tipnmo Posted September 4, 2007 Share Posted September 4, 2007 I have 2 WD 500 gb My Books. One of them has worked almost flawlessly all they way up to full capacity. The other one stops between 115-130 gigs (never made it to 130.) First I thought it was a bad drive, so i returned it, still the same issue in the same place. The little bit google did turn up suggested it was an osx problem, but i could find no solution. I ran the apple hardware diagnostic and it turned up nothing, tried all my usb ports, switched cables, both apple and guid partitioning. Tried zeroing the drive, I even tried reinstalling 10.4.10 combo update. Heres what i some times get in my system.log: Sep 4 08:39:17 Ian kernel[0]: USBF: 119909.994 AppleUSBEHCI[0x3828800]::Found a transaction past the completion deadline on bus 253, timing out! Sep 4 08:39:48 Ian kernel[0]: USBF: 119940.996 AppleUSBEHCI[0x3828800]::Found a transaction past the completion deadline on bus 253, timing out! this will usually continue tell i do something to stop it, such as shut off the drive Other times i get this in my console.log: 2007-09-03 13:10:42.108 ctask[1682] Copy Operation Error: -36 Description: ioErr. I/O error (bummers). and that is usually accompanied by a message from path finder along the lines of os x error -36, with the option to skip or stop (skipping just brings up the same message with the next file.) I do have one theory on why the first drive worked and the second does not, the first i started with some larger files but at just under 100 gigs I transfered my music collection over, I got 1 of those error 36's, skipped it, and it went on working flawlessly. On the second (bad) drive, i seem to be able to copy over small files, but anything over a meg or 2 brings up the io error. So I think it has something to do with the size of the files i am transferring, and it think if i could just break threw this 130 gig barrier i would be golden, but unfortunately i cant so i am completely out of ideas, and any help or suggestions would be greatly appreciated Link to comment https://www.insanelymac.com/forum/topic/62359-external-hard-drive-issues-just-wont-go-away/ Share on other sites More sharing options...
skyhighmac Posted September 4, 2007 Share Posted September 4, 2007 How are the drives formatted? That Could be causing a problem.

tipnmo Posted September 4, 2007 Author Share Posted September 4, 2007 via os x's disk utility as extended journaled and currently with the guid partitioning scheme Link to comment https://www.insanelymac.com/forum/topic/62359-external-hard-drive-issues-just-wont-go-away/#findComment-441736 Share on other sites More sharing options...

skyhighmac Posted September 4, 2007 Share Posted September 4, 2007 How long after you bought the bad one did you get the new one? The batch of hds thats in yours might have been bad. Could also be the hardware inside the My Book.

tipnmo Posted September 5, 2007 Author Share Posted September 5, 2007 That crossed my mind, but i got the 2 drives from different staples stores, and the second has a different power adapter and slightly different cable, so it appears that they did not come from the same batch Link to comment https://www.insanelymac.com/forum/topic/62359-external-hard-drive-issues-just-wont-go-away/#findComment-442400 Share on other sites More sharing options...
tipnmo Posted September 7, 2007 Author Share Posted September 7, 2007 well i found a work around, not a fix, and it turns out it was either my computer (MBP) or os x, which i am not sure I downloaded the lastest ubuntu distro (7.04 feisty) which has quite good HFS+ support (does not support journaling, but that can be disabled at the os x command prompt.) Ran the live cd, logged in as root (cant write to drives other wise) and copied from there (all this was done on my pc fileserver.) I can post more details if anyone is interested. However this has left me quite disappointed with apple, I should not have had to use ubuntu to bail out an os that "just works" for something that really should have just worked.

tipnmo Posted September 8, 2007 Author Share Posted September 8, 2007 SOOO frustrating, is there any reason to believe that reinstalling os x would fix the problems?,, google found a thread where someone with the same issue resolved it by reinstalling OS X Link to comment https://www.insanelymac.com/forum/topic/62359-external-hard-drive-issues-just-wont-go-away/#findComment-444387 Share on other sites More sharing options...
rezwits Posted September 12, 2007 Share Posted September 12, 2007 This is basically the same "data" you are trying to copy over right? Cause if it is then it's possible something is wrong with files/folder that the disk utilities can't pick up. That happens. But if it's different data and different tries with different stuff then I don't what to tell you. You said it wasn't FAT32. Sounds like some files are messed up from the drive you are trying to transfer from...
