So, long story short, I have a 750GB HD off a MacBookPro, when I plug it on my ElCapitan MBPro via external dock it doesn't appear in the finder, after a while I get the warning the disk needs to be formatted but the initialization through DiskUtility fails; I did try on another computer with Os10.7 if I recall it correct, there I have the option to change the partition table and there is a small partition which can't be either erased or removed, end of the day the format on 10.7 works but when mounting the disk on the other computer it still isn't utilizable as it is and keeps appearing after a while with the same message which says it needs to be initialized.
I gave it to a friend with a Windows computer and he said he also couldn't format it, nor through the operating system nor during the boot-up with the bios format utility or whatever is that called.
Do you have any suggestion on how to proceed to try to initialize and recover the disk in ElCapitan or whatever any other Os/Software combination?
Thank you
