Four hard drives on the same Qbide

Postby Giorgio Garabello » Fri Apr 27, 2018 3:28 pm

Many years ago I read somewhere that it was possible to connect 4 hard drives on the same Qbide, an Italian user has confirmed to me that "Nasta" demonstrated this to some meeting.
None of us remember the details, where can I find information about it?
Thanks in advance to everyone.

Yes this is possible. The drives do have to be master/slave pairs to the older ATA specs.

Nasta's new QubIDE design does include four IDE ports to support single devices under later ATA specs.

I'll post more when I have more details in front of me. I seem to recall it was a small PCB with one IC. It may not work on some of the clones if they are not literal copies of the original QubIDE - I don't know.

Nasta is very busy right now (as in, I'm not hearing from him for an unusually long time right now) so....

Giorgio,
I can confirm it is possible to use four drives on qubide even up to 32 drives.
This is exactly why I started the qubata driver for qubide but you need also a little add-on hardware using the expander connector (only old original qubide has this feaure).
I don't know if this kind of add-on really was made for the qubide and if they really worked (I can guess no).
Nasta had published a review on this feature but unfortunately I hadn't managed to get it working.
After a hard work I found that some lines can't be shared between drive couples otherwise drives become fully crazy.
I finally made some modified design and built 2 homework circuits that worked perfectly for me with qubata driver and I am using 2 systems with 4 drives each (1 or 2 cf card, zip unit, hard disk and cdrom) for years.
I always wanted to write some notes on this topic but never had time or saw interested users.
Anyway if you want playing iron man, I could supply some info permitting to build a working device.
Alain
