Doesn't see hard drive

It sounds like you are trying to install Windows 7, if this is the case then put the instalation disk into the drive and run the 'repair' option.
With Windows 7 it should fix the problem automatically.

Hello, presumably you've reinstalled Windows after fitting your new drive. Well, you have to find all the drivers for your machine including the chipset drivers (importantly you must install these 1st)) then your system will 'see' the adapter. If you don't have your driver cd's, then you must go to the web site of Acer (obviously from a machine that can access the internet!) and download all the relevant drivers to a memory stick or burn 'em to a cd, then install them onto your own system.

Check connections. If that doesn't work, try putting it in a different computer. If that doesn't work it's probably broken.

Hard drives are very sensitive, your going to need to replace the hard drive. You might want to hurry and replace it before it doesn't work at all. Your lucky you can still backup your data.

if you want to use another hard drive you have to install a new Windows Operating System

This is not good news. That blinking "?" icon means that the computer is unable to find a disk drive that contains what it needs to start up. It's a real problem, and if you are not an experienced computer person, consider getting professional help with it.

- The worst case is that your hard drive is seriously damaged - you're going to need a new hard drive and you've probably lost all your saved stuff
- Or, if you're lucky, some essential files are missing or damaged but the rest of the disk is OK.

If you want to try and solve this yourself, here's what to do:

If you have the disk that came with it when you bought the computer, put that in the disk drive slot and try again to start the computer. If the computer still won't start up, you definitely need professional help.

If it starts up using the DVD, the very first thing you should try to do is recover and save (back up) all your saved files. Do that before you try to fix the bad hard drive.

Look on the screen for the icon for your hard drive. If it's there, that's good news because you should be able to find all your valuable files and copy them to an external disk drive. If you don't already own an external hard drive, I recommend that you seriously consider buying one. After you've gotten this mess straightened out, I recommend that you continue to use your new external drive, with Apple's "Time Machine" software, so you always have your stuff backed up.

After you've backed up your files, go to the folder on your desktop for the CD that you booted from and try reinstalling MacOS. If the reinstall works, you'll be back in business. If it doesn't, you'll have to replace the hard drive.

Before starting you will need to make sure you have a small cross-head screwdriver. Also make sure that you do not have wet hands!
Power off the laptop and unplug it. Turn it over so that the base is facing upwards. Now look for a panel with a Hard Disc Drive symbol on it, the symbol will look something like this:

Remove the screws from this panel (making sure to put them somewhere safe so that you son't lose them). You should then see something like this:

Its them simply a matter of sliding the disc drive out from the contacts (in the photo above you would slide it to the left, if it doesn't seem to work one way try the other, it may need a firm push, but don't be too rough). One the drive has been slid away from the contacts, simply lift it out.
The drive will almost certainly be in a "cradle", a metal panel screwed to the hard disc which keeps it in place when the computer is assembled (see photo below).

You will need to remove the cradle, which will involve removing about 4 screws from the long edges. Do not lose the cradle or the screws. Also take note of the orientation of the cradle with respect to the hard disc, as to put the new one in, you will need to put the cradle on the new drive before putting the drive into the laptop.
Just follow the above instructions in reverse to put the new drive in. If you need further guidance, the tutorial below is quite good (its where I got the images from):

Good luck.

Hello,
it is a known issue that these particular drives sometimes don't get recognized by the Operating System, after coming out of Sleep, Stand By, or Hibernation.
Simply try to disconnect and reconnect the drive again in the USB port, if this doesn't work then, Disconnect it from the USB and connect it to the Firewire. if this doesn't work then, Restart the computer.
It should solve the problem.

Hi,
you,ll need to format the drive first.
connect the IDE Cable ( 40-80 Strand Ribbon )
And 4 Pin Power plug ( Molex )
you don,t need an installation disk to do this.
enter the bios setup, and ensure your drive is seen by the computer.
install windows et,c.
away you go.
