Warning
The authors warn that the use of a utility  "HDD Repair  Tool for Seagate Ux "  is permissible ONLY with accumulators  Seagate Ux.  An attempt at the application of a utility on the accumulators of other models can lead to their  irreversible spoiling!

BEFORE beginning the repair of accumulator, immediately after the start of utility, against yazatel'no it is necessary to preserve in the archive its disk moduli. In the presence of external sequential PZU –to preserve its contents.
? sequential PZU it is possible to count by means of dialogue  Actions->.Flash operations;
? disk moduli it is possible to consider posr yedstvom of dialogue  Service - > CP operations.

Look the detailed description of work with these dialogues in the appropriate divisions of documentation.

Main menu
With the pushing of the right knob of "mouse", the program issues on the screen the main menu, the hierarchy of points of which is given below:
 
The designation of the points of menu will be described below.
Testing the accumulator
General information
Upon the entering of accumulator in the repair should be verified by tester the resistance between the common wire and the power buses  of +.shchV  and  +.y2V:
? on the power bus  of +.y2V  resistance must be about  70  kљ;
? on the power bus  of +.shchV  resistance must be about  2  kљ.

We further connect accumulator to pay  HRT  and start utility. Accumulator nekoto cluster by delay must leave into the readiness - in the field of the "window of light-emitting diodes" must ostat's 4 "burn" only flags  DRDY  and  DSC.

The work of utility with the accumulators, which do not emerge into the readiness on  Ata- to interface, is impossible! This is caused by the limitations of the microprogram of the very of nakopitel 4.

After the start of utility will appear the window, in which will be represented kha rakteristiki of accumulator.
 
Focus attention, that the complete name of the microprogram of accumulator, printed out in field  Family code,  contains  15  numbers, grouped into  2  groups of  3 yekh and  4 yekh fields respectively. The first group  –the version of overlay part, the second group - version of contained PZU.  However, gluing on the housing of accumulator contains only the first two fields of the version of contained PZU in the line  "Firmware".
Special features of testing accumulators  Seagate Ux
Unfortunately, all accumulators  Seagate U for a series do not permit implementation of access through  Ata- interface to the surface of disk directly in the physical coordinates. Because of this, in the utilities the testing is led via access to surface  only  along the logical coordinates of the sectors, p reobrazovaniye of which into the physical coordinates achieves accumulator itself.
Sequence of testing the surface
For accumulators Ux formatting logical surface is the record into the formatiruyemuyu region of any data through ATA- interface (on the logical coordinates).
Imperatively one should conduct formatting accumulator, also, before beginning, strictly, the search for defects. The preliminary formatting of surface is necessary for the exception of interpretation as  the physical defects  of sectors with the incorrect  Comte by the rolled sum  and the sectors with the incorrect  number of sector  in his title.
For accelerating formatting  entire  surface we advise to use a point of menu  Actions - > Quick Clear.
Point  "Quick Clear"  in the utility is realized with the aid of  Ata- command  Security Erase Unit;  therefore during the random interruption of the rapid erasure of accumulator will have to remove that established from it by utility password.

The possibility of checking the surface on the logical coordinates only requires the required formatting of surface after the sequential concealment of defects in  P -.list.  Otherwise, from the now concealed into  P -.list  defect to the end of the physical track, on the coto bark rum the defect of nakhodils 4, for all sectors during an attempt at reading will be returned error  UNC.  This by the noncoincidence of the numbers of these sectors in their titles with the numbers, coto bark rye caused expects the translator of accumulator. Formatting will lead to the copying Nome ditch in the titles at the correct values.

One should produce testing the surface of that newly entered of nakopitel 4 in the following sequence:
34)  ****->.Bufer – testing the data bus  Ata- interface.
3 5)  Actions - > Quick Clear – for eliminating  Unc- the errors, not caused by the physical surface damage.
36) Defectlist - > G -.list - > Clear on disk – the removal of the acquired defects (in the process of operation).
37) **** - > Verify forward(.reverse) -  the rough testing of surface by verification. Obtained defects during  the tests  not to hide,  but to accumulate in the list.
3 8)  Recovery -  concealment of the obtained defects  by united list  into  P -.list.
39) **** - > Write forward – formatting surface after the concealment of defects obtained in  verify- tests.  Its number for the subsequent testing of the errors of the translator of accumulator –so into each sector will be brought in.
40) ****->.Read+.Check – testing surface by reading and checking the translator of accumulator.
41) ****->.Defectoscope – testing (thinner) surface with the installation of the maximum time of the response of surface.
42) Recovery -  the concealment of the obtained defects  by united list  into  P -.list.
43) Actions ->.Tsuichk Clear – formatting surface after the concealment of defects in  P -.list.
44) ****->.Defectoscope – the output testing of surface.

It is possible to repeat any **** 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 ****":
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 ****".  But in this case the concealment of the list of defects the **** 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 ****
"Read+.Check",  that requires the required preliminary prescribing of sectors in the ****  "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.

But one should remember that:
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 **** 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:
 
Field  LBA count  contains the volume of accumulator in  LBA.  Fields  Size  in this
