Hello to all,
I m a beginner in the Linux platform. Since last two years,i was
working on Embedded C,C++ on the keil compiler, on the 89C51RD2. I have
also worked on the WinCE 5.0 Platform Builder with EVC++.
According to my new project, i would like to write the diagnostic
application for the PC type device (32 bit processor) i.e i have to
test the functionality of each and every hardware like CPU,HDD,Serial
Ports,RAID,etc.The client has given the procedure to carry out each
test.
The software would be developed predominantly in C
Library and Driver would be developed for Linux Kernel 2.6.14. The
development tools would be GCC Ver. 3.4.4, Glibc 2.3.5 and Binutils
2.16.1
As per the requirement the procedure to test HDD should be
# Check HDD
1. Validates the hard-disk device by writing a pattern onto an unused
sector and compares with the expected pattern.
2. Checks all the sectors (HDD surface test) and report bad sectors.
3. Retains the original sector contents.
Can anyone please help me to start the application.
Please guide me...
Thanks and Regards,
Nutty.

badblocks -n /dev/hdX
It's part of the e2fsprogs package: http://e2fsprogs.sourceforge.net/

For HDD diagnosis, there are smartmontools. Most current harddisks have
SMART technology, they count how often they are turned on, how seek
times develop over time, how many defect sectors have been
automatically replaced by the builtin logic, and a lot more.
The tests you suggest make sense for harddisks without any builtin
logic, where the user and the OS take full responsibility. You might
want to rethink your goals.
