Given the importance of GBPVR for our state of happyness and the effort having to re-install I am considering some measures to increase to robustness of our recording server.
One option is to convert the System Parition (about 6GByte) into a software based RAID 1 using a small partition on another disk.
By having the two mirrorred disk on separate IDE channel (yes, I am cheap) the performance impact should be acceptable.
The system is on 24/7 and it supports SW raid by default.
I tried the migration with an old shadow copy of the system disk on a spare PC and it takes less then one hour to do the conversion. Rather straightforward.
The main reason for not doing this is because the disk migration software I know of (maxblast) can not handle dynamic disks so I am stuck with the partition size, or will I be able to extend the partition in a decent way?
Or I could try to find some way to monitor the SMART info from the system disk and have me send a mail when it is in bad shape so I have still time to migrate to another disk.

What would you guys recommend?

I dont know about the partition resizing, but I am sure there is something out there which will send you a message when the hard drive starts going bad.
this is probably kinda overkill, but I use samurize, and I know that there are plugins for HDD SMART statistics, and I know that you can create alerts which will run a command, such as a batch file which will send you an email.

as for being cheap, you could try using standby so the system is not "on" 24/7. :p

I would recommending spending a little cheap money on Acronis TrueImage, and image your boot partition to a USB drive/stick.. then when 1 drive dies.. you can just boot off the CD and insert USB/Stick copy image to new drive.
Code:
[b]System Specs:[/b]
AMD64 3000+ (1GB DDR 400 in DualChannel mode)
WinXP Service Pack 2 (most updates)
80Gb SeaGate SATA (boot), 160Gb (noname) SATA(video archives),
500Gb SeaGate SATA][ (Recordings)

[b]GBPVR:[/b]
   99.12 (All Survival Patches)
   (PVR150/OnAir GT USB, ZProcess, ShowBurn) - N/A at  moment
   Recording of DualTuner DishNetwork 622
   1 MVP (connected to 36" SDTV)

The system also doubles as our external web/mail server.
The CPU uses only 7 watt. All disks except the system/web/mail disk will powerdown when not recording or being used as internal file server

Once the system partition has become a dynamic disk you should expect to be able to use "extend partition" but this is only possible for partitions originally created on a dynamic disk. So that is a nogo.

Thanks for the tip on Acronis. However that seems to be for a trial version....

Not a trial version, but a license + serial number for a previous version I think. Still working here for me since October last year. I think their incentive is to get you to upgrade to a later version, but the earlier one doesn't seem to be crippled in any way.

Nice, but I can not find the download link for the previous version??????
I did receive a produkt key.
Can someone mail me the installation file for version 7?
Or the link to the download

- Edit -

I found the link, its under "upgrades"
Seems logical (????)

only bad one with on-board HW raid, when it failed the supplier had to setup & install a complete new machine, guess what: data was lost, no recovery possible cause the same board no longer available, thanks god we had a regular backup & could restore data after last backup from print-out Smile

i'm not sure if there is a tool out there capable of enlarging dynamic disks, last time i searched for one 3 years ago i found nothing. then again: 3 years is a lot of time Wink
