Hi!! I have 500gb wd passport which was running fine. But from few days, whenever i open any folder from it, its taking lot of time. I never connected it to any other PC. I tried coping files from it to my internal hdd but it was taking lot and lot of time. Is there any tool by which i can make sure that this hdd got problem, so that i can send it for replacement as it is still under warranty.
or if you can also test it by ubuntu live cd by using the dd utility
1. boot into ubuntu live cd
2. open terminal
3. change to root user by typing
sudo su and press enter
4. find you drive letter by using the command
lsblk
5. run the command
dd if=/dev/sdx of=/dev/null bs=1M (where sdx is the drive letter of your usb drive could be sda, sdb, etc.. and bs is block size of data that is written. )
Warning: don't change another drive letter in place of
null as this test will overwrite the data
