We have a 3TB external USB drive that I am trying to attach to some CentOS5 servers. I have tried an older Dell PE1950 and a newer R310 but

one seems to be able to read the drive. It works no problem on windows servers/workstations and I was able to format with NTFS.
Oh, right, related: it's almost a complete certainty that the drive's *real* blocksize is 4k, but has internal code to present it as 512bytes. When you format the drive, be 100% sure to align it correctly: for parted, tell it 0.0TB, which will put it at 1M. The alignment really *does* make a difference in access and throughput speed.

Don't know where you take this certainty from, but to remind

"4 kilobyte physical sectors, 4 kilobyte logical sector harddisks
4 kilobyte physical sectors, 4 kilobyte logical sector harddisks require firmware and software modifications to function. This type of 4 kilobytes sector disks is currently not supported in Red Hat Enterprise Linux 5"
Have an external 3TB Seagate drive myself in the office for which this is the case.
