Hello everyone! I haven't been here in a while because I just haven't had any Mac issues. Now I do.


I have a 1 TB WD external HD that won't mount. I connect it via firewire to an Old G4 Sawtooth running OS 10.5.8. My mac sees the drive, it just won't mount. I've also tried to mount it via USB, but again, my system sees the drive, but won't mount it. I inadvertantly disconnected the firewire cable, which I didn't realize for several hours. I reattached the cable, tried to mount it, and nothing. I ran disc repairs, and Disc Utility actually told me the drive was successfully repaired. Again I tried to remount it, but nothing. I repaired permissions, and this didn't work. I've tried different cables, and this doesn't work.


I don't have another Mac to connect it to, so I don't know if this would work. Here's where things get a little wierd, but interesting. I connected it to my PC laptop, and it mounted. Now, this is a drive that was formatted Mac OS Extended (Journaled) on my G4, so I have to use Mac Drive so my PC will recognize and mount The Drive. So My PC sees The Drive as Mac OS Extended, and mounts it. All files are in tact, and the drive runs normally. This is a music drive and it plays normally on my PC. Meanwhile, if I try connecting it back on My Mac, the name of The Drive randomly changes from 931.5 GB WD to 931.5 GB WD My Media Book. I believe My Media Book is the factory name of The Drive before OS formatting. The Volume name remains the same on my G4 each time I've tried to mount it.


I do have another identical drive that mounts from all the bus ports on my G4. Any ideas here? Can I get my Drive to begin mounting on my G4 again? Any and all answers are appreciated.

Sawtooth G4; 1.8 GHz Dual 7447A; Radeon 9800/128MB; 2GB Ram, Mac OS X (10.4.11), Seagate 200 & 500GB HD; WD 120GB HD; Lacie DVD±RW; 550 Watt PSU

    Hi, I assume you were trying to mount it in Disk Utility by highlighting it & clicking on the Mount icon above?


    In Finder's Menu, select Go menu>Go to Folder, and go to "/volumes". (no quotes)


    Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.


    Does it show there?

    I don't think you can do that, & my guess is the PC changed it somehow.


    Might try to mount it in Terminal, like the last post here...

    I'll try to help with terminal if you need it when you get back.

    As I understand it there are two forms...


    diskutil mount disk0s1


    diskutil mountDisk "DriveName"

    Good work!


    Open Terminal and type these commands carefully with the spaces & change 320GB HD to the name of your drive.


    sudo chflags 0 "/volumes/320GB HD"

    sudo chown root "/volumes/320GB HD"

    sudo chmod 1775 "/volumes/320GB HD"

    sudo -k
