Re: Problems with multiple Promise SATA150 TX4 cards

Hi,
Thank  you all for all of your work on this topic.

1) I apologize for my email bouncing. I have  no real choice in dsl service. 
Perhaps I will consider cable to prevent my mail bouncing! :)

2) I am able to hang 10 drives on 3 of the Promise SATA150 TX4 cards. So far 
the construction of 5 raid1's  and mkfs.ext3 is ok without kernel  error.  
All 10 drives are recognized by the promise BIOS (it shows drives 0-9) during 
system turnon. I use two separate 450 W antec power supplies.

If I put on 12 drives, 4 on each one, the promise bios does  not let me go 
further. It hangs. Says something about not able to recognize hardware 
configuration or something.

This may be a hardware limitation, or even a faulty channel or two or perhaps 
one/two  of the  additional drives is not working. I dont know. I did notice 
this  "not booting behavior for TX4" with no adequate hints as to what is 
going on earlier when i tried to hang a for a non funcioning sata drive on 
the card that failed right after purchase". I tried 11 drives also and   no 
go. only 8 or less.


Thank you all and I will let you know what i discover..
