I apologize for the delay in providing updates on the Exchange Program, Rev B shipping status, next Service Release, etc. The start to year was very hectic with Macworld, CES, changes in the economy and other unexpected events. In addition I have been battling a rash of sinus infections which are a result of my allergies. It has not kept me from the office but has affected my energy level and time spent on other activities. With me finally getting over the last infection, I am nearly 100 percent again and will be back on the boards permanently. As usual, email is the best way to reached me (email@example.com) if I am absent. Exchange Program
Emails will go out next Monday the 16th of March. The emails will be sent out over a period of several days so the Tech Support RMA persons are not swapped with handling the exchanges. RMA will be handled between the US and European Locations. Instructions will be included in Email.Preparation
1. Backup all critical data. The recovery function is designed to recover array information from the drives in the event the array is placed into a new enclosure. This process works well but nothing is 100 percent and drives with poor integrity can complicate the process. Frankly, you should always have a backup of all data and never a single copy or central storage. In future firmware release we will provide function to backup to USB attached drives. The upcoming NS4600 will allow backup to USB and eSATA attached drives.
2. Make sure your Rev A model is on SR5 Firmware 1.5.3 or 1.5.7. No exceptions as we do not have time to support array roam with older versions on the new hardware.
3. Those using Seagate Desktop Class (Barracuda AS 7200.11 and 7200.12) and Barracuda ES.2 Drives, not sure if you are aware of the current issue with the drives becoming inaccessible on power cycle, but I advise NOT to power cycle the NAS until you have a good backup of your data. If more than one drive becomes inaccessible on reboot (power cycle) you will have an offline array resulting in data loss. Once you have backup of your data, I advise updating the drives to the Firmware Level Seagate has posted on their Website.
ES.2 Firmware is here (please read very carefully and pay attention to part numbers): http://seagate.custkb.com/seagate/cr...ilite=firmware
Barracuda 7200.11 is here (please read very carefully and pay attention to part numbers): http://seagate.custkb.com/seagate/cr...ilite=firmwarehttp://seagate.custkb.com/seagate/cr...irmware-Update
If you are using Seagate Hard Drives branded as Maxtor or Quantum Hard Drives, please check the Seagate Support site for firmware update.Removal of Seagate and Samsung Desktop Drives from the AVL (All NAS Products)
As of a few weeks ago I removed the Seagate and Samsung Desktop Drives from the NAS AVL. Desktop Drives are not designed to be used in RAID Arrays. Desktop Class SATA Drives lack several key characteristics that are present in Enterprise SATA Drives. These drives do not support TLER (Time Limited Error Recovery), have lower MTBF (Mean Time Between Failure), have lower Duty Cycles and typically lack RV Sensor (Rotational Vibration). They are not ideal for running in RAID solutions and excessive bad sectors on multiple disks (especially without TLER) can result in severe errors to the filesystem including data loss as RAID 5 can only handle errors on a single disk at a time. I discussed the decision with both Seagate and Samsung; both agreed that removing is in the best interest of the customer (you). WD and Hitachi Desktop Drives will remain on the list. If you are using any of the removed hard drives we will still support you but moving forward all new or existing customers replacing drives should use Seagate and Samsung Enterprise Class Drives only.NS4300N Rev B Availability in the Channel and Retail
NS4300N Rev B is now available in the channel and retail. The following Retailers below have the units in stock. Rev B has new blue retail packaging (see attached image).
New EggBTW: Some Fry's stores may still have inventory of Rev A. As of late Jan Fry's started to receive Rev B. To sure to look for the new "blue" retail box if you must have Rev B. If the NAS is going into a closet, garage or other space where noise is no issue, then Rev A is fine.
In addition to resolving the Fan Control issue, we also changed the power supply fan. Rev B also features improved LED.
For those of you in Europe, APAC and the Lands Down Under, I will have news on retailers for you in a few days.DLNA/UPNP Plug-in Scan issues
Two issues exist in the current build 01.01.0000.05 of the DLNA Plug-in:
1. Scan process halts when a bad media file is encountered. The scan engine was being way too tight and would abort on bad media. For reference, about 75% of all media has metadata errors and or encoding errors that should prevent the file from playback on any media player (software or hardware). Just about every MP will ignore most errors and playback the file. I have been able to reproduce this will several pieces of media from customers and others I know. Myself, I have never had this problem as I encode all of my own Divx and MKV/H.264 Content and all of my music comes from my own CD's or is purchased from Amazon MP3 store or Rhapsody MP3 Store. The majority of the bad content comes from the internet or friends (unknown source - therefore integrity of files is questionable). The scan engine has been updated to ignore this condition. A beta version (v01.01.0000.06) will be posted later this week. If you want the version sooner, please email me at firstname.lastname@example.org
If you continue to experience problems with the scan engine stopping (so far our testing has been good), please contact me so we can work on the issue together.
2. Scan Engine was not optimized for very large libraries. Response times became an issue with the limited power of the SoC used in the NAS and cause the engine to stop. This has pretty much been resolved in v01.01.0000.06. Again, will be posted later this week and I can be contact to receive earlier.
NOTE: Remove OLD VERSION FIRST, then install new version.
I will post more shortly on the next Service Release and details on the NS4600(performance is damn good) and our first DAS, the DS4300efu (quad interface - USB 2.0, eSATA and Firewire 400/800).
