External drive not 'seen'

New MBP. Connecting Maxtor Firewire drive to FW port and it is not recognized. How do I debug this? I removed the hub and the daisy chain config to make sure I was going direct to the Mac.

I actually had the same type of problem on a USB drive. I purchased it and used it for my MBP right out of the box. Used it for months. Then, i was getting rid of an XP box and wanted to back up some stuff, so i used the HD. It would then no longer mount on the MBP. I did not try my MB. I restarted the mac with the drive attached. it then mounted.
strange.

  • FAT32 Partitions on GUID Partition Table External Drive Not Seen in Vista

    I have an interesting predicament. I have repartitioned my external hard drive to have 5 partitions: 2 HFS+ and 3 FAT32. The external drive has a GUID Partition Table. The drive was formatted and partitioned using Disk Utility.
    When I boot into Windows Vista using Boot Camp, Vista will ONLY mount the first Windows compatible partition. For example, if I have two partitions disk2s2 and disk2s3 (both FAT32), Vista only mounts disk2s2.
    The described partition setup worked well with Master Boot Record, minus the bug with Time Machine choking every so often.
    Any ideas on how I can get Vista to recognize these partitions?

    Hi Karl87,
    according to the german computer magazine c't there is a limitation/flaw in the Master Boot Record (MBR:
    Only the first four partitions are shown in the MBR and since one of these entrys is taken by the needed hidden EFI-partition and the next two entrys are taken by the OSX partition, there is only one of your three FAT partitions shown.
    This limitation to four partition entries is quite old.
    See here for further informations: http://en.wikipedia.org/wiki/Masterbootrecord
    To my knowledge there is no solution for this.
    Regards
    Stefan

  • I have my Time Machine on an external drive (not connected to Airport Extreme) and I have an external HD attached to airport extreme. Is it possible to have Time Machine backUp computer HD AND external HD connected to Airport Extreme. How?

    I have my Time Machine on an external drive (not connected to Airport Extreme) and I have an external HD attached to airport extreme. Is it possible to have Time Machine backUp computer HD AND external HD connected to Airport Extreme. How?

    Is it possible to have Time Machine backUp computer HD AND external HD connected to Airport Extreme.
    Sorry, but no.
    Time Machine will backup your Mac, but not the hard drive attached to the AirPort Extreme.
    Time Machine will back up a hard drive only if it is attached directly to your Mac via USB or FireWire.

  • USB External drive not showing in Finder, or on Desktop

    I have two USB external drives from the same manufacturer. One is for regular storage, the second is for Time Machine and movies.
    The first one shows everywhere, on the desktop, in finder and in Disk Utility.
    The second drive shows in Disk Utility only. However, it is functioning fine with Time Machine. So it is mounted. I have tried several repairs, and it reports no fault found. So it is certainly functioning correctly, but a setting or error in the operating system is not allowing it to be viewed in finder, or on the desktop.
    Any suggestions.

    Correction: Title should be Firewire External drive not showing in Finder, or on Desktop.

  • Is their another way like to use my time capsule as an external drive not using time machine?thanks

    is their another way like to use my time capsule as an external drive not using time machine?thanks

    You do not have to use Time Machine.. but the TC is hardly suitable for a NAS.. it has no means to back itself up and is relatively slow. Still that is up to you..
    CCC or Superduper are good backup softwares .. and there are a number of others.

  • [Solved] External USB 3.0 drive not seen under /dev/sd*

    Ok, thought this would be easy but for some reason I cant get arch to see the physical drive. Its a new Seagate 2TB external USB 3.0 drive. I connected it to a windows laptop and it was quickly recognized (ntfs). I then installed ntfs-3g but still cant see it. I then formatted it under windows as ext4, but its still not seen. I tried this with 2 arch PC's, both the same issue. I seen a few other posts and tried a few things like making sure the mod xhci_hcd was running. I have the latest updates on each system. fdisk -l does not show the device at all! I can see and boot to other USB devices fine just not this one, maybe since its USB3.0??
    I noticed here, they talk about maybe USB3 is broke in the new kernels, after 3.10.2 maybe?
    Similar issue: https://bbs.archlinux.org/viewtopic.php?id=126299
    Possible bug: https://bugs.archlinux.org/task/36296
    However, I would think that by now, this would have been fixed as USB3.0 is more common? Other than trying to find a OLD 3.10.2 kernel any other advice?

    Awesome, THANKS!! Yes I got it to work following this and specifically Da_Coynul's post:
    I was able to get my external drive working again by telling the usb-storage module to ignore uas for the device. Here is how to do it:
    First, create a file named ignore_uas.conf in the /etc/modprobe.d directory containing the following*:
    options usb-storage quirks=Vendor_ID:Product_ID:u
    *(substitute your actual Vendor_ID and Product_ID obtained from the lsusb -v command).
    Next, regenerate your inital ramdisk:
    # mkinitcpio -p linux
    Finally, reboot your computer.
    Although this is not a solution to broken uas, at least it will let you use your drive as before hmm

    Thanks everyone...Now I can see the drive, and will work on formatting it with XFS...

  • Seagate external drive not recognised

    I've had this external Seagate hard drive since I got the Mac itself - around 2 years ago. It's worked fine up to yesterday, when it started making horrible noises, and today when I switched on the Mac it told me 'the disk you inserted was not readable by this computer'. I've tried taking out & re-inserting the USB cable, but I fear something more serious has happened. I looked at another thread on this issue here, but it was full of very technical jargon, & photos someone had taken of the hard drive in pieces; I really don't feel competent to take my drive apart to find out what is wrong! I looked in 'Disk Utility', but I have a second Seagate drive which is the Time Machine back-up, so I'm not very sure which drive I am looking at in there. Everything was greyed out anyway, so I could not click on 'repair' or any of the other options. I would be grateful for any ideas or suggestions!

    Thanks; I tried this, & the hard drive is 'seen' by Disk Utility, but not by Finder. See screenshot attached; it's the 'Go Flex' drive I've highlighted. However I can't actually do anything with it in Disk Utility, as all the options to 'verify', 'repair' etc are greyed out. NB: This is the same for the Time Machine back-up drive as well though; no options to do anything.
    I contacted the Seagate support but I guess there's nothing much they can do if it's died. Yes I do have the files elsewhere; but mostly on DVD & very time-consuming to access. & if you're using a supposedly 'reliable' hard drive as your back-up disk then you don't expect it to suddenly collapse after just 2-3 years. This makes me worried about the Seagate drive I'm using as my main back-up!

  • External drive not visible on macbook

    Hi all
    I am brand new to the mac from windows, so far so good! However I have an external hard drive that I want to plug into my macbook and back up onto. Problem is when I connect it it is not "seen" in the finder window. The drive is presently formatted as NFTS. I want to reformat it for mac but unable in the disk utility option as it can't see it! Covered the basics ie drive works and is powered as checked on the (ex) windows machine, so macbook is powering it but nothing more. I have tried reformatting it under windows, the only choice I have is to NFTS. Am I missing something glaringly obvious here. Am sure this may be the first of many posts.....!!
    Thanks in advance

    One basic problem is bus-powered USB drives that require a little more power than the port is capable of delivering.
    I have a WD Passport drive that only comes with a single port cable and mounts fine on any machine I've tried it on.
    I have a SimpleTech Pininfarina Design USB drive. It powers up fine on a Toshiba Satellite with just one port. On my iBook G4 1.42 and MacBook I need to use both plugs (one is designated as "power only" of a Y-cable plugged straight into both native ports. I tried it with the main one to the MacBook port and secondary one to an unpowered hub (with other components) but it doesn't work that way, or with the single plug. It also has a port for a 5V power supply, but I don't have one that will work.
    When it doesn't work, the power light still goes on the drive but doesn't otherwise mount on the desktop or show up in System Profiler. There's enough power for the drive to make a bunch of noises, but that's it.
    Some bus-powered drives have an external power supply port, while others will only take more power with one of those Y-cables. Could you tell us what brand and model? I think people can give you suggestions with that as a starting point.

  • External drive not mounting

    I recently got an Iomega eGo HD (160GB, FW 400/USB 2.0) for backup. I went with the FW since I learned from several Mac forums that the USB ports on my PowerBook (G4 15") were not likely to power an external HD.
    Unfortunately, FW does not seem to work very well either. When I connect the portable HD to my PowerBook, there is action--the light comes on, the HD feels like it's spinning for about 5 seconds, but then it stops. The HD does not show up on my desktop, in System Profiler, or in Disk Utility.
    I've done some simple troubleshooting--checked the connections, shut down my computer for 10 minutes then reboot--but that did not help. I don't have access to another computer right now so I can't determine if it's the HD itself. Iomega's site suggests that some Macs will not recognize drives over 128MB, but that appears to apply only if you're running OS X 10.2 (I have 10.4.11).
    In a nutshell, the HD is not showing up at all, even though it does appear to be getting (some) power via the FW connection. Are there other things I can do? Would a smaller drive solve the problem? Do I just have to get a power cord (which I was hoping to avoid by getting a drive that had FW)? Or is this PB just inherently weak when it comes to powering external HDs? Thanks in advance.

    Hi, Steve, and welcome to Apple Discussions. The symptoms are entirely consistent with the drive not getting enough power. I've seen several reports of this with Iomega drives in particular, even when they're connected via Firewire. I don't know whether Iomega uses particularly power-hungry drive units or bridge chipsets, or what the problem is with their external drives.
    I recommend a) trying a different FireWire cable, and if that doesn't make any difference, b) either buying an AC adapter or returning the drive in exchange for another brand (or assembling your own from a bare drive and an external enclosure kit like this).

  • External drive not showing in Time Machine back ups

    ok, I have several problems, the first one being the fact that my external drive, where I have all my data, is not mounting or sometimes it mounts but soon dissapears. I was not worried at the beginning since I thought, that is why I have time machine, I have all my files backed up. However, the external drive does not show in any of my back ups. It dissapears from Time Machine too so all my previous back ups from the external drive dissapeared too. I have all those backups before. Any ideas of what is wrong? I have 10.5.8

    Thanks a lot. I am sure I am doing somethign wrong but since the external hard drive can not be seen any more, I don't see it either in any one of my back ups. It does not show anywhere.
    Also, my external drive gets detected sometimes, I run Repair Disk, it says it is fine, then it works for a while and then it stops working. I need to turn it off, then turn it back on and again it works for a while. I have run disk utility everyt time when the hard drive works and still says it is ok, then it stops working again after a while. Any ideas with either one of these problem ( or both)?
    Try other ports and cables. If it has a separate power supply, try plugging-it in to a different outlet. Make sure all the connections are secure. Can you try it on another computer?
    Your disk may be failing, or need a firmware update. Check with the maker's website, support and/or forums.

  • External drive not working on iMac, but works on Macbook Pro

    I have read a few different threads relating to this question, with no real luck of a permanent solution.
    I have an external drive that works perfectly on my Macbook Pro. My new iMac will not show the drive though (both with the current software).
    The drive itself shows a power light and appears to be running/powered by the USB port.
    I have tried several ports.
    It does not show in Disk Utility.
    The option in settings is set to show the drive in finder and on the desktop (I have checked this).
    I have tried restarting the iMac.
    I have also had this problem after the iMac has been turned off overnight, and turned on in the morning (and then plugging the drive in after powering on).
    I resolved this issue once by turning off the iMac, removing the power cord for a few minutes, and powering it up again.
    I don't think it should be something I have to do every time I would like to use the drive though - It would be very irritating if I had to do that every time.
    Any advice or options here?
    The iMac has only been used since Christmas day, 2014 - and has had this problem since that day (in which i solved it by the turn off/unplug thing).
    Sorry, I am aware this question has been asked a lot. I haven't come across anything that is giving me a long-term solution to this problem.
    Happy new year!

    Some USB-powered drives are just crappy. They require too much current from the USB and cause the bus to fail or the bus can't provide enough power for it to fully spin up. You can often hear or feel them clicking periodically (like once a second) as they are trying to spin up.
    If this is the case, a powered Hub, external power supply, or Y-cable will be necessary to consistently use the drive.

  • External Drive not showing up in Finder? Can't access files?

    My blue 1TB external WD Passport Drive (whose name is Ralph and who holds all kinds of precious things that I love and can't lose) isn't showing up on my Finder screen. Whenever I connect him, his light turns up and blinks as usual, but I can't access anything on him. I don't even get an error message when I disconnect him without ejecting. I've tried using different USB ports and different cables, but it's not helping. I've also tried connecting him to different computers (3 different macs and 1 Windows 8 PC), but NOTHING.
    I've been trying everything the past few days to get him to work. He shows up on Disk Utility occasionally. I've tried verifying and repairing him through Disk Utility, but it says that the verification could not be completed, or that it can't repair him. It tells me to back up as many files as I can and then restore him, but I can't access the files to back them up in the first place. Also, the partition name seems to have changed to 'disk1s3', which appears greyed out on the Disk Utility screen.
    In regards to mount point, it says that the disk isn't mounted. I tried mounting it by right-clicking it on Disk Utility, but the mount failed.
    I tried restoring him onto another 1TB WD drive (Oscar), but that failed too.
    How can we help Ralph? I don't believe in much, but I believe in Ralph.
    And that's why we have to help him.

    You can call Western Digital, but most likely they will give you the advice they gave another user recently to send it to Drive Savers for  data recovery. Drive Savesrs quoted him a price of $999 to just recover his photos from the drive.
    There is software you can try. Both have demos.
    FileSalvage $90
    Data Rescue $99
    DiskWarrior might be another option you can try. There is no demo. $99.99 http://www.alsoft.com/diskwarrior/
    Drive Savers
    http://hard-drive-recovery-services-review.toptenreviews.com/drive-savers-review .html
    In the future, you need to backup your important data to another external drive just for situations like this. Another option is to use a service like DropBox to upload files. This is mirrored on your drive so it's not always the best option.

  • Reinstall of OS: iTunes Library on external drive not recognized

    I've always had my iTunes library on my external drive. Now that I reinstalled my OS iTunes will not open the library. I've navigated to the correct library using the advanced preferences but that's not doing it. I've tried discarding the existing library in the music folder. Can't seem to find the answer.
    Thanks

    JS,
    I had some trouble following macmenno's instructions, but have had almost complete success. If you DO have your original itunes library file, this should work for you too.
    Background, my situation:
    My harddisk was failing but warned me, so i copied the ENTIRE itunes folder to an external drive. The iTunes folder includes the "itunes library" file, the music folder, and the xml file. This was suggested in a book i have on iLife as the best way to backup itunes to an external HD to preserve playlists, et al. But the book failed to say how to copy the folder back if needed.
    So the first time i naively just copied the entire folder back to the imac (new HD) but itunes failed to "find" it, even though it was exactly where i had deleted the equivalent default (empty) files/folder. Playing around i managed to get itunes to find the music but not the playlists and ratings...i.e., it was not finding the library file.
    Macmenno's instructions:
    I started all over: With Itunes closed, I deleted all three items from the itunes folder: the library file, music folder, xml file. to be safe, i also emptied the trash since itunes seemed to be following the files. But i left the itunes folder in place, albiet empty. Per macmenno's instructions, i then copied ONLY the itunes library file and the xml file from my external HD to the imac itunes folder. I then opened itunes, checked the preferences to be sure it was pointing in the right direction. I then dragged the Music Folder from the ext-HD and dropped it on the library icon in the itunes program window.
    That worked. i have my playlists, ratings, comments, et all.
    Only problem is i now have duplicate listings of all music songs -- one with an exclamation point that doesn't play (apparently came from my itunes library file before i dropped in the songs), one that does play.
    So macmenna, if you are still with us, how can i delete the 3,000 song titles with exclamation points? I tried to click on the column head to sort them all together, then block-mark and delete... but apparently we can not sort on that column head.
    Or did i miss something in your instructions?
    Thanks. and good luck to you JS.

  • New Toshiba 3tb external drive not recognized at startup WIn 7

    My new toshiba 3tb external drive (with wall wart power) is not recognized at start up (Win7). The message I get is that it is a USB storage device but can not be used until it is formatted (I already moved files to it). If I plug it in after start up it's fine and shows up as a toshiba storage device. I've used the 2.0 and 3.0 ports and it is the same problem (it has wall wart power). I have never encountered this problem with any other usb storage device  (an iomega 1tb and a WD 500gb) always plugged in and recognized at start up.
    Thoughts?
