Embodiment belongs to the scope of the present invention.
Core of the invention is to provide test method, device and the computer storage medium of a kind of solid state hard disk, is used for
Solid state hard disk is tested before factory, so that it is determined that the time of day of solid state hard disk.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Embodiment one
Fig. 1 is a kind of flow chart of the test method of solid state hard disk provided in an embodiment of the present invention.As shown in Figure 1, the party
Before method is applied to solid state hard disk factory, the following steps are specifically included.
S10: a data block of solid state hard disk is chosen.
S11: judge current data block first page and last page identifier whether with pre-set identifier
It is identical, if it is different, then, if identical, entering S13 into S12.
S12: label current data block is bad block, and enters S13.
S13: judging whether there are also remaining data blocks in solid state hard disk, if so, S10 is then returned to, if it is not, knot
Beam.
It should be noted that the solid state hard disk in step S10 need to be it is completely new, without any read-write wipe operate.Step
The data block chosen every time in S10 is different data block, that is to say, that in the test for the bad block for carrying out the same solid state hard disk
In the process, the selection of each data block is unduplicated.In addition, in order to choose conveniently, it can in a certain order, then such as
Fruit is to execute S10 for the first time, then current data block is exactly first data block, is judged after the result of the data block it is necessary to the
Secondary execution S10, then current data block is exactly second data block, is carried out until by each data block in solid state hard disk
The test stated.
For step S11, each data block has its identifier, need to preset (specific method of setting and
Content is identified, the present invention is not construed as limiting, and nor affects on the implementation of this programme), such as FFh, under normal circumstances, in the data block
Each page of identifier should be it is identical, in this step, in order to quickly judge, have chosen first page and last page, because
For, it is generally the case that if first page is identical with the identifier of last page, then other pages of identifier between this page two
It will not be abnormal.Because first page and last page are the same identifiers when presetting identifier, so, for step
For S11, it can be and judge whether first page and last page are identical, if it is not the same, then entering S12, if identical, enter
S13.In specific implementation, the identifier of first page and second page can all be read, then again with pre-set identifier
It is compared；The identifier for either first reading first page, which is compared with pre-set identifier, if
It is not identical, then illustrate S11 judging result be it is no, be directly entered S12, also the unnecessary identifier to last page sentenced
It is disconnected.For the former, if the data block is bad block, the time used in the judgement of the latter is shorter.In conclusion if
The first page of the current data block perhaps identifier of second page or first page and second page and pre-set identifier not phase
Together, then illustrate current data block be exactly bad block, only first page and second page identifier with pre-set identifier phase
Together, just show that current data block is not bad block, i.e., non-bad block.
The effect of step S13 is to judge whether to have carried out the judgement of bad block to all data blocks in solid state hard disk, here
Remaining data block be exactly not by bad block judgement data block.For example, passing through if carrying out the judgement of bad block in sequence
A S10-S12 is executed, then the remaining data block in solid state hard disk is exactly other data blocks in addition to current data block, so
As long as then the judging result of S13 is no, then needing to return at this point, the quantity of the data block in solid state hard disk is not less than 2
S10, that is, the judgement of bad block is carried out to next data block.
By above-mentioned steps are performed a plurality of times, all data blocks of solid state hard disk can be judged, and obtain it includes
Bad block, be capable of determining that solid state hard disk has several bad blocks with this, complete the test of bad block.
The test method of solid state hard disk provided in an embodiment of the present invention, before solid state hard disk factory, for completely new solid-state
Each data block in hard disk carries out the test of bad block, specific test method be judge current data block first page and last
Whether the identifier of page is identical as pre-set identifier, if identical, then it is assumed that and current data block is not bad block, if
It is different, then it is assumed that current data block is bad block, and marking current data block is bad block.It can be seen that this method can be in solid-state
It can determine there are how much bad blocks in solid state hard disk before hard disk factory, decide whether to go out so as to the quantity according to bad block
Factory's sale, improves the experience sense of user to a certain extent, also provides guidance foundation for subsequent production, avoids the occurrence of excessive
There are the solid state hard disks of bad block, save production cost.
