LS-CH1.0TL Started to E07 (red 7 times) only occasionally...

[Mickets]

I've had my LS-CH1.0TL for maybe four years now, and never had problems. Until now.

I recently bought a new HDD for the computer, upgraded to Win 7, etc, and decided to review the NAS settings and status. I found that the NAS was 99% full, but I hadn't noticed because the e-mail alerts has long stopped being sent, due to changes in the SMTP settings for my ISP.

The bulk of the data filling the NAS was the Trashbox in one folder, which I started to clean by accessing the Trashbox via DOS and running a FOR %A IN (*.*) DO RMDIR etc... That took long but NAS usage is down to 70% now.

Another thing is that I never got the NAS to work in Auto mode, because whenever Cobian Backup started to backup to the NAS, it was asleep and Cobian couldn't find it. I'll eventually set a WOL for that, but this was long ago and I decided to just leave it On all the time, almost 24/7.

But the other day I decided to enable the Spin Down options, etc, to try and preserve the NAS a bit more.

Having said all of that, after these changes I eventually got home one day, turned on the NAS, and it started to flash both LEDs in color Red , 07 short times. THe handbook states that's an E07, which means "no HDD found". But... the HDD is there!

I un-plugged and re-plugged the NAS various times, and then suddenly it was alive again! Problem solved! I thought.

Yesterday I returned home and found the same problem when trying to start it up. I un-re-plugged various times, and after maybe 20min fiddling around, it was alive again!

Since then, I started copying important backups from the NAS to my second HDD on my PC, and left the NAS in "On" mode again.


Question: what could be causing the NAS to be intermittently issuing error E07 (no HDD found)? Could it be a lose cable? I wouldn't think so, because I didn't shake or open the NAS (been for years in the same place, never been pulled apart).

I imagine that if it were something major, such as the HDD failing, it would fail once and for ever. That is, I wouldn't expect it to die then resurrect successive times.

Anyway, what do you think about it? Need to worry? Time to change the NAS' HDD (or simply get a new NAS)? Can the HDD be changed?

Thanks for any help.

Bump.

Well, the other day the power went out for so long, that the battery of the UPS ran down, and the NAS got powered off. And then it wouldn't work again. Same symptoms.

I tried re-starting it a number of times, and... now it's working again.

So, it seems that the drive is OK, just that for some reason it is sometimes not found or something like that.

Ideas?

Id say the HDD is failing, setup email notification and see if it reports any bad sectors.
