While DVDs and CDs are slowly becoming obsolete, many of us still own hard copies of our all-time favorite films and albums. Unfortunately, discs are prone to scratches, chips, and general dirt buildup, often rendering them useless. However, there are workarounds and hacks for getting your damaged hard-copy media working again. Read on to see what disc repair methods we recommend.
What you should know before you begin
It's important to note that the methods outlined below will not work with Blu-rays. Those discs use a harder coating that's more difficult to scratch and damage, which is good, but the downside to this is that once it does scratch, it typically becomes unusable and has to be replaced. Minor damage may be corrected with a microfiber cloth, but the data density and layers prevent any of the options featured here from working particularly well or even being advisable for a Blu-ray. Error-correction features on the best Blu-ray players may help them to ignore scratches, of course.
Five tips before you start
Although we cover different methods for cleaning and resurfacing your discs, it's important to remember a few key rules if you want to save yourself a headache while going through the process.
Wash and dry your hands before handling your discs. It's surprisingly easy to mess with the delicate data imprinted onto a disc's polycarbonate layer, and both grease and oil are known to cause playback issues even if the disc shows no signs of physical damage. Better still, put on a pair of latex gloves, if you happen to keep them around.
The best way to clean your discs is to start at the center and work your way outward in a straight line. This allows for a better grip while cleaning and lets you avoid damaging any of the data printed onto the polycarbonate layer below. The reason for this is that the data runs in a spiral around the disc, as on a vinyl record. Because the disc spins so fast, the reader has to be able to compensate for missing bits of the data as it goes, and when a scratch runs straight out from the center of the disc to the edge, it's a lot easier for the algorithm to catch the error and fix it automatically.
Tray-loading drives may be more likely to read a damaged or scratched disc than slot-loading drives. If possible, it's a good idea to use one of these drives when trying to salvage a disc to lower the number of variables at play.
Given that the layer of data that is encoded onto the polycarbonate surface is so close to the top layer of the disc, scratches and dents on the label can cause read errors in the same way a ding in the reflective surface can. Make sure to store all your discs in cases or on spools, and handle them by the inner ring to avoid damaging the data.
There are all sorts of ways you can damage a disc, but it's important to identify how deep a scratch is or what caused the disc to malfunction before proceeding. The first trick is to confirm that the problem is actually with the disc. This is usually done by trying to play the disc in another device that has a disc drive or inserting another disc into the original drive that gave you issues.
