Re: ext.hdd can't be detected..

When you have the drive connected,go to your control panel,open up Administrative tools,Computer Management,Disk Management.See if drive is there.If it is, right click in drive space ,assign a drive letter.
If not,scan for new hardware.
You could also look at your usb port handler in your device manager.Update your usb controller,usb handler

My computer don't see mt toshiba 500 GB external disk. I had Win XP with SP3 and my external disk is connected to a USB hub with 8 ports. I had a pen connected to that hub and the computer see it. But...

Your USB hub cannot provide enough power for your external hdd, you can try to plug it in directly to any free USB port for the mean time to check if its detected or not, if it has a power button ( which is not normal for regular USB powered EXT HDD) make sure that it is on, if its still not working try to use a different cable, a known good cable or plug it in to a different computer to check if its your USB port, or the usb cable or the ext hdd that is causing the issue

Hope this help.

Hi. My computer says I ejected my WD My Passport external drive but it was not properly ejected. How can I fix this. I need all my thesis files but computer can read the external drive! Help please!

Try to test your WD Ext HDD to a different computer and check if you will get the same problem.

If the same problem persist try to use a different cable for your WD Ext HDD.

If still fails kindly ask the store where you bought the WD Ext HDD on how to retrieve your files and have WD EXT HDD replaced?

If your WD Ext HDD works to a different computer then update the BIOS and Chipset of the computer where your WD Ext HDD connected previously.

Hope this helps.

I am using Transcend 320 GB external hard disk in a Windows 7 Operating system. It is keep on asking me to format the disk while i plugging in to laptop. Unable to see the contents in the external hard...

guess you are using a USB port to for that.....
1 - check the cable that connects the HD to the USB port...change the cable and verify
2 - connect to another PC and check if it's ok there
3 - bring another ext HD from a friend and try conencting that....check if that's OK
4 - there could be a corruption in the HD that is preventing the PC from reading it

cardinal rule for USB....not a very dependent device specialy if connecting thru USB data cables....
always use a good qty USB data cable compatible with some cheap cables are only for USB1

My WD My Book Essential 1TB External is not showing up on 'My Computer'. It was working perfectly in the morning, then when I rebooted my machine it no longer showed up.

disconnect your WD ext HDD. and reboot your computer. then connect again. if still not showing. go to device manager (right click my computer then properties -- click device manager). expand by clickin "Disk drives" category here it will show all the hard drives installed in your computer including your WD ext HDD . if you see yellow sign on your external drive right click and remove then go to Action menu click on Scan for hardware. it should detect and install the driver again. if still the same or maybe its not on the list of Disk drives.. try to change another USB cable .. i hope this will help

HDD Problem

The info is not clear as to if it is a desktop or laptop . However what u could try is reseating the hdd and also get into BIOS by tapping F2 and u would find a option to restore defaults, after restoring check if the hdd is getting detected . Also make sure that external peripheral like Ext hdd and other usb devices are disconnected. Update once u have tried this.

External hard drive won't connect to computer

first of all you should try it on deferent pc , if its ok then thatleads us to insufficient power provided through usb ports , try usingback usb ports not the ON-front, and if the problem still try usingdual-usb cable like this if the external hdd doesn't work at all it might be the usb controller board inside the hdd cage needs to be changedif you cant find a similar one you may buy a new empty cage

Dear Sir,

Here is the Procedure for Connecting External Drives to Computer.Several brands of computer does not recognise external drives when connected to USB expansion slots,and Slots of front panel,So connect your Ext HDD to back side onboard Slots.Because there is a lack off USB power surge voltage to detect a large capacity exteral drives.Some time it is does not recognise by many computers,when USB power surge voltage is low.

Windows XP stopped recongizing eGo external Hard Drive I just installed a new iomega eGo 1 TB desktop Hard Drive yesterday, got the bugs worked out and my Dell w Windows Xp seemed to recognize it, Today,...

2 things... the USB port is bad, or the USB cable is too long and the HDD isn't getting a good signal.

1. Try another port and see if that works

2. Nip over to WalMart, Circuit City, Micro Center, PC World or Best Buy and get a shorter, Thicker USB cable of the same type - a cable which can provide the signal strength your ext HDD requires.

Also a possibility... The HDD may be 'lost' as Win cannot accept one of that size or the label/signature fell off and it is an orphan. It MUST have a driveletter, and it MUST have a special WIN signature byte on the HDD for it to work.

Bootup as normal, let everything get quiet, then plug in the ext HDD

Rt Click My Computer, Manage, Device Manager and in the Rt side, highlight the TOP icon. Then under Help, click the Computer with magnifying glass icon and wait. This forces your OS to 'Look' for any new devices.

When it finishes looking, look again under My Computer to see if your new HDD is now there. It will have to be formatted and have a driveletter for this part to work. Jump down to Disk Manager and see if it is there. You may have to Rt. Click and import it as a foreign drive or Rt click and give it a Driveletter ;-) If it is not, use a shorter, thicker (more wires) USB cable and try again.

Windows doesn't like Any HDD without win signatures on them - aka:'foreign disks' so ANY time this happens, if OS doesn't see it, use disk manager and Import it, then Rt click it and give it a Diskletter.
