Hello MacRumors! I hope this is the right forum. I recently bought a used Macbook 3.1 a couple weeks back. It has a 320GB Western Digital Blue Scorpio HDD, running Snow Leopard (can't remember version). It has worked perfectly until I stupidly forgot that I had completely discharged the battery earlier, and unplugged the charger within like 5-10 minutes of plugging it in. The computer shut off instantly. I smacked myself in the head for being so dumb, then waited at least 20 minutes before connecting it to power again. Now, it does not startup - the boot disk cannot be found. After long periods of blank-ness (over 10 minutes) I have encountered a solid, non-blinking 'question mark folder' once, and a blinking version once as well (when I held 'x' on startup). I have never seen the 'flashing question mark' by itself, with no folder. Otherwise, it only has the blank gray screen. I've never seen the spinning gear or startup icons at this point. The startup chime sounds every time. I have tried many PRAM resets, and I attempted SMC/power mgmt. reset but I think I was doing it incorrectly so I will try again when I can - *EDIT* proper SMC reset did not work. Safe Boot doesn't run, when I hold 'option' to choose a drive there is only a cursor - the hard drive is not detected. Verbose and Single User Mode do not work. The hard drive is also not detected by my eMac when the Macbook is put into Firewire Disk Target mode. Additionally, when I put the eMac into FDT mode, the Macbook saw it but would not let me select it for start up. The computer did not come with any install disks to try and use. It does have a warranty in case my HDD is actually dead, but I am more inclined to think its corrupted/software is damaged. I don't hear any abnormal noises (clicking, grinds, repeated sounds of failed attempts to work, etc.) from the HDD. I've removed it twice to ensure it wasn't jarred out of place by some unknown force (never been dropped). The big problem is that I'm twice-an-idiot - I failed to backup any of my data in time. I kept putting it off. STUPID! Anyone have any advice on how I can possibly fix this? Or else, begin data recovery (either a recommended DIY program or if I should find a pro) or repairs? Many thanks.
