As a word of warning, some of the steps may involve treatment to the surface of the disc to correct reading errors and it is important to note that they may NOT

be applicable to Blu-ray discs. Blu-ray discs are manufactured differently and only light polishing is suitable for them. Doing otherwise may result in permanent damage to the disc surface that may render the disc completely useless. The main difficulty in starting out is that you are most likely getting some kind of error message from the disc reader and you think that the problem is from some particular source because of that message.

Common error messages such as Disc Error, No Disc, Invalid DVD Navigation or even Invalid File Structure tend to make you think you have a problem disc… not a problem reader. The reality is that these and just about all other error messages you may get are essentially meaningless and are telling you nothing. They are simply pre-written error messages that may randomly appear from within the software when ANY kind of problem occurs. They are not the result of some hidden and highly technical diagnostic process having been carried out by the software! It’s just smoke and mirrors! You can place a faulty disc into a reader and have it report that there is No Disc… which is just silly because obviously there is a disc in there! So let's get started. Is It A Disc Error or a Player Error? If you have a disc that won’t play in a particular device the first thing to do is to take the disc out and inspect the surface of that disc in good light. Angle the disc so that you can see the surface clearly and not just reflections. Look for any obvious scratches or marks or even heavy fingerprints or dirty areas. The key area of the disc to check is right at the center wher

through the official package system are often sufficient for performing this critical task. One particularly frustrating way to lose data is by burning copy it anyway it to an optical disc and storing it. One often attempts to preserve data this way, only to have cheap media or a cheap storage container (especially binders) destroy the disc beyond repair. Sometimes, however, the data around the http://diyvideoeditor.com/guide-to-dvd-cd-game-disc-repair/ error (or at least up to it, which is sometimes still better than nothing) may still be readable if you use a tool more complicated than the 'cp' command (or selecting and dragging files in the file manager of your choice.) Copying an entire disc One excellent starting point is to use GNU dd (from GNU coreutils) or other, similarly capable implementations to recover the data on a damaged optical disc (though perhaps not one so damaged as the http://hyperlogos.org/page/Recovering-damaged-CDs-or-DVDs-Linux one on the right.) A handful of the available options are especially helpful. Here's a possibly excessive example command line for copying a whole disc: dd if=/dev/sr0 of=image.iso bs=2048 conv=noerror,notrunc iflag=nonblock dd is an exceptionally useful utility. The GNU dd manpage says of dd that it will "Copy a file, converting and formatting according to the operands." We don't do any conversion, but we do specify some options as to how to go about reading the data: From my first cd-rom drive (if=/dev/sr0) I read to an appropriately named ISO file (of=image.iso). I specify a block size (bs=2048 means 2048 bytes, or 2 KiB) and some options (conv=noerror,notrunc): noerror causes dd to continue after a read error, and notrunc will avoid any automatic truncation of the output file. iflag=nonblock sets an "input flag" that causes dd to use non-blocking I/O, which should minimize the impact on your system at the possible expense of speed during the copy. Since I always assume that the copy will take a more or less indefinite period of time, this does not offend me at all, but I admit that it also helps to have an external DVD burner lying around as a backup in case I change my mind and decide that I really need my DVD-ROM. This is what it looks like when there's errors: dd: reading `/dev/sr0': Input/output error

In the case of data CDs (CD-ROMs), the drive cannot properly read the CD, thus giving rise to reading errors. In the case of audio CDs, the CD skips when we play it. The https://neosmart.net/wiki/a-disk-read-error-occurred/ first thing to do when coming across a CD with a read error is to clean it in order to check if the error is being caused by a dirty surface. You can even wash the CD gently how to with a little detergent, using your fingers to clean it. (Avoid sponges, since they can scratch the CD.) If the error persists, try reading or playing the CD on another drive. If another drive (or CD player, in the case of audio CDs) gives the same result (read error) (or skipping, in the case of audio CDs), it will mean that the CD is scratched. Looking at it against the light, the recording surface (the flip side how to recover of the label) of a CD with this kind of trouble will allow you to easily see one or more existing scratches. A CD's data is recorded on a metal layer inside of it. This is a silvered layer on commercial CDs and is oftenly golden on CD-Rs. The metal layer is inset in a transparent plastic covering (polycarbonate) used to protect the CD's metal layer and to allow printing a label on the side not being used for reading. A CD-ROM drive or CD player utilizes a laser beam, which crosses the plastic layer and reads the metal layer. If the plastic layer is scratched, the beam will be unable to pass through it, resulting in a read error or skipping the music. In other words, if the data to be read are still in the CD, the trouble lies in the layer of plastic. As the CD's contents are preserved, a scratched CD can be recovered by polishing its plastic surface. After carrying out the above cleansing, if the CD persists in giving reading errors, just polish the scratched CD with toothpaste. That's right, toothpaste. It works wonders, and you won't spend a fortune buying professional cleaning kits. Polish the scratches with a cotton swab, gently rubbing the paste-imbued swab over the scratches until they disappear or until you notice that you have removed them as much

Description and Symptoms The error messages, alerts, warnings, and symptoms below are tied to this error. Symptom 1: "A disk read error occurred" error screen on startup The "A disk read error occurred error" appears on a black screen without an identifiable error code. Pressing the Ctrl, Alt and Del keys will only restart the computer and boot into the same error screen: A disk read error occurred Press Ctrl+Alt+Del to restart In most cases the error can appear for any of the following reasons: Incorrect or invalid MBR configuration Improperly configured partition table Faulty hard drive IDE cables failing Bad RAM memory Issues with your computer's BIOS version The most common cases of this error are attributable to an incorrectly-flashed MBR to the system startup disk or the absence of an active partition on the startup disk. In these situations, the recommendations below should resolve the problem readily. If the problem is with hardware, additional diagnosis and the possible replacement of system components may be needed. Causes of this Error This error has been known to occur as a result of one of the following causes: Cause 1: Incorrect or invalid MBR configuration The most common cause for this error is an incorrect MBR configuration. This is usually caused by disk write errors, virus attacks or power outages. Cause 2: Misconfigured partition table For the same reasons, the partition table may become misconfigured. If that's the case, it is possible to rebuild the partition table from scratch to make sure system loads correctly.
