RAID 5E with an E that stands for Enhanced, RAID 5E is a RAID 5 array with a hot spare drive that is actively used in the array operations. In a traditional RAID 5 configuration with a hot spare, the hot spare drive sits next to the array waiting for a drive to fail, at which point the hot spare is made available and the array rebuilds the data set with the new hardware. There are some advantages to this operational method:
There are a few disadvantages associated with RAID 5E as well:
The capacity of a RAID 5E array is exactly the same as the capacity of a RAID 5 array that contains a hot spare. In such a scenario, you would “lose” two disks’ worth of capacity — one disk’s worth for parity and another for the hot spare. Due to this fact, RAID 5E requires that you use a minimum of four drives, and up to eight or 16 drives can be supported in a single array, depending on the controller. The main difference between RAID 5 and RAID 5E is that the drive that would have been used as a hot spare in RAID 5 cannot be shared with another RAID 5 array; so that could affect the total amount of storage overhead if you have multiple RAID 5 arrays on your system. Figure A gives you a look at a RAID 5E array consisting of five drives. Take note that the “Empty” space in this figure is shown at the end of the array.

When a drive in a RAID 5E array fails, the data that was on the failed drive is rebuilt into the empty space at the end of the array, as shown in Figure B. When the failed drive is replaced, the array is once again expanded to return the array to the original state.

A screen of mine burnt out, and was replaced with a screen of lower resolution. It works in safe mode as that is in 800×600 resolution, but when I try to boot to normal mode, it fails. Is there a way to change the resolution for normal mode in safe mode? Solution: Once you’re in…
As we know: Seagate Barracuda 7200.9 HDD can’t spin; board/chip be burnt; interface broken; etc. These problems are caused by PCB malfunction. Swap PCB of your Seagate Barracuda 7200.9 hard drives can resolve the problems.
1. Seagate Barracuda 7200.9 Hard Drives PCB Buying Guide:
For Seagate HDD, just need the donor PCB has the same board number as yours.
* Seagate Hard Drive PCB Swap
2. Before Seagate Barracuda 7200.9 HDD PCB Swap you should know:
1. Most PCB’s BIOS chip(ROM Chip) store the unique information. We need change the BIOS form original PCB to replacement PCB, in order to make the replacement PCB compatible with the HDD. The 8pins (4 pins on each sides) with 25P05VP、25P10VP、25F512、25F1024、25F1024AN、SST25VF512、SST25VF010, etc. are the BIOS Chip.
Tips: Most of the TV/Phone Repair Shop can offer these services for just $5-%20
* Hard Drive PCB Swap: Change BIOS Chip, Main Chip
2. Some PCB don’t have separate BIOS. The BIOS be integrated on the Main Controller IC(The biggest chip on the board, also named Main Chip). We should exchange the Main Controller IC to let the HDD be recognized.
