External HDD HFS+ Disk Shows 0 Byte Space

"Why does an external HDD HFS+ disk shows 0 byte space when I check its Properties on Mac OS? It should have been a 1.5TB external HDD with more than 100GB data. Does it mean that all data has been deleted when its space shows 0 byte? But why the external HDD HFS+ disk becomes inaccessible? I want to get back the deleted files from this inaccessible external HFS+ HDD, but I do not know the solution. Can anybody tell me how to recover data when an external HDD HFS disk only has 0 byte space?"

In fact, when you find that your external hard drive shows 0 byte space and becomes inaccessible, it is impossible that its file system is still in HFS plus. Probably, the file system of your external hard drive has become RAW. RAW is an error file system that is unable to be recognized by Mac or Windows OS, so your external hard drive will show 0 byte space when its file system changes to RAW.

In other words, you can convert external hard drive from RAW to HFS+ file system by formatting.

Therefore, you cannot format the RAW external hard drive if you want to recover all inaccessible data. iCare Data Recovery allows you to recover different kinds of files from external hard drive such as Seagate, Western Digital, Toshiba, Maxtor, Transcend, Kingston, etc.
