Windows 7 64bit doesn't recognize the USB External HDD Stor E art 3.5"

I purchase the External HDD Stor E art 3.5" and pass a few days the windows don't recognize the HDD. Try to connect the drive to other 2 USB ports and nothing happen. Use a USB pen drive to see if was a problem with the USB ports but all 3 are OK. Try it on the Asus notebook and windows 7 recognize the HDD. I formated the HDD in FS NTFS. In the disk managment don't show the external HDD. What can I do to resolve this problem?
My notebook is a Qosmio F60

One last thing you can do about that.
Install OS again using original Toshiba recovery image. After doing this you will have clean preinstalled OS and everything should work well again.
If the same will happen again you should contact nearest Toshiba service and try to clarify the situation.
I know it is pretty radical solution but, believe me, most effective to check notebook functionality.

My new 24in imac doesn't recognize my usb external hard drive- snow leopard

i was attempting to do a new time machine back up on my new mac but it won't recognize the usb external hard drive (kaser 250gb). i used it frequently on my old g5 imac, no problems. i plugged the hard drive into my g4 ibook and it recognized it right away. i followed the apple tip of pulling the power plug out of the wall power socket and pulled all the usb cables out as well (i have the wireless keyboard). i let it rest for over 5 minutes and only plugged in my wacom stylus and usb external hard drive. still nothing. and it doesn't show either in disk utility. i also downloaded as per another thread the 3g ntfs system preference but to no avail. the only thing i can of doing is erase and reformat my external on my ibook, but i don't want to risk loosing the data without a back up.
anything else i can try? (before i buy time capsule) thanks

i just checked again by plugging the external into my ibook g4 and checked how it was formatted - mac os extended (journaled).
Then the 3GFS software is not required at all.
i have an idea, not sure if it will work and it will have to wait a couple days until i get my firewire back from a friend, but this is what i'm thinking: my intel imac has a 1tb hard drive. could i use target mode between my imac and ibook? with my ibook i'd attach the external hard drive, then using the firewire and target mode start it up. hoping that the ibook hard drive and the attached external hard drive would show on my intel mac for which i could copy over the external back ups onto my imac. once completed, i could erase and reformat the external on my ibook and then try again on my imac to see if it appears on my desktop. do you think this might work (even though it is correctly formatted already?)
I use Target mode on a regular basis for mounting the internal drive on a Mac to transfer or salvage data. I don't know if you will be able to connect to an external drive on the Target computer. There's not usually any reason for this and I don't know if the Target Mode will enable the Logic board to deal with the USB ports and transfer data. I kinda doubt it, but other more experienced users can jump in here.
I don't think the problem with your external drive is the format, since you've already checked it and it is already formatted for a Mac. Intel Mac's will mount drives formatted by a PPC Mac with no problems, unless your OS doesn't support the chipset in the USB case that connects to the drive. There are some USB drives that are known to not work well with SL but worked fine with Leopard.
You can buy a cheap USB case (about $30) and move the drive from the old case to the new case, or buy a USB to IDE adaptor cable (about $20), or you can buy a larger external drive that will work on the iMac and use the G4 to transfer the date from the old drive to a new one. Or you can take both drives to a friend with a Mac and use Disk Utility to restore the USB drive to a partition on the Firewire drive. That doesn't fix the USB drive to work with your new Mac, but unless the vendor comes out with a firmware fix, I think that's a lost cause anyway.
other than the above, i may just go buy a 1tb time capsule,
I would not be getting a Time Capsule to back up a single computer. Wireless backups are a lot slower than FireWire or USB (of course, it's the initial backup that takes so much time). If you do have several Mac's that need a TM backup volume, then the Capsule can help you out. It is supported by Apple (and there are a lot of users here in the forums). I'm using a ReadyNAS device for network backups, but it is not supported by Apple, and I have to rely on NetGear for fixes if an OS update breaks my backup system.
BTW, it's a good chance that a TC device will be able to see and mount your USB drive. The incompatible chipset problem with some drives seems to be limited to the USB drivers in SL which the TC is not running. That's why I said that a USB hub may also let you see your drive, the problem is there's no guarantee's...

I just opened my new Mac Pro and I have a USB keyboard, not a bluetooth -- it doesn't recognize the USB keyboard and I can't get past the "bluetooth keyboard pairing" screen.

What specific KB?
Do you know it works?
I set my 2103 nMP with an older (black) Apple USB KB and it worked fine

Equium A60 doesn't recognize the USB webcam

i have just bought a creative vista plus webcam and tried to install it on my Equium A60 laptop, the software installed fine and everything but when i plugged the webcam into the usb port my laptop didn't recognise it.
i tried uninstalling and reinstalling and nothing changed. Anyone have any idea what might be wrong?

Hi, kirsten_uk when you connected your webcam into the USB port for the first time did Windows prompt you to install drives?? If not then something has gone wrong with the driver installation or the camera is defected.
Run Control Panel, System and locate something called "Device Manager", (run this) and look for yellow markers over the USB section. If you see a yellow marker this indicates Windows doesn't have a driver for the device, the problem can be corrected by forcing the re-installation of the drivers.
If still no joy, I would recommend trying another USB port or another computer if that fails the cam is defected.

My HP Pavillion w/Windows XP will not recognize my new External HDD

HP Pavillion w/Windows XP Media Center m7267c Desktop PC
Is it necessary to pay a outside Driver manager to restor the ability of my PC to instal Driver Software for devices that the specific Mfg states should already have present on my OS?
I purchased a Western Digital 2TB External Drive ( WDBAAUOO20HBK-01 ) to free up my packed Internal HDD. I made sure it was a "USB 2.0" device. But the PC will not recognize the external HDD device.
Please help if you can

BTW...the Drivers that are supposed to work are :
c:\\windows\system.32\DRIVERS\disk.sys
c:\\windows\system.32\drivers\partmgr.sys
....at least those are the Windows drivers that are loaded off my newer Dell PC when the Ext. HDD is plugged into it.

Windows PC doesn't recognize iPod

I have bought my iPod (20GB, click wheel) one year ago with an extended warranty of 3 years. It was working well all the time. But now my Windows computer doesn't recognize the iPod any more although I haven't changed anything on it.
The battery can still be charged using the docking station. But as soon as I plug in the iPod on my laptop USB port the iPod freezes. The only message on my laptop screen says that the external hardware can not be recognized.
The USB port is working properly.
I have also tried to install the iPod update and to reset the iPod. Nothing is working. I guess I can't restore the iPod since it's not even recognized.
Thanks, Annemarie

I thought I was alone with this problem. I recently went traveling last weekend, and began to think the X-Ray machines killed my iPod!
Whenever I connect my iPod to any computer using the USB connection, Windows will not mount it as a removable drive. The cable is good, because the iPod is being charged but Windows will not recognize it.
I have tried all the different USB ports, even on several different computers. Including my work, laptop, and my desktop. Windows will not recognize my iPod using the USB connection.
I'm in the process of restoring my desktop computer after a hard-drive failure (lucky me all my vital data were on a separate drive), so my desktop has a nice clean install of Windows.
My desktop has a firewire port, so I tried connecting to that port and Ta-Da, Windows recognized and mounted my iPod as a removable drive! Unfortunately my laptop nor my work computers do not have firewire ports.
Can anyone explain why the USB function suddenly stopped working? Does this mean I need to restore and loose all my music from my iPod? I do not let iTunes manage my music, I do that all myself. I can put my music back onto the device but it will be time consuming. If anyone knows the answer to this USB problem, perhaps you can reply to this thread or contact me.
Thanks,
Joe Vill

Media Encoder doesn't recognize Behringer USB mixer

I just purchased a Behringer Xenyx X1222USB mixer to use for live stream events using Flash Live Encoder on my MacBook Pro. Flash Encoder doesn't recognize the USB input from the mixer. Other I know the computer recognizes it since I went into the Audio Settings and can see the USB input there with audio levels.
I use Yosemite platform. Any help needed as soon as possible.

So, it looks like Media Encoder is stuck in a trial version? The only formats available are indeed .f4v, .flv, .mp3 & h.264. Is a reinstall of Media Encoder the fix?

Trying to update firmware on my canon printer MG5320 but in doesn't recognize the printer being plugged in via USB cable

I am trying to update firmware on my canon printer MG5320 to be able to use the airprint feature but in doesn't recognize the printer being plugged in via USB cable. I have tried restarting the macbook, turning on and off the printer, repairing permissions, deleting and redownloading the update what else can I do? The prinyrt works fine otherwise...

If there are no drivers for Yosemite you might be in trouble.. HP will tend not to support printers once they are EOL.
Getting it running over wireless rather than USB might be worthwhile.
Can’t connect wirelessly HP Photosmart C4780 to MacBook Pro OSX 10.8.2 Mountain Lion.
Has the printer been working and now failed after update.. what update caused the failure if that is the problem??

Installation of Windows 7 via USB External HDD (Boot Camp Assistant)

How do I mount Windows 7 Ultimate disk image (.iso) onto my USB external HDD so that I can boot using that USB external HDD? I have tried reEFIt, but it doesn't work for me. It may be because I did something wrong. I would appreciate a comprehensive guide. Thanks.

i suspect you haven't prepared the USB drive as a boot volume.
You can absolutely do this. It is detailed on CNET in the following article: http://reviews.cnet.com/8301-31012_7-20020513-10355804.html
