Thank you very much, I’ll try it.
I really hope it will work.

I’m sorry I have no idea for you. You need to get the right firmware for your chip/drive.
Then, start the uploader and it should detect your drive. Remove every other drive prior to do this. Try to connect the device by USB, then by firewire if it does not work.

I have a problem with ministack V3, external hard drive.
Which has a Oxford OXUF924DSb chip.

I can connect to my imac 20′ alum, but it’s disconnected automatically and randomly very often. Also, if I turn on my com while it is on, it does not show off.(I have to turn off and on again). And it suppose to be turned off when the computer shut down, but it doesn’t work. So I try several thing ( change position of heat sensor in the case, clean inside, etc) however I cannot fix it.

I decide update the firmware because the firmware is 0X100.

But now I have no idea how I can do that.
1. I ran ‘uploader’ program but it show the messege ‘flash – flash type not defined’.

Could you help me how I can do this bull shit.

thanks.

Maybe this is due to the manufacturer who thought nobody would get 2 of them…
I just read the ID was computed with the ID of the drive you put inside. I had twice the same drive model (hitachi), so it may be right.

Whoever fault it is, this is a way you can go to correct the problem.

This is not Oxford Semiconductor problem. The manufacturer of the device – who purchases the 924 from Oxford Semiconductor – has an obligation to serialize each device with a unique number. I am not sure how you came to have two drives with the same FireWire ID, but normally you should not have to run Uploader to connect a second device.

Really happy it helped you.
Give a feedback, or write an article I will post in my blog, or give me a link to your blog.

What exact hardware are you using ?

Thanks.

This blog was perfect for getting me over a hump with a Windows issue! I will be writting up an entry myself in the coming week to discuss how Windows which refused to see my external drive correctly can be fixed using your links to the 924 updater and using Unibrain drivers.

Basically the Windows drivers suck. They may or may not work and will very likely cause issues left and right such as Delayed Writes. Replacing these with Unibrain or OrangeWare will give you true Firewire 800 however you may have enumeration problems with some Oxford 924 devices. Using your information as background I was able to hack the 924 settings to enable Mirror Raid on my external case and set the block size to 1024 vs. 4096 which appears is critical to stop delayed write issues.

Did some basic testing right after making the changes which worked like a champ and now have a 40GB backup running as well as an active database running so we shall see in a few hours if my problems are fixed.
