Hi, This is my first post in LTT forum. My external hard disk WD Passport Ultra 2 TB has become slow these days. Initially I was getting over 100 MBps transfer speed and that reduced to 30-35 MBps now. Having this problem for 3 months. I have tried defragmenting and optimizing the drive but that did not solve the issue. I did not try formatting the drive because I have over 1.2 TB of files and I do not have another hard drive to transfer these. Also as per tests there are no bad sectors. The only problem is slow transfer speeds. Any help to solve this problem is appreciated
