hi! i've been having some troubles as of today with one of my external HDs. it's a 1TB LG External HDD HXD7. it was originally mounted on a Windows PC so it used NTFS. i've been running it with Tuxera NTFS with exceptional, really rare problems. most of the time it worked fine. but today when i turned on my Mac it, i got an alert from Tuxera: i've had a somewhat similar issue before but it eventually solved itself after a while or after rebooting, or unplugging then plugging again. i don't really understand what the Tuxera alert is telling me. the USB cable has been working badly for a while, as it would often disconnect with minimum touch. i think it may have been accidentally disconnected by someone again and then when i turned on my Mac, with the drive connected, it failed to mount. the weirdest part is this: it won't mount on Mac but it appears on Disk Utility (can't repair, though); it won't mount on Windows, but i'm able to remove it safely; it runs fine when i plug it to my LG TV, and files are all there. i'm running Lion 10.7.5. any comments would help. i've googled a lot and tried some solutions but nothing seems to be working. also, any tips con freeware for data recovery is welcome. thanks!
