Fun-digital is back
Recently I have so many things that I have done through. I learnt a lot of things back there. Starting at op amp circuit, transistor circuit switching, speaker audio, microcontroller, DC motor, and in programming is artificial neural network. All of them are for my final project.
Recently I looking forum that will help me through any obstacle. What I am facing now is FINAL PROJECT. Searching, Researching, Coding, Compiling, Testing, and Failing are my daily activity.
Now I am stuck because MicroController I use doesn't have a lot memory and more complex is my compiler doesn't support large code to compile cause DEMO LIMIT.
I hope This list of electronic forum will help me.

The title is same MicroController, Neural Network, and Sooound Localization because my final project title is
DESIGN AND IMPLEMENTATION OF MOBILE ROBOT SOUND TRACKER BASED ON ARTIFICIAL NEURAL NETWORK.
This is based on my experiences. Almost a month I scan, format, and wipe my flash disk. Finally conclusion appeared in my mind.
Please note, these technique work for me and maybe don’t work for you. If your Flash Disk is under warranty it is better to get new one before your try these techniques. Try to read your i/o flash disk with some utilities so you know it is not physically damaged. I use Ontrack Easy Recovery Professional which has Data Advisor diagnostic features because I think it work on flash disk too.
These Techniques are works for flash disk drive / pen drive.
-> Just format your removable disk. You will find some hidden file after that.
-> If this file is not contain or not virus, do scan disk. How do I find it is under virus or not? The answer is I don’t know it either. There are several trick to know it but I can’t write it know because the virus issues has been rapidly grown up.
-> Format it! If you can’t format it, it means you can’t fix your flash disk. Format it with FAT 32, not FAT 16 or you will be sorry. It is worked! If it is not, I cannot help you.
-> Format it with FAT 32, not FAT 16 or you will be sorry. Some time is working, some time is not depend on your flash disk condition.
-> This message only can be repaired by destroyed data utility or wipe utility. This software work for deleted or formatted data to be destroyed and can’t be recovered. I used Ace Utilities that has 4 methods, Pseudorandom Data, US DoD 5220 22-M (8-306./E), DoD 5220 22-M (8-306./E,C and E), and Gutmann. After that you can check your flash drive with Format Recovery, not Delete Recovery, because they are different. I use Ontrack Easy Recovery Professional. . If it doesn’t work, format it first then wipe it.
-> If you cannot fix it, see the progress bar of wipe utillity. It is finish or not. If not you can not fix it with any utility. First try low level format first. I don't know what kind utility to work with but I think it will work.
-> This the last. Try copy large file into your flash disk. The bigger file better result. Then when after you copy it, "Write Protected Error Message" will appear. Don't worry! After this you will face Problem no.8 "My File is Empty but Used Space is Above xxMB".
-> Same with previous error. This message only can be repaired by destroyed data utility or wipe utility. This software work for deleted or formatted data to be destroyed and can’t be recovered. I use Ace Utilities that has 4 wipe methods, Pseudorandom Data, US DoD 5220 22-M (8-306./E), DoD 5220 22-M (8-306./E,C and E), and Gutmann. After that you can check your flash drive with Format Recovery, not Delete Recovery, because they are different. I use Ontrack Easy Recovery Professional. If it doesn’t work, format it first then wipe it.
-> I don’t know how to fix it because I never face it before. My analysis, same with Write Protected Error Message, is format it first then wipes it.
-> Symptom’s are almost same with Write Protected Error Message but it can not be fixed. I tried to use hdd regenerator that working on hard disk but no flash disk drive found. If you format it, Write Protected Error Message will appear. What should I do? Never mind. Just use your flash disk. If Write Protected Error Message appears, format it. Then Write Protected Error Message will appear after you copy some big files into it. Don’t worry. Click OK Button. You can still use your flash drive but you lose certain space.

I hope everyone is having fun if these methods don’t work. Otherwise YELL at me please... Read more...
With happiness I am posting at this post. Continuing about yesterday post, today I finally realize I did. I fixed my flash disk. I spent a whole night, more than 7 hours to fix my flash disk. Than this morning after did several test to my flash disk, I know I fixed my flash disk.
I don’t give you a full report how to fix my flash disk yet. But I will post that report in the next post about “How to fix Your Flash Disk”. The reason is I want to give you special posting for all
A Good News Becomes Bad News. Yesterday I spent a whole day to figure out how to fix my flash disk. While I do that, I prepare to finish my final project. Although I tend to learn about my study, last night I actually fixed it. A good news become bad news when I found my self damaged again this morning. What?
My flash disk was damaged by unknown thing. In digital circuit a lot of thing could happen anytime anywhere. My prediction is my flash damaged because deleted corrupted file, bad sector, or flash disk circuit problem. How to prepare my flash disk? My flash disk problem is about the difference in initial capacity and actual capacity. Of course the actual capacity became smaller to the initial capacity. The actual capacity is 114 MB and the initial capacity is 4GB. What!!!
Yesterday I try to fix my flash disk. My motivation to fix my flash disk because I am currently Electronical Engineering and my speciality is Digital Electronic. I can’t tell you this product name because it be able to shame company reputation. I try to fix with two tools, recovery tools and optimizer utility tools. I can’t tell you the product name either. He..he..he..
While scanning, formatting, and wiping my damaged flash disk I read book about mathematical tool in C++ and Java. I can’t tell you the book title because I don’t remember the book title because my book in my home and I post at campus. I plug in my flash disk in my lab computer in my campus after that I realize that I can not copy to my flash disk again. Sigh..
