Wrap030-ATX Says "Hellorld"

In the immortal word of [Usagi Electric], Wrap030-ATX says, "Hellorld". This can only mean one thing — serial I/O is working!

Getting serial working should be relatively straightforward. The UART I'm using is an 8-bit peripheral which needs a Chip Enable and an Output Enable signal, just like the ROM. It's a little slower, so it will need an extra wait state or two, but it should be easy enough to modify the bus controller state machine to address the UART as well. It didn't take me long to add the necessary logic, solder on the new parts, and fire it up for a test run.

Nothing happened.

I went through all the normal steps — double check the wiring, make sure my test leads haven't come loose, make sure the chip is seated properly in its socket and not shorted out …

… I burned my finger. And not just a little 'ow that's a bit warm to the touch', but a proper second-degree burn. That UART chip was hot.

That kind of heat can only mean there is a direct short somewhere in the chip. It could just be a defective part, but since they are out of production and I only have a few on hand, the best thing to do is confirm the problem isn't on my board somewhere before trying another one (and potentially destroying it too).

The PCB layout passed Design Rule Check, so I didn't have any overlapping traces. The schematic didn't have any obvious errors where maybe I had inadvertently tied an output signal to power or ground. This was not an existing library part — it was one that I had to create — so it was possible I had gotten pin assignments wrong.

I pulled up the datasheet and opened the part in the library and started confirming all of the pin assignments matched the datasheet. Bus & I/O pins were all fine; but the very last power supply pin was assigned to Vcc, where the datasheet had it marked Vss. So I had a +5V power supply capable of sourcing in excess of 25A of current running into what should have been a ground pin. No wonder it was hot enough to burn; it's a wonder it didn't release the magic smoke immediately.

This is a challenge. I need to swap a power pin for a ground pin on a PLCC socket. On a simpler project, I might've gotten away with just cutting the trace running to that pin and soldering a bodge wire to it.

… But this is a 4-layer board. There is no mere trace running to that pin — there is an entire inner layer attached to it. My best bet would probably be removing the offending pin from the socket, but depending on how it's constructed, I may not be able to remove the pin.

Through-hole PLCC socket pins are staggered. Some go straight down through the board, but alternating pins make an L-shape so that the socket can have two rows of through-hole pins at a 0.1" grid spacing. The L-shaped pins would be trapped under the plastic base of the socket.

Luckily, the pin in question was the first on its side, so it went straight through the base. I started by bending up its contact, and then with the heat turned up on my soldering iron, I was able to pull it out of the board and completely free from the socket.

I had some wire on hand that was just the right width to match the slots for the contacts in the socket. I bent a flat loop to make contact with the chip lead and shoved it down into the slot. It worked perfectly. I ran it over to a nearby jumper that had a ground lead, and there I have my first bodge wire for this project.

It still didn't work.

This is the part of debugging that is the most frustrating. There's a problem and it takes a considerable amount of effort to identify not just the cause, but also the solution. And then after working through those steps and finally implementing a fix, it still doesn't work because there is another problem. Back to square 1 with debugging.

Why is it not working? It's not burning hot, so that problem was indeed solved. I'm getting data to the chip, and the read/write strobes are functional. The chip select signals are ... wait, why isn't chip select working?

... Because I forgot a chip, that's why. Insert Picard facepalm GIF here.

The UART I'm using is a Western Digital WD16C552. It's a lovely chip designed for 386 era PCs contain two 16550-compatible UARTs and a Centronics Parallel port as well. It is three peripherals in one package. To save I/O on my bus controller CPLD, I used a 74'139 2-to-4 decoder to further break down the address for this serial/parallel I/O chip into the three specific peripheral select signals I needed. And I simply forgot to solder that chip onto the board.

Two headers and one 74LS139 later and finally my terminal came to life. The Wrap030-ATX whispered its very first greeting, "HELLORLD". Serial I/O is working and I can move on to the next step. And oddly enough, I tested that first chip that flirted with fire and it actually still works!

I am racing forward through the countless tests and steps to bring this machine to life ahead of VCF Southwest at the end of June. I am hoping to get it at least running BASIC over serial by that time, but for that I am going to need some RAM. This will be fun because this is my first time actually building a DRAM controller; I've done some test designs before but never actually built them. Fingers crossed I don't run into any show-stopping errors getting it up and running.

My Adata HD330 2TB External Hard Disk Drive Review (with my Paper Dolls) - Part 2 [May 11, 2022]

Hello! This is Part 2 of my new item review, the Adata HD330 External Hard Disk Drive (with my paper dolls).😁

In this part, I'm going to show ya my comparison between my recent external hard drive (on the left) & my old broken one (on the right) is my Western Digital My Passport Essential 500GB.

But before that: I would like to apologize for the long delay. My parents are busying extending our house to make more space 🏠🔨, plus the voting election in my country 🇵🇭🗳️, and of course... Umm... I felt emotional & depressed. The latter was the concern of my 160GB (3.5 inch) hard disk drive's life that was on the line 😟 because I made a dumb decision when I disassemble it & see what's the problem via following instructions without my knowledge about the hard disk drive. That 160GB HDD contains my artworks 🎨🖌️, photos 🖼️ & other files 📁 that are my precious memories from 2016 & beyond, and I can't retrieve them anymore. So, I REALLY NEED to find a good professional disk recovery store to save my files, but it'll be very expensive to pay & I don't have enough money. I guess, I DO REALLY NEED a job to earn my profits. *sigh* Without my precious files, there will be no... ME. And my life will be a downward spiral of depression.😔

Anyway, back to my topic... If you haven't seen my previous part, then please [CLICK ME!].

So, without further ado, let's get started:

1st & 2nd Image(s) ↑:

• [1st Image] As I said in my intro, you're looking at my two external hard disk drives. Despite the design & look, my Adata HD330 is taller than my old WD (short for Western Digital).

• [2nd Image] Another thing was the HD330 had shock & drop proof with built-in silicon case around the plastic shell case & also the interior 2.5 inch HDD, though I still need to buy a rugged hard case for extra protection. Whereas my old WD My Password Essential has nothing but four rubber pads on the back.

Little story 📖: My former BF actually purchased this Western Digital external HDD at the local tech store for me as a token of our friendship, and I was very surprised back then when I was in my high school days. *Sigh* 😌 Memories, I would never forget that moment.

3rd to 6th Image(s) ↑:

• Here are their side to side comparison, sandwich style.

• [5th Image (left)] On my old WD external hard drive, you may notice that there's a tiny hole on the left side. That's the light indicator when plugging the Micro-B USB port through the computer via cable.

• [6th Image (right)] And speaking of ports, both Adata HD330 & (old) WD My Passport Essential are sporting USB Micro-B 3.0 port. Well, actually 3.2 gen 1 port for the Adata HD330, meaning it's far superior port than the old 3.0 variant. (Well, I think) It'll be awesome if the HD330 will be sporting the USB type C cable for a modern look & less hassle plugging than the irreversible USB Micro-B. (Just suggesting)

7th & 8th Image(s) ↑:

• [7th Image] Finally, their USB Micro-B 3.0 cables. On the left is from Adata HD330 & on the right is from WD My Passport Essential, which shows up aging from rust on the USB type-A male, but the male Micro-B was surprisingly quite intact & shine.

• [8th Image] On top of that, the old USB Micro-B cable 3.0 is longer than Adata's short-length cable. Also, that cable strap remains wrapped around, to this day.

9th & 10th Image(s) ↑ [without flash for no. 10th]:

• My paper dolls said that these two external HDs are both blue! 💙Well yeah, of course not because I love blue, duh.😊 One is brand new & the other was very old, due to the signing age of fading WD logo on the front, scratch surface, etc. Not to mention not very functional, and hoping it will revive my old one (hoping my old files remain intact without a single corrupt), anytime soon. As soon as I want the 160GB hard drive will be an attempt to save it first (if possible).🤞😟

Overall:

• Well, nothing new. But, I would say it was a pretty good short comparison between my two existing portable/external HD (not High Definition) or HDD. 🙂👍

• Right now, I have nothing to transfer my files for my next & final part. 😟 So, I'm not sure if I could finish this topic this month (May) or not. But, here's hoping that I will find the way while my 160GB HD is putting in rest mode.

Well, that’s all for now. If you want to see my previous topic from March, as well as my current topic from April, then I’ll provide some links down below.↓😉

[Opinión] La importancia de salvaguardar nuestros datos

Nueva publicación en https://ct2.cl/gB

[Opinión] La importancia de salvaguardar nuestros datos

Por Osvaldo Caviedes, Gerente de Ventas Western Digital para Chile, Perú y Ecuador.

En la actualidad, los datos informáticos se han convertido en una parte esencial del día a día de emprendedores, pequeñas y medianas empresas (PyMEs), las grandes corporaciones y las personas en general. Cada momento, millones de datos se actualizan y se comparten de un dispositivo a otro, por lo que salvaguardarlos eficazmente es cada vez más importante para garantizar un correcto uso de la información.

Realizar copias de seguridad (o backups, en inglés) es una práctica sumamente importante tanto para los individuos como para negocios. Resguardar la información usada diariamente permite comprobar y consultar datos de manera eficiente, asegurándonos de que nuestra información siempre está al día.

Existen varias maneras de garantizar que nuestras copias de seguridad sean las adecuadas para nuestras necesidades, tomando en cuenta qué tipo de información requerimos resguardar, con qué propósito lo hacemos y cuáles dispositivos se adecúan a estos.

Los dispositivos de almacenamiento de tecnología flash, como tarjetas de memoria y unidades de estado sólido (SSD), así como los discos duros (HDD) externos que existen en el mercado, por ejemplo, representan una parte importante de las compras que realizan aquellos consumidores que buscan guardar su información personal. Fotografías, videos, documentos y archivos multimedia son algunos de los datos que este sector de la población busca proteger. Las PyMEs o incluso las grandes empresas, en cambio, buscan métodos de almacenamiento más profesionales, que puedan ayudarles con tareas más pesadas, ya que ellos hacen uso de servidores de información por medio de redes especializadas NAS o centros de datos.

En 2023, Western Digital realizó un estudio para conocer los hábitos de almacenamiento del mercado latinoamericano. Un par de datos relevantes que el informe reveló son que 86% de los encuestados conocen lo qué es un respaldo de seguridad y el 88% de ellos los realiza en dispositivos físicos u online (nube). Además 8 de cada 10 encuestados realizan copias de respaldo de manera frecuente, entre diaria y mensual.

La principal razón que dieron quienes no respaldan sus datos fue que encuentran complicado hacerlo (32%), mientras que el 24% se olvida y otro porcentaje similar no lo considera necesario; Debemos recordar que incluso con los adelantos que han surgido con respecto a la IA, no existe un sustituto que se pueda equiparar a la supervisión personal.

Pero ¿cuál es la manera responsable y correcta de realizar las copias de seguridad o backups? La respuesta corta es que no hay una sola estrategia paraguas que funcione para todos en todas ocasiones. Lo que es útil para un consumidor que guarda sus fotografías y documentos personales no lo va a ser para una PyME con sus registros de trabajo y de empelados, y ni se diga con una gran empresa que necesite copiar o reescribir varios terabytes de datos diario. Aún así, algunas reglas generales que tomar en cuenta pueden ser de gran ayuda para no perder información importante. Por ejemplo, se recomienda tener un histórico de respaldos en vez de sólo una copia: es mucho más seguro conservar varias versiones de la información que deseamos preservar – de esta manera si llegáramos a salvar algo que está mal o que necesitemos cambiar, tenemos la seguridad de que existe un respaldo de información sin el error. Esta forma secuencial de respaldo se puede llevar a cabo periódicamente, asegurándonos de tener copias de versiones anteriores de los archivos que deseamos preservar.

Otro consejo que hacemos desde la compañía es el de tener en mente la regla del 3,2,1 del backup: tener tres copias de tus datos en dos tipos diferentes de medios con una copia almacenada fuera del sitio para la recuperación en caso de desastre. Tomemos como ejemplo tus fotos familiares: la primera copia es tu archivo original y se queda en el dispositivo de almacenamiento original, como un WD My Book. La segunda copia se respalda en un tipo diferente de solución de almacenamiento, como un WD My Passport, un disco duro portátil. Por último, querrás una copia fuera del sitio, así que subes tu tercera copia de tus fotos familiares a tu proveedor de almacenamiento en la nube preferido.

Es importante proteger los datos y convertir esta práctica como parte de nuestra rutina. Desde la compañía te invitamos a experimentar con las diferentes formas de salvaguardar tus datos y hacerlo de manera recurrente.

WD Blue SA510 1TB WDS100T3B0B Failure… Again

Oh my sweet WD Blue SA510 M.2 SATA 2280 blade drives. You are such trash. I had two of these for GeoCities, one master and one backup. However, since I took GeoCities offline I thought I’d erase and sell the drives. But look at what I found when looking at the drive stats with DriveDX. Yeahhh 824 TB of NAND writing (TLC and SLC). That doesn’t sound right. Those retired blocks are usually not a good sign either. Digging a little deeper we find…

A massive 1.8 TB of host writes, GeoCities dataset copied twice. 400 TBW is where WD expected the drive to fail according to the data sheet. Guess I better hook it into the old WD Dashboard and see what it says.

Oh, a new critical firmware update has appeared.

October 27, 2022 – Firmware v52020100 Addresses an issue in which a drive may not be recognized by the computer.

So firmware 52020100 should solve a pretty big issue, not being able to see the drive at all – this is what was installed on both my SA510s. Then there’s this new update:

May 25, 2023 – Firmware v52046100 Addresses an issue in which a drive may enter a read-only state.

Hmmm right, are you still trying to work out how your own tech works WD? I mean read-only is better and possibly explained by the excessive writes going on. Good thing there’s a five year warranty and I have consumer rights against dud hardware.

Through the motions we go. Updated firmware OK, but the drive health is still only 40%.

I guess you can’t bring back the drive from the brink. They’ve improved on the uptime before failure at least. Instead of 600 hours before failure it is now ten times that at 6586 hours. Still only 59 power cycles as the drive was just being used as to host GeoCities – lots of reading. Tech support was less than useful directing me to India who may not be aware of consumer rights. But you’ve gotta feel bad for the people buying lots of these based on the success of previous revision WDS100T2XXX working as expected. For now I’ll just use the other working drive as a throw about spare and wait for it to fail in a new quirky way. If anyone can do it WD flash division can! 💁‍♀️

"How to build a really personal computer," Western Digital Corporation ad in Computer Design Magazine, 1984, via archive.org

Put the "personal" back in personal computers with the WD2001 Personal Chip from Western Digital. Consider the facts: today's personal computer is a shared computer. People in the Modern Office are standing in line to use the nearest PC. John updates his sales forecast, Jane keeps her product plans on target, Martha processes salary reviews, Joe does his monthly report, Teddy wants to write a letter home to Mom-- all on the same PC.

How can we keep their files private and prevent electronic evesdropping? With a Personal Chip, that's how.
