Hi all

I wonder if you could offer suggestions to a problem I am facing with two external hard drives connected via USB 2 to my 5,1 mac pro. Those, one WD Black 4TB and one WD Green 3TB, host my music and both are in inxtron enclosures. Recently, the black has become completely unresponsive, along with the Finder, to the point I have to force shutdown my mac pro. On restart it shows again on the desktop but after a few minutes its its usual no-go itself. I ran both disk warrior and disk utility on it, immediately upon restart, before it starts acting, and no errors were found. This led me to believe that its enclosure is on its way out. Thus, I decided to install the drive in one of the mac pro's sata bays but upon restart (many of them) it says that the disk is unreadable and needs initialising. Launching disk utility to do repairs while the drive is in the mac pro does not help as the partition scheme appears as Master Boot Record (???) and cannot be modified (both disks are formatted as HFS+) even though SMART reports that all is OK. Putting the drive back into the enclosure, allows for the volume to mount but , alas, it becomes unresponsive after a few minutes. Any ideas would be greatly appreciated.

Thanks for your help and time!

A lot of USB and TB external drive enclosures have a non-standard way to initialise/format the drive and when you remove it from the enclosure and install internally, the data is inaccessible.

Try to backup the contents then reformat the drive if you are going to use it internally, i.e. test the WD Black on the second still working enclosure and se if you can rescue all the data.

Thanks for that! if you do not mind, are there anyUSB enclosures, to your knowledge, that format drives the standard way, so as to avoid problems in the future?

Thanks!

Sorry, but it's extremely difficult to suggest one, more than once I bought one to test, then two weeks later I bought more and to my dismay it's totally different internally.

No worries; thanks a million for your help!
