External HDD mounting issues

[utamav]

I recently lost an external HDD during a router upgrade. So I bought another drive to replace it. My previous drive was Seagate 3TB with external power. I also have a 4TB WD (older model) with external power. Since WD was working flawlessly my replacement drive is 4TB WD (newer model) with external power.

Now the newer 4TB WD won't mount in either port.

These are the syslogs:

Does this mean that the device is too big?

That message does not indicate a problem. You can see that the disk is attached:
Jul 23 21:58:21 kernel: sd 4:0:0:0: [sdb] Attached SCSI disk

Try reformatting the drive as it looks to be having trouble mounting it. There seems to be a problem with some drives, if possible use ext4 instead of NTFS.

Thanks, I'll try that.

All my drives were working fine until now. The one connected to the USB 2.0 port is not being detected by the router. I've tried rebooting the router and also re-plugging the drive. Following is the log:

Then I keep getting this message:

FYI, after previous issues, I formatted both my HDD as EXT4. Both my HDD are 4TB WD with external power source.

Some more logs:

I'm going to remove the drive from the port for now.

any help?

Your disk isn't responding properly to command. There could be a number of causes:

1) Bad sector causing the HDD to stall/ freeze for an extended period of time
2) Bad USB cable
3) If it's a bus-powered HDD that draws its power from the USB port, these can be very touchy, and seem to become worse over time. Best to use an HDD that has its own power supply.

I'd started first by doing a surface scan of the disk from a PC, and replacing the USB cable.

 

[utamav]

Thanks. The HDD reads fine on the PC and no bad sectors. I'll try again on the router.
