ADAPTEC EZ-SCSI UTILITY Troubleshooting Tips SCSI Device Troubleshooting Review this checklist if your newly-installed SCSI disk drives, CDROM drives, and other devices do not seem to work properly: • Be sure that termination is correctly set for all devices on the SCSI bus, as • • • • described in your host adapter documentation. Be sure there are no hardware conflicts such as devices in your computer trying to use the same interrupts (IRQs) or DMA channels.
IX. ADAPTEC EZ-SCSI UTILITY If the name of your SCSI chipset does not appear, you may be able to find its miniport driver on the Windows95 CD-ROM. Follow these steps: 1 Place the Windows95 CD-ROM in your CDROM drive and run the Add New Hardware wizard. 2 Select No on the second screen, and select SCSI controllers on the next screen. 3 Click on the Have Disk button, then click the Browse button. 4 Look in the \drivers\storage directory of the CDROM and select the name of your SCSI host adapter if it appears.
IX. ADAPTEC EZ-SCSI UTILITY If I am running under Windows95, do I need lines for the Adaptec real mode ASPI drivers and mscdex in my CONFIG.SYS and AUTOEXEC.BAT files? Usually, you do not need to use these real mode ASPI drivers, because the new Windows miniport drivers support most SCSI host adapters and SCSI devices.
IX. ADAPTEC EZ-SCSI UTILITY Information for DOS/Windows 3.1x Users The following information may be useful if you install Adaptec EZSCSI on a computer running DOS, Windows 3.1x, or Windows for Workgroups3.1x.

IX. ADAPTEC EZ-SCSI UTILITY DOS Formatting Utilities Adaptec EZSCSI includes several DOS-based formatting utilities: Low-level Formatter (scsifmt) Use the DOS-based scsifmt utility for low-level formatting of SCSI hard disk drives, removable media, Floptical® drives, and magneto-optical drives. You can also use it to scan a disk device for surface defects before you store data on it. Run scsifmt from the DOS prompt, not from the Windows MSDOS prompt.
IX. ADAPTEC EZ-SCSI UTILITY Formatter and Partitioner (afdisk) Use the DOS-based afdisk utility to partition and format SCSI hard disk drives, Floptical drives, and magneto-optical drives. You can also use afdisk to remove DOS and non-DOS partitions from a disk drive and to format removable media in standard hard disk format, OS/2 floppy format, or DOS V (Japanese) format.
