Is it possible to search for a specific file that was saved on my toshiba canvio hard drive?


Use this USB Y-Cable.f014c47.jpg It provides the extra power you need for your external Hard Disk Drive or other USB devices when a standard USB cable is not able to transfer enough power to operate your device. Simply plug the mini-B cable into your USB A ends into open USB ports on your PC. The cable draws power from both USB ports and increases the output to the external Hard Drive or USB device.
Clue of step are listed below: 8376d83.jpg

Click All files and folders There it will display you in this formatad8764d.jpg type the name of the file or a document that you are wanted to search. And choose the option that you wanted to perform.480a4b6.jpgClick Search and see.

Computer not recognizing external Hard Drive


Aren't usb drives fun? Anyway, there are a few points where this can break down. Your external drive is actually made up of a few parts. It has a normal hard drive, and either what is called a "SATA to USB Bridge" or a "IDE to USB Bridge". If it is a full desktop size hard drive, it will come with a power supply that you plug into the back of the drive. If you have a laptop hard drive it can be powered through the usb port.

When you plug it in, the computer should recognize that you plugged in a new device and show you a message saying found new hardware, found usb to ata bridge, found disk drive etc. in that order. If you get these messages and still no hard drive shows up in my computer, then you may need to assign a letter to the drive or even format it. Right click on the "My Computer" icon, then select "Manage". On the right hand side of the window that appeared, double click storage, then disk management. It should list all drives attached to the computer. Your TB drive should show up as a removable disk, and should already have a partition. If it does not have a partition, you will have to partition it. Just right click on the rectangular part (on the right side) and select format. If you cant format it, try right clicking on the left hand side, the square bit, and select initialize. Then format.

If you just need to set a drive letter, right click on the rectangular part and select 'change drive letters and paths"

Here are some other things that can go wrong:

Not enough power, the drive isn't getting enough power and cant mount. Try plugging in the power adapter that came with it or try a different usb port. If it came with one of those funny looking Y shaped usb cables, plug both ends into the computer, so that it can get enough power.

Bad hardware, either the hard drive or the bridge is bad.

Then you need to return it to the store you got it from. If that is not possible you may be able to pull the drive out of the enclosure and use it as an internal drive.

Bad USB ports.

This can be hardware or software. If other usb devices work fine then this is probably not the case.

Vista does not recognize my dynex external


Try this fix for missing usb ports by

Create a file with NOTEPAD containing the following lines and save it as FIX.REG
-------------------------- Use text after this line --------------------------------
REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"
-------------------------- Use text before this line --------------------------------

Double click on FIX.REG and say yes to the Merge Into Registry question.

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Disk Drives that you know are not present.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

Comstar USB Drive disconnect and reconnects Plugged into usb port on Xp service pack 2


I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems (mac/ Linux) similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especially true if you move a HUB to another port

If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.

Any exclamation marks by hardware need fixing before you investigate any further

USB flash drives can fail for no apparent reason.
Sandisk Cruzers are especially bad for this.

USB hard drives should be treated with extreme care.
This is a real hard drive ! and knocks and bumps can quite literally kill them.

It is possible to remove drives from the enclosures in most cases and connect directly inside a PC to fully check it.

Note that if you hear a drive clicking or pinging this could be the worst thing you would hear.

USB issues with Dell PC


I think you answered your own question.

Yes its true that many pc's dont proide enough juice to the ports.

This is even more noticable if you have lots of heavy drain usb devices. small external hard drives are esp bad in this area and if you are unlucky enough to own a "USB powered" printer these too can have adverse effects on usb performance.

I have a 320 Western Digital external drive. It works fine if I plug it directly into the computer usb drive. HOwever, I want to use it thru a hub cause it is difficult to get to the back of my computer. ...


Does your External drive have a seperate power supply? Or does it get its power through the USB port.

If it gets its power from the USB port then by adding a hub you are essentially dividing the amount of power supplied by the number of ports extended.

One possible solution that could solve that situation would be to get what is called a powered hub. Which is exactly as the name suggests. The Hub has an external power supply so that it can provide even power to all of the ports.

I hope this helps
If not please post an update and I can try to find a better solution
If you need more help please post what Model of WD ext drive you have (ie....My book, Elements, Passport etc...)

Thanks,
Dave

Hard drive i not recognized - and clicks


Is this an external hard disk?  If it is it probably indicates that it cannot get enough power from the USB.  You need an external power source.  use wither a second USB port or a plug in poer supply.

USB malfunction


Hello jaybear

The most likely problem is your USB bus is underpowered for supporting your external hard disk drive along with other USB devices.

First, this is actually a good thing in a way. The reason is, it is actually telling you right up front that your USB bus is underpowered for this device. That's a huge improvement over issues caused by underpowered USB buses in the previous model computers. In those, we were left to having to figure out what the problem was when a USB device inexplicably stopped or didn't work.

What is happening is, your new hard disk drive(s) (HDD) are trying to run off of power supplied by your computer's USB "bus" (circuitry). This is OK for USB devices needing low power. But in the case of external hard disks, it's "iffy" whether there'll be enough power on the USB bus to support even one of them, much less two or more. Particularly on laptop computers.
Have no fear. This problem is easily remedied. :)

You need only attach an A/C adapter to each of your external hard disk drives and you should be OK.

If that is not an option, connect a **powered** USB hub to your laptop and plug the external HDDs into the hub instead.

By "powered" I mean a USB hub that comes w/ an A/C adapter. In either case, using a powered USB hub or attaching an A/C adapter to your hard disk drives will remove the external hard disks' power load from your laptop's USB bus and provide sufficient power for the HDDs to run.

You can find USB hubs at Newegg.com and lots of other online high tech stores. I like Newegg because their prices are competitive, their customer service is excellent and there're customer reviews of most of their products there as well.

If you have any more questions, comments, observations - anything at all, just let us know. We're here to help.

Otherwise, PLEASE, take a moment to rate the solution that best addresses your problem. If the solution provides a "fix" for your problem, then a **FIXYA** rating would be very much appreciated. :)

Thank you

Hi,
If this is an External USB Hard-Drive, your problem is insufficient power provided by the USB Port.
1:- Try Another USB Port If You Have One.
2:- If you have a 2 into 1 USB Cable, connect 2 into 2 individual USB Ports ( On Computer ) And 1 into Hard-drive Unit.
If none of this works, your drive is faulty.
