Formac XTR Raven 250GB won't mount anymore

Hey all, I've had my Raven for a couple of years now, never had a problem till last night when I reconnected it and it wouldn't mount. Here's what I've tried.
Restart
Open Disk Utility (the drive doesn't show up)
Open System Profile (again drive doesn't show up under firewire)
Repair Permissions
Zap PRAM and PMU
Try to boot into it by holding down F at start up as it has a clone of my disk on it.
Try to open it in Diskwarrior to repair it, diskwarrior doesn't see it.
Thats pretty much everything.
The drive turns on fine, spins up but nothing else, I've changed the power adapter the only thing I haven't tried is connecting it via firewire 400 but I have to wait till tomorrow to buy a 400 wire.
Anyone else having my woes? or any ideas?
Thanks : )

UPDATE
I got a firewire 400 cable today and connected and now my drive mounts perfectly.
It would seem that my firewire 800 cable has given up, or the port, I won't be sure until I get a new 800 cable.

  • External hard drive won't mount anymore

    Dear all,
    I have an external HD that would always mount without any problem on my black Macbook.
    Last month, I upgraded my system RAM from 2GB to 4Gb. It made the Macbook much faster, but also seriously reduced battery life. In a drive to fix this battery problem I reset the SMC.
    Now, I do not know if these issues are related, but the strange thing is that mre or less since then my external drive won't mount anymore. The external drive itself seems fine. And when i plug it into a (powered) USB port of my external display, it will mount. But connecting it directly to the Macbook it won't anymore.
    Somehow it seems like the Macbook's USB port is not giving off enough power anymore. Maybe it's because of the SMC reset?
    Any ideas????
    Thanks

    Hello maccynicwhoalwayshasmacs,
    Thanks for the question. After reviewing your post, it sounds like trouble with an external HD mounting. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

  • Harddrive won't mount anymore

    Hello all,
    One of my internal hard disks (Seagate Baracude 7200.11, 1 TB) of my Mac Pro won't mount anymore. The disk is spinning as normal, I don't hear a weird sound or anything. It just won't mount. Not in Finder, not in Disk Utility and not in Systemprofile.
    I did try diskwarrior and some other utility apps, but nothing seems to work.
    Is the disk just 'dead'? Or is there something wrong with the SATA connection?
    Thanks for helping me!
    Greetz,
    Maarten

    Thank you for the answers. I went to the Seagate website and did a firmware upgrade for the same hard drive that is (still) working...
    The other one is 'dead' but, according to Seagate, the files are still on the disk. I contacted them to help me out. There are people that claim that Seagate will recover for free because it's a firmware problem.
    Thankx!

  • Hard Drive won't mount anymore?

    All of a sudden my external HD won't mount on the desktop? I disconnected it, unplugged it, shut down and waited several minutes and tried over and over. It's a lacie and maybe 7 years or so old. I use it exclusively for my TimeMachine backup. I'm wondering if it's just worn out from the constant hourly back ups? The light just keeps blinking and won't stay on either. Anybody know what the problem is?

    Don't scrap the drive before you check it. Assuming this is a firewire drive, ever since Mac OS X.3.9 the solder connection of the FW port in the Lacie Enclosure would disconnect from excessive heat. Get another enclosure to try the drive in before you toss it. I have dealt with hundreds of these all with the same symptoms you describe. Unfortunately even years ago they would not sell a replacement PC board but often times they were repairable.

  • FW Drive Won't Mount Anymore

    I have a Lacie Porsche 160 GB FW HD plugged into my G4 iMac running 10.4.8. Til this morning everything always worked fine. Then today I tried to access the FW drive and Finder froze with the beachball. Tried to restart and it wouldn't. So I turned off the computer. When I turned it back on, the Lacie FW drive didn't show up. I've restarted, unplugged and replugged the FW cable and power, tried another computer, and nothing works.
    It doesn't show up in Disk Utility or the Data Rescue II demo. It does show up in System Profiler as a unknown drive. And I downloaded the Lacie Update Tool and was able to update it but it still won't work. Any ideas? Thanks.
    P.S. When I turn on the Lacie drive, it spins up for a couple seconds, then kinda does a "click clunk" clicking for about 9 times before stopping making noise.

    If for some reason the FireWire ports aren't acting properly (thus contributing
    to the external FW drive not being seen) you can reset the PMU and that
    should help in cases where the FW port itself goes unrecognized.
    If the System Profiler can see the FW ports and the external drive, but
    you can't use the FW drive, you may be able to get a disk utility to see
    the drive and try repairing it. If the Mac's Disk Utility can't fix it and shows
    errors, you may need to get a third-party disk utility such as DiskWarrior.
    This utility can sometimes fix errors that otherwise may require more
    drastic means to save the drive. Other means can cause loss of data.
    Some damage or corruption on a hard drive may require erasing and re-
    formatting to get it to mount, if an error stops it from being seen. This is
    more indepth than just reformatting, and would usually require one to use
    the Disk Utility's zero-data option; of course, all drive data is then lost.
    There may be a utility that force-mounts an external disk drive, but I
    have not found or looked for one. Back in the SCSI days, there were a
    few good utilities to mount hard drives; I used them.
    PS: The "clunk - clunk" is not a good sign in any hard drive.
    Could be it has physically failed.

  • External USB HD won't mount anymore

    I have a 1 TB HD that has all my media on it and today it's not connecting. In the past there have been connection issues such as:
    when I brought my computer and external to a friend's house it wouldn't mount at first, and after restarting a few times and trying different USB ports it finally did mount. This problem persisted everytime I restarted my mac (iMac G5), and I realized that the problem was independent of which USB drive I used. Anyway, the HD would usually mount after a few minutes. It was mounted last night before I went to sleep. I woke up this morning and entered the password to come back from my screen saver and it wasn't on my desktop. I can't get it to mount and it isn't being recognized in the disk utility or system profiler. I've tried restarting mac numerous times, disconnecting/reconnecting the USB chord, restarting the external, but it still won't connect. Has anyone else had a similar problem or know how to help me!?

    Have you tried using a different cable? Are you sure the power brick is working? Try disconnecting all other peripherals and then connecting the external.

  • Ipod won't mount anymore with 10.2.8...?

    Hi there I recently had to erase an imac G4 and re-install Jaguar on it. It is working fine now except it will no longer mount an ipod.
    Is there a driver or something it needs that might have been automatically installed by software update in the past? It's running 10.2.8.
    Thanks

    It depends on the iPod in question but many iPods need higher versions of iTunes to work, which in turn require higher versions of OS X. 
    Which iPod is it?
    cheers

  • My external HD won't mount anymore on Mac OS, Disk Warrior or TechTool Pro, but appears as "media" on Disk Utility. What do I do?

    I have this 1 TB Caviar Black drive from WD, I've installed it on an external HD case and have been using to store large files like HD movies and old archive things. Its file system is Mac OS Journaled.
    Last year, all of a sudden, it gave me the following error while trying to plug it in: "The disk you inserted was not readable by this computer"
    I was mad and left it for dead while looking for a way to fix it.
    Then, again all of a sudden, it started working again, flawlessly and without any problems.
    It worked well for at least 5 more months and then BAM... same error again!
    I've tried DiskWarrior, TechTool Pro, Disk Utility and nothing... The disk won't show up on any of these apps, except on Disk Utility as a "Media" drive with 0 bytes used and unformatted partition.
    What do I do?
    Could it be the external HD case?

    It could be a problem with enclosure, but it also could be a problem with the drive itself or the drive is possibly corrupted. I would start by contacting WD tech support.
    It may be possible to recover files from the drive using file recovery software:
    General File Recovery
    If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as MAC Data Recovery, Data Rescue II, File Salvage or TechTool Pro.  Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive.  Two free alternatives are Disk Drill and TestDisk.  Look for them and demos at MacUpdate or CNET Downloads. Recovery software usually provide trial versions that enable you to determine if the software would help before actually paying for it. Beyond this or if the drive has completely failed, then you would need to send the drive to a recovery service which is very expensive.
    The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
    Also visit The XLab FAQs and read the FAQ on Data Recovery.
    Otherwise, unless the drive fixes itself like before you should try repartitioning and reformatting to determine if the drive has failed or is now working properly.

  • External Harddrive won't mount anymore

    Hi Guys,
    I recently copied over a load of stuff from my harddrive to my iMac but today it seems not to be playing ball. I've looked up the drive on Drive Utility and it is recognised there except i can't repair, mount or verify the drive.
    Has anybody experienced this before and if so do you know what i have to do to fix?
    Cheers
    Jim

    Zap the PRAM and Reset the SMC and try Disk Utility again. If still no joy, try something stronger, such as DiskWarrior or TechTools.

  • Firewire HD won't mount anymore

    emac running 10.4.7 neither Lacie HDs show up on desktop or finder had been fine till rct. Any thoughts? tried the basics, unplugging etc Thanks- Kav

    Thought you could use this info about getting FireWire to work!
    First, you should always Repair Permissions in Disk Utility before and after any update; I would do that now. If you installed your update with FireWire plugged in, your Mac may not recognize it anymore.
    Try resetting your FireWire ports by disconnecting all FW devices, shut down your Mac and unplug it from AC power (wall socket) for 30 minutes. plug it back in and try FW.
    If that did'nt work, download the combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try. Yours is the 10.4.7 Combo update. Others reading, download the Combo that applies to your system.
    If that still did'nt get it Zap the PRAM. While restarting Mac hold down the following key combo Command-Option-P-R. Keep holding those keys down till you hear the second start-up chime, then release.
    For those of you with Macs that are not PowerBooks or iBooks, a bad internal battery can cause FireWire to not be recognized, so make sure it's good!
    Good Luck!
    Cheers!

  • Time Machine EHD won't mount after update to  10.6.7

    I recently upgraded to OS X 10.6.7. Yesterday, my Time Machine backup failed and the LaCie EHD that I use for my backups won't mount anymore. My husband was able to see the EHD on his PC, so I don't think it's a problem with the drive. I suspect that it has to do with the OS update. Any suggestions?

    If you have a desktop computer: Unplug it from the outlet and anything plugged into the firewire/usb ports, leave it that way for 45 seconds minimum check it again and see if it mounts in disk utility
    If you have a laptop do one of these two steps and post back if it mounts:
    Removable battery: Remove battery, disconnect charger(power adapter), hold down power button for 5 seconds, put back in battery should resolve
    Embedded (non removable) battery: plug in the power adapter/charger, turn off computer, hold down on the LEFT side of the keyboard Shift-Control-Option. While your holding all of these press the power button once, let go of just the power button. Two seconds or so later let go of the rest of the buttons, you'll know this step was successful if it didn't turn on.
    If it doesn't or does show up also post back your answer to this:
    Click on the Apple icon in the top left hand corner, click on About This Mac, click on More Info. Then Click on Firewire or USB (Depending what type of connection your EXHD has) if you see it in the right it's a recognized device, just not mounting, give me a heads up whether you do or don't see it there.

  • My external HD Lacie D2 Quadra will not mount anymore

    Hi,
    Since a few weeks my two year old Lacie external HD (D2 Quadra) won't mount anymore through FW 400 or 800 on my MacPro both in front and rear connection (Usb is working fine though). I also found out that the same external HD still does mount with FW on my Macbook laptop although both machines are using the same OSX.6.8. Also on MacPro  in the system profiler I can't see my FW external device. Restarting and refreshinging PRam didn't bring any solution yet. I've also updated the firmware of the HD to the latest version.
    Does anyone recognize this problem?
    Greetz

    Well I now believe that my whole FW conection is corrupt. I tried different cables and connection through different FW ports (also some in my monitor) and no device corresponds or mounts. In the system profiler I get the message that FW devices can't be displayed. I have other devices that also connects with FW but none of these mount either on my MacPro. I tried several things now such as unplugging all the cables and then slowly building it up and begin to suspect that my FW is done on this machine. It's a pity that you can't test the functioning somehow other than it's not working.

  • My USB CF Card reader is not mounting on my 2.5 GHZ Intel Core i5 iMac anymore. It was last week and worked fine to get pictures from my camera. Now it won't mount. I have tried another card reader and the same problem exists. Also tried different cards..

    Hi
    My USB CF (Compact Flash) Card reader is not mounting on my 2.5 GHZ Intel Core i5 iMac anymore.
    Last week it worked fine to get pictures from my camera but now it won't mount at all.
    I ejected it in the correct way rather than just disconnecting it but now i cannot get it to remount!
    I cannot even see it in the disk utility or system profiler.
    I have tried another card reader (a brand new one bought today) and the same problem exists. I've also tried different cards to see if that made a difference and they still arent being picked up on the Mac. 
    I have done all the usual things like rebooting, unplugging all other USB devices and then trying but nothing has worked.
    I'm a photographer and I'm at my wits end here. I know the cards are fine as i have been using them without issue and they are also new.
    Note: If I plug the camera in directly to the Mac, the Mac picks it up just fine as it always has done. Its just the card readers that it wont pick up anymore.
    If anyone has any ideas at all other than the following (my so called friends advice) you'd earn my undting love:
    Buy a PC
    Use the camera (Thats why i bought the reader in the first place - importing RAW files from the camera is SLOW!)
    Replace your CF cards (I have three 8GB cards two of which i had never used til today and they dont work either!)
    Buy a new card reader (this is the 5th one in two days - none work on the Mac)
    Many thanks in advance!
    LIsa

    OK, restart in Safe Mode, this will clear some caches. It's possible one or more is corrupt. To restart in Safe Mode when you hear the start up tone hold down the Shift Key until you see a progress bar. Let it fully boot then restart normally and test.
    Also I am assuming you have checked Finder - Preferences  - General and see what boxes are checked in "Show these items on desktop." You can also mount an item in Disk Utility, simply highlight it and then look in the File menu for Mount.....

  • External Lacie drive won't mount

    I have a older Lacie 160GB LaCie P3 extrenal drive that I can't mount. There never has been an issue with mounting it before in the method described below.
    Here is what happened:
    I turned the drive on but the firewire was not connected so I turned the Lacie drive off.
    I connected the firewire and turned the Lacie on and the (partitioned) drive mounted on the desktop.
    I was looking through the files when I got the error message that the drive was disconnected without being properly ejected which I didn't do.
    I tried turning the Lacie drive off and on but it won't mount. I get the same flashing light on the Lacie drive that I had before connecting the firewire.
    I tried Disk Utility but it can't see the drive.
    I tried connecting to my laptop but it doesn't mount there either or show up in disk utility.
    Questions:
    Any idea how I can get it to mount?
    Is there any risk of damage to the data by turning it on and off in an effort to get it to mount. I can hear it running.
    Thank you

    LIkely (very) your SATA card is fried inside the box for same.
    External HD are very easy to diagnose. Bad USB cable (on commercial sold USB drives) almost doesn’t exist anymore.
    External USB HD have 4 'parts' (not counting the HD  internals)
    1. USB cable (never an issue anymore, approaching 100%)
    2. HD enclosure.....a plastic or metal box which cannot ever be an issue.
    3. the HD itself
    4. ....and last but not least is the epicenter of 'weak links' ,.....a SATA card/bridge that is connected to the HD inside the HD box, the size of a stick of gum, with SATA female on one side, and female USB on the other side, containing circuitry for data transfer between the SATA on the HD and to USB on the other.
    While these bridge cards are better than they used to be, theyre still insanely unreliable.
    There are literally probably MORE than 100,000 perfect external hard drives out there thrown away every year because people assume the "hard drive is bad" when really they could crack open the HD enclosure, remove the HD and put the good HD into a new enclosure.
    See this video of the SATA CARD, its at 8:55min. http://www.youtube.com/watch?v=2pS_EDsP2KI
    All conventional HD external are nearly 100% like the video above.
    See pic below,..a (much larger) SATA card as found inside a typical HD enclosure ($20 ebay)
    This is the nasty piece pictured below causing all the "crazy" activity seen on external HD, very odd behaviour, some have called it "haunted hard drive syndrome".  Random ejects, random strange vanishing of the HD , especially in mid transfer of data.
    the card attached to the TOP of the HD plugs in, that the SATA bridge

  • Fantom external hard drive won't mount

    I am using an imac G3 with OS 10.3.9. Until yesterday my Fantom external hard drive mounted. I dismounted it and turned it off. I went to turn it back on later and it won't mount. I selected initialize from the dialogue box that says it won't mount and when disk utility comes up it show the two icons for the internal hard drive and just one for the external so I can't do anything with it. Thanks for your help.
