  • Maybe, I’ve only had experience with a few of them, not hundreds… never had any problems with the swingplate. Feeder rubbers, yes, but that’s a common problem on all printers, you just sand those down a bit and they work like new.

    These can still be pretty good if used for home printers, 30K pages without a problem, that’s a lot for home use. You could probably still get one of these for like $100 second hand. That’s not a bad deal considering how good these things are.

    Ricoh are great, but I’ve had bad experience with Xerox. Xerox used to be great, but they dropped in quality the last decade or so. Ricoh are still great though.









  • Because some of these disks were proclaimed worn out and not to be used. I still use all of them in 3 custom NAS builds. I sold 2 of them, the owners still haven’t reported a disk failiure, that was 2 years ago. I use one of the NASes as my personal storage, mdadm in RAID5, I still haven’t had a single disk fail on me. They were all full of “bad sectors” (logical, because of the bad contact between the head/preamp and the control board, bad data was being written to them, passed them with DRevitalize, all of the bad sectors were “reparied”), and yet, somehow, they still work.

    Not to mention the numerous primary (OS) drives I’ve done this operation through the years and most of them still work fine, even though they have fulfilled their purpose (with the advent of SSD and all that). I’ve also compared the life cycle of identical drives that didn’t get this treatment and ones that did. Most of the ones that didn’t get this treatment are dead now (head crash in most cases).

    Do this surgery to all of your drives as soon as you buy them (or at least after they’re out of warranty), disable AAM/APM (wdidle3 in case of WD) (you can do this even if in warranty, it’s a software/firmware tweak) and the disk will practically last forever.





  • The contacts are gold, which definitely doesn’t oxidize…

    This looks like gold plated to you?

    When will people learn, don’t trust everything you’re told, check for yourself.

    The solder doesn’t really add any contact surface area…

    Plase take a look at the two, and tell me the contact area is the same. Solder wire is 60% tin, 40% lead (Sn60Pb40). They are both soft metals at room temperature, thus, they displace when pressure is applied on them, like from a needle for example, and they make a nice bed for the needle to lay in, maximizing surface area.

    …and even if it did, it makes no difference for digital signals…

    Oh, now I just know you know nothing about electronics.

    “Better conductivity” doesn’t improve digital sigs either.

    You do know that it’s not just I/O data that goes through those pins, right? Look at some of the buses on the PCB, not all of them are the tiny, there are a few thay are quite thick. You know what they are? They’re the magnetic coil control pins, the thing that makes the heads move accross the surface of the disk… you know, the thing that fails when there’s a head crash. It takes power to move the head, thus, it’s not just a signal now, is it.

    I can’t confirm the last paragraph, but HDD manufacturers could just move the PCB closer to the chassis and/or make the contacts’ springs a bit stiffer to achieve the exact same thing, which is slightly more pressure between the contacts. That’s literally all you’re getting here.

    Look at the doodle again, and you’ll see I’m right.

    I didn’t come up with this idea on my own, as I said, I looked at how things were done in the past, when drives were really good. Everyone soldered the contacts for the pins back in the day, and then, they just stopped. WD were the first, others followed.



  • They’re not soldered, as in soldered to pins on the aluminium chassis. Look at the image I posted, have I soldered anything from that board to the aluminium chassis? No. The’re solder cushions to act as pillows for the metal head/preamp pins, which leads to having wider contact surface and no oxidation, which in turn leads to better conductivity, no head fly-bys and no head crashes when the head looses contact with the control board.

    BTW, they used to make them with solder cushions, but stopped after a while, cuz those disks could go through hell and back. Remove the boards from some old early 2000’s drives, you’ll see what I’m talking about.
