raid1 disk failure
 
While trying to booth with a computer with two SATA HDs, software raid1 (booth ext2, otherwise ext3) sda/sdb, Debian GNU/Linux amd64 wheezy, the system crashed, with message

I/O error, dev sda, sector 11510982
EXT3-fs error (devive m-2): ext3_get_inode_loc: unable to read inode block -inode =286730, block=1146917
exception Emask
failed command: READ DMA
ata5.00: status |DRDY ERR|, |UNC|

Switching power off, then on and boothing, it did. However, I checked:

while, with sdb there was no such warning.

I hope that someone expert in these affairs can comment on the reliability of sda at this point. Change the disk?

Thanks a lot

So you got a disk IO error, ran the smart tools and were directed to a page at Seagate for more information (and got errors)....and you're wondering if you're having a disk problem????

Go to Seagates page, and read/follow what they're saying. The link you posted won't work, but if it's telling you that you may have a firmware issue, then you may have a firmware issue. Read what they say about it, and take whatever steps they suggest to resolve it. Disk IO errors are usually indicative of an impeding problem. Have you checked the system logs????
