Solved Replace drive in RAID 5 array

Specs: XP, Intel / 2GB RAM
Hello: One of the drives in my raid 5 array has failed and I am replacing it with a new drive. There are three drives total and I'm replacing the one in slot #1 of the carriage. Each drive is the same Seagate 500GB. The controller is a Promise FastTrak TX4310 with four sata ports and the carriage has four slots with the 4th being empty. Some questions:

1) Does the new drive need to be formatted?

2) The raid bios says "rebuilding" but I don't think it's doing anything? The only light lit on the three hard drives in the new one in slot 1. How long should 100GB take to rebuild?

3) I may have plugged the sata cables in wrong. I unconnected all of them from the carriage and am not sure I put them back the same. Does it matter or does the controller know what to do? The controller ports are numbered 1, 2, 3, 4. The ports on the carriage are numbered 0, 1, 2, 3. Should I put controller #1 to carriage #0, then #2 to #1, and so forth?

Thank You

Haven't heard from you in a while.

I never formatted them. Better double check it. We use the older scsi enclosures and we use the software to rebuild it not usually the bios app.

You may have picked the wrong one maybe of the is bad or not being seen. Did you view it in the enclosure bios?

You ought to see drive lights and it seems to take longer than one would think to rebuild them and it takes much longer if the system is under loads. I can't estimate a time but I'd think up to an hour or maybe up to 4 depending. I can't think it would take longer than 4 hours but I have always seen info. I think I did do the bios rebuild and it seems to me it had some sort of dots that went along. The software version used to offer some gauge.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.
