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

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 Hardisk Maxtor 4 One Touch not detected

Have you tried different USB cables with the drive? If the drive is self powered (no ext power supply) which I think that one is, then it needs a really good cable to draw the 5 volts from the USB port. If you have tried a known working cable, then it could be the USB controller or the disk itself. You can buy the USB box on eBay really cheap and move the drive over.

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.
