I'm having a problem with some files once copied to the DNS-323 becoming corrupted and unreadable. They are usually large video files, but have also been small jpg's as well.
I am using 2 Samsung 2TB drives (Spinpoint F3EG EcoGreen HDD 32M) configured as separate volumes. Volume 1 is my main drive and Volume 2 is a backup (I periodically run SyncBack to backup Vol 1 to Vol 2). I usually find out about the corrupted files when doing this backup from Vol 1 to Vol 2, as Syncback reports errors.
Logging on to the DNS-323 to check status doesn't reveal anything wrong with the drives. Running a scan disk on Volume 1 also doesn't show any errors. I am using firmware 1.08.
Can anyone help? I'm not sure if there is a problem with the DNS, the Samsung drives, Windows 7 copying data or something else?
-
Does the corruption occur only after using SyncBack? Does it occur on both drives?
-
To the first question, no. SyncBack alerts me to the problem, but before using SyncBack I have noticed the odd video file not playing all the way through (ie Windows Media Player hangs). I don't think SyncBack is causing the corruption.
I'm not sure if the problem occurs on Vol 2.
I just did another scan disk on Vol 1 and it failed. Can reformatting help or is it going to be a warranty claim on the hd do you think?

If you can put the drive in a computer and check it with the manufacturers diagnostics that will help diagnose a drive problem.

Finally got around to checking the drive in my PC with the Samsung diagnostic tools - it found a heap of errors so there is my problem. Going back to the shop today to replace it :)
That raises another issue - that I am returning a hard drive with personal information on it (ie family photos and home movies). It's a bit unsettling but the only other option is to forego my replacement and purchase a new drive. I did do a low level format using the Samsung tools, but I realise that the data would still be recoverable but someone who knows what they are doing.
-
A couple of passes of the low level formatting should be secure enough for most people. If not, just buy a new drive and keep the old one. 2TB drives are now $100 most places so the choice is yours security vs cost. There are free and commercial data wipe utilities available too.
Do you really think anyone would would steal the drive from the manufacturer and bother going through 100's of returned drives and spend days/weeks recovering data fragments in the hopes of finding something useful?
-
I seriously doubt that after a LLF anyone is going to go to the trouble of trying to extract your personal data. I think you read too many spy novels. :D

Thanks - feel better now :)

There's also the option of using a freeware tool called DBAN. It can use various methods to securly erase the disk with passes of random data. If it's good enough for the MOD it's probably good enough for us :)
