Flash drive repaired ~ Haha !!!

I have printed my resume at two ends in the last three days. I am sorry to borrow a USB flash drive from someone else every day, so I flipped through the drawer and found a bad USB flash drive. After the USB flash drive is connected to the computer, the drive letter is displayed. However, when you double-click it, the system prompts "Please insert the disk into drive I :". When roommates were about to throw the shell, they all opened it. I think the hardware is not bad. (How can the current electronic products be broken?) It has the value of hands-on repair, and I will pick up the poor "core. Today I took a night shift and studied it. Well, I have fixed it.

Problem description: U Disk Master icreate company i5068-Z (may also be a i5062-Z can not see big clear ). The flash memory is star RAM (256 MB ). After connecting to the computer, it can be recognized and displayed as drive letter I. When you double-click the disk, the system prompts "Insert disk into drive I ".
Analysis: I have not studied the principles of flash memory. I think it should be similar to hard disk-it is also composed of "Driver controller + Memory. It is shown that the USB flash drive is a small black block with two rows of feet. The computer can properly identify, at least it indicates that the hardware of the driver controller is okay, so the problem is on the flash memory: Virtual soldering, or boot program error.
After searching on the Internet, some experts said that normal identification indicates that the hardware has no problems (that is, it is impossible to perform virtual welding ). So
It is on the boot program. We only need to find the formatting software corresponding to the driver controller.
Go to the icreate official website. There are many good things, but they cannot be downloaded. It seems that they use it internally.
Go to Google and search for "icreate6 i5068-Z format. There are quite a few of the "general" and there are not many problems that can be solved. We finally found a Taoyuan Holy Land everythingusb .) Download the pdx8_2k_v327.zip file. (After testing, the lower version cannot solve the problem, and there may be a later version of v328 ). E is not very good. But I still understand that many people have used the stuff provided here to fix it. Download it. The first attempt failed. The following is the report of the first error fixing:

Pendrive 1: fail
Controller ID: a8062, 103
Flash 1 ID: 0x2c 0xda 0x80 0x15 0x50 0xff 0xff 0xff
Err MSG: system error, please contact and tell us the error no.

You can find this report in function-> report.
I tried it several times and finally got it done. The following is the post-repair report:

Pendrive 1: Good
Controller ID: a8062, 103
Flash 1 ID: 0x2c 0xda 0x80 0x15 0x50 0xff 0xff 0xff
Flash 1: Id 0x2c, good blocks 2046, Bad Block 2, total blocks 2048
Flash 1 Capacity: 268173312 bytes
Total useable sector: 523776 sectors
Total useable byte: 268173312 bytes

Note some settings. Select function-> option from the menu. On the flashtest tab, select the check boxes "low format" and "Burn-in test.

If the test fails, try other options. When you click "run", the villain keeps running and the numbers next to it keep changing, congratulations! Your USB flash drive is being formatted in a low-level format. After completion. The villain turns into a green icon and prompts "good!

Formatting is a slow process. It took me 20 minutes. I did not touch my computer in the past 20 minutes.

What is a Bootstrap program? I believe you have heard of the word "formatting. A new disk has two sides, and one side has a circle like a tree ring. Such a disk cannot be used. Formatting marks the segments on a disk (the so-called mark refers to the South and North Poles with regular geomagnetic conversion). It is called a segment, these tags indicate in sequence the location of the circle (column) of the disk (surface) on which it is located (sector ). The area between tags is used to store files. In this way, the computer can find these files according to these tags. The Bootstrap program is a program written in a specific location on the disk during formatting. It will tell the computer how the disk is marked (that is, the disk format we call, fat or NTFS ). Without this program, the computer will not be able to identify the disk correctly. It will prompt that the disk size is 0 MB, the disk cannot be formatted, and the drive letter cannot be found.
The boot program is sometimes damaged. This problem can be solved through low-level formatting. Low-level formatting will overwrite the boot program. Different disk drives require different low-level formatting procedures.
