Dynamic drive overlay in DOS cause dataloss when upgrading


My current harddisk is a Quantum Fireball on 1040 MB (at least a bit over 1
GB). In order to be able to acces the whole harddisk capacity without
partitioning it i have installed Quantum Dynamic drive overlay V7.01 from
Ontrack Computer Systems. It is AFIK installed somewhere in the FAT
partition. It is at least activated before DOS when starting up, and is not
represented in the autoexec.bat or config.sys.
I did not installed the 32 disk access option in Quantum Dynamic drive
overlay. I had some problem but i can not remember what they were
anymore. This just means that i can't use 32 bit diskacccss in WIN95.
All in all i wolud like to get rid of Quantum Dynamic drive overlay in the
process of upgrading.


My question is what happens when i install WIN95?

Shall i uninstall Quantum Dynamic drive overlay before installation of
WIN95, thereby loosing data.

Can i wait to uninstall Quantum Dynamic drive overlay to after i have
installed WIN95?
     Will i loose data in this way?
     Will i be able to use 32 bit disk access afterwards.

Any other possible advice regarding Quantum Dynamic drive overlay and
upgrading to WIN95 will be most appreciated.

First off, did you install the Dynamic Drive Overlay because you bois would not support a drive over 540MB?  If so, then you will still need to keep it to run Windows 95.  If not, then you didn't need to install it in the first place and it is actually slowing down the machine.

If you installed the drive overlay to have access to the entire hard disk it would have been better to use the "fdisk" utility.

Of course that's all in the past.

To "safely" get rid of the drive overlay, the installation program will need to have a "uninstall" option.  The program is actually located in the first boot sector of the disk and can't be accessed by mortal means.  If it doesn't have an "uninstall" Ontrack's Disk Manager may be able to remove it (about $120).  But, I would format it if, and only if, you are sure you didn't need to install the drive overlay software in the first place.
