lavetta Level 1 Level 1

A little while ago I backed up some files on my iMac to an external hard drive (formatted in the Mac format). These were primarily office documents (PDF files, Microsoft Office) and some photos. The documents had orignally been copied to my iMac from a PC (via USB), whilst the photos were imported directly to the iMac. Having brought a MacBook Pro recently, I've been attempting to copy the data over. Unfortunately, I keep getting error code 36 when it attempts to copy the files over. I've tried skipping some of the files it gets stuck on, but it keeps finding more. This also happens when I am just trying to copy over a folder of photos. Another unusual thing that I noticed is that when I try to copy a folder containing just under 300 files, when it attempts to copy it says it is trying to write 1,500+ files... which I don't quite understand.

 

I've run the disk utility tool to check the hard drive, but it says it's fine. Prior to copying the data over to the external hard drive in the first place, it had been freshly formatted. Unfortunately, since this was the backup disk, I kinda need to save these files!

 

Does anyone know of any solutions out there that could help?


MacBook Pro (15-inch, Mid 2012), Mac OS X (10.7.4)

The external drive is failing, or else you have a bad cable or a bad logic board.

    This doesn't help unfortunately, as the data is only on the external HDD - I'm trying to get the data from there on to my MacBook. Disk utilty thinks that the external HDD is fine. Does anyone know of a way to recover the data?

    Launch the Console application in any of the following ways:

     

    Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.

     

    Click the Clear Display icon in the toolbar. Try the action again. Post any messages that appear in the Console window – the text, please, not a screenshot.

    Should I do this after trying to copy the files over?

    Open the log, then try copying. Capture some messages -- a reasonable number, not thousands. Post.

    Here's what comes up on the console after I plug in the external hard drive and attempt to copy over some of the files:

    The external drive is failing, or else you have a bad cable or a bad logic board.

  • lavetta Level 1 Level 1

    OK... I just tried again with a different cable, and I am getting the same result. The MacBook is brand new, so I would assume that the logic board is fine. I also managed to transfer data from another external hard drive just fine with this second cable, so it sounds like the issue is with the external drive...

     

    Are there any options to recovering the data (aside from going to an external data recovery service)? Unfortunatley this external hard drive was my back... (lesson learnt!).

    Was the other drive a Western Digital, too? For some reason, WD drives just don't seem to play nice with Mac's sometimes.

    The drive causing problems is a 500 Gb Western Digital. I have a LaCie drive that seems to be working fine.

     

    Good to know in the future though that Western Digital drives don't always agree with Macs...

    lavetta,

     

    I don't know what it is about WD drives - everyone here seems to have problems with them, though. For externals, I have LaCie and a couple of Hitachi G-Drives. I would also recommend anything from LaCie. I really like the G-Drives - lots of different interfaces. I'm using two of them and an old (6 year old!) LaCie via Firewire 800 with no problems. Just sell that WD and 'upgrade' to a brand that's known to work with Mac's.

    You may be able to salvage the drive mechanism by removing it from the enclosure and installing it in another one, or in a drive dock. Otherwise, you're in a data-recovery situation. I have no experience with that and can't help.
