28 portion of the drive where information is written cannot be accessed at all by the unit. It is most common in spinning disk drives, where the actuator arm inside of the drive is used to retrieve information from rapidly spinning platters. If the arm is knocked out of alignment, it may be unable to access part of the platter in order to retrieve its contents and send it to the computer. Or, if dust settles on the platter, it can act as a barrier between the platter and the arm, also interrupting communication. In extreme cases, the actuator arm may make direct contact with a platter, scratching it and permanently damaging the data in the same manner as a scratched DVD or Blu-ray. In this case, recovery of damaged sectors may be impossible. If this occurs, users may hear a distinct clicking or scraping sound coming from the drive when it is powered on. This is a screaming red flag and the device should be powered off immediately as each clicking or scraping noise is the sound of data being permanently destroyed. In the case of solid-state media, bad sectors can occur when memory cells age and fail as a result of constant use, similar to the lithium-ion batteries found in cellphones. Unlike logical drive failure, where a variety of consumer options exist to resolve the issue and recover media, mechanical hardware failure is almost always beyond the means of a user to fix on their own. Advanced technicians utilize sterile clean room environments to perform surgery on damaged drives. Functional components are removed from the damaged devices and transplanted into new units. Dirty or corroded mechanical platters need to be chemically treated in order to clean them. The entire process is incredibly delicate, as dust or fingerprints on a physical disk is more than enough to ruin the entire transplant procedure. As a result, this process can be expensive and estimates can vary from a couple of hundred dollars up to several thousand. Fortunately, unless the actuator arm has actually scratched a drive's platter, spinning disk drives currently have an estimated ninety nine percent successful recovery rate, with a success being defined as a recovery of at least ninety seven percent of a user's data. The last category, complex failure, is simply a combination of any of the above errors. A drive can fall from a table, yanking it out of a computer during transfer in a manner that damages the partition and creates logical failure before it crashes to the floor, knocking its actuator arm out of alignment and causing bad sector mechanical failure. At this point, the unit would require multiple troubleshooting steps in order to recover the information within. Unfortunately for most users, the outcome is the same as if the device had simply suffered mechanical damage and the unit will almost certainly need to be sent to data recovery experts for repair. In the event of a drive failure on set, Local 695 members should never attempt troubleshooting or repair procedures without first discussing the matter with their head of department or a producer and informing them of the potential cost and the risks involved. In the event of logical failure, it is possible to salvage a production's data and save both time and money—always a good thing when negotiating your next rate. However, if mechanical or complex failure is the suspected culprit, it is probably best to turn the faulty drive over to someone with decision-making power and recommend that they consult advanced recovery specialists.
