RNDU4000 after update from FW4 to FW6 extremely slow - any suggestions/solutions?
Hi All, I´m new here and would really appreciate your help and maybe some hints. Got me a used Netgear RNDU4000 (ReadyNAS Ultra 4) from a friend with FW4.2.31 installed. After reading a bit I th...

the re-sync of the 4 HDDs with 1.5TB each was about 1% after several hours... this was very much faster with old FW 4.2.
Has the resync process finished now? The NAS will be very slow during the resync, but should pick up speed afterwards.
Normally I'd expect a 4x1.5 TB resync to complete fairly quickly (it will take hours, but not days).
One possibility is that one of the disks is beginning to fail. It'd be useful to download the log zip file from the admin web ui and look at smart stats in disk_info.log.

The new firmware requires more memory. Can this confirm someone ?
4: Does G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Memory F2-6400CL5D-4GBNT fit and solve the problem?
We do recommend more memory here, as folks have run into out-of-memory conditions on their NAS.
However, the G.SKILL won't work on an ultra 4. It has only one memory slot, and it is 200-Pin. A single 2 GB module of 200-Pin DDR2 SODIMM DDR2 667 (PC2 5300) should work (doubling your current RAM).
You can open the chassis and look at the current RAM module, and google its specs (powering down of course). But wait for the resync to finish.

6. any way to go back to FW 4.x instead of throwing it into the trash at least?
You can revert, but I think something is wrong - and needs to be sorted out.
