After re-adding my HDD to the RAID and waiting for the synch to complete, I retried
$ sudo LANG=C apt-get update
[..]

Strace'ing suggests that the file /var/lib/apt/lists/de.archive.ubuntu.com_ubuntu_dists_intrepid_main_binary-i386_Packages is to blame.
And indeed:

$ LANG=C dd if=/var/lib/apt/lists/de.archive.ubuntu.com_ubuntu_dists_intrepid_main_binary-i386_Packages of=/dev/null
dd: reading `/var/lib/apt/lists/de.archive.ubuntu.com_ubuntu_dists_intrepid_main_binary-i386_Packages': Input/output error

cat: /var/lib/apt/lists/de.archive.ubuntu.com_ubuntu_dists_intrepid_main_binary-i386_Packages: Input/output error

Same is true after I remove the SD card from the RAID.

HELP, this thing eats my data!
