I have a server based upon a Tyan S2505T Tiger 200T motherboard with\nPromise RAID controller onboard. After a few years of running with 2\nWestern Digital 120 GByte HDDs in mirrored (RAID 1) mode with Windows\n2000 Server and Small Business Server 2000 installed, one of the drives\nfailed. I removed it until I could procure a replacement. I have been\nrunning the server in single HDD mode until the new HDDs arrived.\n\n\n\nThe new drive is unformatted and I used the FastBuild utility in an\nattempt to rebuild the array using choice 5 in the top level menu. After\n3% of the disk copying has been completed, a message is displayed\nstating the source drive (the original HDD) has encountered an\nunspecified error. The same error is seen after I swapped in another\nspare HDD of the same model.\n\n\n\nI have run a disk error check on the several partitions of the original\n(source) disk and it does not show any problems.\n\n\n\nOne of the partitions on the source disk contains a dedicated Windows\nswap area.\n\n\n\nI have not attempted to delete the existing array. It still exists in\nthe Promise FastBuild software.\n\n\n\nThe original documentation in the Tyan manual is sparse. Is my procedure\nincorrect? Any there any more detailed instructions as to how to\nsuccessfully rebuild my mirrored RAID array.?
