It's perplexing. I am doing remote debugging with someone. I guess I will have to wait until I can see it first-hand. Then, I will try out DiskJockey -- but if the volume works on the PC and on BlueSCSI, I think it should probably work under MacOS SheepShaver.

Yes - I haven't found it useful. Also, the wiki for MacOS doesn't mention anything about adding .hda volumes under MacOS and google searches generate few responses. There is a thread here that implies it should just work...

Does anyone know why a .hda file from BlueSCSI wouldn't work when trying to add it via SheepShaver preferences on a modern MacOS machine? Is there something special about adding volumes to MacOS SheepShaver that is different from the PC? 1. created volume on PC -- works fine under SheepShaver...

Sorry about that. I was referring to BlueSCSI v1, v2 and ZuluSCSI. I think of them as "emulators" because flash is mimicking legacy hard drives on these old machines and my roots are in the era of purely mechanical SCSI. ;) But...a controller is a controller, even if it is attached to a...

@eric Thanks. I replied. And thanks for the update @V.Yakob It's always possible that I screwed something up or the card has an assembly issue. I just ordered 5 new SanDisk Max Endurance cards from Western Digital for comparison. If they don't work, I will return them. And I will...

I tried to reproduce the capacity bug with BlueSCSI v2, but could not. So -- who knows -- it could have been a system, driver, os or other problem. But, definitely look into it. It was strange that a good volume was reporting the capacity of one of the unformatted volumes. However, I still see...

I used the same SDCard (no changes) in a ZuluSCSI with default settings. It correctly sees the capacity as 2Gb on the partition inb question, and I did equivalent transfers to the same area of the SD Card with no reported CRC errors. I duplicated the files on the same partition, then copied...

@eric Hi Eric - I have a new, barely-used Sandisk SDCard and it is generating the CRC errors shown below after formatting with Overwrite, etc. The card is a genuine SanDisk Ultra 16GB Class 10 A1 card that I have confirmed as genuine with SanDisk. It is capable of writing at 20MB/s (on Windows)...

Thanks -- yes, I agree. The Blue Pills appear to be terrible. I have a few left over (and some bare boards) that I was trying get working on the 950. I just have 1 built-up board. I may or may not assemble any others. But, I still have some parts. With respect to mounting at the desktop, a SCSI...

I put together the pin headers for another Blue Pill from the same batch to get the BlueSCSI working again after the failed overclocking/damage. The performance is similar. BlueSCSI (Berg-Powered) - Quadra 950 - FWB3.0.2: The devices are branded as ST, but...? Also, the oscillator appears to...

Part of the problem may be the generally poor quality of the Blue Pill builds/components and/or counterfeit CPUs. My first Blue Pill ended up with a non-functional USB port after only a few uses (no power). Similarly, the 2nd Blue Pill USB port has power, but won't enumerate without additional...

Adding Berg power to the BlueSCSI improves the access time issue and slightly improves overall R/W performance. 1.5ms access time is good. So, there definitely seems to be insufficient power via SCSI alone for the blue pill on my Quadra 950. My guess would be that BlueSCSI always needs Berg...

@eric Do you have any thoughts on why the BlueSCSI v1.1a performance is so slow on the Quadra 950? It doesn't seem able to even clear 1Mb/s. The SDCard shouldn't be an issue and it has been fully formatted. On Windows 11, it sustains writes at ~21Mb/s and reads at ~98Mb/s -- far above Mac...

Thanks. I got it working with the latest 1.1 firmware after using Zadig to install the WinUSB driver for the "Maple 03" USB Serial driver provided by the bootloader image: generic_boot20_pc13.bin noted above. After that, QMK Tools worked fine. However, I'm still digging into the STM32 docs to...

Also @eric , what is the trick for programming the image using the ST-Link Utility or Cube Programmer without going through the USB serial flash process? Is there a different offset, boot config or some other option that needs to be set?

I got it to show up on the Quadra 950, so everything is fine with the programming, but the drives were not writable because of what seem like termination issues with the Quadra 950. If anyone has any experience using BlueSCSI on the Q950, let me know. Here is what I see so far on the Q950 with...

I think the programming is working OK. After programming the bootloader and setting BOOT1, I was able to see the Maple USB Serial device. So, I used Zadig to assign a USB Serial driver, then QMK Tools could see and flash OK. So, assuming the latest v1.1a image is good, then the Blue Pill should...

@eric I am trying to figure out why the programming doesn't seem to be working. Is there anything in the ST-Link/V2 that I'm missing? STM32 option flags or something? I set the BOOT0 jumper, program the bootloader, then set BOOT1 jumper and program the image. But, it seems like it's not working...

Well...the programming seemed OK - got the 5 green blinks after flashing the bootloader. Then, I loaded the image. The problem may be termination on the Quadra 950. I could only previously make it work on the 900. I guess I will try it on a different machine and see if it loads. Also, after...

I finally found my ST-Link/V2 from 2014 and decided to update my BlueSCSI v1.1a (and also program some other BluePills for a build). My ST-Link/V2 is the larger, white unit vs. the small USB dongle. Initially, for my BlueSCSI v1.1-a, I had no luck direct flashing with the QKM Tools, even...
