I've been experiencing random issues in accessing a particular disk - sometimes Finder will hang and not respond when accessing the disk or some directory in it. Sometimes the system just won't shutdown and has to be powered down. (This disk does not have the OS on it.)
Today, when I ran a
find command, I got an "Input/output error":
bash-3.2$ find /Volumes/Backup/ -name mega*.* -print find: /Volumes/Backup/ID/Other data: Input/output error find: /Volumes/Backup/ID/vCards: Input/output error find: /Volumes/Backup/Bills/Ike: Input/output error [.... etc.]
So I ran
dmesg and noticed the following:
SATA WARNING: Enable Drive PHY PM failed SATA WARNING: Set drive APM level failed disk0s2: I/O error. [Repeats the same 5 times again]
- What do the SATA warning and error mean - hard disk failure or damaged SATA cable?
- I was searching for a file on Volume "Backup" (which is
disk1s2), but dmesg is showing warning / errors only for
disk0s2(they are on 2 different drives) - are they somehow related to the
- Any other suggestions to pin-point the exact cause of failure?
