Symptoms of a physically broken CD/DVD
A broken CD/DVD is an optical disc whose physical integrity is compromised, making standard reading impossible. If your CD/DVD is physically broken, do not attempt to glue the pieces back together: this action risks permanently preventing any data recovery. Likewise, do not solder the fragments together and do not try to read the disc by taping the pieces together — these attempts irreparably worsen the damage.
Why are these actions dangerous?
Any incorrect handling of a broken disc can destroy the reflective layer where the data is engraved, reducing the chances of recovery to zero, even by a professional.
Symptoms
A CD/DVD that is difficult to access is an optical disc that your computer cannot read correctly, either due to physical degradation of the disc surface or failure of the optical drive itself. According to data from the Library of Congress, a CD/DVD can degrade in 2 to 25 years depending on storage conditions.
Main Causes
- Degradation of the disc surface: scratches, oxidation, or delamination of the reflective layer
- Optical drive failure: worn laser, dirty lens, or defective mechanics
- Format incompatibility: the drive does not support the recorded format (DVD-R, DVD+R, etc.)
Yes. If there is no collection point near you, you can send your media by registered mail directly to our laboratory: Lagerhausstrasse 25, 3232 Ins (Anet). We provide secure packaging on request.

Yes. Upon receipt of your media, you will receive a unique case number. Our team will keep you informed by email at each key stage: receipt, diagnostic results, quote validation, and recovery. You can also contact our team at any time via your extranet area or by phone.
A swollen battery (bloated battery) is a real risk to data. As it expands, it can put pressure on the motherboard and internal connectors, causing poor connections, or even physical damage to the solder joints or memory chip.
Do not continue using a tablet with a swollen battery. The risk of fire or explosion is real, and the damage caused by a punctured battery is often irreparable to the motherboard.
If you notice swelling, immediately turn off the tablet, do not plug it in, and take it to a professional. Our technicians can extract the data before any battery replacement.
Yes, in most cases. A hard drive that clicks, scrapes, or makes abnormal noises generally indicates a mechanical failure of the read/write heads. It is essential to turn off the drive immediately to avoid damaging the platters. Our laboratory operates under ISO 5 certified laminar flow to replace the faulty components and extract your data.
Yes, provided that the analysis has been conducted according to recognized forensic standards. For digital evidence to be admissible in a Swiss or European court, several conditions must be met:
- Guaranteed data integrity — the original media has not been modified (use of a hardware write blocker during acquisition)
- Traceability of the chain of custody — documentation of each manipulation from seizure to analysis
- Cryptographic hashing — MD5 and SHA-256 hash calculated at acquisition to prove integrity
- Certified expert report — written by an expert who can testify to their methodology
Our forensic reports are written according to ISO/IEC 27037 standards (identification and collection of digital evidence) and can be presented before Swiss and French jurisdictions.
