Fault: just after the warranty period for two months, the author of the Samsung Combo SM-352 (2MB cache) on the out of order. Began in the BIOS sometimes does not recognize, and later sometimes even to recognize, however, was identified in the Windows CD, read the disk error. Herbalife used to take account of the total time is not long, that should not be so quickly broken, so suspect a problem with motherboard IDE Interface - for another interface, suspect data line problem - replace the data cable, but still no solve the problem, occasionally a good look soon not do. Recently spent five consecutive late moment, aware of the combo is over, forced to buy only the first BenQ DW-1640DVD recorder emergency. As has been 杩囦簡淇濅慨鏈? maintenance costs will be higher, since DVD burners are, and also to pay repair Herbalife? Try as their own.
Maintenance:
1. Open Herbalife's tray, tray under the first baffle, and pay attention to plastic cards not broken; then they withdrew the Herbalife panel.
2. Unscrew the four screws, remove the metal case, can see the shaved head components and circuit boards. Herbalife clean inside, outside is new, shaved head is also clear, plug in the power, skinhead movement twice Seeker correct, laser normal light (Do not look directly at laser with your eyes, shaved head side to see a red flash on good). I did not go to adjust the laser power, but to carefully remove the concept of circuit board inspection, and then wash your hands before touching the circuit elements (static over the winter to prevent the breakdown PCB on IC). Combined with the previous analysis of phenomena, it is the poor contact? This common fault, however, the power and data lines from the start pad.
3. Tools: 20W electric soldering iron, conditional on the ground. Quickly to the power connector and data cable and circuit board solder re-solder again, do not make up solder.
4. Access to the computer test. BIOS successfully identified a combo, also recognized the right in Windows, burn a data disk, verify the correct, sure is a IDE interface, loose weld and repair.
Consideration:
As the DIY, often swap hard disk drives and the passage of time will give rise to loose weld, while the Samsung SM-352's power connector and data cable is directly soldered circuit board, plug easily cause frequent loose soldering. This reminds me of my previous damaged Maxtor 541DX hard drive failure phenomenon similar to the computer market at that time to repair, plug in the power, hear the hard drive motor rotation, it said can not repair. I think that is the problem then the circuit should be able to repair; although I doubt they explain, but it also had to give up on one side, the hard disk would be a reason? Find out the hard disk and found the same with the Samsung combo, power connector and data cable is directly soldered on the circuit board, next door, and the hard disk has successfully revived, formatted properly used.
Summary: DIYer found hard disk drive or read and write error, have noted the power lines and data lines, but little to check the IDE drive or hard disk interface, in this regard is the warranty time frame yet to come, worried that they moved manufacturers do not warranty, on the other hand, they also think that the hard disk even after complex no start. In fact, as long as the CD-ROM or hard disk is not convinced that burned hot, and occasionally can read or write, mostly caused by loose soldering or poor contact. To sum it up: plug the interface often prone to loose weld failure.
