Sorry if this is in the wrong section. I tried searching first, and found a similar thread, but it had no answer. ----------------------- I have a Western Digital 250 GB USB External Hard Drive that no longer seems to work. When I hook the external HD up, I get an error prompt, 'The disc you inserted was not readable by this computer'. The HD icon also does not seem to appear anywhere on my iMac. I have tried using disc utility to repair the drive, as it does recognize that the drive is there, however I get the following error message: "filesystem verify or repair failed." I am looking to hopefully salvage my data that's on the external HD, but if it's gone for good, is it possible that I can wipe the drive clean and regain its functionality? Bare in mind that I do not know anything about external HDs, reformatting or anything like that. Also, a friend of mine has a copy of Disc Warrior 4, so I possibly have that at my disposal as well (no idea how to use it though). Suggestions?
