I've got quite strange question: what is the value of the condenser which is
placed in WDAC21000-00H hard drive on the reverse of the integrated circuit.

When You unscrew and reverse the green part it should look like below

Hard drive parametrs: WD Caviar21000 MDL:WDAC21000-00H Cap:1083.8MB Cyl:2100
Heads:16
The place of requested condenser is marked as 'x'.

Peter, I think the following picture may help but I can't be certain
because the PCB and rest of drive weren't together, it was removed and I
don't have the rest of the drive.

Anyway, the location of the condenser (capacitor) is the same and is
connected to the 5V power source and ground in the circuit. The following
is a 150K picture, slightly enhanced. Note that some components may be
missing as this PCB was somewhat cannibalized, in particular the power
plug socket itself is removed. According to your ASCII art picture this
is the component you're asking about.

It is 10uF but you should be able to use a larger value instead if you had
another value available,but be sure voltage rating of replacement is over
5V.
