Upgrading iPod Hard Drives
A number of people have asked about upgrading iPod hard drives — what to buy, how to prepare, and how to perform the upgrade — so here are all the technical details. If you’ve never worked inside an iPod before, this is certainly an advanced tutorial, but don’t let that scare you. Working slowly and methodically, you too can upgrade your iPod and store even more music, photos, and videos.
What to Buy
Which hard drive to buy depends on your specific iPod model, so like any half-decent attempt at an upgrade, a little research will be necessary before purchasing. The main factor that will affect your decision is the height, or thickness, of both the iPod and hard drive. Since day one of the iPod launch, Toshiba has produced all the hard drives employed in the full size iPod lineup. While they currently enjoy a profitable OEM business agreement with Apple, the drives are in no way exclusive to the iPod, and they can be found in many other products, including (not surprisingly) some Toshiba laptops and (perhaps more surprisingly) Microsoft’s Zune player. To allow for some options in product development, Toshiba’s 1.8″ hard drives come in two thicknesses — the thinner has one physical storage platter inside, and the thicker has two. As technology advances, however, the capacity of each platter increases while the dimensions remain fixed. This is good news for iPod upgraders — the longer you wait, the more you can store.
Apple’s iPods are fairly easy to find a matching replacement/upgrade hard drive for, as you can generally tell which thickness drive you need just by holding the device in your hand. If your iPod was the thicker of the series when you purchased it, it takes the thicker, two-platter hard drive (examples include the higher capacity models such as 40 GB iPod and 60 GB iPod photo). The thinner models (like the 15 GB iPod and 30 GB iPod photo) take the thinner hard drives.
The new iPods with video capability are a different beast, as the drive technology and space requirements have demanded smaller hardware. With that in mind, Toshiba engineered a new connector on recent drives that is vastly smaller than the previous models. These new drives sport a Zero Insertion Force (ZIF) connector, which, unlike the older iPods, requires no pressure to connect the cable. Simply holding the hair-thin ribbon cable in place and folding down a clamp-like lock will secure all 40 pins in a staggeringly small — and fragile! — connector. The connector on the new iPods’ logic boards is now no wider than your thumbnail, and it, too is quite delicate. Such is the way of ever-shrinking consumer electronics.
Tools of the Trade
Before you decide on a hard drive, you’ll also want to purchase a few tools to ensure the job gets done right. While you’re able to pry most iPods apart using a tool as simple as a butter knife, the professionals use the following to make entry, upgrading, and close-up as seamless as possible.
* Apple’s “black stick”
This nylon-based pry tool is key to almost any iPod upgrade, as it provides a strong lever to get into the edges of the case, while its plastic properties leave next to no marks or chewed-up spots along the edges. Best bought from Stanley Supply & Services.
* IC puller or hemostats (both available at your local RadioShack)
Either of these tools will work for undoing the iPod battery cable and handling some of the smaller pieces of the iPod. Not necessary, but highly recommended if you plan on doing more than one upgrade.
* A straight razor blade (for 5G iPods)
I was hesitant to include this, as it’s a recipe for injury if you’re not careful. In the interest of completeness, though, it’s here. The latest iPods are sealed very well, and more often than not they require a very thin and flexible bit of metal to make room for Apple’s Black Stick pry tool.
* HD adapters from Addonics: 1.8″ to 2.5″ IDE and 2.5″ to 3.5″ IDE
To do testing or erasing on iPod-size hard drives, these adapters will get your 4G-or-earlier drive hooked up to a desktop computer’s IDE bus. (For 5G iPods, see this post) Also not necessary, but again, these are recommended for advanced testing and erasure.
Picking a Hard Drive
Depending on your iPod thickness and model, you can choose from the hard drives in the table below. Note that some of these models are not used in iPods, but should work just fine (for example, the 20 GB ZIF drive, which will only connect to new iPods which start out at 60 GB from Apple — technically a downgrade, but listed for compatibility information).

You can find many of the above drives on eBay and online retailers, but the most prevalent ones will be models used in iPods that shipped in the past. I have used non-Apple-branded Toshiba hard drives without issue, confirming that there is nothing particular about them, except an Apple logo on the sticker. Having a third party manufacturer such as Toshiba re-brand a product is nothing new to the computer industry — other big companies like Dell and IBM work deals like this for many components in almost every product.
Hard Drive Preparation
Unlike my iPod Super hack, a replacement iPod hard drive does not require any special formatting or filesystem preparation. In fact, I’ve found that working with a completely empty/zeroed hard drive works best. If you decided to purchase the adapters listed above, you can connect them as detailed in my Really Testing iPod Hard Drives post, and completely erase the hard drive using the handy Darik’s Boot and Nuke utility (see the comments on that post). I’ve found that it works best to have a zeroed hard drive, but it can usually be done without. (The iPod sometimes tries to find software on the hard drive, which may be incorrect for its generation or be corrupted).
Opening the iPod
To get at the old hard drive, you’ll need to open the iPod, which is usually the hardest part of the process. 1G through 4G iPods aren’t as tough as the newer 5G and later iPods, and can be popped open by pushing the metal backing one way while pulling the plastic front the opposite way. In doing so, you create a small gap where you can slide in the nylon pry tool and undo the five plastic clips along one of the two longer sides. The inside top and bottom of all iPods are not secured. Other World Computing has some detailed take-apart videos which should help give you a good idea of exactly how to get inside.
To open a 5G or later iPod, try the first technique above, and use a razor as a last resort. For the really tough ones, work the sharp edge of a new razor into the side seam where the front plastic and back metal meet, and tip the blade towards the front, using the narrow plastic side wall as a lever to forge a small space to insert the nylon pry tool. This is extremely dangerous! Not only are you working with a super-sharp piece of metal, you’re flexing its brittle structure, which may cause it to shatter — so don’t try too hard. Thankfully, I’ve never gotten cut or had a razor shatter while doing this, but only because I took my time and didn’t get my fingers near the sharp edge. Moving slow and thinking smart (as smart as bending a razor can be) are keys to making this technique work. Once the tool is in and has a little room to work, carefully remove the razor and set it aside. Use the pry tool to work the rest of the side open.
The Switch
After cracking the side of the iPod open, carefully disconnect any audio jack or battery ribbon cables attached to the back panel. Undoing these connectors often requires the use of the nylon pry tool again, or careful pulling with hemostats. The hard drive is then exposed. 1G through 4G iPod hard drives can be unplugged by simply pulling the connector straight off the end of the drive, whereas the 5G and later iPods require you to flip up the narrow lever (it hinges lengthwise along the edge) and unlock the cable.
Install the new hard drive in the same direction as the old one, making sure all pins and plastic guides line up perfectly. 5G iPods are especially tricky thanks to the ZIF connector. Yet again, some tiny tools may come in handy — just be sure to work gently with its delicate little ribbon cable. Move the metal back panel close to the iPod and reconnect all the cables you unhooked to get into the device, and snap the panel back onto the plastic clips.
Restoring in Disk Mode
Pressing any button will power on your iPod, and you should be able to hear the new drive spin up. Unless the drive is preloaded with the correct software you will get a “sad iPod” face. This is OK. Reset your iPod using the commands detailed here, and immediately hold the Disk Mode keys as soon as the screen blanks for the reboot. This may take a few tries, but as long as your iPod doesn’t have the correct data on the drive, you’ve got all the attempts you need to get into Disk Mode. When done properly, you’ll see “Disk Mode” at the top of the iPod. You can now plug the freshly upgraded iPod into your computer and launch iTunes. After it’s detected, iTunes may complain about a corrupted iPod, or one that needs to be Restored. Dismiss the dialogs and browse to the Summary tab for the iPod, and click Restore. iTunes will load the proper software onto your iPod, and it will be as good as new — with more capacity!
