When the disk shows unknown

When disk shows unknown, which means the western digital could not be recognized normally as a healthy disk, usually a healthy disk would display the following information in disk management.

  • Disk number (Disk 0, Disk 1, Disk 2...)
  • Basic, or dynamic (the property given by the Windows OS according to how your disk is set.)
  • Storage capacity (250GB, or 931GB for 1TB which is usually a few gb less than the capacity it is named...)
  • Online(healthy); Offline/Unknown(damaged)...
  • Not initialized - it's a special status for a brand new drive and as for an old used hd that means the disk is damaged
  • Partition map on the right column which shows each partition with its properties (primary, extended, storage capacities...), if it shows unallocated, or no size, the disk is damaged for some reason

MBR OR GPT

We would recommend you try MBR at first and then you can convert it to GPT later, or you may select GPT as you wish in the first step when usually GPT is more popular with more abilities for holding data and with better performances.

MBR is more accepted by third party software while GPT is less supported in the market since the later one was not all supported by software developers due to technology update delay.
