Dear All,
I bought my 343 and for the beginning one 1TB WD drive. The hard drive configuration menu shows the details:
Disk  Vendor  Model  Serial Number   Size 
1  WDC  WD10EARS-00Y5B1  WD-WMAV51340528   1000 GB 
Of course I could chose Standard option. 
1.) For file system I tried ext3 first. The initializing phase and the format phase finished. Here is the result:
"FORMAT RESULTS :
Change the hard drive configuration or format the newly inserted hard drive(s). Notice that your data will be erased during the process.
 Hard Drive(s) Formatting Failure (Error Code:17)."
2.) After several failed prcedure with ext3 I chosen ext2. After the initializing I got this:
"Change the hard drive configuration or format the newly inserted hard drive(s). Notice that your data will be erased during the process.
 
 Hard Drive(s) Formatting Failure (Error Code:119)."
Questions:
-What does it mean error code: 17? Or 119? 
-Is the mentioned WD disk is comatible with DNS343? 
-Where could I find a new compatibility list for DNS343?
-I wasn't able to format the disk in desktop PC to ext2-ext3 neither ntfs. Should check it somehow? 
Thank you for any help in advance.
Regards
