Yep it works Great !
Yes this definitely works, and has for me since February.
Currently using two drives 1TB an 2TB
The photos in Album in my User Profile, I thought were pretty clear as to setup, takes more time to take photos and upload than do actual SATA setup
-Disconnect and put 530 receiver on a table,
-use small side cutter pliers to remove safety screws and remove cover
-unplug the green circuit board from back of old hard drive
-unplug power plug connecting this green circuit board to power supply inside receiver (its not needed anymore)
-cut a hole in receiver cover (or you could route wires out back of receiver)
cutting a hole lets you have new drive at front of receiver to access easy
-if you cut a hole make sure to cover sharp edges of hole to stop wire rubbing
-connect new power wire with large 4 prong power plug to power supply and run its opposite end the small plug, out hole in receiver cover to the Startech IDE>SATA adapter
-put green circuit board up through hole in receiver cover
-connect IDE end of IDE>SATA adapter to green circuit board (watch that you put missing pin in same spot check your old drive where it is)
-connect SATA end of IDE>SATA adapter to Dock or directly to SATA hard drive
-move receiver back to TV connect it up, connect power last
-let it power up, do FACTORY RESET to format new drive, get a rehit/refresh and your in business (do this for each of your new drives and then they are switchable)
To switch from one drive to another, turn receiver off, disconnect power plug from wall, remove SATA drive1, put in SATA drive2, reconnect power, turn reciever on.
Other than removing those security screws and cutting hole in receiver cover this could be done in 15 minutes, once you have the 2 to 3 parts needed.
If you want big capacity this is a way to do it
You can just switch the IDE drive currently in receiver for another bigger drive but it has to be a Seagate drive an IDE and they are I believe no longer manufactured.
