seagate hard disk not detected. Does it spin? (what to do if you fried your drive by plugging in wrong power supply)\r
\r
If your seagate hard disk not detected, first of all, power it on and listen to it with your ear right next to it. Does it spin?\r
\r
If not, then it would be for one of the 3 reasons. Seized motor, unparked heads, or dead PCB (printed circuit board). There are also things like dead preamp, but on most brands of drives it would not prevent the spin up process.\r
\r
I will begin with explaining what seized motor is. Seized motor on the hard drive is fairly common issue that you would find on Seagate hard drive generations 7200.8 7200.9 7200.10 7200.11 7200.12, as well as some hitachi/IBM 2.5” hard drives.\r
Seized motor would upon start up process with create a faint buzzing, and in some cases beeping sound. I would highly suggest that you seek professional help at this point. This is one of the most difficult tasks to perform on the hard drive, and without necessary equipment you will kill your hard drive in attempt to recover it.\r
\r
However, these sounds are identical to the ones that the sound would make when heads are not parked properly. All modern hard drives offer touchless heads technology, meaning that the heads are never suppose to come in cont with the disk surface. In the past 3.5” hard drives used to park heads closer towards the center of the drive, and they would land right onto the platter surface that had air pockets to prevent sticking. That technology slowly started to get outdated and less reliable than touchless, so now hard drives park heads on the external parking ramp. Touchless technology offers more durability for the heads when the drive is off power. If it is dropped external parking ramp, that suspends heads in the air, is much better option than having heads sit on the ual disk surface. (this section is best to be read on our blog page here because I have pictures explaining the difference)\r
\r
Unlike 2 issues above, dead PCB, will turn your drive completely silent. PCB failure would usually be caused by power surges, or plugging in a wrong external hard drive power supply. Dead PCB can be either replaced, or repaired on component level. Luckily, TVS Diodes would protect most hard drives PCBs for mishaps like this, so they need to be tested first. A transient-voltage-suppression (TVS) diode or thyrector is an electronic component used to protect electronics from voltage spikes induced on connected wires. Multimeter with continuity test option will quickly determine if you have a damaged diode or not. Ideally, if you detect the damaged diode it would need to be replaced with an identical one, but in our case since I just needed to recover the data from this external hard drive. After the failed diode was removed, clients drive began to spin and get detected by our imaging equipment.\r

Characteristic of FZ1800R16KF4 IGBT - Power Electronic Modules for AC/DC Motor Control

Visit USComponent.com for more details!

FZ1800R16KF4 is an 1800Amps/1600Volts single switch IGBT (Insulated Gate Bipolar Transistor) silicon module with IGBT2. It is a triple common emitter common gate transistor. Its height, weight & depth are 38mm, 190mm & 140mm respectively and net weight is 5 lb 1 oz. This module's maximum operating temperature is 125 C and minimum operating temperature is -40 C. It can be mounted either in SMD or SMT style. FZ1800R16KF4 is manufactured by Infineon Technologies, Germany. Infineon was formerly known as Eupec and it is a famous company in the world of semiconductors and system solutions.

FZ1800R16KF4 is an excellent choice for your industry applications. It works great in AC/DC motor control & drives, Commercial, Agriculture and Construction Vehicles (CAV), wind energy systems, railway tractions. Its construction is robust and the module is highly reliable. It is recognized by UL too.

FZ1800R16KF4 has some unique features which have made it a perfect module for high speed switching applications. It features high power density for compact inverter designs. Standardized housing is another benefit of it. These features are very useful in challenging applications. Today we will discuss about the effectiveness of FZ1800R16KF4 in train tractions.

Railway traction is among the most demanding applications for power electronic modules. Climatic influences like moisture, dust and wide temperature range are challenging, so are the mechanical aspects. Power electronic suffers from the vibrations inside the trains in addition to the electric and thermal load. The mission profile of trams and subway trains consist of a high number of acceleration and deceleration cycles, repeated day by day. This mode of operation leads to extreme demands regarding power- and thermal-cycling capability. Traction system for trains employ an induction motor as the main driving motor and a VVVF inverter as a control unit, and they have improved remarkably as AC equipment especially because the main circuit semiconductor elements have rapidly improved.

There is hardly any other application that puts such high demands on the components as train traction. High quality, reliability and lifetime are the most important product features in this market segment. IGBT modules in voltage classes 3.3kV, 4.5kV and 6.5kV with enhanced mechanical and thermal features are installed in trains all over the world to allow reliable, safe and cost-efficient operation.

To suit the special needs of this application, Infineon provides FZ1800R16KF4, especially dedicated to traction and similar applications. The high-speed switching characteristic of this IGBT module lessens electromagnetic noise which is generated by the primary motor and enhances the efficiency of energy conversion. It has advantages like ongoing development for higher voltage and current ratings and these benefits make it really useful in railway traction applications. You can find it in metro drive systems, in, innovative high speed trains and in auxiliary inverters.
