Seagate ST31500341AS 1.5TB

How bad are "no spin retries", anyone know?

Has Infrant stated that the 1.5 gb drives are approved yet?

Found the link for the approved drives -- still not approved:

Not sure if I want to chance messing up my support for this.. The notes are weird though..


Incompatibility Notes

WARNING: NETGEAR Support may deny support for issues due to using disks outside the compatibility list.

* Seagate ST31500341AS 1.5TB Barracuda 7200.11 - At this time the Seagate 1.5TB AS drives are being removed from the compatibility list. There appears to be a possible problem with streaming from these drives when write cache is enabled. We are working with Seagate to resolve this issue as soon as we can. Update: Seagate has released a firmware update that supposedly fixes this problem. See here for instructions on obtaining this firmware.

The SD1A firmware fixed my streaming/pausing issue. One of the jedis is running with them as well with good success if I remember correctly.

Buy today/tomorrow, get a 5 year warranty. Buy Saturday, get a 3 year warranty.

Nuts. I've got about 5 days of runtime on these drives and one of them just came up with a reallocated sector:
Reallocated Sector Count 1

That drive also has a Spin Retry Count of 1. Does anyone know if that stat is something to worry about?

One of the other drives also shows a Spin Retry Count of 2

Also, all of the drives show crazy things like: Head Flying Hours 208073985622136. I'm guessing that stat is a bug or improper reporting on the ReadyNAS.

I rely on this thing too much - I'll wait for the Netgear folks to bless it..

I bought four of these 1.5TB drives when I bought my ReadyNAS NV+ about ten days ago. Purchased them from NewEgg. All of them came with firmware CCJ1.

One of my four 1.5TB drives keeps generating error messages about sectors being reallocated. It has gone from 1 to 2 to 19 to 27 to 32 bad sectors in less than one week. Also, one of my other 1.5TB drives initially went from 0 to 2 during the first day or two of use but has held stable since. Today, I called NewEgg and said I thought I had two defective drives. Without any hesitation, the customer service rep offered to send me two new ones. The only hitch is that I first must return the two I have; NewEgg will ship the replacements to me only after it has received the original (defective) drives. Luckily, I had the foresight to order three of the drives from Amazon on 12/31. I was going to use two in a DLink NAS and keep the third as a spare. I'll now wait until I receive those drives (should be sometime next week) and then use them to replace the two drives in the ReadyNAS. I'm curious to see what firmware is on the drives I receive from Amazon.

Update: I pulled the disk with the reallocated sector and dropped it into a PC. I ran all of the tests in SeaTools on it, including the SMART test, short DST and long DST. All of them passed. So, it seems that SeaTools seems to ignore 1 reallocated sector... I guess I'll wait and see if it gets worse or contact the vendor and try to get it swapped out.

yeah, pretty sure I saw somewhere in this thread that seatools just overlooks reallocated sectors (and that they're reallocated from spare space on the drive) - can't remember if it was here or somewhere else.

I've got 1 of my 4 drives still holding steady with 1 reallocated sector. Did catch a 2nd spin retry on one of my other drives today, though... still driving these things into the ground so i'm becoming fairly confident at this point.

i have 3 v. CC1H drives, here is the results so far -

disk 1 - no problems
disk 2 - 1 spin retry count
disk 3 - 3 spin retries, 1 reallocated sector count,

i still haven't installed one drive because i need a way to update the firmware from CC1G to CC1H. I have a macbook pro which makes it difficult.

anyway, i'm using the drives without problem so far.
