I need to recover data from an external hard drive that has failed. I have a mac, well its a friends and he said his computer wont recognise it anymore and there is a constant flicker on the light at the front of the drive which after contacting their support line have confirmed there is a fault. He has read that if he tries to connect to a windows pc, although the drive is formatted to Mac OS, it should see it. Is this true and is there any good recovery software i can use to recover the data. I have a fully updated genuine vista premium pc. thanks.
