Hi Tesserax,
Thanks for the reply.
As you suggested, I tried connecting my drive directly to the Macbook port. At first it was not recognized, so I powered off the drive and reconnected and the Mac connected properly. I repeated that procedure to try to connect it to the Base Station, but that didn't work.
I then ran Verify Disk and Repair Disk and received the message that nothing appears to be wrong. However, the option for Repair Disk Permissions is grayed out, so I couldn't try that.
If it gives you any more clues, I tried plugging a small (unpowered) 1 GB thumb drive into the same Base Station port I'm trying to use for the Seagate, and the machine recognized it immediately and started showing the server connection.
cheers,
