Yes: our flash mod service fits 128GB or 256GB flash storage by mail, on Apple's own software. Add it under Upgrade and save above, with a new battery if you like.

The iPod mini is a separate Apple product line from full-size hard-drive iPods. This is the iPod mini 2nd Generation.

Turn the iPod over: this generation has its capacity engraved on the back, 4 GB or 6 GB. Nothing engraved at all means a first-generation mini, which is a different model with its own pages. The order number settles it too — M9800LL/A, M9802LL/A, M9804LL/A and M9806LL/A are the 4GB units, M9801LL/A, M9803LL/A, M9805LL/A and M9807LL/A the 6GB ones, so an even final digit means 4GB and an odd one means 6GB. This listing supplies a 4GB drive: it fits a 6GB mini physically but leaves it a 4GB iPod, so choose the 6GB Microdrive to keep the original capacity. The capacity lives on the drive, not on the board, so nothing else has to change either way.

That is the expected first screen. A new drive is blank, and the iPod's software lives on the storage, so there is nothing for it to start from until a restore puts the software back. Connect it and let the restore run — a restore erases the iPod, so copy off anything that exists only on it first. If a folder icon survives a restore that actually completed, go back to the hardware: reseat the drive ribbon at both ends, look along the flex for creases, and confirm the drive is seated square and the right way round. If the restore will not complete at all, put the unit in Disk Mode first — reset by holding Menu + Select, then the moment it restarts hold Select + Play until the Disk Mode screen shows.

The iPod can be invisible to Windows: nothing appears in iTunes and nothing shows in the file manager when the cable goes in. When no computer sees it, the microdrive is the most common culprit (hold the iPod to your ear for unusual clicking), then the sync cable; the checks below are free.

Strip the USB bus back to basics: disconnect other USB devices (printers, cameras, flash drives) and try the iPod on each port in turn — a single dead port is common on older machines. Swap in a second known-good cable if you have one, and make sure it seats firmly at both ends. Look at the dock connector itself: dust, lint or corrosion across the pins breaks the connection before software gets a say.

Then the computer side: restart it, bring Windows and the sync software up to date — on Windows that is iTunes for Windows — and in Device Manager, under Universal Serial Bus controllers, enable a device entry that shows a disabled marker, or uninstall and reinstall the entry to force Windows to re-detect the hardware. If a recent Mac does not see the iPod, an older Mac or a Windows PC is the more predictable sync host.

Test the iPod's own side with Disk Mode: reset by holding Menu + Select, then the moment the unit restarts hold Select + Play until the Disk Mode screen shows. A unit that mounts in Disk Mode but not in a normal boot moves the suspicion from the cable toward software or the drive. This generation syncs and charges over USB 2.0, with FireWire 400 as the second supported interface, so if the same iPod and cable work on another computer the iPod side is proven.

Bent or corroded pins are on the 30-pin port itself, which is part of the logic board on this model — the metal bracket only locates it; a damaged port is a logic-board or mail-in repair.
