I have a Sparc Ultra10 creator 3D. It works with the original hard drive and CD-ROM drive. I upgraded with original Solaris 8 install package without problems. I am trying to replace the Sun OEM 9 GByte hard drive with a 160 GByte Maxtor 6Y160P0. I get the: Bad magic number in disk label Can't open disk label package when I start up. Using probe-IDE I get: Device 0 ( Primary Master ) ATA Model: Maxtor 6Y160P0 Device 1 ( Primary Slave ) Not Present Device 2 ( Secondary Master ) Removable ATAPI Model: CRD-8322B Device 3 ( Secondary Slave ) Not Present The system seems to recognize the drive, but I do not know how to get it to allow me to format so I can use it to boot from. Any help would be appreciated. P.S. The system came with 3 additional PCI graphics adapters (Tech-Source Raptor GFX) I am giving them away to the first three who ask. You pay shipping.
