If my memory serves me correctly, some time after the 7933 was announced and became quite popular, HP had a massive "recall" in order to change faulty heads that were causing disk crashes.
This required CE's to replace the heads on any affected 7933 at the next opportunuity - usually the next preventative maintenance call.
Now here is where my memory may be a bit fuzzier, but I seem to recall that around that time, HP announced the 7935, which was exactly the same as the 7933, but was modified to permit the user to replace the disk pack itself.
(Perhaps the 7935 was the original and the 7933 was the one with user-replaceble disk packs.)
