Strange Errors Occur with Resize on DoubleSpace CVF (111739)

• Microsoft MS-DOS operating system 6.0

When you try to resize a DoubleSpace-compressed drive that was created with
MS-DOS 6.0, you may receive one of the following jumbled error messages if
the read-only file attribute is set on your AUTOEXEC.BAT file:
NOTE: These errors can occur whether you try to resize the drive from the
command line or within DoubleSpace Manager.
The following jumbled error message may occur when you install DoubleSpace
if the read-only attribute is set on your AUTOEXEC.BAT file:
This behavior occurs because DoubleSpace must modify the AUTOEXEC.BAT file
so that in the event of a power failure during the resize operation, it can
correctly resume operation at the point at which it failed. DoubleSpace
cannot modify and save the file if AUTOEXEC.BAT is marked as read-only.
Microsoft has confirmed this to be a problem in MS-DOS version 6.0. This
problem was corrected in MS-DOS version 6.2.
To return the computer to its original state and complete the resizing of
the DoubleSpace-compressed drive, copy AUTOEXEC.00<n> to <compressed
drive>:\AUTOEXEC.BAT. Then, check the file attribute of the file by typing
"attrib autoexec.bat" (without the quotation marks) at the MS-DOS command
prompt. If an uppercase letter R is displayed to the left of the
AUTOEXEC.BAT file, the read-only attribute is set and must be removed. To
remove this attribute, type the following at the MS-DOS command prompt
and then try to resize the drive again.
If the CONFIG.SYS file also has its read-only attribute set, you must copy
CONFIG.00<n> to <compressed drive>:\CONFIG.SYS as well.
When you perform a resizing operation, DoubleSpace makes backup copies of
the AUTOEXEC.BAT and CONFIG.SYS files and saves them as AUTOEXEC.00<n> and
CONFIG.00<n> (where <n> is a number between 1 and 9) in the root directory
of the host drive for drive C. For example, if the host drive for your
drive C compressed volume file (CVF) is H, these files are located on the
root directory of drive H, and might have the filenames AUTOEXEC.001 and
After the resizing operation fails, the original files, AUTOEXEC.BAT and
CONFIG.SYS, are deleted from drive C (the CVF).
