(Part 1 of 2) Microdrive Adventures: Looking into (and butchering) the Hitachi Microdrive and Seagate ST1 CompactFlash hard drives

A few weeks ago I decided to hop onto eBay and buy a couple microdrives for fun. If you haven’t heard of the term, a microdrive is a hard disk drive that fits into a CompactFlash slot. These were intended to be the future in mobile storage, with 20 GB drives being the biggest around 2006. Of course, these drives proved to be very delicate, and besides, now we get 128 GB microSD cards!

The drives I purchased appeared to be pulled from some old iPod minis. The seller tried to remove the Apple logo with some sort of solvent, but left the smudges behind.

The problem with the iPod mini drives is that their CompactFlash interface is disabled. That is, the drive is really just a PATA drive in a CompactFlash’s body. Few devices that aren’t PCs support CompactFlash cards in this mode.

Being the curious type, I popped the drives into my Sony Clie NX73V, which I still carry with me even though it’s 11 years old 🙂 . It has support for CompactFlash Type I and II (thin and thick, basically), and, according to the properties window in the OS, uses the ATA protocol to talk to the cards. This means it should interface with the cards just fine… right?

First, I popped the Hitachi Microdrive in my Clie. One second after inserting the card, I see a question mark in the memory card’s taskbar icon. No dice.

Then, I moved on to the Seagate ST1. It spun up, but the Clie hung for about 30 seconds before finally displaying “The card cannot be recognized”. However, it did at least enumerate with the OS and I could pull up the manufacturer and model number of the drive.

Hm, well those ideas were dashed pretty quickly. Later, I bought a CompactFlash-to-PATA adapter, and a PATA-to-SATA adapter so I could hook it up to my laptop. From there, I used Hard Disk Sentinel (great software, by the way!) to analyze the drives and see if they have S.M.A.R.T. health reporting…

… and they do, alright! In fact, the drives I purchased were both soon to be dead. The Seagate drive had hundreds of bad sectors and a failing disk head/head actuator. The Hitachi drives had so many reallocated sectors that the drive literally ran out of spares. Too bad the Microdrive didn’t report how many sectors were reallocated though…

The drives themselves were in really bad shape, as seen below:

In the next part, I’ll show the aftermath of both drives. (Content Advisory: electronics gore)

Mini-Ramble: Obligatory filler post

It’s been well over a month since my last post. Some upcoming posts are in progress but none of them are in a state that I’d want in order for them to be publishable.

Upcoming posts involve tearing apart yet another portable power pack, replacing laptop battery gauge chips and perhaps some other related posts if I get to documenting and photographing those works.

There’s no real ETA for these; work on this blog will resume once my depression decides to stop kicking me in the shins every day…
