Apologies if this isn't really Boot Camp related but I thought this the nearest fit to ask.... I'm back to using my Windows 7 machine while my Macbook Pro is in repair. I have connected my 2TB external drive to it which is formatted in HFS+. Last night, my Windows machine read all of the HFS+ files perfectly - I spent all night watching videos from the hard drive. Today, however, when I connected the external hard drive I was given the error message 'The disk structure is corrupted and unreadable.' Any ideas why my machine would read my Mac hard disk last night but not today??
