I have ordered a SATA hard drive to USB dock off eBay, due to arrive any day, I will then be able to test drive without pulling my old Mac Pro apart. I have already fitted a SATA hard drive from a Bush 500gb Freesat that I had, befor I upgraded to Humax, but it looked physically very different (much smaller but not a laptop type) but I still think it should have worked. So I am a bit sceptical about it being the drive. By the way the old cheep Bush unit, that cost less than half the price is still, going strong. The Humax is a much nicer product but I am now starting to wonder why I bothered.

For your interest here is part of a Seagate article of hard disk failures for one of their PC drives.
"The product shall achieve an Annualized Failure Rate - AFR - of 0.73% (Mean Time Between Failures - MTBF - of 1.2 Million hrs) when operated in an environment that ensures the HDA case temperatures do not exceed 40°C. Operation at case temperatures outside the specifications in Section 2.9 may increase the product Annualized Failure Rate (decrease MTBF). AFR and MTBF are population statistics that are not relevant to individual units.
AFR and MTBF specifications are based on the following assumptions for business critical storage system environments:
•8,760 power-on-hours per year.
•250 average motor start/stop cycles per year.
•Operations at nominal voltages.
•Systems will provide adequate cooling to ensure the case temperatures do not exceed 40°C. Temperatures outside the specifications in Section 2.9 will increase the product AFR and decrease MTBF."It is worth noting that the freesat app, when paired, will increase the motor start/stop cycles from say 400 p.a. to some 26000 p.a.
That said I am very doubtful that these cases are drive failures.

Anyone know if there is a fail-safe to warn or prevent use in event of fan failure?

Many audio units I used to work on would shut down in event of fan fail. PC will give warning how do Humax handle such an event?

PC will give warning how do Humax handle such an event?No idea, However many CPU's incorporate this function directly within the processor. You should also note that using low power drives should lead to less heat. Low temperatures give a lot of problem is the drive is operated cold. Portable drives should be drought to room temp before operation.

I now have usb hub for SATA drive. The HDD from my HDR runs up fine. Disk Utility on my Mac can see the drive which has three master boot record partitions
partition 1; 1.8gb
partition 2; 998.38gb
partition 3; 10.74gb
But does not recognise the format so the drive will not mount. So hard drive is working and partitioned but I do not know what format to expect. I also run Windows 7 as a virtual machine, result much the same PC knows there is a drive there but can't see anything on it.
I also have Linux working as a virtual machine. The Linux machine can see and read all three partitions although has not the software to play the files. Looks as if the Drive is okay.
Now what?| Wed 9 Dec 2015 18:30:40 #48 | -

I am tempted just to reformat it FAT install it back in the HDR and see if it offers me an option to format it. But befor I do that I will connect it on usb and see if the Humax can see it but I will wait for replies first.The disk will have Linux EXT3 file system The recording partition is LUKS encrypted.

Yes that's correct thanks I have tried it on my Linux virtual machine and the Linux machine can read the file system cannot read files. So drive looks good. I will try it in HDR on usb tomorrow.
Thanks for help| Wed 9 Dec 2015 19:39:16 #50 |
