HDD PCB ttest and repair skills

1. Check whether the CMOS SETUP lost the HDD configuration information. Test the motherboard’s COMS RAM circuit. Battery failure or components (such as such as diodes, transistors, resistors, capacitors, etc.) corruption will caused the CMOS configuration parameter error.
 
2. Power on the HDD, If the screen displays the error info”1701” or “Hard Disk Error”, it means the HDD is faulty. However, it also can caused by HDD adapter card is not inserted, or tucks hard disk and hard disk adapter is not plugged in, or the HDD adapter damaged, etc.

3. Turn off the computer and open the cover. Test the +5V、+12V power supply is normal or not, the power box fans can spin or not. In order to determine is the external circuit power shortage.

4. Check the signal cable:  plug and the HDD adapter card are connect well or not; is anti-inserted or poor connected. Can change some cable plugs to try.

5. Using “alternative method” to determine the faulty parts. Using a good HDD adapter card (or multifunction cards) compared with this HDD adapter card, in order to judge the problem was caused by HDD adapter card or HDD itself.

6. Check the stepper motor’s stopper pin. If it was stuck, put back it to the starting position.

Note
As above steps, user need carefully check, test, analyze, and identify bad components to repair or replace the HDD adapter card.
After the above processing, as long as the HDD is not damaged, we can resolve the above problems soon.

Data Loss–Biggest Fear in 2014

IT professionals face a multitude of issues each day, but none are larger than the threat of losing data or failing to properly backup and secure mission-critical information, according to a new survey of 230 IT workers by Iron Mountain.

“As the volume of data continues to explode, companies are strapped with how to cost-effectively archive that information and protect it from potential data loss. The only way organizations can accomplish these goals and overcome their limited budgets is to store smart with a mix of cloud, disk and tape technologies.” says Jay Livens, director of product and solutions marketing at Iron Mountain.

Livens’ point is well-taken. With an increasing number of companies relying heavily on digital data, the onus is on IT pros to use any means necessary to keep company data backed up and secure. And sticking with a single solution, like just a public cloud or just tape is no longer a safe option.

Data Loss Keeps IT Pros Up at Night
A solid majority of IT professionals—68%—say data loss will be their chief concern during next 12 to 18 months.

1

Data Volume Remains a Major Risk
Challenges abound in the IT world, but none are greater than the rising tide of data. In fact, there’s a 77% chance that massive amounts of data will be a major challenge for IT pros for the next year or longer.

2

Limited Budgets Still an Issue
The U.S. economic might be in recovery mode, but 62% of IT professionals say that their organizations have limited funding for data management and protection.

3

Tape Isn’t Going Away
Although cloud computing is considered the future of storage, tape offers several distinct advantages, according to IT professionals, such as costing 15 times less than a SATA disk.

4

IT’s Daily Dose of Data Issues
Having IT involved in data management is extremely important, and 92% of IT professionals say that they’re involved in the day-to-day management of data issues and make data-related decisions with the business side.

5

Early Adopters But Users of Tape
Fifty-five percent of IT pros say they’re “early adopters” of new technologies, making the heavy reliance upon tape, and the desire to be involved in issue management, a key concern for these folks.

6

Cloud Has Room to Grow
Cloud computing has significant room to grow in the coming years as just 64% of companies say they store their data in cloud-based services.

7

Disk Storage Stands Tall
Not surprisingly, disk storage is a huge investment for companies, with 85% saying that they rely on disks to keep data safe.

8

Tape’s Low Cost Matters Little
Tape is inexpensive, but IT isn’t convinced of its value. Only 53% of companies currently store sensitive data on tape.

9

It All Comes Down to Cash
All of this information underlines one important point: data-retention compliance is extremely important. In fact, the average cost of complying with data-retention policies is $3.5 million. When companies fail to comply, that figure jumps to $9.4 million.
