I wouldn't trust that drive in my computer.
#1 Dish probably uses the cheapest drives they can get ahold of. More then likely you got are refurbished drive.
#2 As that DVR that the drive was taken from was under non stop use. Any DVR will just beat the crap out of the drive.
The point I'm making is that I wouldn't trust the drive, as its more likely to fail
While I might agree the use of the drive to be less trustworthy .. I wouldn't agree with number 1.
You're making a unit.. that has to perform, as reliably as possible. Needs to withstand shocks & jolts from shipping (like UPS and FedEx would ever handle electronics with kid gloves) and that's nearly nothing compared with the thrashing of recording 2, 3 or 5 streams at once plus playback at the same time.. etc..
So I don't believe they are the cheapest .. inexpensive because of the bulk purchasing power Echostar has? maybe..
To our O.P.
As an experiment for playing with the drive and data.. sure.. go for it .. but as a thing of value? like any data that you'd put onto it and you wanted to keep safe.. make sure you have a backup (on DVD's or some such) as a safety.
... doesn't do anything ...
- Can you hear it power up?
- do you feel the vibrations as you apply power?
- in the bios - you see the drive .. do the specs there match the label? (cylinders sectors heads, LBA)
- what os?
- fdisk?
- format?
- already into an external enclosure? have you tried directly connected (sata or ide, with hardwire, not via emulation through USB "anythings")
To the "U" of it all...
- Built a pc before?
- comfortable in your own computer case?
- installed an OS from scratch?
- any dabbling with Linux/*Nix?
Please keep in mind.. most of us don't have a clue about you, so we dont' know if those are childish assumptions (like ..."no duh I tried fdisk already from windows 7 but it doesn't see..." etc) or if you have never opened the case before and got the bug to play with this thing.. so .. seriously.. more detail than the usual "it don't work" would help us help you. <:mmph:/end very slight snarkishness flung OP's way>
