mac hangs at boot .. unmounted HDD?

[calcalcal]

hey folks

 

the other day i was mucking around on my macbook (10.5, 2 gigs of ram, 2.4)

and i realised that in finder/pathfinder that my one and only harddrive's

eject button was missing... i dont konw wat caused this as my mac has been

continually been on for a few days.. (using sleep instead of shutdown)

but after noticing this i tried to install a few dmgs : "no mountable file systems"

 

so i tried to reboot and but it just hangs on the grey screen with the initial spinning wheel... im quite new to mac so i dont konw how to boot up with the disc and do stuff like that..

 

but i did read on another thread to boot with ctrl S and then type in /sbin/fsck -fy

it said the hdd was ok .. i just think i need to mount it again??????

 

or is that just crazy talk ???

 

any help would be much appreciated

 

oh and also, when the os was working all good i did try "disk utility" , it said that the hdd was/is fine .. but when i selected it and tried to click on mount i couldnt.. it was greyed out!

Try these commands at boot, and maybe you can use tech tool pro 4 if you can’t fix your prob, the other day I fixed a macbook pro with tech tool

 

Command-S Boot into Single User Mode

Command-V Boot using "Verbose" mode (shows all kernel and startup console messages)

X Reset startup disk selection and boot into Mac OS X Server

Shift Boot into "Safe Boot" mode, which runs Disk First Aid. A reboot will be required afterward.

Option Boot into Open Firmware to select a boot device

Command-Option-Shift-Delete Bypass internal harddrive on boot

T Boot into Firewire target disk mode

C Boot from the internal optical drive

N Start from the Network (NetBoot)

it sucks how target disk mode doesnt work mac-pc!

 

i just did an "archive and install" from the leopard disk.. really awesom

 

and it kept all my files!!!!
