 Posted: Wed Oct 30, 2024 11:19 pm Post subject: Corrupt File? |
 |
|
I have an xlsx file on my server that I use to help with budgeting. I've served it on my server for literal years and accessed it remotely. Today when I went to open it the file can't be found. When I looked for the file this comes up:
| ls {directory}: | ls: cannot access 'Finances.xlsx': Input/output error
[...]
-????????? ? ? ? ? ? Finances.xlsx
[...] |
A few other files in that directory show the same. This is definitely new - from within the last week. I haven't see this before and when I try to copy the file somewhere else I get this error:
| cp Finances.xlsx ~/home/{username}: | | cp: cannot stat 'Finances.xlsx': Input/output error |
Any way to recover this? I do have a backup somewhere, but I'm ashamed to say it's older than it should be. |

Looks like the drive is dying. To be fair, it is a few years old and gets regular use. I'll backup and take it from there. In good news, after the reboot that Finances file is back! So I guess I got that goin for me... |

You probably know about ddrescue.

| I do! I do not think I have a drive big enough for a backup of this particular drive though, unfortunately. I'll double check as I haven't actually used the program before and if it compresses well enough then it might work. I do have a new drive coming in the day after tomorrow and it's still working now, so hoping it continues. Thanks for the reminder. I'll check into ddrescue. |

Just backup your user data. You can always perform a new installation. Now faster than ever with the aid of the binhost. Also remember to skip /var/cache/distfiles and /var/tmp.

The drive is a not dead yet. Indeed, the pending sector count is zero, so the drive has not got any unreadable sectors that it knows about.
The reallocated sector count is also zero, so there have been no sectors relocated because they are getting difficult to read.
The Spin Retry Count is related to spinups somehow.
If the drive fails to spin up, is will never become ready and will not appear in /dev.
All your data is lost then.
While it's working, back up your user data ... while you still can.
Don't run any tests, that's wasting drive life that you may not have.
Once you have all the data you need, run the long test, it's the only useful test.
That does a full surface scan of the drive but stops at the first read error.
Tools like ddrescue are not required yet. It's main use is getting as much data as possible from a drive with failed and failing sectors. That's not you yet.
Your file may be corrupt. I've seen NFS do this a few times. The file shows like your example on remote mounts but is OK over ssh.
Check the warranty status. A SMART failure like you have is a no questions asked warranty replacement, if the drive is still in warranty.

One thing I can add is that there might be a bad connection somewhere. Have you tried another drive at the same slot?
Also I have had corrupted data due to failed sleep/resume.
Even if it turns out to be a bad connection, spinning disks are already rare these days, it must be old. You must by all means keep backups of your important data if you intend to continue using it.

The (apparent) corruption can be a bad data connection.
The SMART failure is internal to the drive.
The warning to get what you can, while you can, still applies.

It's a storage drive, so no system files on it, which makes it less complicated to figure out.

Thanks, this is helpful and makes sense. I have a new drive coming in today and once I copy everything over I'll run a long test to see what's up. It is weird that some of those files couldn't be read originally and the drive is quite old (not even sure where I got it from and I'd guess outside of warranty, though I will check). I'm not surprised that it might be failing. What surprises me is that it may not have happened sooner :-p

Maybe, but I doubt it. It's been a year or two since I last opened up the chassis, much less moved the case around, so I'm not sure how it would suddenly get loose. That being said, I imagine anything's possible too. |

cheap horrible SATA data cables fail randomly, however, they also make a lot of noise in dmesg.
The drive usually reports CRC Errors too and there are none in your SMART log.
I don't think it's a data cable.
