Hallo. Yesterday during backup I have found bad block. I have tried to fix by the remapping attempt: cat /dev/zero >pad # This filled the partition with bad block in free area. cat pad >/dev/null # This gave I/O error again - remaping failed. I booted to Seagate Tools CD and tried to fix it (it probably does exactly the same). These tools reported two bad blocks, one was repaired, second was not. Now smartctl reports also electrical error, but no problems with Reallocated_Sector_Ct: 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 4 SMART overall-health self-assessment test result: PASSED Does anybody have any explanation for the fact, that the disc is unable to re-allocate the bad block, even if probably there are spare blocks? Does it mean, that the disk is really failing?

This is a new one for me. I don't know what's happening with your disk. I suggest you treat it with great mistrust.

I have removed this disc, transported, mounted to another computer as a spare disc, completely zeroed and repeated the whole procedure. Surprisingly, now Seagate Tools report the disc as OK. > 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 4 Reallocated_Sector_Ct increased from 4 to 6. The conclusion: It seems, that in some situations S.M.A.R.T. is unable to detect bad blocks, but later, when these blocks become even worse, it remaps them without any problem. But I still treat this disc with great mistrust. ________________________________________________________________________ Stanislav Brabec http://www.penguin.cz/~utx, ICQ 116020046 |
