Yes, but it is very unlikely. I have written TB of data there without any problems. Anyway this is my 3rd exchanged SAMSUNG disk ...

I tried to disable NCQ on all disks and tried to rebuild the raid, but it still failed to rebuild with the same error message.
I also tried the nolapic kernel parameter without success.
/dev/sda: 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0 /dev/sdb: 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0 /dev/sdc: 5 Reallocated_Sector_Ct 0x0033 091 091 010 Pre-fail Always - 413 /dev/sdd: 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0 /dev/sde: 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0 /dev/sdf: 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0
The only thing is that the Reallocated_Sector_Ct is still >0 on /dev/sdc (keep in mind this is my 3rd new Samsung disk on /dev/sdc and I had up to 3000 Reallocated_Sector_Ct on previous disks in < 1 day !!!).
Should I replace the disk a fourth time?
When you search in google you find a lot of threads with the timeout problem. Might this be a software issue?
Any ideas?
Thnx.
Ciao, Gerhard
