Introduction

This OneTouch 4 Mini hard drive was bought at a Fry's store in 2007. It has a 80 GB capacity, and a 8 MB Buffer.

The drive has an estimated read/write speed of 28 MB/s

I am tearing this apart so I can put this under Spinrite to fix the drive from a unreadable sector.

This teardown is not a repair guide. To repair your Maxtor OneTouch 4 Mini, use our service manual.

  • The drive's enclosure doesn't have any screws or glue holding the case in place, it has a clamshell-style design that cradles the drive inside.

Image 1/2: Here is the Seagate product overview to the Momentus 5400.2 hard drive, model number [http://www.seagate.com/docs/pdf/marketing/po_ld25_2.pdf|ST980210AS] Image 2/2: Removing the EMF shield reveals a small PCB that plugs directly into the  SATA and power connections of the Momentus 5400.5. It doesn't even have a physical connection to the RFI shield -- it just hangs off the back of the drive itself. The SATA connections to the drive are soldered to the PCB itself.
  • The 2.5" hard drive in the Maxtor OneTouch 4 Mini isn't a Maxtor drive at all. It's a Seagate Momentus 5400.5 LD25.2 hard drive.

Image 1/1: Even though the hard drive's label reads "Not Suitable for Laptop Computer Use", it still works perfectly as a laptop hard drive.
  • Just to keep in mind, taking your external drive apart would void the drive's warranty. It's just something to know if your external drive is under warranty.
