SUMMARY
=======
After performing standard troubleshooting for a damaged DoubleSpace compressed
volume file (CVF), it may be possible to recover some or all of the information
by running CHKDSK /F.
MORE INFORMATION
================
Depending on the severity of the damage, running CHKDSK /F on the affected drive
may create .CHK extension files that may be mountable. However, if DBLSPACE.00n
is still present, it is likely that the .CHK files are not part of the original
CVF. If it is determined that extremely large .CHK file(s) do exist on the
affected drive and DBLSPACE.00n is no longer present, do the following:
1. Rename the .CHK file(s) to DBLSPACE.00n. To do this, type the following at
the MS-DOS command prompt and then press ENTER:
" ren c:\file000n.chk c:\dblspace.000 " (without the quotation marks)
2. Insert MS-DOS 6.0 Disk 3 (3.5-inch) or Disk 4 (5.25-inch), and type the
following at the MS-DOS command prompt, and then press ENTER:
" expand a:dblspace.ex_ c:\dblspace.exe " (without the quotation marks)
3. Remove all floppy disks, reboot, then type the following at the MS-DOS
command prompt and press ENTER:
" c:\dblspace /mo=00n " (without the quotation marks)
NOTE: Alternatively, you can run DBLSPACE.EXE, choose Mount from the Drive menu,
and try to mount C:\DBLSPACE.00n.
