    - Does it show in System Profiler under USB (or how it is connected if not USB)? You should see the chipset in the enclosure as well as the HD itself

    OS X: About System Information and System Profiler - Apple Support

    https://support.apple.com/en-us/HT203001

    - Just what does terminal list about the drive?

     

    I suspect that there is a hardware problem with either the electronics in the disk enclosure or in the disk itself.

    Hi, no it doesn't show up at all on either computer now. Ive tried changing the leads etc but still nothing. I can get it listed in terminal but no where else. Just says it cant be removed or ejected when i tried that. I think the problem must have came by ejecting it the other day by mistake rather than ejecting it correctly. Sounds silly but i never thought at the time as the computer was in idle. it doesn't

    show up in disk utility only when you do it via terminal. Is there a way i can sort this now?

    HI, no it doesnt well not on the imac anyhow. I see what your saying and when i click on the firewire ports it just comes up with lacie d2 quadra button etc not the actual drive. The drive seems to work as normal but once running just has that buzzing blue light, like its busy. With terminal when you type diskutil list it comes up with the mac hd as disk0 etc n then the lacie as disk1. But when opening disk utility normally it just searches and doesnt find anything. Only finds the internal hd when the lacie switched off. when plugged into the mbp its the same nothing there. would be ok just to format it but cant even do that, all that i need is on the imac really

    I would say that there is a better chance that the drive inside the enclosure is bad vice the enclosure electronics since the electrons reports that a disk is connected.

    Hi,

     

    Yeah its proving to be a nightmare. I took the hard drive yesterday to be tested a local computer store. They tested the lace drive and it came back as no faults and fully working. I have the problem on both the iMac and the macbook where it doesn't see the drive. It doesn't see it in finder or system profiler. In terminal it shows and thats the only place, see below

    i think as i had removed the drive without ejecting it has caused some kind of issue with the computer not wanting to use the drive or see it. occasionally it pops up but then says it's read only which is also really odd.

     

    Can anyone help further with this? Thanks

    Also this is what i found online trying to unmount then remount and then just get this...

     

    Darrens-iMac-2:~ darrenmcgough$ diskutil mount / dev/disk1s2

    Usage:   diskutil mount [readOnly] [-mountPoint Path] DiskIdentifier|DeviceNode

    Mount will mount the volume in the "standard" place (/Volumes), unless

    an optional mount point is specified.

    Darrens-iMac-2:~ darrenmcgough$ diskutil unmount /dev/disk1s2

    disk1s2 was already unmounted

    Darrens-iMac-2:~ darrenmcgough$ diskutil mount /dev/disk1s2

    Volume on disk1s2 timed out waiting to mount

    Darrens-iMac-2:~ darrenmcgough$ diskutil mount /dev/disk1s2

    Volume on disk1s2 timed out waiting to mount

    Darrens-iMac-2:~ darrenmcgough$

    What computer OS and version and type of connection did the computer store use?

    Just how did they conclude that it was OK?

    Im not sure what they used, they said they had tested it and it was coming back with no errors. The last info was just disk identifer info from terminal.

    Hey I've just had a small miracle. The message popped up saying unable to repair lace out of nowhere. It said but i could copy or read from the disk. Went straight to disk utility and there it was. Clicked erase to formate it, 10 seconds later all done and the dam thing has stoped flashing constantly. Now backing up again with time machine oh there is a god lol

     

    Thanks for all the help i guess this might help others

    You may have a loose/poor connection.

    Since you did not find the cause of the problem you may have similar problems later.

    Hi, yeah i know what you mean. I think there must have been some kind of error on the disk that i have now formatted and so far all is good. I do have one slight concern though. You know when your using the iMac and the drive is connected as normal. You eject the disk and sleep due to wanting to plug the external into the macbook to back that up. You do that with the macbook and all is good, then eject from the macbook. I then get a notification from the iMac saying it was unplugged without ejecting. Is this due to macbook connecting with the iMac? whats the best way to do this? Ideally id just plug the macbook in when needing to back up and then just eject that at the end, just it seems to effect the iMac its like i need to eject both at the same time or something seems a little strange but might be more

    It takes a fairly short (but not zero) period of time, while MacOS writes the working copy of the directory from RAM back to the drive. Then the drive can be safely removed without later getting that message.

     

    If the problem persists, try slowly counting to 10 after ejecting and before removing the drive cable.
