You need a properly functioning Master Boot Record (mbr) that properly loads the DDO for the Disk Manager Program to allow the operating system to see the hard drive. Disk manager has done this in various ways during the version revisions. It is also essential to use a proper version of diskmanager that supports Windows 95. It sounds like you have an earlier version. If it is, you "can?" still "save the data" but might need a newer Disk Manager version, also. This is a very "version specific" question. But an easier answer is to get the latest version of disk management software from the hd manufacturer. Some manufacturers oem software even supports the removal or conversion of Disk Manager to another brand. (E-Z drive - MaxBlast comes to mind.) Conversion is recommended "only when absolutely necessary". >My friend would prefer to not use OnTrack, ... even >if it means not accessing the full capacity of the HD. If you said the choice was 504m or 515m, I would agree. To give up 400m out of 800m on a Win95 system is a little extreme. Depending on how you want to proceed, the list might need to know: Your HD manufacturer, your Disk Manager version (on boot screen, and the floppy and do they match), and (optional) was Win95 an upgrade at same time. This is a low level system question with lots of twists and turns.
