'Repurposing' Foxtel HDD ??

[gordon_s1942]

While browsing at my local 'Shopping Centre' I found amongst the flotsam a Foxtel IQ STB.
You see lots of large black boxes of indeterminate age and in various stages of assembly but not bearing the Foxtel logo.
After applying my faithful 'Armstrong' case opener I found the HDD was still in place and it says its a WD 3200AVVS, eSATA type.
Even though this HDD is only 320 GB, tiny by todays standards, can I reuse this as a HDD or is it 'locked' forever to being in a Foxtel stb?
I am not interested in what may or may not be on the drive, only if I can use it connected to something.
My query is contingent of course in that the HDD is still in working order and not stuffed.

It will take me all of 2 minutes to arrange to return the HDD and the case back to where it came from sans any scrappable content.

No reason why it can't be reformatted, etc.
