Seagate USB HD showing I/O errors after writing operations

I have a 750Gib USB Seagate hard disk and when I copy a file to it, sometimes I get errors like this:

Code:

[ 4968.526607] scsi 6:0:0:0: [sdb] Unhandled error code
[ 4968.526612] scsi 6:0:0:0: [sdb]  Result: hostbyte=0x00 driverbyte=0x00

[ 4968.526745] Buffer I/O error on device sdb, logical block 183143645

This happens after a certain time when I list files and dirs on the disk or copy some files. It looks like to me that this HD enters on "standby mode" when no writing is being made to it, because the LED keeps flashing like my laptop's disk LED on hibernation.

I've already run fsck and badblocks on the disk, but no problems were found. Should I be concerned about this?

before you formatted the drive did you verify if that external drive has any kind of "power saver" technology? i know there are several WD externals that have that tech built into their BIOS that can ONLY be disabled via their MS Windows tools that come pre-installed on the drives.

If that is the case you might have to reformat back to NTFS, install the tool(s) from Seagate, run them and turn off sleep. then sadly format it back to ext# and you should be good to go from there unless the drive is starting to fail, then you are just sol.

I don't know if it has a power saver tecnology, but it came with some programs for backup and other stuff only for Windows. But I will search about this, thanks!
