So I'm having a weird hard drive issue with my Firewire external seagate 4tb drive. I have two partitions, a 3TB and a 1TB. I use the 1 as a time machine backup. Often the drive powers down to save power, then when it powers back up, it fails time machine backup and says unable to backup because drive is read only. The only solution I have is to unplug the drive and plug it back in then it comes back to life. I have replaced the drive and it still does it, so it doesn't seem like the drive is the issue. Any suggestions\solutions?
