I have seen several causes for this; three of the most common are: 1.) A failing disk; run 'smartctl -a' and see what SMART tells you about the disk's health;
SMART overall-health self-assessment test result: PASSED
But the report does contain records of errors, eg.:
Error 5 occurred at disk power-on lifetime: 18734 hours (780 days + 14 hours) When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were: ER ST SC SN CL CH DH -- -- -- -- -- -- -- 40 51 03 0d 13 ac e0 Error: UNC 3 sectors at LBA = 0x00ac130d = 11277069
3.) A corrupted filesystem that has linkages outside the drive's boundaries; if the drive tries to seek past the end of the disk you get this. The LBA numbers you have would seem to rule this out, but you didn't say how big the disk was.
It's a 36G disk.
In short, an UncorrectableError is exactly what it says it is; it couldn't read a sector it tried to read.
Thanks. I'll probably replace the disk.
