Greed93 Posted December 22, 2015 Share Posted December 22, 2015 Hello guys, I've just bought a WD My book duo http://www.wdc.com/fr/products/products.aspx?id=1260 I was going to use RAID1 but I read that if data got corrupt,if there's bad sector in one drive it is mirrored to the other. Not a good thing. Is it better to use JBOD and copy the files from one hard drive to the other ? I'm a newbie for that so any help is much appreciated!

vibranium Posted December 22, 2015 Share Posted December 22, 2015 I assume that you want some kind of redundancy because your files are important, and you don't really care much for speed. If that's your scenario, yes go for RAID1. 28 minutes ago, Greed93 said: I was going to use RAID1 but I read that if data got corrupt,if there's bad sector in one drive it is mirrored to the other. Not a good thing. If the RAID controller is working properly, the bad sector will be flagged and there will be error correction or mitigation. Just make sure that before you start putting files on the MyBook, you flash it to the latest firmware from the support website. Link to comment Share on other sites More sharing options...
Greed93 Posted December 22, 2015 Author Share Posted December 22, 2015 Ok thank you One more question. If I use JBOD and one of the drives dies, is the other one still functionnal ? Link to comment Share on other sites More sharing options...
vibranium Posted December 23, 2015 Share Posted December 23, 2015 JBOD = 2 separate disks. I don't see why the other one wouldn't carry on working. Qualification 1 - But it actually depends on the controller. There are some el cheapo controllers that are terrible, especially in the past. Now, not so bad. Qualification 2 - If the failed drive fails spectacularly, e.g. short-circuit, then all bets are off. Link to comment Share on other sites More sharing options...
davmil Posted December 23, 2015 Share Posted December 23, 2015 Some useful tips here BUT nothing beats an off-line image backup; refreshed as often as you wouldn't mind re-keying everything since the last image. Also, consider RAID Level 0 depending on your goals. Simplier for the uninitiated. Link to comment Share on other sites More sharing options...
Greed93 Posted December 23, 2015 Author Share Posted December 23, 2015 I'll use JBOD and copy the important data from the disk one to the second disk. I'll gain much more space I'll also copy the important data to another external hard drive. Just to be safe. Link to comment Share on other sites More sharing options...

As usual, consistent practices are what makes it work. Link to comment Share on other sites More sharing options...
palmpre3 Posted December 26, 2015 Share Posted December 26, 2015 I would sacrifice the performance and go RAID5 for resilient and storage space. I don't do gaming anyway. Link to comment Share on other sites More sharing options...
