the gradual, natural deterioration of the magnetic field. This is less likely in media that is mostly read-only, such as optical media, unless the writing device is defective. A previous Write on a nearby physical location caused the head to corrupt bits in the read location (imprecision in the physical write location). Hi, I got some 4K movies for Christmas and also got a new 4K drive to rip using MakeMKV: I then tried to rip Mulan and Fifth Element which are UHD discs and I a getting this error: MakeMKV v1.15.3 win(圆4-release) started Using direct disc access mode Loaded content hash table, will verify.dust particles) physically harmed the medium, or caused the head to harm the medium. scratched it), corrupting data in the location that is now discovered as problematic. Previous operation of the disk harmed the medium in some manner (e.g.The hardware problem can be poor cabling, incorrect termination. The head executed a Read request while being improperly aligned, causing it to read data from a wrong physical position. The source may be the controller or (more probably) a device that is attached to the controller.This is due to the device retrying and attempting to recover from the error.Įxamples of conditions that might cause medium errors Medium errors are often associated with long latency for the IOs. 5.0 out of 5 stars Excellent for Archiving 4K, Blu-ray, and DVD Discs - and It IS LIBREDRIVE Compatible. If the medium has incurred permanent damage, the device might remap the logical address where the error occurred to a different, undamaged physical location. However, if you have a 4K-friendly drive and want to rip a 4K UHD disc, you'll need to open MakeMKV and see if your drive is compatible with 4K discsagain, see the MakeMKV forum (Opens in a new. Locations of medium errors can be either temporary (as in the case of bit rot – there is no damage to the medium, the data was simply lost), or permanent (as in the case of scratching – the physical location is unusable from that point onwards).ĭevices can sometimes recover from medium errors, either by retrying or by managing to reconcile the data with the checksum. The mismatch of data to its supposed checksum is assumed to be caused by the data being corrupted. Medium errors are most commonly detected by checking the read data against a checksum – itself being most commonly also stored on the same device. protocol, device/controller/driver state, etc. The word "medium" refers to the physical storage layer, the medium on which the data is stored as opposed to errors related to e.g. ![]() ![]() ![]() In digital storage, a Medium Error is a class of errors that a storage device can experience, which imply that a physical problem was encountered when trying to access the device.
