YES - The drive has failed and needs to be replaced. Other symptoms generally associated
with clicking include:
a) The Auto-Detect feature in the BIOS does not detect a drive.
b) FDISK does not report a drive present even if the drive's parameters are entered
manually.
In these cases, refer to our product support Web site at support.wdc.com to obtain an
RMA (Return Material Authorization).
NO - A faulty cable is a likely cause. Replace the cable to see if this resolves the issue. If
this makes no difference, the drive has most likely experienced some form of data
corruption, possibly a virus. In this case the Auto-Detect will generally still detect the
drive and FDISK will also report a drive present. Run the Data Lifeguard Diagnostic Tool
from a clean (virus free) write-protected floppy and test the drive. If the drive does not
fail, then the Write Zeros option may be needed to remove all software from the drive.
Unfortunately, all data on the drive will be lost.
I installed a large drive into an older computer, which does not see the
drive's full capacity. What happened?
If the system only recognizes 2.1 GB, 8.4 GB, 32 GB, 64 GB, or 137 GB of the hard drive or
something significantly less than the actual capacity of the hard drive, your system BIOS may
not support the entire hard drive capacity. Here are some possible solutions:
1. Check with the system or motherboard manufacturer for an available BIOS upgrade.
2. Purchase an Ultra ATA controller card. The controller card has two benefits. It will have
its own BIOS to support the drive and enable the higher transfer rates the drive is capable
of attaining. Western Digital's Online Store at store.wdc.com has a complete selection of
Ultra ATA controller cards that allow you to access the full capacity of the hard drive and
use the higher transfer rates.
3. Use our Data Lifeguard Tools CD to set up the drive. The tools will install an overlay on
the drive to support its full capacity. An overlay is a program that installs on the boot
sector of your hard drive and enables full access of your hard drive's capacity.
When installing a drive larger than 64 GB in Windows 98SE, FDISK/FORMAT
shows either the wrong or incomplete capacity. Why?
Microsoft Windows 98SE has a limitation that incorrectly displays the capacity for drives
larger than 64 GB. This limitation is not the result of data loss. The partitioning utility
FDISK and the formatting utility FORMAT will incorrectly show the capacity of the drive as
minus 64 GB. For example, if the drive is 80 GB, the capacity is shown as 16 GB. Microsoft
has acknowledged this issue and has released a fix for FDISK.
Also, depending on the particular utility used, the capacity of the hard drive can be reported
in either decimal gigabytes, where 1 GB = 1,000,000,000 bytes or in binary gigabytes where 1
GB = 1,073,741,824 bytes. FDISK reports a drive's capacity in binary gigabytes. For example,
a Western Digital 200 GB hard drive's capacity will be reported as approximately 186 binary
gigabytes.
Note: If Data Lifeguard Tools is used to partition and format the drive, no fixes are
required. Make sure you are using Data Lifeguard Tools version 11.0 or above.
