If you run Symantec's Norton Desktop for Windows or Central Point Software's PC Tools for Windows, your DoubleSpace-compressed Bernoulli drive(s) may unmount when you start Windows or when you choose to refresh the display. Choosing the Bernoulli drive letter in File Manager shows one file called READTHIS.TXT. If opened, the file states:

This disk has been compressed by MS-DOS DBLSPACE.
To make this disks contents accessible change to the
drive and type: DBLSPACE /MOUNT


This problem occurs when you use older Bernoulli drivers.


To work around this problem, update your Bernoulli drivers to version 1.21 or later.

Norton Desktop for Windows, PC Tools for Windows, and Bernoulli drives are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
