3TB Hard Drives Coming, but You’ll need a new Computer

Hard drive manufacturer Seagate has confirmed to UK website Thinq that 3TB hard drives are definitely on the plan for 2010.

The only problem? If you’re using a 32-bit version of a Windows operating system (which is – most people), you may end up seeing as little as 990MB of that huge storage capacity because of limitations to the Logical Block Addressing (LBA) measures used to access the space. Current PC standard for LBA cannot address more than 2.1TB of storage in a single drive.

The limitation appears set to become the "Y2K problem" for hard drives with the limitation of the LBA system setup by Microsoft and IBM back in 1980. Apparently, no-one expected anyone to need more than 2.1TB of storage.

Seagate product manager Barbara Craig told Thinq support for Long LBA is required for both hardware and software to handle the new drives which limits operating system support to 64-bit Windows 7 and Vista plus modified versions of Linux. The new 3TB drive won’t work with Windows XP at all.

The problem with hardware is more difficult to fix.

Drives of greater than 2.1TB will also require a GUID Partition Table – a system implemented in Apple computers – because the old Master Boot Record (MBR) method of noting storage particulars again can’t work with drives greater than 2.1TB. Intel announced last year that it was looking to improve the old DOS-look BIOS system with EFI – Extensible Firmware Interface.

However, very few PC motherboards currently support EFI and that pretty much knocks things on the head right there in terms of upgrading.

So if you’re thinking about turning your PC into a storage farm, chances are you’re going to need to start from scratch with a new PC to go with it.

How to restore the disabled startup programs

This post provide further information about How to restore the disabled startup programs after an upgrade from Windows 98 or Windows Millennium Edition to Windows XP. After you upgrade your computer from Microsoft Windows 98 or Microsoft Windows Millennium to Windows XP, the programs that previously loaded during the startup process may not be listed in the notification area (the system tray), and they no longer start automatically when you start your computer.

This behavior can occur if Windows XP removes all of the program files (all of the .lnk and .exe files) from the Startup menu and the Run key in the registry, except for the "known good programs," which are not removed. You can observe this behavior after Setup is complete and you have logged on to your computer for the first time. The files and values are moved to a hidden folder and registry key. Then, the Microsoft System Configuration Utility (Msconfig.exe) is populated with the Startup tab information.


To Fix windows Operating System issue, reinstall the values to the registry and the programs from the Startup folders:

1. Click Start, click Run, type msconfig, and then click OK.
2. Click the Startup tab.
3. Click the Restore Startup Programs option.
4. Select the programs that you want to restore, and then click OK.
5. Restart the computer.

NOTE: This option is not available if Windows XP Setup did not disable any programs from loading during the startup process.

How to remove unsigned drivers

All the drivers that are included with Windows XP use digital signatures to verify that they have been tested by the Windows Hardware Quality Labs (WHQL). Many third-party programs are written for Windows XP must install additional drivers that have not been tested by WHQL. Therefore, they do not receive a digital signature.

Note Some third-party vendors have tools that they can use to generate a valid digital signature even if these products were not tested by WHQL. The following procedure cannot be used to determine whether these drivers are installed.

Windows XP includes the File Signature Verification tool (Sigverif.exe). You can use this tool to find all files on your computer that are not digitally signed. For the purposes of Windows XP clean-boot troubleshooting, you have to test only the files in the %Windir%\System32\Drivers folder.

To use the Sigverif.exe tool, follow these steps:

1. Click Start, click Run, type sigverif in the Open box, and then click OK.
2. Click Advanced, click Look for other files that are not digitally signed, click Browse, locate the Windows\System32\Drivers folder, and then click OK two times.
3. Click Start.

After Sigverif.exe is completed, a list of all unsigned drivers that are installed on your computer appears. Above given tips if creating any problems to unsigned driver contact to operating system support technician
