USB3 backup drive rarely recognized
I have backed up my NAS to a USB3 drive using the rear USB port and it always mounted ok and did an incremental backup. Since 6.5.0 the NAS rarely recognises and mounts the USB3 drive and when it do...
Logs sent as requested
The logs show that the USB disk is virtually 100% full. Filling any filesystem that full is a very bad thing to do. You're much more likely to run into issues with a full filesystem than with one that is say 80-90% full. It does vary from filesystem to filesystem. I see that you are using NTFS.
I see in the logs "failed to read block 0xe8df809".
You should hook the disk up to a PC and check it's health using the tool from WD. If it passes you should do a filesystem check on it. You should also free up some space.
Please follow the instructions in future when sending in the logs. I didn't see any link to the thread in your email, nor did I see any reference in the subject of the email (or in the body) to point out that it was for me.
Many thanks for looking at the logs and apologies for the slip up on my part in not following the instructions ;-)
Whilst I agree not great to have an almost full drive, I have the same issue with drives even when empty. I had already chkdsk that drive an no errors were found.
I have noticed that since 6.5.1 my drive takes a long time (5-10 mins) to shut down and I just connected an empty USB HDD and it took ~3-5 mins for it to be recognised and it still doesn't show up in the shares page. I have tried to run backup with the empty drive but it still fails.
I will send you the logs from this attempt also.
Best regards and thanks for the assistance.
What about testing it using the disk manufacturer's tool? How did that go?
A quick test using the WD tool showed no problems and just finished a full test which took 12 hours and no problems again.
This seems to be a problem with the NAS more than the drive as I get the same issued with any external HDD and and cable. Any ideas?
