I/O device error DVD will not download software.

I also have a problem with C drive it on has 12 % free space and will not defrag. I have deleted and moved files to D drive to free up space and it just does not free up space.

My C drive has 15 GB and D has 35 GB but it uses C drive I think the partition is backwards.

How to speed up your computer's performance?

<p><b>Information:</b><br /> <p>There are some few guidelines that you can follow to maintain your computer and keep it running smoothly. <br /> <p><b>Free Up Disk Space</b><br /> <p>By freeing disk space, you can improve the performance of your computer. The Disk Cleanup tool helps you free up space on your hard disk. The utility identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files.<br /> <p><b>Use Disk Cleanup to:</b><br /> <p>&bull; Remove temporary Internet files.<br />&bull; Remove downloaded program files (such as Microsoft ActiveX controls and Java applets).<br />&bull; Empty the Recycle Bin.<br />&bull; Remove Windows temporary files.<br />&bull; Remove optional Windows components that you don't use.<br />&bull; Remove installed programs that you no longer use.<br /> <p> <br /> <p> <br /> <p><b>Tip:</b> Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.<br /> <p> <br /> <p><b>To use Disk Cleanup</b><br /> <p>1. Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.<br /> <p> <br /> <p> <br /> <p>Disk Cleanup calculates the amount of space you will be able to free.<br /> <p>2. In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list.<br /> <p> <br /> <p> <br /> <p>Choose the files that you want to delete.<br /> <p>3. Clear the check boxes for files that you don't want to delete, and then click OK.<br /> <p>4. When prompted to confirm that you want to delete the specified files, click Yes. <br /> <p>After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner and performing better.<br /> <p> <br /> <p> <br /> <p><b>Speed Up Access to Data</b><br /> <p>Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. The response time can be significantly longer.<br /> <p>Disk Defragmenter is a Windows utility that consolidates fragmented files and folders on your computer's hard disk so that each occupies a single space on the disk. With your files stored neatly end-to-end, without fragmentation, reading and writing to the disk speeds up.<br /> <p><b>Run Disk Defragmenter</b><br /> <p>In addition to running Disk Defragmenter at regular intervals, optimally monthly, certain events warrant running the utility outside of the monthly rule of thumb.<br /> <p>You should run Disk Defragmenter under the following circumstances:<br /> <p>&bull; You add a large number of files. <br />&bull; Your free disk space nears 15 percent. <br />&bull; You install new programs or a new version of Windows.<br /><br /> <p> <br /> <p><b>To use Disk Defragmenter:</b><br /> <p>1. Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter.<br /> <p> <br /> <p>Click Analyze to start the Disk Defragmenter.<br /> <p>2. In the Disk Defragmenter dialog box, click the drives that you want to defragment, and then click the Analyze button.<br /> <p>After the disk is analyzed, a dialog box appears, letting you know whether you should defragment the analyzed drives.<br /> <p><b>Tip:</b> You should analyze a volume before defragmenting it to get an estimate of how long the defragmentation process will take.<br /> <p>3. To defragment the selected drive or drives, click the Defragment button.<br /> <p>After the defragmentation is complete, Disk Defragmenter displays the results.<br /> <p>4. To display detailed information about the defragmented disk or partition, click View Report.<br /> <p>5. To close the View Report dialog box, click Close.<br /> <p>6. To close the Disk Defragmenter utility, click the Close button on the title bar of the window.<br /> <p><b>Detect and Repair Disk Errors</b><br /> <p>In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.<br /> <p>As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.<br /> <p>If you use your computer daily, you should try to run this utility weekly to help prevent data loss.<br /> <p><b>To run the Error Checking utility:</b><br /> <p><b>Important:</b> Be sure to close all files before running the Error-Checking utility.<br /> <p>1. Click Start, and then click My Computer.<br />2. In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.<br />3.

My laptop is Dell inspiron, It gives me warning of low disk spsce . At c there is operating system , in other place I remove unnecessary documents , still no solution

Hard disk maintenance should be carried once a month to make your computer run efficiently. This removes redundant and temporary files, recovers disk space and speed up hard disk access.
Disk Cleanup should be done first - Click My Computer - then right click on the C drive then click Properties, then click Disk Cleanup - let it examine the C drive then it will calculate the amount of disk space it will recover, tick all the boxes to recover the maximum disk space and then Click OK and then Yes to perform these actions. If you have a D drive then repeat these steps on this drive too.
Next the C drive needs to be Defrag. This process converts fragmented files into continuous files and this speeds up disk access and makes the hard disk not work as hard. Click on Start - All Programs - Accessories - System Tools - Disk Defragmenter - click to highlight the C drive and click Analyse - then click Defragment.
When this is completed repeat these steps for the D Drive if you have a D drive.
Disk Cleanup and Defrag can take a long time to complete, especially if these tasks have not been for a long time.

The first question to ask is what have you got on your D: drive - do you have any movie files saved there? (.MPG .AVI etc) - if so, then these should be either copied to DVD media or to an external USB hard drive.
The next question is what operating system are you using? - if you are using Windows 7 then have you set your D: drive as the target for where Windows Backup should put it's files - if so, then go into the Backup settings and change the number of System images to be kept to be only 1 and also look at how many old backups you have got - you can delete some of the older ones to make more room.
Next, you could install the free Advanced System Care utility software which provides a tool called "Disk Explorer" which will show you what large files and folders are on your D: drive and allow you to take actions to delete, move, put on CD or DVD etc to make more space.
Finally, once you have made more free space, then you would be recommended to do a Defrag of drive D: to improve the performance of the drive - again the makers of Advanced System Care provide another utility called Smart Defrag which can help with this task.
If you are using Windows XP there is also a free utility called Folder Size for Windows which works with Windows Explorer to give you an extra column you can select to show the size of folders on any drive.

My D: drive is 99% full how do I free up disk space ?

Music, video and pictures use the most hard drive space. Store them on a disc or on line storage site. After the delete or removing as advised, defrag you hard drive. This should free up space. Get rid of any programs you don't use. As long as you don't delete hidden files you should be fine. Hope this helps. If you are using windows XP go to start, control panel add and remove programs and delete only the programs that you installed and remove only them.

    Sounds like more of a software problem, I've had my dvd drive only show up as a cd drive but i think that was only in windows 98? Many problems will start showing up when your disk is very full. Try deleting some old files until you have 25% free space (only 75% full) or 20% free (80 full) at the minimum, then defragment. I recommend using a 3rd party program such as Diskeeper, since windows defrag Isn't very good.
    If you can not free up enough space because all of your things are too important to delete, think about buying an external hard drive to back up too, or simply look for a bigger hard drive of the laptop and copy the old hard drives contents to the new one using something like norton ghost.
    Most likely you would need a laptop hdd to desktop hdd converter, which is like $5 or less, so you can copy the contents since laptops can only have one hard drive (usually). If you can't do this or don't want to try it, bring your laptop to a pc repair shop and they will transfer your data to a bigger hdd for you for a nominal fee.
    Remember, I do not guarantee this to fix your dvd problem, but it is a good idea to do it anyways to increase performance and reliability.

Low space

Have you tried clearing the "Temp" and the "Prefetch" folders?
Go to Start -> Run

Type - "temp" (without the quotes) in the run dialog and delete all files with Shift+Delete.
Repeat the same operation with the prefetch folder. (Type prefetch instead of temp now)

It should be able to clear just a few MBs.

Also, I would recommend uninstalling any unwanted software that you may have installed on your system.

Also, as it is evident from your above post, you have been saving a lot of stuff in the My Documents folder. I would hereby recommend saving large files on the C Drive(D) drive so a balance would be maintained.
