When I try to connect my external hard drive to the PC, it doesn't show up in My Computer. But in Disk Management, there is a Disk 1 that has a black bar at top instead of blue, showing "Unknown, not initialized" on the side and "Unallocated" under the bar. Also, when I open Disk Management it offers to initialize my disk, but I fear that would erase my data. How would I get my computer to read the disk and recover my data?
Disk unknown, not initialized is one of the most common hard disk errors that annoy various users. It usually shows as "Unknown, not initialized" in Disk Management. When encounter this issue, you can't use the unknown, not initialized hard disk or access data stored on it. You may think that getting into the disk unknown not initialized problem means you have lost all data forever.
But actually, that's not true. This passage will tell you the possible causes of unknown, not initialized hard disk, and offer you the best data recovery software to recover data from not initialized hard disk.
Initializing a hard disk basically means to assign a new Master Boot Record to the disk, to make sure it is available for the Operating System, and to bring it into working condition. But initializing a hard disk will erase data saved on it. So if you have any data on the not initialized disk that you don't want to lose, you should never initialize it.
In general, disk not initialized problem is mainly caused by corrupted Master Boot Record, partition loss, bad sectors, and virus attack.
When your hard disk becomes unknown, not initialized, you can firstly open Disk Management to check whether it shows disk capacity. If the uninitialized disk shows disk capacity, it means the hard disk can still be recognized properly by the Operating System. Under that condition, the not initialized problem is very possible to be caused by lost partition or corrupted MBR. You can recover data from not initialized hard disk with data recovery freeware.
If the uninitialized disk doesn't show disk capacity, maybe it has certain hardware problem and it's less likely for you to get lost data back with data recovery freeware. So you should send the not initialized hard disk to a local data recovery company for help.
