What kind of problems chkdsk can identify? Are there any disk problems that chkdsk cannot identify and will mark a malfunctioning storage device as a healthy one? Are there cases when I would need to use other tools to check disks for logical or physical errors?

If you run it it will tell you what it does, it checks the file system.
If you add the F or R switch it will require a reboot, then along with the file system it will read every sector on the disk to verify the integity of the read surface and attempt to fix that sector (recover data) or replace the sector with a spare and mark the bad one so it does not get used again.
This is a check of the physical health of the drive surfaces only but is not a full disk diagnostic.
Reading the SMART data on the drive is a better indication of overall drive health, and chkdsk does not do this.
