Yes they work. It's a heavily spammed urban myth that Replay 5K drive compatibility is a function of HDD cache size
It's such an appealing fantasy even you fell for it?
You opened that message, took the *claims* for fact, and probably forwarded it to 999 others?
However with the Seagate Barracuda, the reality is it's the firmware series that (apparently) predicts compatibility in a 5K. 7200.7, 7200.8 are (apparently) always compatible even with 16 meg. 7200.9 and 7200.10 (apparently) never are even with 8 meg. We have constant reports of people getting started with 7200.9 ugrades and claiming it works only to find out they were loosing all recorded shows every week (maintenance reboot) or everyday (won't record at all, freezes/reboots) in fact here
is another one today. I'm guessing either it won't prove reliable, or hopefully it's actually a 7200.7 or 7200.8 drive.
Seagate DB35 series (so far) are (apparently) all compatible: 7200.2, 7200.3, so if you can find one of those (good luck) they should be a safe bet.
Not sure what is going on with Maxtor drives but Maxtor is now owned by Seagate. For the most part reports indicate Western Digital drives nearly all work, but many don't like the noise -- myself included.
And of course to make it more confusing the Seagate retail kits quite often don't match the firmware series listed on the box. Additionally too many vendors don't honor a distinction between 7200.7, 7200.8, or 7200.9 in what they list and what you get. You might see a place listing a Model: ST3300631A as a 7200.9 when it should be 7800.8. But what's in the box is actually a ST33300622A. Confusing enough yet?
Fortunately (so far) it seems that what's printed on the label of the drive itself is what you've got. So for Barracudas, OEM drives may be more likely to be listed correctly.
