So I currently using a 3 TB Western Digital Hard Drive that has an interesting issue. Every time I turn off the hard drive (after properly ejecting it) I gain some sort of data loss (small data loss like on a album of songs something album art is missing or a few songs are corrupted). But when I keep the hard drive on, (and properly ejecting it) the data isn't lost. Is this typical behavior for a hard drive or is there something wrong with it (whether hardware related or software). It's formatted as Mac OS Extended (Case-sensitive) and on a Rosewill enclosure. I did reformat from NTFS in order for it to work with iTunes. I have tried erasing and reformatting with same results. My other hard drive does not have this issue.
