hello everyone ..... i bought this western digital external hdd (300 GB) a year ago and it worked fine on PC. ever since i connected it to the MAC it strtd showing USMT.TMP file corrupted and i was able to copy files only from the hdd and not to the hdd. i tried deleting the file but it said IO device error. i then tried formatting the disk using disk utility, but i am not able to as it says resource busy ..... the hdd now does not even show up on the desktop. helpppppppp as i have all my data on the hdd ......

it used to work fine on the PC but now even the pc does not read it ..... is there any way i can get it working ..... i dont find formatting the disk

First off with the external drive connected, boot from the Leopard install DVD, go to Utilities>Disk Utility and see if the external drive shows up. If so format Mac OS Extended (Journaled) and it will be right to use with your Mac.

If this does not work, try connecting to the PC and use the XP disc recovery and format in NTFS and then later connect to the Mac and reformat.
