i would make sure whatever drive u are using is sata1 + sata2 compatible
i think that was the reason why some users had problem with newer samsung drives??
because they were sata III spec only?
https://kb.sandisk.com/app/answers/detail/a_id/8142/~/difference-between-sata-i%2C-sata-ii-and-sata-iiias far as i understand it.. SATA III can downgrade to be compatible with SATA II, while only SATAII can downgrade to be compatible with SATA I - why is this important? well most of the sata adapters compatible to be bootable with mac os 9 only support SATA I!!!!! so u need a SATA II or SATA I hard drive to connect to it.. maybe some users can post testimonial if they are successfully using SATA III on a SATA150 (sata I) pci adapter.. or perhaps some IDE-SATA adapters have the ability to make this a moot point. (ie that they handle the conversion from SATA to IDE, regardless of speed/spec)
What is the difference between SATA I, SATA II and SATA III?
SATA I (revision 1.x) interface, formally known as SATA 1.5Gb/s, is the first generation SATA interface running at 1.5 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 150MB/s.
SATA II (revision 2.x) interface, formally known as SATA 3Gb/s, is a second generation SATA interface running at 3.0 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 300MB/s.
SATA III (revision 3.x) interface, formally known as SATA 6Gb/s, is a third generation SATA interface running at 6.0Gb/s. The bandwidth throughput, which is supported by the interface, is up to 600MB/s. This interface is backwards compatible with SATA 3 Gb/s interface. (SATAII)
SATA II specifications provide backward compatibility to function on SATA I ports.
SATA III specifications provide backward compatibility to function on SATA I and SATA II ports.
ok! that is reassuring, but im fairly certain this is not the case for *ALL* SATA III drives
(such as that newer samsung drive?)
However, the maximum speed of the drive will be slower due to the lower speed limitations of the port.
Example: SanDisk Extreme SSD, which supports SATA 6Gb/s interface and when connected to SATA 6Gb/s port, can reach up to 550/520MB/s sequential read and sequential write speed rates respectively. However, when the drive is connected to SATA 3 Gb/s port, it can reach up to 285/275MB/s sequential read and sequential write speed rates respectively.
**** due to hd speed being affected by spec/support
this is why i was previously posting about non-bootable sata pci cards, in an effort to see if there were OTHER NON-BOOTABLE PCI sata cards that,
while not being able to boot, may still be USABLE in os9, and offer support for a higher SATA spec (ie: supporting SATA II, providing a speed increase over SATA I
