Replacing and Upgrading Hard Drives
Q4:
A4:
What should I do if I need to replace a defective hard drive?
1. To minimize the risk of losing data, make it a practice to keep a spare hard drive
of the same brand and model for the next three to five years. Always restock
your spare inventory with new hard drive(s) of the same model whenever a
defective hard drive is replaced.
2. If your replacement drives are the same manufacturer as the original drives but
are a larger capacity, place the surviving drive in the upper bay where it will be
designated as the source drive. Boot the PC from the upper bay source drive.
When the operating system is ready to serve, insert the replacement drive into
lower bay. The disk auto rebuild procedure will now start. If it fails to start, switch
the front panel operation mode switch from Single to Dual.
For normal operation, always put the smaller capacity drive in upper bay and
larger capacity drive in lower bay. Never place the larger capacity drive in the
upper bay.
Tip: Label each tray with the disk capacity, brand, and model for future reference.
3. CASE STUDY:
●
Company ABC uses two Seagate Family ST3250823AS (Seagate250GB)
drives on one ARAID disk array.
●
Company ABC should keep an inventory of spare ST3250823AS drives.
●
Company ABC experiences a Seagate250GB disk crash and has no more
ST3250823AS to replace. Instead a new Seagate Family ST3300622AS
(Seagate250GB) is available for replacement. For daily operation, the smaller
drive, the Seagate250GB, needs to be put in upper bay and the larger drive,
the Seagate300GB, must be put in the Lower Bay as a mirrored couple.
In this scenario, the mirror couple of Seag Seagate300GB, its
effective capacity is 250GB. RAID 1 disk array capacity is always defined by
the capacity of the smaller drive.
●
For Windows User ONLY:
If at some later point the 2nd drive Seagate250GB malfunctions and the
Seagate300GB is the surviving drive, you can enlarge the Seagate300GB’s
partition size from 250GB to 300GB by using a third party’s program, such as
Symantec's Ghost or Partition Magic. Then mirror it to another Seagate300GB
and gather a 300GB disk capacity.
