Compact flash cards issues may cause high CPU activity

I'm not surprised fsck_msdos gets run on the card; filesystems are always verified before being allowed to mount read-write. Some filesystems have "sync" marks on them, so the mounter knows right away if they were taken offline cleanly. Otherwise, or if the mounter can't tell, the filesystem gets fsck(8)ed first.

Apple's had some bugs in fsck over the years; there was an integer truncation error in the 10.0-10.2 fsck_hfs and I sent them a little patch and a little bug report, and they fixed it in Tiger.
