OK, 0x0748 for Western Digital probably means one of the My Passport range. Thanks.

Hi Graham,
Yes, that's right the My Passport series (2 TB). Do you think it's something with these drives?

greetings from Hamburg

Sorry, I don't know.

I guess that within release notes for a future update to ZEVO, there will be something that explains cases such as yours.

Towards closure of this topic

alexxx_dragon, please, are you perfectly happy with the most recently created ZFS pool and file system on this My Passport series (2 TB) drive?

Cross reference

Need recommendation

Western Digital USB drives hide drive failures and SMART status when hooked up via USB. I have had drives that seemed to work just fine, but when pulled from their cases and attached directly to a computer using SATA, they fail manufacturers SMART testing and such. The drives I were using had 2TB WD Green drives and I even had problems with them after running badblocks on them for weeks.

I would recommend ensuring that your drives get scanned!

Hi Graham,
until now I never had any problems with this drive again. So I would say: Yes I'm perfectly happy. But this is not the drive I asked the recommendation for.
@redwards: Thanks for your suggestion. But, there is no way to hook this drive up to SATA because it's 2.5 and it has no SATA connection. I opened the enclosure because I tried to do exactly what you recommended. So no way to test this. I did a ZFS checkup and that was fine.

Greetings to all from AleX

Thanks redwards (and alexxx_dragon) – some of this fits neatly under:

my devices with known imperfections or suspected issues

PS (OT): dear operating system, please stop autocorrecting quoted names. redwards is probably R Edwards (not Red Wards).

I find that surprising, 2.5in drives typically either have SATA or PATA(old) connectors. Do they make drives with USB controllers now? If so, I haven't seen them yet. Links?

@graham: or, even better rewards...

According to Amazon that is WDBY8L0020BBKNESN

A search of the "complete" Western Digital site finds nothing http://www.wdc.com/wdsearch/?sq=WDBY8L0020BBKNESN but that may be a false result.

Elsewhere I find http://support.wdc.com/product/kb.asp?m ... 020BBKNESN
