ARTICLE-ID:Q95819
TITLE :Defragmenter Err Msg: 'Insufficient Memory...'
--------------------------------------------------------------------
The information in this article applies to:
- Microsoft MS-DOS operating system version 6.0
--------------------------------------------------------------------
Summary:
If there are too many files and directories on your hard drive, MS-DOS
Defragmenter (DEFRAG) can run out of memory. If Defragmenter runs out
of memory before beginning optimization, you will receive the
following error message:
Insufficient memory - Error Reading the FAT
Defragmenter is limited by the number of files/directories and NOT the
disk size. It is unlikely you will see this problem unless you have
more than 10,000 files/directories on your drive.
You may be able to alleviate the problem by increasing the amount of
free conventional memory and available upper memory blocks (UMBs).
More Information:
If you have freed as much conventional memory as possible and you are
using a 386 or 486 machine, try the following temporary workaround:
1. Make sure EMM386.EXE is being loaded in the CONFIG.SYS file.
2. Using an ASCII text editor such as MS-DOS Edit, add the I=A000-BF77
and NOEM parameters to the device=C:\DOS\EMM386.EXE line in the
CONFIG.SYS.
Note: The A000-B7FF range is commonly used by video cards. Unless
you have a monochrome video card, do not run any graphics
applications when you are using the I=A000-B7FF parameter.
3. Save the CONFIG.SYS file and quit the text editor.
4. Restart your computer.
5. Run Defragmenter with the /G0 switch to prevent it from running in
graphics mode. For example, you would type:
defrag /g0
Note: The switch is G and the number zero not G and the letter O.
6. Edit your CONFIG.SYS file and remove the parameters you added in
step 2.
7. Save the text file, exit the editor and restart your computer.
If, after following the above procedure, you continue to run out of
memory when you attempt to defragment your drive, the problem is most
likely occurring because you have more files than Defragmenter handle.
To optimize your disk, you will need to remove some files from your
disk. If this problem occurs frequently, you may want to consider
creating smaller partitions or multiple DoubleSpace drives on the same
partition.
