"What can I do in order to convert external hard drive from RAW to HFS+ when there are lots of files stored on the external HDD? Every day when I boot my iMac, I will connect my external hard drive to this computer as a backup drive. Today, when I plugged my external hard drive to iMac, Mac OS cannot recognize the external HDD as an external disk. Although the external HDD is still recognized on Mac, it shows as a raw file system. Can I convert this external hard drive from RAW to HFS+ without touching any previous data?"
"I want to change RAW drive to HFS+ file system on my portable hard drive? Can somebody give me some help? It is a 3TB external hard drive that has been used for several years on my Mac computer, but it changes to RAW file system with unknown reason. I have many files stored on this external HDD, so can I recover deleted files from external hard drive after formatting?"
You are able to convert an external hard drive from RAW to HFS+ without losing data, but you should take correct measure. One of the most important points is that you cannot overwrite the external hard drive before data recovery. There is no chance to overwrite the external hard drive in principle because you are unable to write new data to the external HDD when it has RAW file system, but you still should be careful. In order to prevent you from writing new data to the external HDD, it is strongly recommended not to format the external HDD before getting back lost files. Then, you can use data recovery software to recover files off a RAW external hard drive.

After recovering all lost files from RAW external hard drive by using iCare Data Recovery, you can change file system of external hard drive from RAW to HFS+. You can also check and repair possible bad sectors on your external hard drive before formatting in order to prevent the external HDD from changing RAW file system again. Usually, you can choose to format your external hard drive from RAW to NTFS, FAT32 or HFS+ file system as you wish. As you know, HFS+ file system is only recognized on Mac OS, so you should format external hard drive on Mac OS if you need to convert it from RAW to HFS+ file system.
You have something to do in order to avoid data loss when your external HFS+ hard drive changes to RAW file system:
1. Never format the external hard drive before getting back all inaccessible data
You are unable to write even a single file to the external hard drive as long as you do not format it because it is impossible to access the drive when it converts from HFS+ to RAW. As long as there is no new data being written to the external HFS+ HDD, you can use iCare Data Recovery to recover all data.
2. Protect the external HFS+ HDD from being physically damaged
Although you cannot read or write data when external hard drive becomes RAW from HFS plus, you can continue to use this external hard drive after format it from RAW to HFS plus. However, if the external hard drive suffers any physical damage like water damage, fire damage, etc, you will lose the last chance to restore data stored on this external hard drive. iCare Data Recovery is only available for data recovery from external hard drive which is not physically damaged or overwritten.
