Has anyone tried using one of the new 4K sector HDDs with the 722 receiver? Did it format and work?
As internal or EHD ?
I guess you're asking about EHD, then you should check with your USB-SATA enclosure controller's manufacturer if it support 4K sector size drives.
Yes, external. The enclosure doesn't matter, it's formatting. Some PC O/S, mainly XP but linux too supposedly, can have formatting problems. I don't know what formatting scheme DN uses on their HDDs. Anyone know? Ext3 maybe?
Yes, it's Ext3.
The recordings are on the second and subsequent partitions in subfolders of the DishArc folder. there seems to be one subfolder, with an 8 hex digit label, for each recording, with four files in it.
Exactly matter ! That USB-SATA controller inside will translate real geometry to logical and convert those cmds from DVR to the drive. Matter, believe me.
I've got a 4K drive in another application formatted Ext3 that works fine so I'm guessing it will work with the 722 too.
Tell us how it will goes; ppl who did try such drive for DTV DVR gave up.
It'll probably be a couple of weeks before I try. I'll post results when I do.
Alright, after getting DN to tell me they would refund the fee if the drive didn't work I went for it. It took a couple of tries to get the receiver to find the drive for some reason but it found and formatted my 1TB WD green 4K sector drive. I copied a show to the drive and watched part of it.
Horray. After what I've read here and elsewhere about the 4K drives I didn't really expect it to work.
I think you did miss my point in post#5.
Before final conclusion I would transfer to and from the disk 10s recordings, just to be safe.
I've used the drive in another ext3 device without any problems so I'm not worried about it. I did transfer back and forth with the last thing I had the drive installed in. I only have a few things on my DVR right now so I can't transfer much. The transfer speed seemed fine to me. I don't think it will have alignment problems.
OK, sounds good - in contrary with DTV eSATA 4K HDD issues, you're using USB external drive. Lets see what in there - can you tell us what chip installed inside the box ?
I didn't use an enclosure. It's just an IDE/SATA to USB adapter and P/S I got on ebay for about $8 if I remember right.
If the receiver has a 500GB HDD and it only uses about 2GB per hour to record, why does it only hold 55 hours? I know the O/S and guide use some but it can't be anywhere near that much.
You missed my old posts where I did show partitioning of internal 250/320/500 GB drives.
If you're using simple adapter, the you can easy to tell us what chip it using ?
Old posts where? Link?
Chip # JM20337
A logo with JM in it.
Sorry, I don't remember all my 8K post's links . Try to search by the numbers and my nick/dish forum as a filter, perhaps a keyword "partition" could help.
Read the brief about JM20337, nothing stellar, old type - support only 1.5 Gbps; good to know it works fine with modern 4K drives.
