I did, the main Quantum LPS is set to DS and the Seagate is set to slave. It gives me 1782 error.

Try with the cable select option , also do you respect the connectors order ? end ribbon connector for master/middle connector for slave ?

Be very careful. Big issue is getting two drive working especially for any hard drives that uses *cirrus logic* chip for ATA interface is *broken* in this mode. Is your Seagate has the cirrus logic?

Back in the day we see this all the time. Best solution is get rid of the Seagate and get another one that has no cirrus logic ATA interface chip. And very slow performance.

This means *all* ATA Conner, some Seagate with Cirrus Logic, and very rare few other brands that uses this as well.

Known good: Any WDAC, Seagate, Any Quantum and most Fujitsu, Maxtor, etc.

Sorry about that.

Cheers,

Both of them dont have Cirrus Logic. I gave up on this.

If the Quantum LPS is to be master, but you're getting the disk error when the Seagate is configured as slave, try setting both the DS and SP jumpers on the Quantum drive.
The Seagate drive may not be asserting DASP (Drive Active Slave Present) on Pin 39, creating a conflict with the Quantum drive.

The SP jumper is only used when the second drive in a two drive configuration does not support DASP. DASP (Drive active / drive 1 present) is a CAM (Common Access Method) defined signal that indicates the presence of a second drive, DASP is used during power on initialization and after a reset. Prior to this definition, products were introduced which did not utilize this method to detect the presence of a second drive. The SP jumper is only used on the MASTER drive, with the DS jumper, when the second drive does not support DASP.

Nevermind....I misread 😁
