I/O error on external HDDs

Hi everyone,

I get I/O errors using the external 4 bay enclosure Icy Box IB-3740-C31 since I installed Archlinux half a year ago:

The errors appear with all HDDs of all ages and sizes. I sent the Icy Box IB-3740-C31 back and got a new one, which shows the same errors. Recently I got a new HDD and needed to fill it with random Data in order to luks encrypt it, so i did a few tests:

With

dd if=/dev/urandom of=/dev/sdd bs=4096 status=progress

I filled it with data and the I/O errors appeared again. The write speed was about 61.5 MB/s. Then I used the same command on a different computer on debian (so not arch) with the Icy Box IB-3740-C31 for about four hours and no I/O errors appeared. The writing speed was about 188MB/s, though this could be due to a faster single core or a bigger entropy pool.

So I bought an Icy Box IB-AC704-6G USB to SATA adapter and tried the dd command on my arch machine and the speed was again 61.5 MB/s but no errors appeared. I used the same USB port for the Icy Box IB-3740-C31 and the Icy Box adapter.

In conclusion: Icy Box IB-3740-C31 on debian is fine, but not on arch. The same USB port and the same HDD with the Icy Box USB adapter on arch is fine.

Has anyone an idea what is going wrong here? Could there be a firmware missing?

Thank you and best regards,
Offerus
