Extermal Toshiba USB 320 GB HDD not recognised correctly

My hard drive does not now recognize itself as a hard drive anymore just a Cypress AT2P RC42 and so is now useless after a couple of months use.
I have uninstalled and reinstalled through device manager. I then tried it on another computer and I have the same problem, therefore it is the hard drive and not the computer.
It is an external USB toshiba 320GB drive which previously worked fine but now thinks its something else and nothing else.
What can I do to rectify this problem? Please help all my data is on this drive.......

  • Upgraded to msata but now original 320 Gb HDD not recognised

    Hi all
    I just upgraded to a msata which works absolutely fine. However the HDD refuses to be recognised in BIOS or in windows 7, I just get a 2100 error on booting. I can boot into windows after pressing a few keys but the hdd is nowhere to be seen in windows. Is there any way to refresh the hard drive list or do a low level format?

    No it's more complicated than that.
    I replaced the original HDD with a Crucial C300 256 GB SSD but that died when I put the laptop down on a worktop one day. At the time I thought it was the loose battery that had turned off the laptop.
    I am doing a RMA on the SSD to get thta replaced. In the meantime I thought I would put the old drive back in and add a msata to get better storage space but the old drive refuses to be recognises by the laptop. The msata works perfectly and is only slightly slower than the C300.

  • USB 3.0 port not recognising USB 3.0 external HDD

    My HP Envy 14 Spectre does not recognise my new USB 3.0 external HHD when I plug it into the USB 3.0 port. I'm using Win 7 64-bit.  I've only recently purchased this ultrabook and today was the first time for me to plug in a USB 3.0 external HDD (which works fine when I plug it in the other port which is the USB 2.0 port).

  • 1.5TB external HDD not recognised on various laptops

    Hi,
    I was wondering if anyone could help me.
    I bought my toshiba 1.5 terrabyte external harddrive just over a year ago. It works fine on my other laptop and my boyfriend's laptop but when I connected it to four other new laptops (all different brands) recently it was not recognised on these laptops at all.
    Is there something wrong with my external or is something on these computers blocking it from being recognised? Do you know how I can fix this problem?
    Many Thanks!

    Hello
    And if you connect the external HDD to your and boyfriends notebook everything is still ok? You have only problems with new notebooks?
    Well thats really strange Have you tested another USB cable and different USB ports?
    Maybe on the new notebooks the antivirus or firewall program is blocking the access to external drive. Check your security software and allow external devices.

  • External USB 3.0 HD not recognised on Kirabook

    Just got my Kirabook, i7 touchscreen, everything is perfect but for 1 thing: my external hard drive - WD My Passport 500 GB USB 3.0 is not being recognised, no matter which USB port I am using. It is not showing in the device manager also or any other screens. Is it a problem with the power of USB ports?
    Same disk is recognised perfectly on my old Sony Vaio Z...
    Solved!
    Go to Solution.

    Just got my Kira and having a huge issue with this.  USB 3.0 drives showing up in Device Manager but not mounting.  Only 1 out of 3 types of USB 3.0 drives my office is using is mounting.  Drives which don't work are:
    Hitachi Touro Pro USB 3.0 500GB
    LaCie Rugged USB 3.0 / Thunderbolt 1TB
    Those drives works pefectly under Win 7 and Mac OS.
    I am not sure if the Hitachi is compatible or not with Win 8 but the LaCie is said to be Win 8 compatible on LaCie's product page.  Looks like a hardware compatibility, may be a BIOS update or mother board USB comptroller update will resolve.
    Tech support is on it, hopefully, they'll find a solution quick.  I can't use my Kira without support for those drives

  • Ms-6741 + SATA HDDs not recognised by xp setup

    Hi all, i have been ripping my hair out for 24 hours about this machine.
    It is a TINY PC with a MS-6741 mainboard. It previously had 2 SATA HDDs installed, both 200GB. 1 had XP installed on it and the other just data. The OS disk failed, many many bad sectors and errors. I bought a new SATA HDD (WD2500AAJS) and thought i would be able to install xp from either the tiny restore disk, or a standard windows xp disk. But I can't!
    First problem (although not the worst) is that the BIOS does not recognise the 250 GB new disk, not one bit. Checked the sata cable, checked the power, checked the disk in another machine; all fine. So after some swearing I decided to copy the data off the data disk and use a disk the BIOS was recognising.
    The mobo recognises it fine, but when i get to the xp setup to select disks and partitions it says 'no disk available'.
    I did some reading and many people suggest that the XP setup disk doesn't have drivers to make SATA work, they suggest downloading the raid/sata driver from the mobo manufacturer website and pressing F6 at the start of setup, copying the drivers to a floppy and letting xp setup find the drivers and use them. I tried that, i tried both the drivers listed for raid on the MSI support page for this mobo, i tried getting the drivers for the VIA VT8237 SATA controller, they didn't work.
    I have tried upgrading the bios, flashing it from a win 98 boot disk, following the instructions on this page http://www.msicomputer.com/support/BIOS_NON_FAT.asp This as far as i can see didn't work, it launched the flash utility fine, said 'deleting' and then 'programming' and said both had completed successfully. I restarted, went into the bios and the bios version hadn't changed. The only difference when i turned it on was that it said 'CMOS settings wrong'.
    I am at my wits end, i have no idea what else to try. I read somewhere that TINY used to make their own version of BIOS which only allowed certain HDDs, maybe they stop you flashing the bios, certainly there is no setting in the existing bios saying, 'protect bios' or 'don't allow bios flashing'.
    I would greatly appreciate any help.
    Many Thanks
    James

    There you have all drivers for your board.
    You probably have to make a driver floppy and load it during install with F6

  • When connected to computer windows 7 by USB the device is not recognised

    While trying to download from itunes to iphone I connected iphone by USB to laptop VAIVO with windows 7 the itunes does not recognise the device.

    If you have the retina display iPad then it's an iPad 3 (or 3rd gen iPad, not an iPad 2 3rd gen) - the iPad 2 was the previous model.
    As far as I know sharing the wifi connection with another device or computer isn't possible. If your computer doesn't have built-in wifi then you should be able to get a USB wireless adapter for it that will plug into one of its USB ports, which should allow it to connect to your wifi network - I use one on an old desktop computer.
    e.g. from Amazon : http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Daps&field-keywords=u sb+wifi+adapter&rh=i%3Aaps%2Ck%3Ausb+wifi+adapter

  • USB External HDD not recognised in OSX 10.5.4

    Hi,
    I am attempting to use an ISOGEAR250 2.5" IDE external HDD on my iMac.
    This deviceis advertised as 'compatible with OS/X', which is in fact only true up until version 10.4.9.
    The device is not detected on any OS/X version with the IOUSBMassStorrageClass.kext or IOUSBfamily.kext kernel extensions of any version of OS/X past 10.4.9.
    The only way to get this device to detect on Leopard is to revert the specific kernel extensions to earlier versions, and use the USB Prober utility. This is quite a dangerous exercise, and can lead to operating system instability.
    I have tried the device on numerous Apple computers, and it only works on the ones with OS/X 10.4.9 or earlier installed. I have also experimented with many different file system formats. This device works fine on Windows machines, including Windows in Bootcamp, and Windows using VMWare or Parallels.
    For your information, the device does turn up in the System Profiler with the following info, but will refuse to mount with kernel extensions past version 10.4.9:
    USB4500 FW1.04:
    Version: 0.001
    Bus Power (mA): 500
    Speed: Up to 480 Mb/sec
    Manufacturer: DATAST0R Technology Corp
    Product ID: 0x4500
    Serial Number: 1966XXXXXXXXXXXX (I added in the X's)
    Vendor ID: 0xed06
    If I plug the HDD in while my iMac is sleeping, it will wake up the iMac.
    I have tried the device on both the iMac's built-in USB ports, as well as with a powered USB hub.
    Numerous other users have had similar of the same problem
    (see: http://discussions.apple.com/thread.jspa?messageID=7835455), and yet Apple has not yet rectified the problem, which is clearly arising from the update to the operating system, and not the device itself.
    Does anyone have a fix for this problem, aside from reverting the kernel extensions and using the USB prober?
    Thanks for your help,
    Cal

    From searching the web, I am tempted to say the Iso Gear is quite an exotic device.
    It's up to Astone them to deliver a firmware upgrade for their device to work with Mac OS X 10.5, as Apple probably follows USB 2.0 standards when accepting (or not) an external hard drive.
    diskutil became more picky in 10.5 (been bitten myself) but still, I am not sure whether this is due to Apples development teams faults or due to to Astone following standards.
    There has been an issue in 2006 with LaCie drives on OS X 10.4 which were resolved by their firmware upgrade.
    I know this is of no help to you, but consider not just talking on Apple forums about this but also on Astone help channels.

  • External USB-hdd not recognised by Finder if connected to Time Capsule

    Hello!
    I'd like to connect a small external harddrive (40 GB) to my Time Capsule (1 TB) via USB.
    I've read on http://www.apple.com/timecapsule/wireless.html the followings:
    "... +And if you want to share both a printer and an additional hard drive, you can. Just connect a USB hub to Time Capsule.+ ..."
    While I've connected two printers to Time Capsule - so I already use a USB hub - I've tried with the external USB-harddrive, but it wasn't recognised neither by the Finder, nor by the DiskUtility-app. The external USB-harddrive appears not even if I connect it directly to the Time Capsule!
    Restarting the Time Capsule / USB-hub / external USB-harddrive / my Mac doesn't change anything
    The external USB-harddrive appears only in the AirPort-utility app (5.4.2) in "manual Config" - "Devices", but even here only as a possible archiving device for the internal Time Capsule harddrive.
    The USB-harddrive itself is formated as Mac OS extended (journaled) and it works like it should on my iMac (3.06 GHz, Mac OS X 10.5.7).
    Do you have any idea why the external USB-harddrive doesn't appear when connected to the Time Capsule?
    Thanks!
    Regards,
    Vlad

    Vlad, this might help...
    *Accessing External Hard Disk*
    Open a Finder window
    Select the Time Capsule in the Sidebar on the left.
    Click "Connect As..." in the upper right of the window.
    Enter the Name of your Time Capsule & its' password (Note: NOT your own Username & password).
    Check "Remember password in my Keychain."
    You should now see a blue share folder with the name of your Time Capsule.
    Any hard disks attached to the Time Capsule’s USB port will also appear here as blue share folders. To mount them on your desktop double-clicking their blue folders. If you had a separate password setup for those disks in Airport Utility then enter that password if asked. Otherwise, it should now mount on your desktop.
    Let us know if this solves your issue. If, however, the drive is not showing up either on the Desktop or the Sidebar, you may still need to do the following...
    *On Desktop*
    In the Finder, go to the Finder menu and select "Preferences".
    Click “General” in the toolbar.
    Ensure that all the items under "Show these items on the desktop" are checked.
    Close the preference window.
    *In Finder SideBar*
    In the Finder, go to the Finder menu and select "Preferences".
    Click “SideBar” in the toolbar.
    Ensure that all the items under "Devices" & “Shared” are checked.
    Close the preference window.
    Did this resolve the issue?
    As for Disk Utility, bear in mind that DU won't "see" network attached storage devices unless they are already mounted on the Desktop. And even then they are sometimes not "seen" by DU. If you are going to do any work on a network attached storage device avoid attempting to do it wirelessly. Best to connect it directly to the Mac (USB/Firewire), or at the very least via ethernet.
    Hope this helps. Cheers!

  • Envio 3TB Ext HDD not recognised

    Hi My External HD can no longer be recgnised by my Windows 7 64Bit computer. It as always been a bit temperamental because I couldnt start up my computer with it connected. But now it says it cant recognise it and comes up with an error 43. I have tried to reinstall drivers but it still wont work.
    I have a lot of irreplaceable info on the external HD and am really upset i cant get it to work
    Can someone help me please.

    The error 43 could appear due to different reasons and therefore its not easy to say what cause this HDD malfunction.
    The issue could be caused due to faulty driver installation, faulty USB cable or USB port.
    Its also possible that the system has been muddled up and the registry needs to be cleaned or repaired.
    From my point of few you should check some essential workarounds.
    First of all I would recommend you to connect this HDD to another computer.
    Test it using 2nd notebook or desktop PC and connect this HDD to different USB ports.
    Your computers USB ports should be checked as well. Disconnect all USB devices.
    Go to device manager and delete all USB hubs, controller and ports.
    Then reboot the system.
    After new reboot, the system should initialize the removed ports automatically.
    Last but not least Microsoft has published an troubleshooting document in order to fix the error 43 issue.
    Error: USB Device not recognized when you try to access a USB external hard drive.
    http://support.microsoft.com/kb/2654149
    Check it too.
    If nothing would help, probbaly the HDD is faulty :(

  • External HDD not recognised in Mac Book Pro

    I am trying to connect a external HDD to the MacBook Pro. The external HDD used is Seagate FreeAgent GoFlex 1 TB powered by a USB cord connected to the laptop. The light on the HDD is not glowing neither does it feel like moving when touched.
    Can somebody come back with a solution to get the HDD working on the Mac?

    By placing the HDD in a different enclosure, one would be testing if the enclosure circuitry is faulty.  Since it works on a PC, then that is not the problem.
    noondaywitch may be on the right track.  I note that your HDD has an optional Firewire connector available.  You might order that or get a 'Y' connector where there are two USB connectors that you would insert in two USB ports on your MBP thus gaining more power for the Seagate.  No guarantees of success with either option.
    Ciao.

  • ESATA HDD not recognised on cold boot, OK on reboot

    Hi, I have a HP Elitebook 8740w from which I have removed the internal HDD and connected an eSATA HDD which is powered from the USB bus (I've done this for security purposes). I'm having a problem whereby when booting at  initial power-on, a Non-System disk or disk error is encountered after the HP screen. I can then boot into Windows by pressing CTRL+ALT+DEL however having to do this each time I start up is not ideal. Also this error is not seen when rebooting, only at power on. I have tried powering the HDD from the supplied AC power pack and the problem disappears which make me think it is an issue with the USB power (either insufficient current supplied or full power is not available at start up). I have tried all combinations of USB2.0 and SuperSpeed USB ports with the supplied USB Y cable without success in removing this error. Any ideas? I would prefer to run the HDD from the USB ports to save carrying the AC power pack and because often only one power point is available. Thanks

    I think I've worked it out... I was running the laptop on mains power only with battery removed. Tried it with the battery installed and problem disappears, it must provide extra power at startup to spin up the HD. Laptop AC adaptor is 200W though, would have thought this would be enough...
