Read/Write corruption with large files.
For about a year now I’ve been using Clown BD (Thanks!) to make ISO files on one of my 2TB Hitachi HDS7220ALA330 drives. For speed, I Demux to "C" and Remux on "D" and then send the ImBurn ISO to "J", the 2TB Hitachi. It was only once in a great while (1 in 20 movies maybe) I’d see a glitch or graphic corruption while playing back a movie. Now that drive is full and I started using the second 2TB Hitachi drive "J" and every single move has graphic corruption at lest every five minutes or so.
I have only 2 SATA Hitachi HDS7220ALA330 2TB drives connected to a SY-PEX40016 SATA controller. Drive “J” and Drive “K”. With no RAID, only JBOD.
I also have other drives connected to the controller built into the motherboard. One is a 1TB drive “I”
I have been testing this for a few days now and if I create a large ISO file 10-40GB from the same source to each of the (I, J and K) drives each copy says that it was successful. So I have three ISO files that are all copied from the same source to each drive.
Now when I do a binary file compare between the file on drives “I” and “J” or “I” and “K” it says the file is the same almost every time but if I run the compare again without changing anything it sometimes says the file is different. So sometime it says the files are the same and sometime not when comparing the file on a drive that is on the motherboards SATA controller and one of the drives that is on the SY-PEX40016 controller.
Next, if I run the same file compare between drives “J” and “K” (both drives that are on the SY-PEX40016 controller) it always says the files are different. This is without changing anything and with the file compare between drives “I” and “J” or “I” and “K” showing that the files are the same.
The drives pass all other tests and I got a second set of cables but it still has the issue.
Next, I’m going to try and put the drives on the built in Intel controller.
My PC:
Gigabyte GA-X48DS5 motherboard
8GB of RAM
Windows 7 64bit with Service Pack 1
Just hoping someone else has dealt with this.
Thanks.
