Hi Phill.
Could you please be more specific?
What is working and what is not working?
Why are you saying that mouse and keyboard are working?
Are you able to boot into your client machine OS?

  • Equium L350D - DVD/CD drive isn't recognised

    Hi,
    Having a real problem with the internal DVD/CD drive in my Equium.
    Whatever DVD software I try to use my DVD drive isn't recognised. I've tried using the following : Toshiba installed, Windows Media Player, iTunes.
    This is the error message :
    The specific drive cannot be located. Check the setting by going to Settings->Action settings->Source, or otherwise check that the drive has been properly connect to the PC.
    Hope someone can help !!

    Hi mate
    First of all you should check the device manager.
    The CD/DVD drive should be listed there
    If there is yellow exclamation mark near the ODD in device manager, then you should delete it from the device list.
    Then you should access registry (type regedit) and remove the Upperfilters and Lowerfilters values completely from the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
    After that reboot the unit and wait until Windows would recognize the ODD again
    If this would not help, then I would recommend removing the tools like itunes and other burning applications from the system
    I read in many forums that iTunes etc could affect the CD/DVD drive functionality

  • CD/DVD drive isn't recognised on Satellite Pro L10

    hello. can anybody help with the following ;-
    My DVD drive isn't recognised on my comp and in hardware properties it states that my CDW/DVD driver has possibly become corrupted and needs re-installing or 'updating'.
    the drive(r) is shown as TSST Corp TS-L462A - can i get the updated
    driver download from this site? (is it free?)
    thanks for any assistance
    paul

    Hi Paul,
    You don't say what model of notebook you have, but generally speaking if you are using Windows XP then you will be using the standard Microsoft drivers for your optical drive.
    However, you can download any of the Toshiba drivers and utilities from the Toshiba web-site by clicking on the Support and Downloads section and selecting Download Files. You will need to complete the details of your notebook so that the correct driver list will be displayed (unless you supplied these details when you registered).
    regards,

  • WD Passport drive isn't recognised

    I recently bought a WD 2.5" 160GB Passport Drive for my 15" Alu powerbook, and am running OS 10.4.9. My mac won't recognise the external drive on a USB connection. the drive should be powered via the USB port, but I think there isn't enough power from the one port.
    I've seen other posts which suggest I need a 2 port USB power cable, but can't seem to find anywhere in the UK that stocks em.
    Any ideas???
    The drive will work on a PC, so I know it's working ok.

    Using Firewire is more dependable with no port power issues, plus you can boot from an external Firewire drive, which you can't do from a USB drive.
    Thanks firewire sounds like an option - I'm trying to find out if my passport drive will accept firewire, it doesn't have a port for an external power source.....and.... still no luck with a 2USB cable long enough to fit onto both powerbook USB ports simultaneously.

  • External drive isn't being recognized

    I have two external drives, each one an image of the internal drives. I have moved around my entire stereo and computer setups, new desks, that kind of thing. Now one of the external backups is being 'seen' and the other is not. Both appear to be working by way of lights on the front of them, but only one is showing in the finder as recognized.
    I tried switching out the USB cables and that made no difference, so I ruled out the USB cable possibility. I tried plugging them into different usb ports, no difference. The 'dead' one appears to turn on and has power, is confirmed plugged into the computer, but isn't being 'seen' by the finder.
    It is an IOgear ION external hard drive.
    Any troubleshooting ideas or suggestions on what I can do? I would like to ensure it is working as it is intended to safeguard the video data I have on it.
    I have a powermac G4 1.42 duel, mirror doors, 2 gigs internal ram, latest updates on all software available, using USB 2.0 card/adapter.
    Thanks

    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 10.4.6 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! Also, here is Apple doc.#88338 on getting FireWire to work.
    Good Luck!

  • Tiger, iTunes library on external drive, no longer recognised

    Still using Tiger on the iMac.
    Software update caem up with iphoto/Pro Apps updates and a security update.
    Duly installed the lot.
    When I rebooted my heart sank when iTunes could not find the external drive library.
    Rebooted several times, no joy, thought "why do discs fail a few days after you think I need to back that up soon?".
    At this point also realsied the significance of telling everyone not to rely on AppleTv for a backup, having not backed up recent weeks iTunes Store purchases.
    Tachycardic and nervous connected said drive to the Macbook running Leopard and it worked instantly.
    Back to the iMac, no luck, and after much testing found the drive is simply no longer recognised on the Belkin hub it's been on for about a year. Other identical drives are still recognised.
    Unplugging the hub and connecting the drive to the Mac direct it's recognised again. Absolutely reproducible and I can't explain it.
    Have backed the content up now, but I'm convinced this is related to latest security update or peerhaps Apple team hacking into my iMac after all my negative comments about take 2
    So, I know this may be a bit OT, but then again it is to do with the iTunes library foir AppleTV.
    Any similar experiences or suggestions?
    Good time to remind everyone - remember to back up your media files - these things always happen out of teh blue.

  • Trying to switch start up disks but the external drive isn't visible

    I just got a MBP C2D and trying to boot off the clone of my old system....the external drive which holds the clone is not visible on the list of start up disks.
    my old system was a PPC PB.
    is this fixable?
    regards,
    Eric

    Hello,
    Unfortunately this is not possible. The code needed to boot an Intel Mac and PPC Mac are completely different. You can try to do an archive and install over the drive but I can't promise that will work. Good Luck.

  • Seagate Desktop 500GB External Drive USB not recognised

    When connecting this drive to either a PC running XP Pro or a Mac (MBP) running OS X 10.5 (Leopard) then I can access the drive without a problem. However, when I connect the drive to a Mac running OS X Server 10.6.2 (Snow Leopard Server) then the drive is not recognised. It does not even show up in the Mac's Disk Utility. I am able to connect USB Flash drives and other USB devices to the same Mac (a new Mac Mini 1TB server to be precise) which verifies USB connectivity.
    It looks like there is a compatibility issue with OS X Snow Leopard. Do you work with Seagate at all to correct this issue? is there a firmware/OS X fix?

    Have you contacted Seagate, as they manufacturer the hardware? Do they have any updated drivers or firmware or statement of compatibility regarding Snow Leopard on their website?

  • The WD My Passport USB3.0 portable external drive fails to recognise on 13" MBP Retina, why when it works off iMac 27" USB port?

    Just bought a new WD My Passport Mac compatible drive, USB3.0 cable included.  The drive is not recognised on my 13" Retina at all, on disk utilitiy it comes up as a superdrive.  moved to the 27" iMac, recognised only as superdrive through USB2 hub, connected directly to iMac USB port and disk utility picked up the drive.  Updated all WD driver detail as described in WD manual, partitioned drive and copied data from iMac.  Move drive to connect directly to 13" Retina, and it is not seen anywhere.  Same cable used, smae HDD.
    Is this a USB bus issue, power issue or 13" Retina USB i/f configuraiton issue?

    Thought this may be the issue, problem is the USB3.0 connector is 2 micro USB side by side in a single plastic moulding, have searched for separate USB cables but cannot find them. 

  • Newly Re-formatted iMac Hard drive isn't recognised by my LG Blue ray player

    PLease Help!!!
    I've recently re-formatted my Seagate Go Flex 500 to my new iMac.I Saved all my movies to the iMac then re-installed them back on to my external hardrive.Now when I plug my hardrive into my LG blueray player via the usb port, it does'nt recognise it and I cannot now play my movie collection.I had no problems before with my old Windows XP pc.How can I overcome this problem? Can someone please help?

    Check your BlueRay player's manual, because it sounds like it can only read drives that are formatted MS-DOS FAT-32 or something along those lines.
    I'm not exactly sure because I don't have a BlueRay player, however it sounds like you have a couple of options:
    1. Copy the movies back to the iMac, reformat the drive back to MS-DOS FAT-32 or whatever it was and then copy the movies back to it.
    2. Use two External Hard Drives, one formatted to backup your iMac and then a second formatted MS-DOS FAT-32 or whatever it was for the player. 

  • New 320GB Hard Drive isn't recognised.

    I have a Compaq V6560 which came with a 80GB hard drive (Sata) & I bought a new 320 GB but when trying to re-install Windows 7 it won't recognise drive. Bios is useless as there's no 'advanced' option. The motherboard is a Quanta 30cc & bios is up-to-date I'm sure (F.59) so not sure what the problem is. If there's a capacity problem (i.e. this pc will only allow 250GB) is there a way around it as it seems a bit silly. Thanks.

    There could be a couple of differnt things going on.
    The 320 GB exceeds the limit imposed by HP. On the dv9000 series HP has imposed a limit, based on CPU manufacturer for the second bay (100GB for Intel & 160 GB for AMD) this is according to an HP chat responder's supervisor.
    Your model may be using a SATA I controller that does not detect a SATA II drive (assuming your 320 is SATA II).
    You can read more on the Western Digital site here and a related article here These are from the WD knowledge base
    Good Luck

  • Plz help my external drive isn't being mounted

    I have a WD external hard drive, and it stopped mounting on my MAC. I think it happened when I tried to delete the alias in Mac HD/Volumes/. Now when I plug in my drive it only mounts the alias in Volumes but not the actual drive. When I click on the alias it says that the original can't be found. Anybody know how to fix this? Plz help.

  • My new USB 3.0 external drive isn't accessible over network when plugged into my Time Capsule.

    It is a Seagate Backup Plus 3 TB desktop drive. Every other (USB 2) drive has worked like this, and this one works when plugged into my computer directly. I tried asking Seagate about it, but they said it was an Apple problem if the drive works when plugged directly into my computer. Besides, USB 3.0 is supposed to be backwards compatible, right?
    My Time Capsule software is up to date, but is there some software difference between my 2009 MacBook Pro and my 2008 Time Capsule that allows my computer to recognize USB 3.0 drives but not my Time Capsule? Anyone have an idea about how to fix this?

    Check the documentation on your drive to make sure that it is formatted in Mac OS Extended (Journaled) to work with the USB port on the Time Capsule.
    Your Mac supports other formats, so it is possible that the Mac can "see" the drive and the Time Capsule cannot if it is not formatted correctly for the Time Capsule.
    If you still cannot "see" the drive, it is likely that you will need to use a powered USB hub for the drive...even if the drive has its own power supply.
    Your Mac has a high powered USB port, while the Time Capsule port is not high powered.

  • My USB Flash Drive isn't recognised?

    Today, when using my Macbook with Mac OS X Tiger (10.4.11), suddenly it did not recognize my Verbatim 4GB USB flash drive. What's strange is that when I plug it in, the light on the flash drive blinks as if the computer has connected to it, but it doesn't show up either on the desktop or in Finder. I have tried both USB ports on the side of my Macbook.
    I have tried shutting down my computer and restarting, but nothing has happened. I also know that the flash drive works properly because I plugged it in to my PC and it was recognized. Another thing is, that my Macbook does recognize both my Memorex and Scandisk flash drives perfectly normal. Up until today, there have been no problems with this device. Can anyone help me on this topic? Thanks.

    A few things to check:
    - If you launch Disk Utility does the flash drive show up there as a volume? I once had my iPod do the exact same thing as your flash drive and when I opened Disk Utility it mounted the iPod volume within seconds.
    - If you go into System Profiler does it show the drive being seen through the device tree under USB? The fact that it appears to be drawing bus power is definitely a good indicator.

  • HT1364 Auto-save i-Tunes purchases to external drive?

    I have to use an external drive because my laptop (limited HD/RAM) cannot support my music library (too big).  When I purchase i-Tunes, how can I make sure they save to the external drive and not to the laptop?  I had it set-up when I first started using the external drive, but lately I've noticed that purchases and playlists are saving to the laptop again.  How can I check this and transfer whatever saved, inadvertantly, to the laptop back to the external drive?  Then, how do I make sure that my purchases/library is intact on the external drive AND that future purchases go to the external drive?

    I'm not sure Windows 2000 & iOS go together.
    If you launch iTunes when the external drive isn't ready then the the media folder will revert back to the default path on the internal drive.
    To avoid this problem place the entire library on the external drive. See make a split library portable for more information.
