Hi guys, I'm currently on a macbook with a 1TB external hard drive connected trough a USB hub wich is connected on my macbook. The problem is, my disk, wich is partitioned in 2 (one HFS+ and one NTFS) keeps getting corrupted, recently it was my HFS+ partition, I could not repair it using the Apple's Disk utility, but was able to backup my files.

Is it synonym that my hard drive is failing? Is it because of my USB hub?

I also keep all my iTunes library on my external HD (HFS+ partition), and did a lot of transfer lately, adding files, removing etc. the last time, my partition got corrupted after a lot of deleted items.

If anybody has an idea of what to check first, what could cause the problem, I would appreciate it :)

Thanks!
