ata 3 error whenever i boot linux


whenever i boot linux it shows this error continuously:-

ata3:exception Emask 0x10 SAct 0X0 SErr 0x4000000 action 0xe frozen

ata3 : irq_stat 0x00000040, connection status changed

ata3 : SError : {DevExch}

Have you tried this disk in a different PC?
Maybe you have a faulty disk (or a faulty SATA connection).

You could try SMART to get some stats, but the disk is likely on its way out.
Anything more than a few dozen bad clusters means its going to fail soon.

i tried SMART and found just 1 bad sector in the disk which was removed by low level formatting

The bad sector was not necessarily removed by the low level format - it may have been just added to the list of permanently bad sectors and allocated a "spare" sector. This is OK, but you only have a small number of substitute sectors provided for this purpose on the disk.

Are you still getting the dmesg errors?
If not, try running some kind of disk test or just writing large chunks of data to it.
