SCSI - Small Computer System Interface, pronounced "skuzzy." A high performance alternative to the less expensive ATA/ATAPI Interface found on most of today's Desktop Computer Systems.

SCAM - SCSI Configured AutoMatically. A subset of Plug and Play (PnP) that allows SCSI IDs to be changed by software rather than by flipping switches or changing jumpers. Both the SCSI host adapter and peripheral must support SCAM. According to IBM, "In RAID environments, it is important to disable SCAM. Newer drives have SCAM disabled as default or removed completely." History, See: Plug and Play SCSI (SCAM).

INCITS T10 coordinates closely with the SCSI Trade Association to map standards to industry needs." (4/23/2003)

  7. scsi connector types and pictures




1. Install a 50-pin ribbon connector making sure pin 1, which can be identified by the striped edge of the cable, is closest to the power connector on the drive.

2. Install a DC power cable to the back of the drive.

3. Verify the SCSI ID selection.

·         Note: SCSI ID usually needs to be set to 0 to be the boot drive. The last physical device on the SCSI bus must be terminated. Any other drive or SCSI device connected between the host and the device at the end of the bus must not be terminated.

4. Apply power to the computer.

4a. When memory test is complete go into your system's Standard C-MOS set-up.

·         (Note:  There are various ways to get into C-MOS set-up, please refer to system's manual for instructions.)

4b. Set the drive type to "Not Installed". This intelligent drive will identify itself to the SCSI host adapter.

5. Boot from a DOS diskette that has FDISK.EXE and FORMAT.COM on it. At the A> prompt type in FDISK. At the menu options select option 1 to create a DOS partition. Another menu will appear and from those options choose 1 to create a Primary DOS partition. Select yes to make 1 large partition and it will automatically become active. Then escape from FDISK.

6. At the A> prompt type in FORMAT C:/S   This does a high-level format on the drive and transfers the system files in order for the drive to be bootable.

·         (Note: SCSI drives are low-level formatted at the factory)

7. The drive is now bootable. As a test remove the DOS diskette from A and press reset to re-boot the computer, a C> should be displayed, the drive is now ready for operation.
