Вчера Current_Pending_Sector=2, сегодня уже 6. Винт работает в составе raid1, mdadm. Иногда вылазит вот такое:

Dec 19 20:44:49 router ata1.00: limiting speed to UDMA/100:PIO4
ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen
ata1.00: cmd c8/00:08:47:02:b0/00:00:00:00:00/e4 tag 0 dma 4096 in

ata1.00: status: { DRDY }
ata1: soft resetting link
ata1.00: configured for UDMA/100
ata1: EH complete

И возрастает счетчик UDMA_CRC_Error_Count. Может возможно поменять винт по гарантии?
