cp -> read only fs
hdb is a new disk, seagate es.2 , bought it yesterday
after a while:
end_request: I/O error, dev hdb, sector 362948927
end_request: I/O error, dev hdb, sector 362949423
& long series of
cp: writing `./a/b/c': Read-only file system
i unmount disk, try to mount it back
mount: you must specify the filesystem type
fsck.ext2: Attempt to read block from filesystem resulted in short read while trying to open /dev/hdb1
Could this be a zero-length partition?
hdb magically starts working after i reboot pc and boot linux from it, then i boot back to hda. so far i did that 5 times
smartctl -l selftest /dev/hdb
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error
# 1 Extended offline Completed without error 00% 8 -
any ideas what could be wrong, should i try to return this disk ?
Timing cached reads: 16184 MB in 2.00 seconds = 8099.27 MB/sec
Timing buffered disk reads: 218 MB in 3.01 seconds = 72.41 MB/sec
Timing cached reads: 15948 MB in 2.00 seconds = 7981.33 MB/sec
Timing buffered disk reads: 12 MB in 3.20 seconds = 3.76 MB/sec
i'm also curious why does one disk have name sd*, while other hd*,
they are both SATA drives, hdb "buffered disk reads" just 3.7 MB/s ?

what filesystem is your Seagate drive using. New hard disks usually come with a FAT filesyste so if your trying to copy from a linux ext3 filesystem to a FAT filesystem, those are the sort of errors that might crop up. Try formatting your new drive to the same fs as the old one
