Slow copying of files from Bricked NAS to computer via USB 3.0 to SATA

1

Unfortunately I bricked my "Western Digital MyBookLive 3TB" network hard drive. (Only had an ethernet port to access files via network)

After realising it was not going to work again, I decided to take it apart and order a USB 3.0 to SATA adapter to get my important files back.

Using a MacBook Air with 3.0 USB ports and using fuse-ext2 I am able to read access my files. I am trying to copy the files I need but there is a serious bottleneck somewhere.

Currently I am trying to copy 6GB of photos to my laptop, it has been copying for 5 hours and it has only copied 450MB so far with an estimated 2 days remaining. Here's an image

Could anyone explain anyway of making copying a bit faster, and what might be causing the snail pace transfers. I was able to copy my files over the network 100x faster (before it broke :P)!

Also I was reading somewhere that WD made the block size 64k instead of 4k... I must admit I have no idea what this means and how it might effect copying data.

Information on the exact model of the hdd and the adapter you are using. This sound more of a hardware issue then a bottleneck problem to be honest. – Ramhound – 2013-10-01T12:54:00.070

Have you considered that the drive itself is failing? Have you run WD's diagnostics against it? – Ƭᴇcʜιᴇ007 – 2013-10-01T13:07:19.293

This might be a fuse-ex2 problem. I've read similar reports. Have you tried OSXFUSE?

Do you happen to have an Anti Virus running on your Mac? (We have had a case in our workplace where Anti Virus would make their time machine backup crawls to a halt. As soon as the Anti Virus temporarily stopped / removed / disable on-access scanning - it speeds up to normal) – Darius – 2013-10-01T15:56:33.093
