Hello,
I have bought a 4TB WD external Hard Drive Model: (WDBYFT0040BBK-WESN), and after few days of use it became very slow in copying and reading data. and it’s only 1 TB full
Some files are copied at a good speed of 57~100 MB/S, and others are read only at 16~22 MB/S Max
Please help me.
Hello,
Please refer to the following KBA article: Windows: USB 2.0 Drive Slow Data Transfer Rates
We would also recommend you perform a diagnostic test on the drive to determine its optimal health (How to Install and Use WD Security and WD Drive Utilities Features)
Thank you for your reply,
I’ve already tested it on two Desktop Computers with high speed USB3 ports, and windows system is installed on SSD with 16GB DDR4 RAM and the other has 8GB DDR3 RAM with SSD Also.
