Suggestions?

Yesterday I noticed messages like the following appearing in my logs, accompanied by delayed access to some log files:

Jan 14 10:16:08 www kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error } Jan 14 10:16:08 www kernel: hda: dma_intr: error=0x40 { UncorrectableError }, LBAsect=1803697, sector=823672 Jan 14 10:16:08 www kernel: end_request: I/O error, dev 03:01 (hda), sector 823672

I hadn't been using the drive's SMART capabilities, but I enabled SMART and ran a short test:

SMART Self-test log structure revision number 1
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Short offline Completed: electrical failure 90% 6433 0x002da85d

I've used parted to mirror a drive before, but I wanted to ask for suggestions on any additional steps i should take, being that this drive is possibly damaged. What can I expect from copying my data to another drive? Is corrupt data on the target drive likely?

Here is the output from parted /dev/hda print:

And here is my SMART error log:
