ls: reading directory /var/share/movies/: Input/output error

Hello,

I get the following error when using the ls-command

Code: Select all

ls: reading directory /var/share/movies/: Input/output error

Anyone know what it means?

Sounds like you have a read problem (hardware problem).

Try unmounting and remounting your drive.

You can also check dmesg for more info.

Unmounted the drive and checked it with fdisk:

Code: Select all

# fdisk /dev/sdd
fdisk: cannot open /dev/sdd: Input/output error

Dmesg gives the following:

Code: Select all

dmesg | grep sdd
[1530841.170290] sd 5:0:0:0: [sdd] Unhandled error code
[1530841.170293] sd 5:0:0:0: [sdd]

Doesn't sound good...

the drive is bad,
but how do I know in linux what drive is connected to what sata-port?

I have 6 drives,
the bad one is /dev/sdd

In the latest version of linux (at least from kernel 3.2)
you can get a list of hard disk id's in /dev/disk/by-id/

Code: Select all

ls -l /dev/disk/by-id/
lrwxrwxrwx 1 root root  9 Aug 27 20:47 scsi-SATA_SAMSUNG_HD103SJS246J9GB303707 -> ../../sdb
lrwxrwxrwx 1 root root 10 Aug 27 20:47 scsi-SATA_SAMSUNG_HD103SJS246J9GB303707-part1 -> ../../sdb1
lrwxrwxrwx 1 root root 10 Aug 27 20:47 scsi-SATA_SAMSUNG_HD103SJS246J9GB303707-part2 -> ../../sdb2

it doesn't tell you which SATA port;
But it does tell you the drive id.
The same number is also printed on a label of the hard disk.

This should help you find the correct disk.
