im having similar errors


however, my hard drive is formatted for osx journaled. i never hook it up to a pc. and its worked fine for a year or two, and just now will not let me write. the disk info says i can read and write, from all accounts. so i know its not the file system format and i know its not because its write protected. it also has around 300gb free on it. there is no reason why i shouldnt be able to drag and drop files into this drive. all of the ntfs software (3g AND he paid version) doesnt do anything or recognize the drive. however the drive mounts, because its on my desktop and i can browse through it. this is bizarre and frustrating. any ideas?


ive also tried connecting it via firewire and usb 2.0 and no difference.

Another case of "haunted hard drive syndrome" 😊




junky 50 cent SATA bridge/card in an external HD


External HD are very easy to diagnose. Bad USB cable (on commercial sold USB drives) almost doesn’t exist anymore.


While these bridge cards are better than they used to be, theyre still insanely unreliable.


There are literally probably MORE than 100,000 perfect external hard drives out there thrown away every year because people assume the "hard drive is bad" when really they could crack open the HD enclosure, remove the HD and put the good HD into a new enclosure.


See this video of the SATA CARD, its at 8:55min. http://www.youtube.com/watch?v=2pS_EDsP2KI


All conventional HD external are nearly 100% like the video above.


See pic below,..a (much larger) SATA card as found inside a typical HD enclosure ($20 ebay)


This is the nasty piece pictured below causing all the "crazy" activity seen on external HD, very odd behaviour, some have called it "haunted hard drive syndrome". Random ejects, random strange vanishing of the HD , especially in mid transfer of data.


Verify this issue by hooking said HD to another USB port and diff. Mac for final verification




the card attached to the TOP of the HD plugs in, that the SATA bridge

Realize that this forum thread is several years old, so links in it are probably out of date.


The current version of NTFS 3G is available directly from Tuxera's website:
