بيان لليدات ( لمبات ) ال WDR
مقاله عن لمبات البرنامج WDR  BSY – drive busy DRDY – Drive ready to accept commands ERR - The Last Result was an Error DREQ - exchange data with host UNCR- Uncorrectable Error WRFT - Write Fault IDNF- Sector ID Not Found . If the sector that holds this information is corrupt there is no way for the hard drive to locate this sector and it will return the result IDNF. AMNF- Address Marker Not Found . This is similar to the IDNF but relates to the data. If there is an error and this marker is corrupt then the data for this sector cannot be located. The data in this area is 512 bytes of user data ABRT- Command Aborted. - is an abort error and it will discontinue trying to read that block TONF - Track 0 not found ECC is that there is a problem reading from ECC and it does not match. ECC is used to check the integrity of the data being read. When the data is read the drive calculates the ECC and compares. If there is an error the drive will retry until it cannot get a correct result and then will return the UNCR error UNCR-Uncorrectable Error WRFT - Write Fault Heads use servo info to identify the correct track. Then the heads read each and every sector ID block to determine if it is the correct one using the “translator.” If the ID field is corrupt there is nothing to identify what the data is looking for and it will flag the IDNF (ID Not Found) error. If it finds the correct sector ID, the heads then would read the Address Marker for the 512 bytes of data that go with that location. If this info is corrupt then the heads cannot locate the beginning of the data and will return the AMNF (Address Marker Not Found) error. An AMNF error means that the ID Marker info WAS found but that the data in the markers that goes with that address were NOT found, again losing 512 bytes of user data تحياتي للجميع. |
