I have a Dell OptiPlex GX270 with a PCI SATA card in it. There are three hard drives, a 60GB DeskStar IDE, a 250GB Western Digital IDE, and a 1.5TB Western Digital SATA.

I'm running Lucid with all updates as of posting.

I have my drives partitioned off below:

Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 2403420 345680 1935648 16% /
/dev/sdc1 240362656 227962440 190416 100% /home

/dev/sda6 2403420 502028 1779300 23% /var/dev/sdb is the SATA drive in question. Every time I copy a file from it (cp /home/media/movie.mpg .), I get the following message filling up my syslog:

It continues until it gets re-configured for "UDMA/33", and continues to fill the log.

I do not appear to be losing data because of this, but it does take what I would imagine is "way too long" to copy files involving this drive.

The hard drive is brand new, as is the SATA card (I've tried a few SATA cards even). I found various posts suggesting maybe not enough power in the box, so I bought a bigger power supply with no avail.

Does anyone have an idea how I may resolve this? I'd be greatly appreciative. I have attached syslog & dmesg to hopefully help out and can provide additional information as requested. The attached syslog involves a boot and immediately copying a 79,234,456 byte file from /home/movies (aka /dev/sdb1) to /home/user (aka within /dev/sdc1).


$ sudo hdparm -tT /dev/sdb1
