    [SOLVED] Disk Read/write Errors And Incorrect SMART

    Last edited for SLRist on Monday, December 29th of this year at 07:29 PM, edited 2 times in total.

    Can anyone give me some advice on how best to turn it off?

    There is one Raid-f array of 8 4TB Hitachi drives (HDS724040ALE640, also known as 0S03356). I believe they are on the hardware compatibility list to match this NAS.

    I was just “pausing” the while array while recording large video files and received an email from the affected device with the following error:

    [Hard Drive 7] I/O Error, sense_key=0x0, asc=0x0, ascq=0x0, CDB=88 00 50 00 00 01 89 31 18 08 00 00 00 80 double zero 00 00

    Re: Disk Read/write Error But Abnormal SMART

    1. Hot-swap using an unformatted removable drive that is the same size or larger than the previous one.
    2. Pour yourself a beer. (it was really hard work).

    Performance pointing to the NAS will be slightly slower when restoring this particular array, but you can use it when restoring. Downtime = 0 only a. Have fun….

    If you didn’t use RAID, the instructions would get very long and very long, and the program would take you several days if you wanted to rebuild everything by hand. Isn’t RAID sweet…..

    Re: Disk Read/write Error And Wrong SMART

    I don’t have a suitable replacement disk in the required capacity, but I ordered two and will ship them within 3 days.

    I just can’t copy the PST file from my primary email to the NAS right now: it hangs halfway through the copy process. Does this mean that the file is corrupted or that the drive is just not responding?

    Do you suggest tightening the disc to allow the muscles to bounce back until my new disc arrives?

    I don’t have one spare drive of the right capacity, but two, I ordered two. 3 days later.

    I can’t emulate my primary email PST file by booting the NAS now – that’s half the copy process. Is the suggested main file corrupt or is the drive not responding normally?

    I have no idea. I’m unhappy with Outlook, Exchange Server and possibly Windows here. Your RAID number may be “write protected” due to issues with your array.

    SLRist, you reallyisali:Are you suggesting that I remove disk 7 to get the materials back to normal until my original disk arrives?

    You can do whatever you want with it. It makes absolutely no sense to just ask for a “guaranteed” replacement. Contact WD to claim your current drive under warranty. (Hitachi Global Storage Technologies (HGST) is now a subsidiary of Western Digital Corporation Don’t (wdc))

    I have a spare drive that I definitely need the capacity of, but I ordered four that will arrive in 3 months.

    I can’t copy my primary email .pst file from the NAS, but it fails halfway through. Does this mean that the file is infected with a virus, or that the disk is clearly not infected?

  • Thanks again, Patrick. I think my concern is the main reason why the RAID array is still showing as “OK” because there is an insmart errors (sector reallocation count approaching 2000) and a red light for the drive when it recovered the device ‘and even a crash the drive is clearly readable (and not working) today.

    Shouldn’t a particular disk be automatically suspended on each array raid and continue to function normally in degraded mode?

    I’m sad that the wrong key as an active member of an array can usually result in file or parity corruption in the entire array. Are there any measures that are threatened by QNAP Raid 6?

I think what bothers me is why, given that the drive has smart errors (Reallocated Sector Count is 2000) and a red light is on when the drive is plugged into a device on the front, why is the RAID option still the same?Why is it showing as “OK” and the particular failed drive A is clearly still literally readable (and not working) to continue working normally in degraded mode?

    I’m afraid that having a bad disk as an active member of the abundance has caused the file, also known as parity corruption, throughout the selection. Are there measures in place to protect this capability when implementing QNAP Raid 8?

    You didn’t provide us with your personal S.M.A.R.T data, so it’s simply not possible to comment on anything.

    Please login to your current NAS via SSH, go to it as “admin” and run:

I think in general my concern is why the drive is showing smart errors (number of sector moves is almost 2000) and the red light for the drive on the front of the device despite the drive is showing smart errors, why is the RAID array still showing ” OK” and the failed drive is still open for reading (and failing).

    Development Shouldn’t the real disk be automatically suspended when leaving the array and continuing the raid, if you need to work normally in modified mode?
