Replaced the hard drive now it won't power on
The HDD died in my iPod Classic 80 GB a couple years ago. After successfully iFixit-ing an iMac using instructions from this site (and a most excellent new set of tools, also from here!), I decided to go back to this old brick and see if I could get it working again.
I found an 80GB HDD on line for about $80, and followed the instructions from this site to replace the drive. The whole process seemed to go very well, but the iPod will not turn on.
If I do the lock/unlock/men
I've tried charging the device for several days now.
I'm loath to open it up again, given how tricky that is. But I will if it seems like checking connections might help.
Because you replaced the HDD, it's not formatted and needs to be formatted in iTunes in Disk Mode
Turn the iPod on and press the center button and menu button to reset it
Then press and hold the center and menu button to reset it, then press the center button and play/pause button and plug in your cable, it will be in recovery mode, and press restore
Start there and tell us what happens
Now it's time to try and replace the battery and see what happens
If that fails to work for your iPod, then go in and replace the HDD cable
If that fails, the HDD is no good you bought and it needs to be exchanged
joshuaesmith, here is what Apple says "If the iPod for Windows Installer gets stuck at the "Waiting for iPod" message, you will have to close that window and use the iPod Updater to restore your iPod.
Click the X button in the upper right corner of the window to close it.
Proceed with the rest of the installation.
You will see an error message with the number 1628, which indicates that the installation did not complete. Click OK.
Unless you have an iPod shuffle, you will need to restore your iPod using the iPod Updater before you can use it with Windows. The iPod shuffle does not need to be restored to work with Windows." and here is how to restore your iPod "How to restore iPod
Verify that you have an active Internet connection, because you may need to download new versions of the iTunes and iPod Software.
Download and install the latest version of iTunes if necessary.
Open iTunes. Connect your iPod to your computer using the USB or FireWire cable that came with your iPod.
After a few moments, your iPod will appear in the Source panel in iTunes.
Select your iPod in the Source panel. You will see information about your iPod appear in the Summary tab of the main iTunes window.
If you are using a Mac, you will be asked to enter an administrator’s name and password.
A progress bar will appear on the computer screen, indicating that stage one of the restore process has begun. When this stage is done, iTunes will present one of two messages with instructions specific to the iPod model you are restoring.
Disconnect iPod and connect it to iPod Power Adapter (typically applies to older iPod models).
Leave iPod connected to computer to complete restore (typically applies newer iPod models).
During stage two of the restore process, the iPod displays an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remain connected to the computer or iPod power adapter during this stage.
Note: The progress bar may be difficult to see, because the backlight on the iPod display may be off.
After stage two of the restore process is complete, the iTunes Setup Assistant window will appear. It will ask you to name your iPod and choose your syncing preferences, as it did when you connected your iPod for the first time." Once you have the firmware on your HDD you should have access to all the function like disk and diagnostic mode. Hope this helps, good luck.
