I have a WD Passport 1TB, USB 3, external HDD. Recently I have accidentally (and stupidly really!) erased my data, by trying a **bleep** Unlocker utility, in my attempt to just normally disconnect my locked (for some unexplained reason) WD Passport under Windows 7.
Anyway, after that I have decided to copy all my movies back into the drive, but I noticed that it has become very slow. Specifically, I could copy from my internal HDDs to the WD Passport at about 70-80 MB/sec and after the accidental deletion I could see speeds of 3 MB/sec!! So, I have decided to format that drive. I tried both Smartware and Windows 7 Format. First I tried with the Smartware, but I could not see any improvement. Then I tried with Windows 7 format, but I noticed the same, i.e. no improvement.
I have also tried to "Wipe" the disk, using EaseUS Partition Master and then Format, using the same, or using Acronis Disk Director 11 Home software. The only improvement I could see is that it starts copying with good speed, of about 70-80 MB/sec, but after 3% of the copying, then it falls down to only 9 (!) MB/sec, and until the copy finishes!!
Can you help me to fix my drive, so that I can again take advantage of the USB 3 speeds ??
Please note that I have the ASUS P8Z77-V Deluxe motherboard and I have tried to use both the back USB 3 Intel and other ports and also the Front USB 3 connector, with the exactly same speed results for all cases. Also, I have 3 other WD Passport 1TB, USB 3, on which the speed is as expected!
So, I am convinced that there is no problem with my USB 3 ports of the motherboard and this is a problem of the specific WD Passport 1TB.
Please let me know o your suggestions, because I am dissapointed and frustrated with this WD Passport problem and I need to backup movies on this drive the soonest possible.
