In this guide, we will reveal some of the possible causes that might cause the Smart LBA error and after that, we will provide some possible repair methods that you can try to fix the problem.

The error message now tells us that a UNC error has occurred with this LBA. UNC is definitely an abbreviation of UNCorrectable which means that data read after the disk was corrupted prior to this LBA and could not be repaired must be corrected. In other words, its ECC data plus data is shuffled again.

What does error UNC at LBA mean?
While this section sometimes shows the contents of specific subscriptions at the time the error occurs, the interesting part is that you can see that the description of the error Error: UNC in LBA implies 0x01963300 = 26620672. The LBA is located at a logical block address, i.e. several logical addresses on the packet disk.

What is LBA in hard disk?
The Logical Block Approach (LBA) is a generalA scheme used to locate data locks stored on computer storage devices, usually secondary storage systems such as hard drives.
I have a 300 GB WD IDE drive (300069052416 bytes, 586072368 sectors). Although no other software shows the SMART error, *SMART Utility* actually tells me the error.

It reports that there are 23 errors in total, but the last error messages were 675+ hours ago. There are 23 reports Waiting, seven removed and 7 Bad sectors redistributed.
What does a SMART error indicate?
CLEVER. Failure is a prediction that an analytical test will soon fail. The program will report an error if S.M.A.R.T. threshold has been reached.
The reader will then display 17819 +Power On Hours+. Previously, when this number was between 10515 and 13931, all five tests returned *LBA of the first error* 506133194. From time 14231 until now 12, all 13 tests returned +LBA of the first error+ between 548453258 and the result was 5 48453380. The first error was 456051244 at 17094 hours.
Do these persistently high values for +LBA First Error+ mean that the problem is only with the disk area within the nominal range, and not with the program? If so, then I can only consider the third volume of the three problematic in production, copy its contents from postman, and possibly create a new, smaller third volume. Of course, I will use this reader, especially the third volume, for some indispensability.
I should mention what the experts say, I bought this drive many years ago and maybe because I’m naive about it I usually have a low level format! Also, the disk is permanently partitioned into MBR even though all volumes are HFS+! (I meant that you can make the drive bootable, butI was in the dark all the time.)

What is LBA error?
LBA stands for Logical Block Addressing. In this case, I think it’s just another, perhaps more scientifically accurate, way of referring to a blatant “bad sector”. Unless your Hard Fire is very old, your operating system’s file engine probably didn’t know something happened.

What is an LBA error on a hard drive?
Technically, LBA refers to bad sectors, which are more or less specific bugs that block a read/write program on a disk sector. Therefore, this page describes some practical ideas on how to deal with a hard drive that is not working properly because it is associated with an LBA error, as well as important points on how to competently capture data from these drives.
