Hi i went through your blogs regarding the IT support, I have Samsung laptop and for last one week it is given me problem, my laptop hard drive has 2 partition by the name of C and D, whatever iam doing on C drive like to open my computer or documents it is taking too long and the main reason to message you is that it is showing a D drive partition in 'MY COMPUTER' but it is not opening, and all my data is saved in D drive, I even tried to installed new windows 7 but still is same, I tried to use option of disk defragmenter but it's say 'invalid parameters' I tried to used bitlocker option but same message I got invalid parameters, I don't want to lose my data, iam confused that if the problem is with hard drive then why C drive partition is working and D is not, when I right click on D drive for properties it Is taking too long, I will highly appreciate you if you can help me I don't want to lose my data thanks
