Title: 3" Drive write protect pin
Post by: loco on 19:42, 30 May 11
The latest saga in my misadventures!


Whoever kindly replaced the drive belt in my 6128 also lost the little write pin. Everything is write protected no matter how many times I beg her to 'retry'. I opened it up, shook the housing, and it's not anywhere to be seen.  >:(


I would much rather be in need of a new drive belt than one of these blasted pins. I am guessing there is absolutely nowhere I can get one, apart from another drive. Please tell me I'm wrong! Or at least lie to make me feel better...


Or can I use anything else in it's place?

How about a 3.5" drive? :laugh:

Yep, this is probably the route I will take (I do have a HxC too, but not planning to use that internally)


I just find the lack of such a small, simple part quite maddening given the drive is otherwise perfect!  :o


(Note to anyone with broken drives : please save the pin before you think of throwing it away!)

As a last resort you could always just solde some wires that go to a toggle-switch across the pins of write-pin switch, then you can switch between write enabled/disabled no matter what way the disk is set.

Hey, when I told you my missus had thrown mine away you just suggested going through the trash with a magnet :D

Yeah, I have got a few odds and sods from him. He is a genuine friendly guy actually. Well worth bookmarking at least.

Huh, imagine that!

He's also got some relatively cheap disks - £4.75 for 5 of them...
