pasti bingung itu apaan ata4? itu hardisk yang mana (kalo pake beberapa hardisk yang pasti makin bingung). Pake lshw ngga nemu juga
$ lshw -class disk -short H/W path Device Class Description ================================================= /0/1/0.0.0 /dev/sda disk 2TB WDC WD20EZRX-00D /0/2/0.0.0 /dev/sdb disk 2TB ST2000DM001-1CH1 /0/3/0.0.0 /dev/sdc disk 2TB WDC WD20EZRX-00D /0/5/0.0.0 /dev/sdd disk 256GB KingFast
Solusi
Biar ketauan itu hardisk yang mana parsing data dmesg
dmesg | grep ata4 | head -10
output perintah diatas
[ 1.511420] ata4: SATA max UDMA/133 abar m1024@0xfcfffc00 port 0xfcfffd80 irq 22 [ 1.971020] ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 1.971807] ata4.00: ATA-9: ST2000DM001-1CH164, CC27, max UDMA/133 [ 1.971809] ata4.00: 3907029168 sectors, multi 16: LBA48 NCQ (depth 31/32), AA [ 1.972649] ata4.00: configured for UDMA/133 [ 1737.793400] ata4.00: exception Emask 0x10 SAct 0x60000 SErr 0x40d0202 action 0xe frozen [ 1737.793623] ata4.00: irq_stat 0x00000040, connection status changed [ 1737.793740] ata4: SError: { RecovComm Persist PHYRdyChg CommWake 10B8B DevExch } [ 1737.793959] ata4.00: failed command: READ FPDMA QUEUED [ 1737.794077] ata4.00: cmd 60/08:88:b8:8a:c3/00:00:ab:00:00/40 tag 17 ncq 4096 in
baris ata4.00: ATA-9: ST2000DM001-1CH164, CC27, max UDMA/133 merupakan model dari hardisk yang digunakan, jadi bisa di bandingkan hasilnya dengan hasil perintah lshw -class disk -short, jadi hasilnya
/0/2/0.0.0 /dev/sdb disk 2TB ST2000DM001-1CH1
