Hard to tell, by making a new file you are using a different part of the
disk. the program 'badblocks' can scan the partitions/disk for unreadable
sectors, that would tell you if it's a physical problem. You should also
read the boot logs (messages) and see if fsck said anything last time you
booted...(do NOT fsck the disk while the machine is running)

Also look in the messages for any thing about 'VFS' errors, that would
tend to indicate filesystem issues , tho hardware problems generally
cascade into other problems...

That admin thing only tells you they appear to work overall, it won't
necessaruly complain about a small error somewhere like one bad block...

May be another file somewhere, i hope you are making backups regardless,
also, running a backup may turn up other files you can't read...(or you
could just do that to see)

try something simple like du / , see if you get funky errors while it
tries to add up all the disk space....
