So this is a weird one. I've got a 500GB Maxtor external HDD that is HFS+ that I put everything on. I plug it in today and for some odd reason, it isn't mounting. This drive was fine the other day, but maybe it died. So the first thing I do is turn on my old Windows XP machine with MacDrive installed and plug it in. The WinPC reads it just fine, sees all the data, etc. So I plug it back into my Macbook. It lights up and starts turning so I know its active and not in sleep mode. Still nothing. Plug it into the other USB port. Nothing. I plug in a USB mouse and verify that the port is working. So now the drive is making a bunch of noise plugged into the Macbook. Disk utility sees the drive, but has no partitions on it. All options are grayed out except format, basically, so I can't repair, verify, etc. So I'm stuck with a drive I know is good and my Macbook (Leopard) won't see the partition my Windows PC with MacDrive saw just fine 5 minutes ago. Any ideas?
