more info on upgrading the CIS430 would be appriciated, is there a guide? is it as simple as swapping the connectors on the 5v/12v and mirroring the drive?

You'll find that Telus records more hours/GB than TiVo since it stores the native datastream which is MPEG-4. TiVo series 2 encodes analog signals which takes more space. TiVo series 3 stores MPEG-2 OTA signals which take more space than MPEG-4. According to the Telus web site:

Record up to 115 hours of HD programming or 295 hours of standard definition programming.
In addition, I would be leery of anyone claiming that they can expand a Mediaroom PVR to 2 TB, since I've read several places that the underlying OS (Windows CE 5) only supports drives up to about 500 GB. If you want to proceed, I would suggest using a drive designed for a PVR, preferably the same manufacturer and series as the original.

Where did you read that? Windows CE 5 has only a (theoretical) limit of 128 petabyes for the hd, using 48-bit LBA. If they happened to use FAT32, they'd be limited to 32gb partitions, so I doubt they did that. Where would a 500gb limit come from?

Meestor_X, most of the info I've seen on the subject has been AT&T Mediaroom users experimenting with upgrading their hard drives. My understanding is that Mediaroom allocates a small FAT partition and the remainder of the drive as FAT32 for storing the recordings.

Mediaroom preallocates the FAT32 partition with 1 GB files and does it's own file management, presumably to avoid fragmentation and improve performance.

The 32GB limit was introduced in Windows 2000, because performance can degrade with large drives in a general computer environment. Windows 98 FDISK could create FAT32 partitions up to 512GB. Perhaps Windows CE 5 has the same limitation.

CIS 430 HDD Upgrade

I just purchased a CIS 430 HD PVR, and noticed that the 320gb WD Blue HDD is very easily assessable.
Has anyone had any experience replacing the HDD with a bigger one?
Idealy, i would like to put at a 2TB HDD in, but im assuming ill be lucky if it even supports 1TB.
I have read some people talking about it before, but no one actually doing it.
Is it possible?

If you purchased the unit, you can remove the drive, clone it to a larger drive and see what happens. If it doesn't boot up, you could put the original drive back in. Of course, it's easy for me to say this, but I don't own my PVR and I don't want to deal with the consequences if it doesn't work.

The only update I have is that Telus now says that you can record up to 198 hours of HD on the current PVRs. That should satisfy most people.

I haven't seen anything new on hard drive upgrades for any of the Canadian telcos (which all run MediaRoom). I haven't checked AT&T lately though.
