try other usb port, or other computer and see whether the hdd is detected. If still not, try to go to device manager ( http://www.computerhope.com/issues/ch000833.htm ), and then assign a drive letter to the hdd. After that, try to access it from Computer, if not able to access it, format it (use quick format) and then use this program to recover your files. http://www.asoftech.com/adr/
If the drive is not seen there, check under Universal Serial Bus Controllers (if the drive is connected via USB). The drive should appear as a USB Mass Storage Device.
If a yellow ! icon is displayed next to it, double-click on the drive.
A Properties window will appear and will probably say "This device is not working properly" and will give either (Code 28) or (Code 10).
If Code 10 appears, the drive has most probably failed. Verify by trying the drive with another USB cable or port, or on another computer. If the drive does not work on the 2nd computer, the drive is probably defective. You can begin a replacement request at our Warranty Services Page.
If Code 28 appears, you will need to test the drive on another computer.
If the drive functions correctly on another computer, the Windows USB drivers are corrupted or missing. You will need to try to reload the USB drivers for the operating system by inserting your Windows install CD, rebooting, and attempting a Repair/Restore. This can be dangerous to your data and you should disconnect your external drive before attempting this. If the drive does not function correctly on the 2nd computer, it is probably defective. You can begin a warranty replacement at our Warranty Services Page.
For Vista and Windows 7 Only: If the drive works fine on another computer, there are a few steps to follow while the drive is connected to the original computer:
Right-click on Computer and choose Manage.
Double-click on the Device Manager.
The device will usually appear under "Other Devices" or "Unknown Devices"; right-click on it and choose Uninstall.
Once it has disappeared from the Device Manager, disconnect the device.
Open a Windows Explorer window (right-click on Start > Explore).
In the address bar, type c:windowsinf and press Enter. For Windows 7 type c:windowssystem32driverstore and press Enter.
Delete the file INFCACHE.1.
If you get an error when trying to delete this file, try the following steps:
Right-click on INFCACHE.1.
Click on the Security tab.
Click Edit to edit permissions.
Click Add to add Group or User name.
Click on the user name under which you are currently logged in.
Click on the Full Control box in the lower permissions section, then click OK.
Delete the file.
Reboot and reconnect the drive. The file should be rebuilt, correcting the problem.
If that fails, you will need to try to reload the USB drivers for the operating system by inserting your Vista install CD, rebooting, and attempting a Repair/Restore. This can be dangerous to your data and you should disconnect your external drive before attempting this.
yah you must buy a Y-USB cable for your external hardisk. this is connection both ends are one is for hardisk and the other two cable is for USB slot of computer. why it two wires connection to usb because one wire is for Data and the other is for Power. If doesn't work..it might be a problem in your Operating system. i recommend to you to reinstall your Windows OS.. theres a 4 reasons why it happen appear the error... deffective USB cable..corrupted driver of USB device for seagate, virus infected of your systems..and maybe your hardive is deffective. Please rate if this is HELPFUL..thanks
Check the partition size in Disk Management (if running Win7 - download a free Partition Manager if not) and see if the system is seeing the partition correctly. Seagate has recovery software available on their website but you may just have to repartition and reformat.
Let the system to search for drivers automatically. Before proceeding that place any driver cd into the CD drive if came along with your ext. harddisk so that the drivers from CD will be automatically taken by the driver installer. Thanks
u can try some hit and trial...
1 - keep ur USB HD off and switch on the PC then switch on the power on USB HD
2 - try another USB port
3 - try another USB cable connector
4 - check ur Device manager/usb root hub settings/power setting, uncheck the box that says" alow computer to switch off power....in Power Mgt tab
I've similar problem with Samantha_500, i inadvertently dropped internal Harddisk (Seagate 80GB) with external case (M-Tech), the external case was broken into pieces (only the parts with plastic), the Harddisk is not working anymore, it detects by windows XP as a device connected in USB, but no drives detected in windows explorer. is there any way to recover this harddisk? thanks for the help in advance.
I assume Seagate suggested you "reinstall" the drivers. If that's the case, you may still need to refresh your computer's device list to properly identify the drive.
If you're running Windows you may try opening "Device Manager" and uninstalling the device from the list, then "detect hardware changes". This may make your computer redetect the drive like it's a new device, but may not.
I suggest phoning Seagate back and ask to talk to a knowledgable tech, not the scripted phoners.
