“Clicks of Death” – what is it?
This is such a situation when the drive has lost its ability to read the servo track for proper head positioning. At the same time, the drive does not “see” where its heads are and interrupts the operation of writing / reading data. Then the heads are removed from the cartridge and a click is heard. In such a situation, the Iomega strategy involves repeating attempts to read data, having previously wiped the heads and returned them to their original position at the zero point. During “wiping”, head contamination and electrostatic charge should be removed. After that, the heads are re-inserted into the cartridge to try to read the information and a click is heard again. And these attempts can be unlimited, and taking Zip out of the situation when the drive “clicks” is sometimes not easy.
The Zip Iomega device starts clicking due to an incorrect write to removable media or due to the inability to read data. Incorrect writing to disk can damage user data, low-level formatting, servo information about the location of the heads, and the Z-tracks themselves. The inability to read data occurs when the head malfunctions, is damaged or breaks. A click is an audible sign that the device has problems accessing data.
Studies have shown that there are three reasons for the appearance of “clicks of death.”
Causes associated with the physical condition of magnetic heads or floppy disks
Usually result from the fact that magnetic particles consisting of iron and neodymium damage the read-write mechanism of the drive. The material that the disk consists of also decays, forming a solid continuous coating on the heads of the drive, which does not allow the heads to read the disk and leads to its subsequent destruction. Contaminated heads can also come in contact with the edge of the rotating disc, which can lead to breakage of the heads.
Reasons related to the influence of external factors
Causes of clicks due to external factors can be power outages and faulty connectors, which is especially true for external (external) Zip drives. Defects in manufacturing, excessive wear and tear, and magnetic and radio interference can also lead to “death clicks”.
Reasons for the abnormal operation of the electronics
In the event of an abnormal operation of the electronics, situations may arise when information is written to the disk to places not provided for this or if the accepted agreements are not observed. Such a record can be so different from the standard that it can also lead to “clicks of death”, because there is a lot of service (factory) information on the floppy disk, which may be damaged as a result of such a recording.
