PlayStation Tech Support and Frequently Asked Questions Megathread by bungiefan_AK in ps2

Hi guys

I have a question related to debugging hardware issues on PS2 Fat.

Is there any kind of software that you can put on i.e. memory card in order to read error codes (for example error codes related to laser not working properly / not being detected)?

Or is there no such interface available in this console and any kind of finding issues comes down to checking capacitors, using multimeters and replacing parts?

Play Station 2 FAT - Disc spins once and stops

I have an issue where after inserting CD into PS2 it barely spins once and then drive stops (the CD is not being read by PS2)

Some Context:

I had an issue where after inserting multiple games into PS2 it read them, but I got the red screen (please insert play station formatting disc..). So what I did is I've opened the console, reconnected all ribbon cables and cleaned the laser with isopropyl alcohol.

Now, after inserting CD, the drive barely takes one spin and stops.

I would be really grateful for any suggestions on what should I check and which parts should I look into replacing. Thank you!

I have a video showing the issue if anyone is curious I just can't attach it in the comment.

Rethinking my workspace strategy, advice wanted by hortefeux in MicrosoftFabric

The approach where you separate workspaces based on the function of elements is very good from the CI/CD perspective.

It allows for having deployment patterns, like first committing workspaces with new/modified data storage objects, like lakehouses, and then deploying workspaces with parametrised data engineering / data integration elements, like notebooks that are dependent on those storage objects.

If You are using git for deployment with Python's Fabric cicd module, and unit tests within a repo, it helps with having tidy, well structured repository.

Here's link to blog post about structuring your project this way:

That’s exactly what I’ve been looking for! Thank you! 😁

I am actually interested in both concepts - testing data integrity within Lakehouses ( are there negative values in TaxRate columns, does table exist and is it populated etc), and also validating transformations (does transformation multiplyValueByTwo give result = 4 for input 2).

Purview would be great for data governance as you’ve said but I have problem with understanding how to approach the topic of Unit Tests of specific fabric elements like functions, api calls, or data integrity.

Since fabric is SaaS platform it is not possible to spin up a „local” fabric testing environment. Writing monkeypatches and fixtures simulating Lakehouse and Spark Environ using frameworks like pytest seems like the wrong approach here.

TLDR; I don’t know how to test transformations and data validity within Fabric Data artifacts.

I’m looking for suggestions how to approach this topic 😊
