    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?

    Do you know what its formatted in? I had trouble with my HDs until I found out Apple formats all their stuff FAT32 and a lot of stuff you buy in a store or old HDs you might have lying around are NTFS which is a Microsoft thing, so Macs don't use it unless you get something called NTFS-3G

    Not sure if thats the problem, but that helped me.

    Partition Map Scheme : GUID Partition Table
    Format : Mac OS Extended (Journaled)

    Only difference is:

    Owners Enabled : Yes (Partition 1)
    Owners Enabled : No (Partition 2)

    Any ideas? Kinda drives me nuts how it always spins down\power saves, because then when I click the drive there is a 2-3 second wait to open.

    The only thing I would be able to suggest is go into the Disk tool and see if you can change that part about it being enabled?

    I have no idea how to enable\disable, as there is no option for such.
