- TITLE :You have a SCSI Hard Disk Drive and MemMaker Hangs
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- If you have an SCSI hard disk and MemMaker stops responding (hangs), a
- device driver may be loading into upper memory before the SMARTDrive
- double_buffer driver in the CONFIG.SYS file.
-
- Workaround
- ----------
-
- To work around this problem,
-
- 1. Restart your computer (if you haven't already done so).
-
- 2. When MemMaker prompts you for input, choose Cancel And Undo Changes.
-
- 3. Use MS-DOS Editor to add the following line to the beginning of
- your CONFIG.SYS file:
-
- device=c:\dos\smartdrv.exe /double_buffer
-
- Note: If this line already appears in your CONFIG.SYS file, make
- sure it is the first line.
-
- 4. Save your CONFIG.SYS file.
-
- 5. Try running MemMaker again.
-
- If this does not correct the problem refer to Chapter 6 of the
- "Microsoft MS-DOS 6 User's Guide" for information about
- troubleshooting MemMaker.

- Summary:
-
- To determine the current settings for the following four environment
- variables set in the CONFIG.SYS file, MemMaker scans memory:
-
- Buffers=
- FCBS=
- Files=
- Lastdrive=
-
- MemMaker searches memory instead of reading the CONFIG.SYS file
- because a third-party memory manager may be loading these commands

- --------------------------------------------------------------------
-
- Summary:
-
- When you use DoubleSpace to convert a Stacker volume file (SVF) to a
- DoubleSpace compressed volume, you receive the following error message
- if the Stacker volume file has never been mounted:
-
- Error: DoubleSpace cannot convert your Stacker drives because
- they have a cluster size other than 8K. To convert your Stacker
- drives to DoubleSpace format, follow the instructions in the

-
- Workaround
- ----------
-
- If your Stacker volume file has never been mounted, either mount the
- Stacker volume file and then run DoubleSpace, or mount the Stacker
- volume file, dismount the Stacker volume file, and then run
- DoubleSpace.

-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- If Windows is installed on your computer when you run the MS-DOS 6
- Upgrade Setup program, Setup installs a Tools menu in the File Manager
- toolbar. If you use Norton Desktop for Windows, you have two Tools
- menus after you install the MS-DOS 6 Upgrade.
-
- This problem occurs because Norton Desktop for Windows has one Tools
- menu and inherits a second one from File Manager by reading the
- WINFILE.INI file.
-
- More Information:
-
- The two tools menus have different functions. The Tools menu in File
- Manager and the Tools menu in Norton Desktop for Windows give you the
- following options:
-
- Command Description
- ---------------------------------
-
- Backup Runs Microsoft Backup
- Antivirus Runs Microsoft Anti-Virus
- DoubleSpace Info Provides DoubleSpace statistics if you have
- DoubleSpace installed
-
- You can keep both Tools menus in Norton Desktop for Windows or you can
- remove the second Tools menu by telling Norton Desktop for Windows to
- ignore the add-ins section in the File Manager information file
- (WINFILE.INI).
-
- To configure Norton Desktop for Windows to ignore File Manager
- add-ins, set MaxWinFileExtensions equal to zero in your NDW.INI file.

- TITLE :RAMDRIVE.SYS Should Precede DBLSPACE.SYS in CONFIG.SYS
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- The RAMDRIVE.SYS line in the CONFIG.SYS file should precede the
- DBLSPACE.SYS line or the RAMDrive will receive a different drive
- designation from what it was before. This can become a problem if you
- have many batch files referencing the RAMDrive. For example, if your
- batch files reference drive D and it becomes drive I after DoubleSpace
- is installed, your batch files will not work.
-
- More Information:
-
- The drives used for DoubleSpace are selected from the last available
- drive rather than the first available drive. If RAMDRIVE.SYS precedes
- the DBLSPACE.SYS line, then the RAMDrive's drive letter comes right
- after the last physical drive. For example, if you have a drive C and a
- floppy disk drive A, then the RAMDrive is assigned the letter D.
-
- If the RAMDRIVE.SYS line comes after the DBLSPACE.SYS line,
- DoubleSpace has already allocated all the drive letters between drive
- C and its host drive (probably drive H) so the RAMDrive is assigned
- letter I.
-
- For information on how DoubleSpace assigns host drive letters, query
- on the following words in the Microsoft Knowledge Base:
-
- doublespace and assigns and host
-
- For more information on RAMDrive, type "help ramdrive.sys" (without

-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft MS-DOS operating system version 6.0
- --------------------------------------------------------------------
-
- Summary:
-
- Unlike previous versions of Microsoft MS-DOS, when you install MS-DOS
- 6 Upgrade, the Shell command in the CONFIG.SYS file is not updated if
- you are not using COMMAND.COM.
-
- More Information:
-
- If you are using a third-party shell with MS-DOS 6.0, you may have
- problems with multiple-configuration menus, MemMaker, and the startup
- function keys (F5 and F8).
-
- To correct these problems, either use COMMAND.COM or contact your
- third-party shell manufacturer for an updated version.
-
- The default Shell command for MS-DOS 6 Upgrade is as follows:
-
- shell=c:\dos\command.com c:\dos /p
-
- If the current Shell is COMMAND.COM, Setup updates the path, keeps the

- --------------------------------------------------------------------
-
- Summary:
-
- After you upgrade to MS-DOS 6.0, you may receive the following message
- if you are using Stacker:
-
- WARNING: Unrecognized load high method. Unable to verify driver fit
-
- The driver does load successfully, but you must press a key to
- continue.
-
- More Information:
-
- This message occurs if you use a DEVICEHIGH= command for the Stacker
- device drivers in your CONFIG.SYS file. It does not occur if you use a
- DEVICE= command.
-
- Workaround
- ----------
-
- To work around this problem, ensure the command for SETVER.EXE is
- located above the Stacker device drivers in the CONFIG.SYS file. To do
- this, SETVER.EXE must be located on the uncompressed Stacker
- partition.
-
- 1. Copy SETVER.EXE to the uncompressed drive. For example, if your
- compressed drive is C and the swap drive is D, copy SETVER.EXE to
- drive D as follows:
-
- copy c:\dos\setver.exe d:\
-
- 2. Put the following SETVER.EXE statement at the top of your
- CONFIG.SYS file:

- --------------------------------------------------------------------
-
- Summary:
-
- If you receive the following error message when you attempt to mount a
- compressed volume file (CVF), your CVF is probably too fragmented:
-
- Unrecognized Error #109
-
- To work around this problem, either increase the MaxFileFragments
- setting in the DBLSPACE.INI file or defragment the CVF. These
- procedures are outlined below.
-
- More Information:
-
- To work around this problem, do the following:
-
- 1. Edit the DBLSPACE.INI file and increase the MaxFileFragments
- setting by using the following steps:
-
- Warning: If you use the incorrect drive letters when you edit the
- DBLSPACE.INI file, the system may stop responding (hang) when you
- restart it.
-
- a. Remove the Read-Only, System, and Hidden file attributes on the
- DBLSPACE.INI file. For example, if drive H is your host drive,
- type the following at the MS-DOS command prompt and press ENTER:
-
- attrib h:\dblspace.ini -r -s -h
-
- b. Using MS-DOS Editor, edit the DBLSPACE.INI file and increase the
- value for MaxFileFragments.
-
- c. Save the DBLSPACE.INI file and quit MS-DOS Editor.
-
- d. Use the ATTRIB command to reset the file attributes on
- DBLSPACE.INI. For example, if your host drive is drive H, type the
- following command and press ENTER:
-
- attrib h:\dblspace.ini +r +s +h
-
- 2. Restart your computer and try to mount the drive again. If you
- still cannot mount the CVF, proceed to step 3.
-
- 3. Clear the file attributes from the DoubleSpace CVF and defragment the
- drive using the procedure below.
-
- Warning: If the DoubleSpace CVF is mounted when you perform this
- procedure, you will corrupt your DoubleSpace drive.
-
- a. Unmount your DoubleSpace drive or start your computer from an
- MS-DOS 6 system disk in drive A that does not have a DBLSPACE.BIN
- file.
-
- b. Remove the Read-Only, System, and Hidden file attributes on the
- DBLSPACE.XXX file. For example, if file is H:\DBLSPACE.000, type
- the following at the MS-DOS command prompt and press ENTER:
-
- attrib h:\dblspace.000 -r -s -h
-
- c. Run MS-DOS Defragmenter by typing DEFRAG at the MS-DOS command
- prompt and pressing ENTER.

- The following three subjects are covered:
-
- - Actual Compression Ratio
- - Estimated Compression Ratio
- - Viewing and Changing the Compression Ratio
-

-
- Actual Compression Ratio
- ------------------------
-
- The actual compression ratio (ACR) represents the compression ratio
- for data that already exists on a drive. The ACR varies over time
- depending on the type of files you store on you hard disk.
-
- The ACR is calculated by dividing the sum of the uncompressed data
- size by the physical space consumed after the data is compressed. For
- example, if a disk with 100 megabytes (MB) of uncompressed data is
- compressed and occupies 50 MB of disk space, the compression ratio is
- 2:1. The formula is as follows:
-
- 100MB/50MB =2.0
-
- Note: 2.0 is written as 2.0:1 (that is, 2 to 1)
-
- Estimated Compression Ratio
- ---------------------------
-
- The estimated compression ratio is a number that DoubleSpace uses to
- calculate the amount of free space on a compressed drive. Changing the
- ECR doesn't change the compression algorithm or the ACR. It simply
- changes the value that DoubleSpace uses to estimate the free disk
- space.
-
- You may need to increase the compression ratio if you are trying to
- store several new highly compressible files and you are low on disk
- space.
-
- For more information on ECR:
-
- - Run DoubleSpace, choose Change Ratio from the Drive menu, and then
- press the F1 function key.
-
- -or-
-
- - Type "help dblspace /ratio" (without the quotation marks) at the
- MS-DOS command prompt.
-
- Viewing and Changing the Compression Ratio
- ------------------------------------------
-
- To view the ACR and ECR for a drive, type "dblspace" (without the
- quotation marks) at the MS-DOS command prompt, select the drive you
- are interested in, and then press the ENTER key.
-
- To view the ACR for a file or directory, use the DIR /C or DIR /CH
- command. For example, to see the ACR for COMMAND.COM, type the
- following at the MS-DOS command prompt:
-
- dir c:\command.com /ch
-
- To view the ACR for the DOS directory, type the following at the
- MS-DOS command prompt:
-
- dir \dos /ch
-
- Note: DIR /C reports the ACR of the compressed data based on an
- 8-kilobyte (K) cluster size. DIR /CH reports the ACR based on the
- compressed data based on the host drive cluster size. Use this number
- when you compare the ACR and ECR.
-
- To set the ECR to the ACR value, type "dblspace /ratio" (without the
- quotation marks) at the MS-DOS command prompt.
-
- To set the ECR to a specific value, type the following at the MS-DOS
- command prompt:
-
- dblspace /ratio=n.n
-
- where "n.n" is the ECR value.
