Topic: Hard drives assigning master, slave and single.

[SClassical]

I have a duo compact flash card IDE adapter and there are jumpers on the adapter that allow me the set 1 compact flash to master and the other to slave. I don't see an option on the adapter that allow me to set both compact flash so that I can combine the 2 cards. I want to make both compact flash cards as a single drive combining the 2 capacities together as a single large SSD. Is there a way to do that in a windows program to combine master and slave together as a single drive if there is no jumper options to do it on my adapter? Any advise will be of great help. Thanks B

I'm using this as an external HD not as a main internal computer HD.

PS BTW I'm using windows 7 so if there is a program in windows 7 that would allow me to combine to master and slave of my external HD together as a single SSD please let me know.

You essentially want to create a (software based) JBOD RAID 0 setup. You're master/slave IDE settings are generally separate of this IIRC.

Hi Thanks..Can you explain to me how to do it? I never done it before..Would I be able to use a program in Windows like "my computer" or "windows explorer" to do this? What are the steps I need to do? Thanks a lot.

Sorry, I haven't used a windows box at home in a good 8 or 9 years now and I don't have admin privs at work. A quick wiki search yielded this which talks about a possible windows solution, but I suspect some googling will probably be more useful.

Are you just trying to get twice the storage capacity under a single drive letter, or do you want it to stripe for performance? The later entails setting up RAID 0 volumes, the former can be just an extender setup as mentioned in the article.

Btw, you are using this as a PC drive (even external) and not connected to a recorder, right?

Hi, Thanks for the link...I will check on it.
Yes I will be using it as an external drive and also as a recorder in my 722..
I put this in my 722

with 2X 32GB compact flash cards...it only saw 1 compact flash because the jumpers only allow me to set one as master and the other as slave...no jumper option to combine the 2 as single. And this thing only works if 2 compact flash cards are inserted..If I only put one in it's not usable..So I have to have 2 compact flash cards. But one of them is not recognized by my 722 because my recorder only see the master one and ignore the slave. I can put a 64GB on the master slot and a cheap old 16MB in the slave but I don't want to buy 64GB because it's too expensive at the moment. So I have to combine the two 32GB cards which I have as one so that my recorder can see a 64GB SDD drive.

One thing is I don't know how the audio will be recorded if one cards fills up...It might be seamless as it goes from one card to another or it will stop or have a fraction of the second break before continuing to the next compact flash...Anyone know if it will be seamless going from one compact flash to the next?

Ok, scratch that then. I thought this was staying in a PC.

At this point, I think your only bet is to plug both cards in, plug the entire thing into the 722 and see if it will format the drive and what the final capacity is. It looks like you get an either or, so I'd just pick one and try.

You could ask SD directly how their box would handle the type of drive you are attempting to devise.  Contact them directly via email or use their forum; they are responsive to all kinds of questions.  I've had engineers call me directly to discuss questions I've had about their boxes.

Firstly, the adapter are not meant for hardware raid, so your work around will be software raid, i don't know about soft raiding in Windows but Mac I'm sure the disk utility will work. Try soft raid and format to FAT32, get a FW/USB interface for your CF adaptor and try it with the SD722 FW.

Why not change the 722 internal HD to a 64G CF with an 2.5 (IDE/SATA??) to single CF adaptor? 2 tracks recording ,speed of the CF is not a major issue unless you are doing 24/192Khz. It will save you alot of power and generate less heat and mirror it off to the SD built in CF.

After soft raid chances are the SD722 will not recognize soft raid, due to the master and slave and soft raid platform, it needs to see a single channel drive. As for the write method of raid, a single file written will be span across 2 drives.

Window 7 Professional Edition comes with soft raid. FAT32 or not?? Thats the question left for you.
