Checking the status of the Zip drive

TIP.EXE is a Zip disk surface quality test. The principle of the program is as follows: this program reads each sector of data from the disk, enters them into the computer’s memory, and in the free sector writes / reads special test sequences. Your data is saved when the device functions and the surface condition of this cartridge allow. Continue reading

“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. Continue reading

Z-tracks

In devices with a moving coil there are no pre-fixed positions. Instead, they use a special guidance system (positioning), which accurately brings the heads to the desired track.

The system of precise guidance of the heads on the tracks is called a servo drive, and for its operation a feedback signal is required that carries information about the real relative position of the tracks and heads.

Temperature fluctuations do not affect the accuracy of the drive. When compressing and expanding disks (rotation, temperature), all changes in their sizes are monitored by a servo drive and the positions of the heads are adjusted. Continue reading

After checking all the computers and installing, where necessary, the recommended boards, will the 2000 problem be resolved?
Of course not! Most of the problems will remain. The danger of the 2000 problem is that in recent years, very large databases have accumulated in any organization. In these…
