Ok....so after installing "smartmontools" on my CentOS machine...and connectiing this drive externally...i got positive reports from both the short and long tests...so the drive can obviously be "seen"....but when I look for it in the /dev/ directory...it doesn't show up.....I'm about to give the fdisk command line tools anonther shot....it allows me to format the drive...and to give it a file system...(ext4)....but it doesn't automaticcaly mount, nor can I format the drive using the Disk Utility in CEntOS.....I'm going to give D.B.A.N one more try since I was able to format it from the smartctl command line....hopefully it will "clear" whaever is locked up. if not...then I'll move onto the other recommendations and advice given by you "experts"! LoL! Thanks for all your help.....will kepp you posted.

Is it USB powered? If so, maybe try another USB port... Did you check /var/log/messages for detection messages?

Take a look at the kernel ring buffer using dmesg when attaching the drive.
dmesg | tail
As you've noted, connecting the drive to an internal SATA port makes the drive be detected (you can run the smartmontools against it).
give the fdisk command line tools anonther shot....it allows me to format the drive...and to give it a file system...(ext4)....but it doesn't automaticcaly mount, nor can I format the drive using the Disk Utility in
This is a disk added post-install, so you'll need to manually add the device to /etc/fstab. There might be a gui for modifying fstab, but I don't use one.
CEntOS.....I'm going to give D.B.A.N one more try since I was able to format it from the smartctl command line....hopefully it will "clear" whaever is locked up.
Maybe some partition on that is auto-mounted? ( Or _unlikely_ software raid metadata? )
Check using the 'mount' command.

Unless the syslog daemon is set to log the kernel ring buffer to /var/log/messages, it won't make its way to the messages file.
