A few years ago when I was still using TiVo boxes that had IDE drives in them, I had a 500GB drive fail while still under warranty. Seagate shipped me a 500GB drive, but I got impatient and replaced it with a new one before the warranty replacement arrived. Recently I was going through some boxes of TiVo parts and I came across the drive.
It is a Seagate 7200.10 500 GB "Certified Repaired HDD" still in the anti-static bag. It appears to have been manufactured around 2010, as the date code is "10303" which means January 23 2010. Made in Thailand.
I thought there might still be some TiVo owners that need a drive like this for their Series 2 TiVo boxes.
Make me an offer. If I don't get anything here, this drive will go up on eBay next week.
