If the data can be read successfully, force online other disks, and then rebuild RAID. If the damaged SCSI card causes RAID configuration information loss, replace it with a new SCSI card, and then try to read RAID configuration information from disk (Need support from RAID array).
Bear in mind, though, that you won't get any help if you happen to lose the password. I personally use toys from Kingwin like those on this page:. Lots of firms make things like these. Fit in a 5.25 inch drive bay, hold 3.5 inch drives. Has a latch to hold the 3.5 inch drive in place. 
The power and sata cables attach to the bay device. When you put a drive in it, the drive is connected to the power and sata.
Mac Backup
Sure, you could leave two drives in the dock, but it's more efficient to use external drives if you want always-on backups. A hard drive docking station is a great device if you want to use a number of backup drives to store off-site. (I use one with a small drive to clone my iMac's internal SSD.) There's one more reason to own a drive dock.
As mentioned earlier, RAID uses two or more hard disks to ensure the data is safely stored, even if a drive failure occurs so you’re able to swap out a faulty drive if it were to fail. This is an important consideration in your backup strategy, but raises the costs more than using a simple external drive. Another benefit of NAS is that you can often perform other tasks with the device, since it’s effectively a small server. Some NAS devices can run media streaming services like, or can offer remote file access. What to look out for Home NAS devices typically come in two-drive or four-drive options, depending on the level of RAID protection you want and amount of storage you require. While the two-drive options are cheaper, I chose something with four for peace-of-mind, since data can only grow in size.
But you don't get all the capacity of the drives, because of this protection. For example, if you have three 4 TB drives in a unit, you'll get 8 TB capacity with RAID 5. With five such drives, you'll get 16 TB.
Making an informed choice on the best RAID implementation, on the other hand, is not something that should be done without a good understanding of the hardware and software under the hood. Few photographers are well equipped to make this decision properly. If you plan to use the drive for video editing, however, seek out the help of an informed professional who can ensure the drive meets the performance requirements for HD video workflows. • It’s generally much quicker and easier to upgrade capacity with JBOD. Fosters home for imaginary friends mac x reader. A traditional RAID setup must be rebuilt completely (all data moved off, all new drives installed) to upgrade storage size. This makes the upgrade process a difficult, time-consuming, and possibly dangerous process.
