Zaurus - Hardware discussion / Zaurus C1000, C3000, components datasheet?

« Last post by DiTBho on February 25, 2025, 07:40:38 am »

hi
I remember there were datasheets and partial schematics about the components used in Zaurus C1000 and C3000.

Unfortunately I am not able to find them.

I am going to repair a dead C3000 motherboard
+ flash to be desolder and replaced
+ dead microdrive
in the process I will also desolder the IRda port, and reuse the serial contacts for something else.

Let me know

Zaurus - Hardware discussion / Reviving my SL-C760 in 2025

« Last post by clofland on February 24, 2025, 07:00:38 pm »

Is anyone still here? I have some questions:

I got my SL-C760 a LONG time ago, when they were still being sold new. I would like to "revive" it.

1. What OS do you suggest I try to put on it at this point? I see a few options over the years in the forums, but it isn't clear to me what would be the most stable to use now. I don't need anything fancy, mostly just something that will boot with a minimum of fuss and support my CF Ethernet adapter.

2. I don't have a battery anymore. Is there a way to deal with that? I can get into the sort of "recovery" login by holding D+B. Can an OS install deal with this too? If not, can batteries still be obtained?

Thanks for any ideas and/or discussion.

Hi DiTBho,

does it have to me microdrive? After mine died I replaced it with a CF card. There is even CF to SD adapter that worked fine too in my SL-C3200

Yes. It is required. This was done by a technician.

Ok, darn. I guess I'll be investing in a spot welder. There seems to be cheap ones on Amazon.

For Sale / Wanted / Hitachi HMS360404D5CF00, 4GB CF Microdrive operating at 3.3V and 5V

« Last post by DiTBho on February 17, 2025, 08:38:16 am »

hi
I am looking for a Hitachi HMS360404D5CF00 known to be working with Zaurus PDA or in a 3.3V CF machine (e.g. Mikrotik rb532a router).
Let me know if you have one, or if you know what I have exactly to search.

Thanks

A friend lent me an Hitachi HMS360404D5CF00 microdrive.
Same Hitachi model, and this time it responds to the ATA identify command and to every ATA sector_read command

Zaurus - Hardware discussion / microdrive compatibility

« Last post by DiTBho on February 17, 2025, 08:20:35 am »

hi,
after 10 years of service, my Hitachi microdrive died.

• Hitachi HMS360404D5CF00, 4GB

No problem, I have the full backup of the rootfs, the problem is just replacing the broken disk with a new one.

I bought exactly the same model on eBay, but... surprise surprise it is not recognized by my C1000.
Then I returned the drive to the seller and tried a new one. Same behavior, HMS360404D5CF00 not recognized.
Then I tried a Seagate ST1, ST650211CF, which exhibits even stranger behavior:
it responds correctly to the ATA identify command, but panics on every ATA sector read command

(this is a firmware I wrote for a MIPS32/le router, it has a 3.3V CF, exposing the same behavior I see on my C1000)

Some "OEM Only" drives use the CompactFlash form factor but only provide a 5V IDE/ATA interface.
These will not work in readers or devices which expect a 3.3V interface and full CompactFlash functionality

looking at the Seagate ST1 datasheet, I verified it's LBA28 capable.
I don't see any weird pre-init ATA commands.

(The Seagate 5GB on the CF_usb adapter passed all the badblocks tests!)

So I put both the two new MicroDrive into a USB_CF adapter, to check them with GNU/Linux, and ... surprise both perfectly worked with the USB_CF adapter, which operates at 5V. Badblocks passed, zero error reported!

My guess...the Zaurus C1000 CF module must be 3.3V, while these two microdrives only operate at 5V!

The Seagate datasheet vaguely says 3.3V/5V, however ... on the back of the Seagate microdrive it clearly says "+5V", and in fact it does not work on machines with CF powered at 3.3V.

There is no extra label on the Hitachi HMS360404D5CF00

Comparing the microdrive that worked for 10 years on the C1000 with the new one that is not even recognized (does not respond to the Identify command), no difference is noticeable, same production number, same label...

My guess is there are actually two versions

• Hitachi HMS360404D5CF00, 4GB, 3.3V/5V
• Hitachi HMS360404D5CF00, 4GB, 5V-only

According to Google, not only there are also OEM versions ... but also custom IBM-made versions for their MIPS WinCE-v1.0 laptop (only sold in Japan), marked "IBM Microdrive" but made with Hitachi parts, who also made the Apple iPod drive, and whatever Apple, IBM or Hitachi microdrive you look at ...
... they are not easy to identify as "OEM" or "non-OEM", as there is no indication on the label!

Some Hitachi microdrives made for Apple iPod have a log on the front, usually the Apple logo, which means it is an OEM drive, 5V only, True-IDE only,
but other Hitachi microdrives have no indication at all.

is there a list or something about the microdrive compatibility with Zaurus PDA?
