One should so remember that the gluing on the housing of accumulator can not correspond to the real type of the model: on accumulators U10 there can be the gluing with name U8 and vice versa.
Accumulators U8 and V8 are identical with respect to capacity and zonal distribution, but razlichayuts of 4 of those established on the pay by the microcircuit of servodekodera.
Accumulator U10 has another zonal distribution and, because of this, great capacity.
In other respects the procedure of the repair of accumulators practically coincides; therefore one general utility is realized for all three models.
Special features of testing accumulators Seagate U8/.V8/.U10
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. Firm herself Seagate achieves testing accumulators with the aid of the special version of microprogram, loaded before the plant testing into flesh - PZU of nakopitel 4. After the end of testing microprogram into flesh - PZU they substitute by the user version, which does not have the commands of access to the physical surface.
Because of this, in the utilities the testing is led via access to surface only along the logical coordinates of the sectors, whose conversion into the the physical koo of rdinaty achieves accumulator itself.
Sequence of testing the surface
For accumulators U8/.V8/.U10 to formati rovaniyem of 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 the password established by utility from it.
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.
