Here are some simple methods that can help solve the problem of reading the Debian directory. I / O error.

I wanted to share my experience: With FreeBSD 10.3 I have a USB hard drive with
. established
$ sudo ntfs-3g / dev / da0s1 / media
I ran an absolute mkdir
on my hard drive to create a directory and move some game files there from nusing the mv
command. Finally, I often have the following command:

$ sudo sync
Then I used to mount the hard drive on a Linux machine with a shared kernel 4.4.0-78. Now, when I usually list the contents of the hard drive, the FreeBSD-generated site directory Jeff
is displayed with the name:
$ ls -lhrtcils: Unable to start browsing 'Jeff': I / O errortotal 20K ? D ????????? ? ! ? ? ? Jeff
Also, when I try to delete the Jeff
directory, I get the following error messages:
$ sudo rm -f -R Jeffrm: Failed to delete 'Jeff': I / O error
I wouldn’t get rid of the Jeff
directory on a Linux machine, so I used FreeBSD machines and remounted the hard drive to FreeBSD. But the ls
, cd
to rm
commands in FreeBSD cause the same I / O error. There appears to be a credible bug in the FreeBSD package
ntfs-3g
.
UPDATE
I have moved all my data from my external hard drive to my Linux computer, of course the corrupted file Jeff
could not be moved due to an E / S error. Then I reformatted the visible hard drive by zeroing the volume and checking the bad sector, for example:
$ sudo mkfs.ntfs / dev / sdb1
And then all of your backup data was moved to the outer volume. This way I lost the corrupted file referenced by Jeff
, but there were no I / O errors on my external hard drive.
The computer was working fine until this morning I learned that an I / O error occurred on the hard drive (two 4TB hard drives in RAID0 with mdadm
).
ls: display directory '.' : guilt
And another dmseg related I / O check shows that accessing my MD127 CD is causing some warnings and errors:

After doing some research, I found several articles that talked about using fsck
to fix this idea (I'm using Ubuntu 18.04).
- Ext4 file system corrupted overnight
- Ubuntu error EXT4-fs around 18.04.
I also found a person who had a What a big problem with the RAID0 hard drive (but a long time ago, since it is actually kernel 4.0.0).
My hard drive looks fine because using smartctl
reads PASSED
. And inode
seems to work as there is so much left (only 7% used in inodes).
What could be the cause of this spontaneous failure? I want to be sure because I want to know how to prevent this or be prepared for the next event.
Right now I'm actually copying the undamaged files, but I can get by without restoring fsck
.
Speed up your computer's performance now with this simple download.
In this situation, the first suggestion is to check / var / log / messages for disk-related warnings (you can see the key warnings). If you are having problems with your hard drive, try using Disk Utility to confirm. One possibility is to use smart tools. You need to enable smartool option to fix bad pads.
What is an I / O device failure? I / O drive errors are quite common.Reboot your computer.Check your cables and connections.Try another useful USB port.Run CHKDSK and SFC.Update the device driver.Change the drive letter.Use Speccy to check the status of the disk.
An I / O error is a generalized error message that occurs repeatedly in various situations. This indicates a problem with the file system, in particular, the operating system cannotaccess a specific portion of a specific disk (or virtual disk).
