Ciao! This is unrelated to arch, but I wanted to tell this to the list because maybe someone has a clue. I have recently bought and installed a new sata hard disk. It has a couple of partitions, one with XFS which I use as storage. It generally works fine, but sometimes something happens and it cease to work. I don't know if it's the disc's fault, because at the next restart the problems are gone. It seems that the controller sometimes gets lost. Dmesg says this: ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 ata4.00: BMDMA stat 0x25 ata4.00: cmd 35/00:20:e7:a0:f1/00:01:04:00:00/e0 tag 0 dma 147456 out res 51/84:11:e7:a0:f1/84:00:00:00:00/e0 Emask 0x10 (ATA bus error) ata4.00: status: { DRDY ERR } ata4.00: error: { ICRC ABRT } ata4: soft resetting link ata4.00: configured for UDMA/133 ata4: EH complete ...

Buffer I/O error on device sdc2, logical block 603726 lost page write due to I/O error on sdc2 So, what should I look for? Together with the disk, I installed an Nvidia 9800 GT, which could also be the culprit, because maybe I haven't a proper power unit etc. - or not? Thanks in advance to everybody!
