Are my HDDs dying?

[StormClaw]

I have a NAS with 4 disk array, all stretched into RAID 0
2 of the disks are fully good and the other 2 are acting up. Please help me determine if the replacement is needed:

Disk 1: QNAP software reports some SMART problems:

Disk 2 is having read/write problems and QNAP software detected about 200 bad blocks:

What do?

The drive has had 3975 sectors automatically replaced from its spare pool over its lifetime. This may indicate a very real problem. See if the number continues to grow (over a short period of time) or you see any current pending sectors.

Also with raid 0 I hope you have a backup of your qnap.

i'd be backing stuff up next boot.
If it starts being slow in the BIOS..back up ASAP.

RAID0 on a 4 bay Qnap is madness bro.

Should be rockin' RAID10 if you wanted speed.

But yeah unfortunately you stand a very real chance of loosing all your data at any moment. The only way to save it at this point is a full backup to some other device.

The data is not extremely important, it's movies only.

But i wanted a REAID0 for bigger capacity as each movie is about 25GB.

I recommend you get a couple of 4TB external drives ASAP to backup the raid 0.

forget the pending sectors, you have 4000 realocated sectors, backup yr raid and dismantle it asap
that drive is gone
waranty is probably expired ( 20k poweronhours ) so throw it out

throw it out? bah, once it's replaced leave it in there and crank up the workload to try and induce a failure just to see what happens
failing that take it apart for the nice magnets and platters. (they throw well)
