I had a quick chat with Egor this morning, he'll hopefully have the hdprep software up and running this weekend.
The interface uses its own partition info - so as to keep it as small as possible and not waste space ons code, thus for the interface to use a hdd compatible with msdos the partitioninfo part of the bios will have to be modified (should not be such a problem)
Also I think it wil be best if the bios is updated to LBA access mode, it currently works with CHS.

News from Egor:
He sure is still alive and offered to recode hdprep for the interface. Ha said he lost a hdd with msx stuff (stolen) but still has a lot on his pc. I do not think he is active in msx??
Does anybody know him well? I have his ICQ number if you want to chat?

Some HDs may be detected as MFM or RLL, like this old Seagate, it appears to be right. Try other HD and see if the data change, or with the same hd, the data must be the same every time you restart the computer.
The only way to chech this is formatting and saving data to it...
JP, any news about hdprep? We need it to test our interfaces...
regards,
Silvio

HI
Sadly no good news yet.
I spoke to Egor in ICQ on Wed 9 Feb, he said he finished coding hdprep and improved the rom a bit and would mail it to me. Ever since I have not been able to contact him and have not recieved a mail. Will keep you all posted.
Maybe there is someone willing to write hdprep?
Question who have a finished interface and are waiting for software?

I'm very interested in build this interface.
Of course, I understand that Sunrise is much better than this. But, this hardware is very simple to do, the components are easy to find and the cost is very low.
I think that is a good hardware to be developed and help the MSX community.
Understood the hardware it's very simple. Now, we must understand how the software works. A very good way to start is debug the rom.
Thanks to Egor for the interface idea.

JP, I have a Beer202 (built by DaBest) and was starting to write an HDPREP utility. Should I wait a bit longer?

Searching for some info in the Internet, I found out one article that explains how the interface works: "How to connect an IDE disk to a microcontroller using an 8255".
This document includes info about how it works, IDE commands, limitation of 32 mb per volume, etc. It can be useful to those who want to write utilities for this interface.
Here is the link: http://www.pjrc.com/tech/8051/ide/wesley.html
