I think you have two valid options. There appears to be some experience of using Skyhawks in Humax PVRs but none documented here that I can recollect. People have successfully used drives that didn't seem ideal such as Western Digital Red (intended for server and NAS usage) and taken the time to report back here that they are still working fine some years on. I think it is a close call. My very personal opinion would be to try the Skyhawk because I have just had too many bad experiences of drives that are not necessarily brand new; however maybe I have just been unlucky and the majority of them are fine.If Pipeline really is best then I'll have to risk a third party seller. I suspect this is what @MattAnorak bought in this thread: https://hummy.tv/forum/threads/replacing-hard-disk.9691/ (post 16) and his seems to have been OK (so far!).
If Skyhawks are OK then I'm more tempted to buy direct from Amazon.
You got me worried for a minute until I checked the drive in my HDR. SMART data reports it as ST3500312CS, Firmware SC13, SATA version 2.6, 3.0 Gb/s (current: 3.0 Gb/s)That pic shows you've got a sata1 drive. Look at post 37 of this thread. You need a sata2 drive or above for the HDR to use it. The P/N code on the drive label looks a little low.
Looks like it's not as simple as that.It's the "9GW132" that's the determining factor.
With the firmware the same it suggests the p/n suffix is a customer reference.Agreed, but what I meant was the "SC13" bit you quoted hasn't been referenced previously. IIRC the lowest number that has been reported to work is 9GW132-075.
Yes, I know and this should have been clear from my use of it. I used the abbreviation P/N as it's used on the drive label....generally stands for Part Number, a manufacturers internal identification separate from the published catalogue code. It seems likely that "9GW132" is a product specification and "-012" is a revision number.
Recap. So - the drives used by Humax HDR and old Sky boxes are very similar even down to the model number and the firmware. The only difference being the part number 9GW132-191 (for the HDR), 9GW132-xxx etc found in other places. I wonder if the other drives have DCO set?What appears to be needed is some means of sending the correct SMART Command Transport (SCT) code to the drive that sets it back to 3Gb/s, assume that it's not a one-way process. FWIW I wondered if the undocumented jumper position that on other drives limits the transfer speed to 1.5Gb/s in this case has its operation reversed but no.
