Describe the issue

On SCPH-7000x with IDE to SD adapter soldered, it's not possible to write anything to SD card, file writing may start but will eventually lock. HDD Tester shows modes up to UDMA5 as passed, OPL and wLaunchELF can read data off SD card, but can not write. In another issue here:

#39
djseban said wLaunchELF compiled with MWDMA2 solved this write issue, can you please compile and upload such a version of wLaunchELF for SCPH-7000x with SD adapter?

Same issue here with a FC1307A-based IDE-microSD adapter.

However, I don't think this issue belongs in this repository since wLE uses PS2SDK atad module.
You can't just force MWDMA2 without recompiling PS2SDK.

A custom atad module is in my to-do list

Since I wanted to:

• HDD manager to also inform if HDD is og
• allow deletion of __ prefixed partitions

This will take some time, I'm focused on arcade stuff...

But it wouldn't really fix this issue, would it?
It feels like more of a lower-level issue rather than atad issue anyway.
If I understand atad code correctly, timeouts are handled by SPEED, not by atad.

We're getting into the quirks territory with this kind of stuff...

Those adapters are a bit lying inside their specs that they support udma while actually they only support MDMA. I am not sure how it can be controlled from the module side. Module expects that HDD device supports those modes that it reports. Only possible solution is manually control the mode by user selection.

But they do support UDMA.
HDD reads work perfectly, at least up until UDMA5 in my case with read speeds reaching 25 MB/s when using 512KB blocks, basically maxing out at UDMA2 due to microSD limitations.
It's the writes that aren't stable, causing timeouts with adapter not being detected until a power cycle.
