    I have a MacBook Pro with 10.6.4

    The external HDD is a 320GB 2.5" Samsung. Using my MacBook Pro, I formatted it to have a 250GB partition for TimeMachine, with two other partitions for Windows computers as I was traveling without my MacBook and needed to backup photos.

    I used the HDD successfully for 3 months with no problems. But when I returned and tried to put everything on my Mac, Disk Utility told me I needed to verify and repair the disk. As it wouldn't mount, I performed the tasks that DU suggested, but now I am stuck with four partitions(?) which are not readable. And now DU does not give me any options.

    See screenshots here:

    The disk spins up normally, with no abnormal noises. I suspect there were plenty of Windows viruses (as I had to use many PCs over the 3 months), but the last time I used the drive successfully, it was on a PC and I successfully transferred items onto it.
    Please could you advise on actions or further diagnostics I should do. Luckily I bought a 16GB flash drive to make a 2nd backup of photos, but there still important documents which I need to recover off the HDD.

    Have you tried connecting it to another computer? Viruses are not the issue but maybe the drive itself is busted

    I connected it to a PC, but it didn't mount. Said I first needed to format the drive before it could be used.
