Since you have taken the disk apart it will now be useless as within the enclosure there could have been a vacuum or an inert gas.
From what I know gas filled disks didn't exist in the times when 3X0GB was on a 2" drive.
You will never be able to recover any data on the disk unless you go and pay for a professional data recovery organisation to read the platters.
No, if he did care that the disks didn't become dirty then the drive should still work quite well to recover what is on it. Of course the cover should be put on ASAP. If you don't believe me, just try it our yourself.
The price for a replacement 340GByte USB disk is about $25 which would give you a better product than your old disk.
The OP wanted to recover what is on the disk, not use it as a normal disk.

I have an old external harddisk, Toshiba 320 Gb, with a USB connector that I wanted to check for contents. It did not start up when connected and I could not hear the motor spinning. After leaving it in the freezer overnight the motor spins but it is not recognized by my computer. I disassembled it and could see that the head assembly rests outside the disk but when it is powered on, the head first moves to the center of the disk, then to the periphery and finally back to the resting position. This happens every few seconds and leaving it connected overnight changed nothing.
That repeated seeking suggests it's not passing its self test, and is constantly retrying. It's probably searching for servo data on the disks, and not finding it.

I see. I have not searched for any low-level disk utility from Toshiba, the manufacturer of the disk. Do you think that might be worthwhile to hopefully fix this?

Simon, you are correct in all the above and I replaced the cover as soon as I had ascertained the movements of the head assembly.
