analysis - reduce the number of loadcases.
 For eigenvalue/buckling analysis - reduce frequency range in
 EIGRL card or number of modes requested.
 For FRF analysis - reduce the number of loading frequencies.
 For transient analysis - reduce the number of output time steps.

 *** ERROR # 158 ***
 Error encountered when accessing the scratch file.
    error from subroutine xdslsv 
    Solver error no. =   -702 
 This may be caused by insufficient disk space or some other
 system resource related limitations.
 Try one or more of the following workarounds if you think otherwise 
 and if this issue happens on Windows. 
 - Resubmit a job. 
 - Avoid writing scratch files in the drive where the Operating System is 
   installed (start the job on other drive or use TMPDIR/-tmpdir options).  
 - Disable real time protection at minimum for files with extension rs~ .
 - Use of environment variable OS_SCRATCH_EXT=txt may help. 
 This error was detected in subroutine statslv.
  
 This error occurs in module 'lstatdrv'.
