Hi All-
I purchased a WD Elements External HDD USB (2TB). When new, transfer rates from my PC internal HDD to the driver were decent. Then they slowed to a crawl.
For example, when new (02/10) backup of 80GB music collection took ~75 minutes using GoodSync. Couple of days ago it took 15 hours! Transfer rate hovered around 1MB/s.
System specs:
-Pentium 2.8GHz processor
-Physical Memory 1024 MB 533MHz 64 bit DIMM x 2
-USB 2.0 Intel 82801G (ICH7 family) with current driver
Drive is connected to PC using a standard USB 2.0 cable.
I downloaded the WD Lifeguard Diagnostics disk utility. SMART status indicated fail (re-allocated sectors) so I contacted WD tech support. Per tech, the utility does not work on drives over 1TB. The rep had me re-format the drive, creating a single, primary NTFS partition using quick format. I then scanned the drive for errors/bad sectors using XP chkdsk, HDTune Pro, IObit Advanced System Care. No bad sectors, no errors. I used Auslogics Defragmentation and PerfectDisk 11 to analyze disk for any fragmentation even though it contained no data yet. No fragmentation.
HDTune Pro indicates average transfer rate (read) is 51MB/s. I tried the write test but HDTune informed me I'd have to delete all partitions to do that.
So, what gives? 1MB/s is painfully slow! It used to be faster.
At one point in the past I backed-up my entire drive on my rickety (1GHz AMD CPU) laptop to this same drive at much faster rates. I don't think it's my system slowing it down.
Thank you!
