[QUOTE="mike23, post: 919307, member: 123771"] [b]Many Thanks[/b] Many many thanks for the two helpful replies so far. My machine has been in storage for over 2 and a half years ! After resetting all internal connections resetting PRAM, changing battery etc etc, I tried booting the machine via diagnostic CDs with the HDD connected with results as follows : [B]HDD CONNECTED TO LOGIC BOARD[/B] SOFTWARE INSTALL & RESTORE CD – Apple Logo and clock spinner appears but spinner keeps moving around without doing anything further. APPLE HARDWARE TEST CD – booted to loading screen which stuck at the words loading and no further. MAC OS X X CODE TOOLS – nothing showing except grey screen. HOWEVER …. [B]HDD DISCONNECTED TO LOGIC BOARD[/B] Although the HDD seems to be working ? it's making a ticking/clicking sound ? I finally got the machine to boot from the APPLE HARDWARE TEST CD having first disconnected the HDD from the logic board. I ran the extended test and everything passed OK. I also booted up using the SOFTWARE INSTALL AND RESTORE CD again without the HDD connected and I got to the normal OS software install menu sequence. I obviously could not reload the OS because the HDD was disconnected. I have reset the HDD IDE connection ie to both the HDD itself and the logic board and the PSU to the HDD. CONSEQUENTLY I THINK THAT THE HDD IS AT FAULT. [COLOR="Red"][B]MAC SK - How can I get the HDD to become "unstuck" ?[/B][/COLOR] Got any further opinions/tips please ? Many thanks. Mike :) [/QUOTE]
