Title: Repairing Disk Errors
Post by: Cliff on March 22, 2013, 07:11:53 AM

I have two drives in my DNS. Running v1.09.
The volume types are both (2TB) identified as 'Standard' which I'm guessing means not RAID. Anyway, volume_1 was starting to timeout with file transfers and just being generally slow.

I ran the disk tool check on it, but rebooted the DNS using the gui after it was only at 27% done after 20 hours. I am copying some stuff to another drive. It is very slow, 1.8MB/second but files are copying.

Two questions.
1. Is Volume_1 the Right or the Left Drive?
2. Is there a way to run a repair utility on the drive, or do I toss it after copying what I can from it?
Thanks in advance
Cliff

Have you ruled out network issues?

• Have you tried swapping out the network cables? (a bad cable can lower throughput)
• Are you accessing the DNS-323 from a wired or wireless device?
• How is the DNS-323 connected to your network? You may want to try wiring the DNS-323 and the client PC directly to the same switch (if you have one available).
• Reboot your router and make sure other devices are not trying to access the DNS-323

Now I seem to be having issues with both drives.
The unit has been working fine for many, many months. No changes have been made.

- I did swap out the Cat 5E cable with another
-DNS is wired GB to a DLink 1008D switch. PC is connected to the same switch
- Router, switch, PC and DNS have all been rebooted
- Performance is still very poor, less than 2MB/sec on both drives

Since you are having problems with both drives and they are not part of a RAID array you could pull one and put it in either a USB/SATA caddy or adapter then plug it into a PC on which you have the drive manufacturers disk test software installed.  Then run the disk tests.

This will determine if it is the disk that has the problem or if it is something else.

Likewise, while you have the drive out of the unit, get either an IFS or some software that can read Ext2/3 file system and copy your data that way.

If you have a windows PC, DON'T try to read the disk without either the IFS loaded at boot or some software that understands the Linux file system.

As timing would have it there was a one day sale for a ReadyNas Duo V2 for $99.00. I put a 3TB drive in it, and in 14 hours, tech gods willing, all the movies/videos will be moved from the DNS to the ReadyNas.

Then I'll format the drives in the DNS and see if a clean slate can fix the performance.
