Late 2009 27inch iMac HDD & SSD upgrade

hi all,

decided upgrade hdd in imac 1tb 2tb hdd rapidly running out of space , along way learn't couple of valuable lessons hope useful thinking of doing same.

without reading bought seagate barracuda xt , took imac bits , cut finger (these things razors) thinking replace hdd have done on old white core 2 duo imac. anyway noticed cable attached wd jumper block wouldn't fit on segate drive

turns out if going replace hdd in late 2009 imac need upgrade same drive (albeit higher capacity) installed use propriety cable takes temperature readings drive in turn controls hdd fan , if ain't connected hdd fans spin @ full speed (which noisy)

bought 2tb re4 wd , took imac apart again (cutting different finger time) , attached cable in same position old 1 took off , put imac again. dismay hdd fans started spin full speed again, , knew had put cable on right way round

started have read around , came across imac hdd fan control allows set max , min fan speed of hdd , if wasn't expensive @ £19.99 have bought it, installed , never thought anymore of it......

anyway little reading around , trying find cheaper solution found apple place firmware on hdd (i assume stop people replacing hdd) had resigned self fact had either fork out , buy software or short pins out on cable , use free software control max level of hdd.

found out firmware reverse 2 pins 3rd time opened imac (cut finger 3rd time... getting use ) , reversed cable.... 3rd lucky

know info here within forum , it's own fault not researching enough if sees , reads planning on upgrading hdd in late 2009 imac may of use

fingers have healed i'm thinking of taking out optical drive , putting in ssd , wondered whats best drive bay caddy use 1 see $50 bit steep...

 

wow, lucky enough have imac wd hdd (seagates got recalled). if you, i'd leave hdd it, , have bought external.
