Question about Cavalry Storage CAUM3701T0 1 TB USB 2.0 Hard Drive

Open Question

Cavalry ExHD powers on but doesn't light up or connect to laptop.

Laptop Info: Windows 7, Dell Inspiron 1764 I've had a Cavalry 1TB ExHD for years and never had a problem with it. Usually only use it to put large files on for long term storage. But now when I turn it on, I can hear and feel it start up (disk is turning), but 1) the blue light that illuminates the logo doesn't appear and 2) I can't get it to connect to my laptop (never see it pop up as a connected usb device or under my computer in explorer display. Would really like some help on what the problem is and hopefully some way to fix it (or at least get it working long enough to transfer data to another ExHD if I have to get one). Thanks.

Okay , so there are some steps to figure out what is wrong with your external.

Firstly , if your computer makes a sound when you plug in your external , go to Start-Control Panel-Administrative Tools-Computer Management-Disk Management , and see if your external drive is listed here with your local drives. If it is listed , right click on the drive and change the drive letter to make it appear in "my computer".

If your drive does not make a connection sound when connecting to your computer and also does not show up , please follow the next step.

Remove the hard drive from the casing if possible and install it in your computer case or another external case.If the drive works , the problem is with the casing and you can ignore the drive.

Now , if the problem is with the casing , there are still 3 possibilities.

  1. The USB cable between the drive and the computer may be damaged.
  2. The circuit board which connects your drive to the interface of the external may be blown.
  3. The power supply (if applicable) may have a blown transformer.
The latter is the easiest to diagnose , does your external light up at all when you plug in the power? If not , then this is probably your problem. On the bottom of the adapter is a label which you will be able to use to have a new adapter made at your local electronics shop and this will cost about $30 max. They will also be able to test the adapter with a clamp meter to see if this is really the problem and this should be free.

The second component you want to test is the USB cable. If you have a printer , swop out the cables and see if your printer functions normally. Most externals use the same connector so you should be able to test it in this manner. If the cable works go on to the last step. If the cable is defective , replace it with a new one which you can find for about $10 at most electronics and chain stores.

The last component to test is the circuit board. This is a bit of a grey zone as you probably won't be able to spot the blown component unless it failed really badly. With the casing already opened , locate the external's circuit board and check to see if you have any blackened components or fluids leaking from some components. If all the other components of the external worked perfectly , then this is the faulty part. It is not really economical to replace the circuit as most of the time it is out of production by the time you need to replace it and it still costs a lot even if it is available so if your drive is working perfectly when connected via sata or IDE on your computer , the best is to buy a new casing and place your old drive in the new casing.

A casing costs about $50 and you could get it at most tech shops and big chain stores like Best Buy.

I hope this solves your problem and please reply if you need more help.

Kind Regards
Andrea

1. This could be due to several things.
a. The power supply for the external drive is not working properly
b. A broken power supply connector.
c. The USB drive was disconnected improperly > that is not disconnected safely in Windows
d. The external drive controller in the USB case is defective. A new case is needed.

The HDD is probably in working condition, however the enclosure may be damaged. You can remove the hdd inside the cavalry storage enclosure, and if you have a desktop install it in the desktop to get your data off of it. You may instead wish to purchase a new hdd enclosure which can be bought online from many websites such as http://ncix.com or newegg.com

1) Examine your "Function"/"F" keys and look for a touchpad icon. If you find one, hold the "Fn" key and press the touchpad icon button to unlock the touchpad. Move on to Step 2 if your laptop doesn't support this feature.

  • 2) Plug a USB mouse into an open port on your laptop. Click the Windows "Start" button. Click "Control Panel" in Windows XP and double-click "Device Manager." Type "Device" in the search box in Vista and Windows 7 and click "Device Manager" from the results.

    I have a Dell inspiron 5100. When I try to turn it on, it just stays blank. It shows the Dell and Windows logos, but the screen where I'm supposed to choose my user account doesn't appear.


    Are there any error messages displayed? Does the laptop switch off, or does it still remain on? (are lights etc. on?). Also, have you connected to an external monitor recently? I suggest attempting to connect to a monitor or TV using the S-Video or VGA connectors on your laptop, this should get the login screen to show up.

    It sounds to me to be a software problem and not a hardware problem. What you will want to do is go to the following dell support website and download updated QuickSet application.

    The link is http://support.dell.com/support/downloads/driverslist.aspx?os=W764&catid=-1&dateid=-1&impid=-1&osl=EN&typeid=-1&formatid=-1&servicetag=&SystemID=STUDIO1737&hidos=WLH&hidlang=en&TabIndex=&scanSupported=True&scanConsent=False

    You may also want to check and see what version of Bios you have and update. They release a new version last month.

    Thanks and hope this helps.

    Hey Jeff,
    Sounds like this is something with info you need to keep..Keeping/securing/BACKING UP your data is your priority!! Personally, I would find a QUALITY (ASK a lot of questions.. can they guarantee their work,,- and NOT LOSE your data..!!) .. skip the geek squad - .. computer repair shop..(or some 10 year old).. I would first see if they could copy this drive to another drive (solid state) so you will not lose your data... we are at 4.0 with USB now... 2.0 is becoming the "floppy" of today..I have 3.0 drives and feel left out.. again.. securing/copying/backing up your data is paramount.. Good luck,,,
