My External Harddisk 320 gb transcend not detected by my usb port while that same port is working fine for other usb devices same usb harddisk is detected on the laptop

I HAVE THESAME PROBLEM WITH Transcend StoreJet 2.5 120 GB USB 2.0 Hard Drive ON MY VISTA 7..WHY THERE ARE no any hints or answers here ? so we can get help? thanks

if your computer came with a motherboard disc the drivers could be on it
click start control panel administrive tools ,computer management ,device manager look through all of your devices if you see a yellow question mark?or exclamation mark ! or red x
right click to reinstall drivers or
if you can see your usb but its not working
ports(com&lpt)right click update driver
just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again, sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable,
check the USB leads that attach to the motherboard usually red-white-green-black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems
hope this helps

hello

connect the USB external hard disk to usb port by the way disconnect other working harddisks
available on the system, boot the system with bootable cd/floppy go to command prompt and run
chkdsk on this drive

Also download "mbrfix" connect all working harddisks along with the nondetecting harddisk and run mbrfix for the USB defective harddisk

Try using different USB data transfer cable, if power source adapter is used check for rated power output in multimeter for this adapter, if found defective replace it with new/good adapter with same
specifications

Bad luck if harddisk controller has failed you have to go in for new harddisk

GOOD LUCK ooo

bad cord

Good day!

1. Go to my computer and right click then click manage, go to disk management and see if your external harddisk is showed.If showed,then you can see the options there to manipulate your harddisk, either you format it or repartition.
2. You can use also a disk manager software to fully control the function.

The problem is the usb ports in your pc. You know the drive works and is properlly deteced on the laptop so you can ignore that.

IF you can try other usb devices in your pc usb ports and see if they work.If they don't at all then you either have dead ports or drivers are missing. You should see them listed under control panel system hardware.

If they work then I would wonder if the usb drive you have requires a differant usb port than what you have. There is a type 1 and 2 and type 3 which has just come out so we can ignore that one. A type 1 is slower and cannot power devices usually. A type 2 is faster and can power some devices. I don't know how old your pc is so it could be hardware, either failure or drives. You should also makre sure you have the service packs installed for windows. Sp3 is the latest version. There were some changes to the way usb devices were deteced in Sp2 if I remember correctly.

some people say that its because of not enough power . try inserting the hard disk in other usb slots ( at the back ). onlu usb slots at the back of my pc detects my hard disk

same problem
