No, and the "uncorrectable data error" really means the disk couldn't read
a sector. It's hard to say more, IDE isn't very verbose about errors.
A retry succeded, I don't know why - maybe the drive remapped the bad sector.
It can also be other type of problems, like bad power supply, or bad cable ...
