Removable SCSI Media Not Visible in Windows Explorer
ID: Q139712

The information in this article applies to:
SYMPTOMS
When you start Windows 95 on a computer with a SCSI adapter and two
removable-media devices on the SCSI chain, the removable-media devices may
have no drive letter in My Computer or Windows Explorer.
Or, if you start Windows 95 without a disk in the last drive on the SCSI
chain, neither drive letter is available in My Computer or Windows
Explorer.
CAUSE
The Windows 95 protected-mode SCSI drivers do not map a drive letter for
an INT13h removable SCSI drive if the removable media is not present.
Windows 95 can map a drive letter for a removable-media drive on a SCSI
chain if the following conditions are true:
- There is a real-mode ASPI or CAM driver that can be used to allocate
the drive letter.
- There are no drive letters available in real mode that cannot be
accessed correctly for any reason.
RESOLUTION
The following four workarounds are listed in order of preference. These
workarounds allow you to access removable media in Windows 95:
- Assign a permanent drive letter to each removable drive. To do so,
follow these steps:
- In Control Panel, double-click the System icon.
- On the Device Manager tab, double-click the SCSI device, click
the SCSI adapter, and then click Properties.
- On the Settings tab, set the Reserved Drive Letter parameters.
- Click OK. When you are prompted to restart your computer, do so.
- Place the removable media in the drive before you start Windows 95
and do not remove it until Windows 95 starts.
- Load the real-mode ASPI drivers included with the SCSI adapter in the
Config.sys and Autoexec.bat files. For information about how to do
so, please consult the adapter's documentation or manufacturer.
- Turn off the BIOS on the SCSI adapter. For information about how to do
so, please consult the adapter's documentation or manufacturer.
MORE INFORMATION
The Windows 95 protected-mode SCSI adapter drivers always enumerate the
devices through the SCSI chain. Therefore, all devices on the SCSI chain
are child devices of the SCSI adapter. All drives and devices on the SCSI
chain need to be working correctly and have full protected-mode support
through Windows 95 before they can be visible in the user interface.
