PRB: Visual Basic Setup Fails on Disk 2

• Standard, Professional, and Enterprise Editions of Microsoft Visual Basic, 16-bit and 32-bit, for Windows, version 4.0
• Standard and Professional Editions of Microsoft Visual Basic for Windows, version 3.0

SYMPTOMS

In Visual Basic, the Setup program fails after you insert Disk 2.

CAUSE

This does not necessarily mean that the disk is defective. It could be that the physical drive is not reading the disk properly.

RESOLUTION

You may need to use the MS-DOS DRIVPARM command to correct the problem. If a physical drive is not reading a disk properly and the disk is not defective, the MS-DOS DRIVPARM command in the CONFIG.SYS file can often correct the problem. The DRIVPARM command modifies the parameters of an existing physical drive. It does not create a new logical drive. The settings specified in the DRIVPARM command over-ride the driver definitions for any previous block device.

MORE INFORMATION

The DRIVPARM command does not correct any problems reading floppy disks if the disks are defective. In the case of defective disks, it is necessary to obtain replacement disks from Microsoft Technical Support.

Symptoms of Disk Drive Not Reading Properly

Place a Setup disk (Disk 1) in drive A or drive B, and use the MS-DOS DIR command to display a directory list of that disk. Switch to Disk 2, and use the MS-DOS DIR command to display a directory of Disk 2. If you receive another directory list for Disk 1, your logical drive is reading incorrectly.

DRIVPARM Command and Its Parameters

If your logical drive is reading incorrectly, add the following statement to your system's CONFIG.SYS file:

   drivparm=/d:number /f:factor

The /f:factor item specifies the drive type. The factor numbers for drive types are:

   0 = 160K/180K or 320K/360K
   1 = 1.2 megabyte (MB)
   2 = 720K (3.5-inch disk)
   5 = Hard disk
   6 = Tape
   7 = 1.44 MB (3.5-inch disk)
   8 = Read/write optical disk
   9 = 2.88 MB (3.5-inch disk)

Additional Workarounds

Method One:

Eject Disk 2 and press ENTER. Then reinsert the disk and press ENTER again.

Method Two:

When you are prompted to change disks, insert disk 2. Then press ALT+TAB to change the focus to File Manager (or to Program Manager and start File Manager). Select drive A and press F5 to force a refresh. Press ALT+TAB to return the focus to Setup and continue.
