Some tips to get info back from corrupted CD/DVD disk..
-Try recovery in a CD/DVD writer as opposed to a reader. Writers are generally more precise and can see the tracks better.
-If possible try recovery on the same drive that was used to create
the disc. Chances of a good read have been found to increase if you
use the same drive or at least the same manufacturer.
-If nothing helps you can go to music stores and show them your disc.
Such stores usually have a CD refinishing machine and may be able to do a better job.
-As soon as any of the above methods works, don't think even twice and just create another copy of the disc.
-Buy good quality media.
-Take good care of your CDs

Some toothpast and a cloth will remove some scratches

it may be the laser in your cd drive - they degrade and dust up over time so try in someone elses cd drive.

you can buy a professional cd abraser but you would be better off with a hand drill with a buffing pad and toothpaste or other abrasive like metal polish

UNMOUNTABLE BOOT VOLUME ERROR ON GATEWAY GM5045E WITHOUT RECOVERY OR WINDOWS XP DISC.


An unmountable boot volume error suggests that you may have a hard disk failure or at least some corruption to the hard disk which the system uses to boot Windows XP.
To try to resolve this problem you would need to use a specialist boot CD to try to repair the disk errors. One such disk is Hiren's Boot CD which can be downloaded as a CD image file (.ISO) then would need to be burnt on to a blank CD then the computer booted from this CD.
On the initial Hiren's boot menu, select DOS programs, then select Disk tools before selecting HDAT2 to perform the disk repair actions.
HDAT2 can take some time to complete depending on the size of your internal disk drive and the number of bad sectors or other errors encountered - the tool will attempt to repair bad sectors by reading, verifying, writing and re-reading / verifying the data.
If the disk can be recovered, then you may be lucky and the system will be able to boot but otherwise, you may still need to do some further recovery work for the operating system, in which case you may need a Windows install CD or other recovery CD media.

If HDAT2 finds a lot of unrecoverable errors then you should seriously consider replacing the drive - you should be able to recover data from the old drive using other tools on the Hiren's Boot CD, including booting the CD mini-XP environment and using the tools there too.

Tip

Disk drive may be failing or my disk won't boot


Many times before a hard drive goes completely bad there are tell tale signs. If you can recognize them, there is a good chance that the data on the drive can be saved. The window of time in which action will be useful is quite small. Other than trying to fix the problem do not use the failing computer disk as you can just make the problem worse. <br /> What are the signs to look out for? While there are few surefire signs of impending disk failure there are some warning signals that give us the hint. Watch out for: disappearing files, very long wait while accessing files, files/folders whose contents appear to be strangely scrambled, reoccurring error messages while moving/copying/deleting/creating files, and strange but frequent crashes of your OS. If your computer will not boot saying that it cannot find the boot disk or other messages similar, the boot sector may be corrupt. <br /> Another telltale sign is any loud, low, irregular, clicking, or grinding sound which is emitted from the drive. This is the worst problem as your data and the disk are almost gone. <br /> What to do? Download on a friends computer and create a bootable CD from one of these manufactures:<a href="http://www.seagate.com/ww/v/index.jsp?locale=en-US&name=seatooldreg&vgnextoid=480bd20cacdec010VgnVCM100000dd04090aRCRD"> Seatools</a> from Seagate,<span> the <span><a href="http://support.wdc.com/download/dlg/Diag504fCD.iso">Data Lifeguard tools</a></span> from Western Digital or <a href="http://www.hitachigst.com/support/downloads/">Drive Fitness Tool</a> from Hitachi.</span> <br /> <ul> <li>You must use a CD burning program (such as Nero Burning Rom or EZ-CD Creator) to burn a CD from the .ISO image.</li></ul> <br /> Using the CD, boot the problem system. Make sure the BIOS is set to boot from the CD drive first, not the hard disk. Follow the manufactures instructions to test your disk. Do not let the program write all zeros to the disk or format the disk as you will loose all your data. <br /> With luck, the program will repair any corrupt indexes. <br /> Remove the CD and attempt to do a normal boot. If you can then boot into your desktop, immediately backup any data as the fix may be short lived. <br /> If you don't have a CD drive, then you'll need to try using a bootable USB which is another topic.

My software will n ot load on to my computer


It is possible that Cd Rom drive is not functioning correctly. Do you have a second system you can test the Cd on to verify if it is the CD or your CD Rom drive that is bad.

If this doesn't resolve the issue I have 2 other ideas. :
1. have you run out of disk space? Go to My Computer and check. If you are under 1 GB of free space, try doing a clean up of your system with Disk Cleanup. To open Disk Cleanup click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup.

2. Windows is corrupted and you need to try either a repair install or a fresh install.
To repair windows corrupt files you need to have a system utility software RegInOut

It won't turn on. It shows a black screen with "disk read error occured, press CTRL ALT DEL to restart. Then when you do this it does nothing.


Make sure you don't have any bootable CD/DVDs in it. Disconnect any external USB flash/thumb/hard drives.

If that does not work it is your primary hard drive. Either the data on it got corrupted, the drive is failing or has failed.

The first step is to try to repair Windows. Below is a decent tutorial but you can find more with a web search.

If Windows repair cannot find the hard drive the it has failed. You need to install a new hard drive and hope you have backup.

If Windows repair is buggy and gives you errors of missing data during and after the repair the disk is failing and "forgetting" data. Replace the disk.

Otherwise, repair will fix things so the only thing you need to do is scan for a virus or find the program that corrupted Windows.

Good Luck!

Computer does not recognize it as a CD RW drive


When you try to write data to an optical disc, you may experience any of the following symptoms:

* You receive various disc write error messages.
* You experience issues with the drive and the built-in recording feature of Windows XP.
* You experience issues with third-party programs that you use to write data to the disc.
* You cannot read the disc in all versions of Windows.
* You cannot read the disc, or some files on the disk, by using an MP3 player.
* When you add files or folders to a disc that already contains data, some files are lost.
* Recording files to the disc is inconsistent.
* The disc recording operation is consistently unsuccessful.

TROUBLESHOOTING

Troubleshooting specific errors
If you experience one of the following errors, follow the appropriate steps to resolve the error.

* There is no disc in the drive. Please insert a writable CD into drive.
This error can occur if the CD-R drive or CD-RW drive is not recognized as a recordable device. This error can also occur if the device driver has been corrupted. To resolve this issue, see Method 3 in the "General troubleshooting" section and Method 1 in the "Advanced troubleshooting" section.

* Drive not accessible, incorrect function
This error message typically occurs when you try to write to a CD-R or a CD-RW, and the Windows XP built-in disc recording feature does not recognize the CD drive as a recordable drive. This error message may also occur if specific third-party programs are installed. For more information about how to troubleshoot this error,

when you access the CD-ROM drive, the DVD-ROM drive, or the CD-RW drive
* Error Deleting File or Folder.
Cannot delete file name. Files on this CD-ROM drive are read-only. You cannot copy or move files over to this CD-ROM drive.

This error message can occur because individual files cannot be deleted from the CD-RW. You cannot use the CD disc recording feature of Windows XP for random-access storage while you are writing to disc.

To set the service to Automatic, follow these steps:
1. Click Start, click Run, type services.msc /s, and then click OK.
2. Double-click IMAPI CD-Burning COM Service.
3. Under Service Status, click Start.
4. Try to write data to a CD.

I think BIOS does not having a problem only the hard drive or data corruption takes place on your drive. Use your unit's repair system. Or using installer cd to repair the damage.

Since you can boot to Knoppix try to view the hard drive contents. If it is readable then data corruption is a strong possibility. In Knoppix 5.1 drive letter is HDA1 I think for the first drive partition.

This issue can be caused by any of the below reasons.

-Corrupt boot files on the computer.
-Settings for hard disk drive are not correct.
-Floppy diskette or CD in computer causing issue.
-Boot devices not set properly.
-BIOS corrupt or misc. setting not set properly.
-Connections loose or disconnected.
-Bad Hard disk drive or other bad hardware.

Solution:


Corrupt boot files on the computer

If the computer has no bootable files on the drive it is attempting to boot from it is possible that the computer may halt at " verifying dmi pool data..."

To resolve this issue:

Boot from a bootable floppy diskette. Ensure that this diskette was made on the same Microsoft Windows operating system that is installed on your computer.

Once at the A:\> prompt type "sys c:" and press enter. This should report the message "File system transferred." Once transferred remove the diskette and reboot the computer.

If the computer continues to not boot attempt to re-create the master boot record by booting from the bootable floppy diskette again. Once at the A:\> prompt type "fdisk /mbr" and press enter. This should return you to the prompt without giving you any message. Once at the prompt remove the diskette and reboot the computer.

Note: The above information only applies to Microsoft Windows users. If you are running a Linux / Unix variant or other operating system such as OS/2 and the computer is freezing at this DMI message ensure that Linux / Unix has been properly installed first and/or your boot manger is not corrupt.

Settings for hard disk drive are not correct

The computer freezing at "Verifying dmi pool data..." may be caused when the hard disk drive settings within CMOS are not set properly. Enter CMOS and verify that the hard disk drive settings are set properly and/or that it is set to Auto Detect.

Floppy diskette or CD in computer causing issue

Verify no floppy diskette or CD is in the computer. In some cases the computer may be trying to boot from either of these drives causing issues with the boot sequence.

Boot devices not set properly

The computer stopping at " verifying dmi pool data..." can be caused when the boot devices on your computer are not set properly in CMOS. First, verify that no CD or diskette is in your computer. If a CD or diskette is in the computer attempt to remove this first to determine if it was attempting to boot from it.

If No CD or diskette is in the computer and your computer still halts at the DMI message enter CMOS setup and verify that the boot options are set properly. We commonly recommend that the floppy be set the first boot device, hard drive as the second boot device and the CD-ROM as the third boot device.

BIOS corrupt or misc. setting not set properly

If none of the above recommendations have resolved your issue attempt to reset the BIOS / CMOS settings to the factory or default settings.

Connections loose or disconnected

If the computer has been recently moved or new hardware has been installed in the computer it is possible that a connection may be loose or even disconnected. Verify that the hard disk drive, floppy and CD-ROM cables are properly connected.

Bad hard disk drive or other bad hardware

If you computer continues to freeze at the DMI message after attempting all of the above recommendations it is possible that the computer may be freezing because of a bad hard disk drive or other bad hardware in the computer.

Before replacing any hardware we first recommend you attempt to erase everything on the hard drive and start over.

If you're unable to get to the point of re-installing the operating system it's likely your computer has a hardware issue and it's suggested that the hard drive be replaced. If that doesn't resolve the issue then have the motherboard replaced.
