ID Attribute Name Description Rational
196 Reallocation
Event Count
Tracks the total number of reallocated
Flash blocks.
Normalized Equation:
Count = 100 - (100* RBC / MRB)
RBC = RetiredBlockCount = Number
of retired blocks.
MRB = MinimumReqBlocks =
Minimum number of reserve blocks
available for contoller use. This value is
set at factory configuration time.
Normalized Value Range:
Best = 100
Worst = 0
Raw Usage:
[3-0] : Retired block count
[6-4] : None (0x00)
The normalized equation for this
attribute decrements as blocks
are retired and the reserve
(over-provisioned) block count is
decremented. (Note that all
blocks, including reserve blocks,
are in service at all times;
reserve blocks constitute Flash
memory space over and above
the drive’s logical capacity.)
As defined, this attribute is
identical to the Retired Block
Count attribute (#5).
