I cannot view data from my external hdd in my laptop but it is visible in anothe

Hi,

I have a Samsung External HDD 1 TB, the same was working fine till some time back. My bro plugged it in his Sony Vaio laptop for viewing some files. After he doing this, now whenever I try to plug this HDD to my Dell Latitude E5400, I am unable to view files or data stored within this HDD.

Reconnecting the same on Sony Vaio again, all of the data is visible. Dont know where the issue, please assist in restoring/viewing my data on my Dell latitude.

Thanks.

Regards,
AJ
