What is the deal with the specificity of the HDD this rig will accept
So I just had my CPU card fixed, and installed it, along with another HDD. The one it came with was a Seagate ST31000528AS 9SL154-040 .
I know that there is discussion about compatibility of HDDs in this machine, but do not fully understand it.
After some reading up I concluded that it came down to the temp sensor connector being very specific on the A1311. Since I could not find the exact same Seagate, I tried a fully operational Hitachi Deskstar 7K100 1TB 7200 rpm Internal SATA 3.5 Hard Drive HDS721010KLA330, which I still had in my box of parts.
I dealt with the temp sensor by shorting it, to prevent it from spinning full tilt, and then installed Mac fan control and set the HDD to 2500rpm.
I fresh install of OS 10.6.8 on the new drive and all was well.
Next day, for reason beyond my comprehension, it suddenly does not recognize the HDD!! WTF?
My question is : What makes the EMC2308 so HDD fussy? Is there some firmware interfering with my choice of HDD?
Any light on the issue would be, as usual, eternally appreciated....Cheers, J
Esta é uma boa pergunta?
