44) Test->.Defectoscope – the output testing of surface.

It is possible to repeat any test repeatedly if necessary, but one should remember that  after any placement of defect into  P -.list  surface of accumulator this defective sector one should otformatirovat' anew.

From that stated above follow the following installations of the parameters of window  "Logical test":
7) or flag  "Try to recovery"  must be discarded, and the moment of the concealment of the list
defects it will be selected by user itself on the pushing  of knob  "Recovery"  in
the dialogue of the result  of testing.
8) or flag  "Try to recovery"  must be mounted, then in  the list  "Recovery"  it is necessary to select the moment of concealment  "After last test".  But in this case the concealment of the list of defects the test of record must directly follow!

It is possible to use the version of the concealment of defects not in  P -.list,  but in  G -.list.  Then to formati rovaniye of surface after the concealed defective sector is not required, and tests pove of rkhnosti can be carried out in any order. Exception will compose only the test
"Read+.Check",  that requires the required preliminary prescribing of sectors in the test  "Write forward(.reverse)".
The concealment of defective sectors in G -.list, in contrast to the concealment in P -.list, does not shift the logical surface of disk; therefore data of pol'zovatel 4 and their arrangement relative to the beginning of disk  in all remaining sectors  will be preserved. This it is possible to use if necessary to hide certain stake - in defects during the restoration of data from the accumulator.

The selection of the sheet, into which they hide defect, is produced in the window of tuning testirovani 4 in the list  "Recovery type":
? "Upload" – to hide in  P -.list;
? "One by one" – to hide in  G -.list.

16) the concealment of sector in  G -.list  is produced more slowly than the concealment of sector in  P -.list;
17) in  G -.list  it is possible to hide not more than  800  defects.
18) in  G -.list  it is not possible to hide some fatal surface defects, nap Reamer, caused by the spoiling of servometok on this track;
19) concealment in  G -.list  leads to the subsequent delay of linear reading / of record of data in this place for surface, which will be well noticeable on the test of flaw detector;
20) all concealments in  G -.list  are mapped into  Smart- counters of the acquired defects, whose nontrivial state can hinder subsequent sale of the repaired accumulator.

Therefore concealment in  G -.list  during the repair of accumulator is not recommended.
Correcting the passport
If necessary of changing the name accumulator, or its logical razme of the Ra, it is possible to use the procedure of a change in the specifications of accumulator. In order to perform this operation, it is necessary to select the point of menu  Service->.Special Area - > Change Passport.  In this case on the screen the following dialogue will be given out:
