I have an older USB drive that works with many computers, but failed on a newer one. The newer computer usually has issues on its USB3 port, but later has issues on USB2 as well. The USB enclosure has an additional USB cable for getting power from the second USB port. Plugging in the second USB cable worked for some time, and the USB randomly spits out the above errors. The problem seems related to boot up. When this newer computer has USB issues, it will always have the issue till reboot. --00000000000019303105e9214f30 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr"><div dir=3D"ltr"><br></div><br><div class=3D"gmail_quote">= <div dir=3D"ltr" class=3D"gmail_attr">On Tue, Sep 20, 2022 at 6:33 AM Chris= toph Brinkhaus <<a href=3D"mailto:c.brinkhaus@t-online.de">c.brinkhaus@t= -online.de</a>> wrote:<br></div><blockquote class=3D"gmail_quote" style= =3D"margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding= -left:1ex"><div>Am Mon, Sep 19, 2022 at 09:40:42PM -0600 schrieb Gary Aitke= n:<br> <br> Hi Gary,<br> <br> > I have a system I need to back up and my only available backup disk is= <br> > throwing a lot of errors like:<br> > <br> >=C2=A0 =C2=A0 (da0:umass-sim0:0:0:0): WRITE(10).
