Shortly after connecting a new mouse my MacBook Pro (OS X 10.5.5) started slowing down before finally crashing and then wouldn't proceed past the blue startup screen. Trying to start in safe mode wouldn't work either. I tried to repair the HD from Disk Utility using the install DVD but I get the following: Incorrect number of thread records Invalid volume file count Should be 651985 instead of 651982 This happened 3 times and then it said that the repair failed. Starting in verbose mode gives me 'I/O error'. Is there anything else I can try before erasing the HD? I don't have a back-up of my most recent files. Will creating an image of the disk on an external drive help me get these or is it already too late? Is there any other way of getting to these files? I would be extremely grateful for any help anyone can give me. I have some files on that computer that I need to get at ASAP.
