--- Comment #1 from Christian Kujau <lists@...dbynature.de> ---
"the hard drive produces a distinct clunk every few seconds" sounds like
hardware problems. Other file systems have different access patterns and it may
not be vis^W audible with e.g. NTFS, but I wouldn't trust a hard disk that
makes "clunk" noises. That being said, there are crucial parts missing from
this report: syslog errors during the access problems (a full dmesg may be
helpful too); does it happen with a current vanilla kernel? Also: has this been
reported to the linux-ext4 mailing list prior opening this bug?

Also, this error seems to be rather common with Raspberry environments, see:
