Low cost Hard Disk interface compatible with Atari ST family computers,
firmware is refined compared to original one;
and tested on a 520ST TOS 1.04, 1040STFM TOS 1.04, 1040STE TOS 1.06, 1040STE TOS 1.62 and 1040STE with TOS 2.06; with ok results.
Results: The unit works perfectly; such example loading the 3.5 MB size of current Metal Slug port takes around 12 seconds (aprox. 650 KB/s read and 400 KB/s write).
Tested against old and modern SD cards, such 1 GB card; 4 GB SDHC and 8 GB SDHC. All these are detected and works correctly!
Operation video,

A video from the user PSIQ, many thanks!

Writing and reading from the hard disk interface:
[video]https://www.youtube.com/watch?v=nERQGIlClAg[/video]
On the last video, a game running from hard disk is shown; with "/" key, a savestate is created. After successful hard disk file writing, the game is closed pressing "*" key, and the STE system returns to desktop. A copy of the generated GS00.TOS file is created, renaming it to GS01.TOS; finally the game is resumed loading the copy of the savestate, GS01.TOS . All these operations are performed correctly.

There are already built units, at marketplace section!

This is an ACSI2STM, right? You say that "firmware is refined compared to original one". Out of curiosity: Where can I find this refined firmware of yours?

Its rewritten in ARM assembly and oriented for C6 family instead C8, to avoid read problems when the hard disk goes beyond 500 KB/s, present in ACSI2STM v1
Compiled using commercial ARM Keil compiler
Due to real C8 are not available from months ago, and C8 clones lack hardware features to use second version of ACSI2STM, such timer 4 features, or defective timer 4 implementation, I hace a CKS32 that fails as v2 version
C6 does not have timer 4 at all xD
Signal management is different here. Compatibility is tested against 12 ST machines, 4 years of STE manufacturing (most problematic ones are STEs manufactured from 1993, last ones I supposse), TT, MegaSTE and MegaST

Can be deleted,

So, it's a 100% re-implementation of the firmware? Quite impressive!

Does it work with AHDI, HDDriver and ICD Pro?

As far I know, users are using AHDI, ICD and most of them Peter Putnik or EmuTOS driver.
Personally I tested Peter Putnik one (fantastic price), and EmuTOS driver (free).
HDDriver is too expensive; we are all from the low cost club :)
I don´t know, no users reported anything regarding HDDriver

Nein, ich nicht!

Ja, so sehe ich das auch. Die HDDriver Software ist jeden Cent wert, zumal bis zum heutigen Tag an Verbesserungen gearbeitet wird. Und Uwe Seimet stets ein offenes Ohr hat. Das kann man nicht hoch genug bewerten.

Dem kann ich nur zustimmen.
@mast-eries : With statements like "HDDriver is too expensive" you will not exactly gain sympathy here. Particularly, since the question was just whether your hardware works with HDDRIVER, which is a simple yes or no question.

Personally I didn´t test it, I am happy with Peter Putnik one and free EmuTOS one
Is not as simple as yes or no, due to yes or no can´t define the answer to the question,
Its an implicit statement in the previous answer,

There is a demo version of HDDriver:

Please take a look, test this version with your hardware and report results. That would be great. Thank you.

+1 auch von mir. Bei HDDriver Updates zögere ich nie, das Geld dafür in die Hand zu nehmen - nicht ohne Grund.

Recently, the hardware is polished, in order to speed up the SD card interface.
Current, rev. B hardware performance is around 1 MB/s read and 700 KB/s write

Over in Exxos's forum there is a discussion about power supplies for the ACSI2STM:
https://www.exxoshost.co.uk/forum/viewtopic.php?f=101&t=5199#p81007
I find it quite strange that people say that they need a 1.2(!) A power supply or that only specific USB cables work, which also indicates a significant current draw. Why would that be? Can you please comment on that, @mast-eries?

1.2 A is not needed,
The cheapest good quality power source I have is a Zapaa brand that provides 5 Volts 500mA, its a 2€ power source, that includes an excellent voltage stabilization, there is almost no overvoltage or undervoltage, despite current comsumption.
There are 20€ power sources that are clearly bad, when you saw them in the scope, you see weird voltage fluctuations. A good power source includes proportional and derivative oputput voltage control, many of them provide only proportional control, that leads to overvoltage/undervoltage (fluctuation).
The device usually draws 40 - 60 mA, with some spikes (up to 150 mA) when you are writing to the SD card. Completely normal.
However, you need a very stable 5 volts line in order to power the device; a peak to peak difference of 200 millivolts is not acceptable.
As user Badwolf told, he is able to drop the voltage to 3.8 Volts, and the device still works ok.
But voltage fluctuation appears to be non good for compatibility.
As well, some users found that bad quality USB cables produce no operation of the device,
Personally I tested one of those, and really bad quality cables damage the 5 volts stability, while others don´t.

I tried to google for that ZAPAA power supply without any luck. Do you have a link or something? thx

Sehr interessant!
In Kurz: wenn der SCSI Standard eingehalten wird, funktioniert auch HDDriver.

Das ist konsequent und absolut vernünftig.
