WD Internal Hard Drives and Solid State Drives
Impo
rtant:
Special handling is required to protect hard drives from damage.
Hard drives can be damaged by excessive physical force or from Electrostatic
Discharge (ESD). For more information on how to avoid ESD damage. Please
see Answer ID 1486: How to properly handle Western Digital internal hard
drives for more information.
Internal drives should automatically be seen by the system.
If the drive is not seen, follow the solutions below to assist in troubleshooting the drive. If the
drive does not power on, or is not spinning, the unit could be damaged.
macOS Update
Run App Store and check Updates to ensure your computer is up to date
System Information
Check if drive is seen in System Information
1. Click the spyglass Icon
2. Type System Profiler
3. Click SATA/SATA Express to view internal SATA connected drives
4. If the drive still cannot be seen by the macOS, please check the drive for damage. For
assistance, please see Answer ID 14920: How to check if a WD drive is damaged or
defective
Disk Utility
Check if the drive is seen in Disk Utility
Operating System and BIOS Limitations:
Computer operating systems and system BIOSs have separate limitations that are related to
specific drive capacities. The capacity points that can affect how your operating system and
system BIOS support your drive are 137GB, 32GB, and 8.4GB. Below is a quick reference chart
that you may use as a guide to determine the drive capacity supported by your BIOS.
BIOS Dates prior to May not support drives larger than
Aug 1994 528MB
Feb 1996 2.1GB
Jan 1998 8.4GB
Jun 1999 32GB
A brief description of each limitation appears below:
137GB (128GB binary) Barrier:
On many systems, the IDE/ATA interface uses a 28-bit addressing which cannot recognize more
than 137GB of storage. To overcome this capacity barrier, drives higher than this capacity have
adopted a 48-bit addressing system which can be supported in newer computer systems with
updated controller chips, BIOS codes, and operating system drivers (refer to your system
documentation for more details). If your system does not support drives of this size, you still
have a few options.
Solution 1:
You will need to purchase a controller card in order to overcome the BIOS limitations you are
encountering.
Solution 2:
If the BIOS of your motherboard or controller card supports the drive but Windows does not, see
Answer ID 928: Full capacity of PATA (EIDE) drives larger than 137 GB (128 GB binary) is not
recognized in Windows XP and 2000.
32GB Barrier:
Some BIOSs released before June 1999 stall with drives larger than 32GB. If you are
installing a drive larger than 32GB and your system stalls before floppy or drive boot can take
place, you may have a system BIOS that is incompatible with larger drives. The solutions below
should be followed only if your system stalls when adding a drive larger than 32GB.
Solution :
Contact your system or motherboard manufacturer for a BIOS upgrade or use an EIDE controller
card.
8.4GB Barrier:
There is an 8.4GB drive limitation on some traditional system BIOSs. To access the full capacity
of 8.4GB and larger drives, your system BIOS must support extended BIOS functions, and your
operating system must recognize extended BIOS functions. It is difficult to determine if your
system BIOS supports 8.4GB or larger drives. Please contact your system or motherboard
manufacturer for this information.
