ARAID 1500 and 2000 Operations Overview
ARAID 1500 General <IMPORTANT>
IDE Drives: Set both IDE hard disks in upper and lower trays to “Master” or “Single Drive” mode allowing the ARAID to detect and recognize the hard disks in the trays.
NOTE: “Cable Select” is the default jumper setting for most new IDE hard disks. You must change the jumper to “Master” mode, or otherwise ARAID won’t detect it.
ARAID 1500 and ARAID 2000 General
Default Mode: ARAID 1500/2000 default operation is UDMA. If it cannot work with the host SATA on your PC in this mode, it will automatically switch to PIO mode 4 or a lower drive speed.
Cooling: ARAID 1500/2000 is equipped with a 70mm cooling fan providing adequate ventilation for hard disk operation at 10,000 rpm. Please check and remove any obstructions in the computer system that may be blocking air to and from the ARAID disk array.
Drive Selection: ARAID works with all drives. We recommend using two new matching drives but two identical drives will work. ARAID is designed with a strict EIDE command set and accurate to work on any operating system without the need of a device driver or RAID I/O controller board.

ARAID 1500 and ARAID 2000 RAID 0 Users
Mode Selection: When ARAID works at RAID 0 mode, the front panel operation mode switch must be always set to Default.
Additional Notes for RAID 0 Users

zAlways place the switch in the “Default” position for RAID 0 operation.
zNever place the switch in the “Single” position or switch it from “Single” to “Default”, or you will risk losing all RAID 0 data.
