Hi, thank you for the info.

I use YAMAHA's drive which is one of SGI-friendly drives.
I want to check sequentially in order to avoid confusion;

1) Check with a new SCSI2 cable,
2) If it still makes the error, buy the new CD-ROM drive,
3) Check with the new Drive (standalone)

Anyway, now Dollar/Yen is about to reach 140Y/$, Yahoo! Japan's Auction Site is reasonable for persons who are on out-of-Japan sites, indeed.
Although now SGI machines are not available at the site (no registered), peripherals are there.
