Recently I started to get I/O errors when I'm verifying the discs. My I/o error is: ScsiStatus: 0x02 interpretation: check condition CDB: 28 00 00 22 34 C0 00 00 01 00 Interpretation: Read (10) - Sector: 2241728 Sense Area: F0 00 03 00 22 34 C0 0E 00 00 00 00 11 05 00 00 00 00 76 14 00 00 Interpretation: L-EC Uncorrectable Error Why does this show up and what could I do to solve this?
