Sorry if I shouldn't post here - I have Mandriva 2008 - feel free to delete my post. I want to add my 2 cents (did not see that mentioned when browsing through this discussion). I manage to destroy (as in works now randomly, with a lot of noise and only for around 5 minutes) two external 500GB HDD's in only one night. What I did - I tried to backup my internal HDD by copying it to the external HDD's. Since I selected separately which directories go on which HDD, I had 6 parallel copy commands from the internal HDD (3 parallel copy streams to each external HDD). I know it's stupid (and more slow), but I thought it would complete during the night.
In the morning both external disks were clicking like mad and the copies were stalled a little after the middle. The internal HDD is still ok. The extenal HDD's were a Samsung and a Hitachi HDT725050VLAT80, put in the same type of enclosure - (ACR-HD1098). I thought first that the problem was due to trying to copy too much (and too many streams) at once. Now (after extensive googling for 2 weeks and one lucky search term today) it appears to me that it's the same bug mentioned here, but I don't understand why it would affect an external drive more than an internal one. On the internal drive I have 193 Load_Cycle_Count 0x0032 195 195 000 Old_age Always - 16832 3 Spin_Up_Time 0x0003 253 184 021 Pre-fail Always - 4141 4 Start_Stop_Count 0x0032 100 100 000 Old_age Always - 295 Cannot get the counters from the external drives, but they do click like hell when they are working (once every 5 - seconds when I start them and they don't work, 5 or 6 time/minute at the lucky restart on which they work for more than 5 minutes): Device: Hitachi HDT725050VLAT80 Version: scsiModePageOffset: response length too short, resp_len=4 offset=4 bd_len=0 >> Terminate command early due to bad response to IEC mode page A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options With -T verypermissive I get: Error Counter logging not supported Device does not support Self Test logging Similar with the Samsung. If I have the same bug, I did not see anyone mentioning that internal/external drives can be differently affected on the same system. Hope that answers also Mark Baas question if it affects external drives - only external drives are affected on my system. Any comment would be appreciated. -- High frequency of load/unload cycles on some hard disks may shorten lifetime https://bugs.launchpad.net/bugs/59695 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
