Western Digital RE vs SE
From: http://www.neweggbusiness.com/product/product.aspx?item=9b-22-236-352
If you are looking at this hard drive, you may be wondering what it offers beyond identical capacity 7200 rpm drives that cost less. Specifically, the Western Digital Black and SE drives are candidates. The Black drives are very similar to enterprise class drives right down to the 5 year warranty. The big difference is drives like the WD2000FYYZ have TLER (Time Limited Error Recovery). In layman’s terms, if an error occurs with the hard drive in a RAID array, a drive will most likely not be able to recover and the RAID may need to be rebuilt. Without TLER, another error during RAID rebuilding results in all data being lost. So, TLER is why you may not want a Black edition drive. For the SE model Western Digital drives which also feature TLER, the big difference is that the SE has a much lower MTBF (800,000 hours vs. 1,400,000 hours) and the non-recoverable read errors per bits read is also not as good (<10 in 10^15 vs. <10 in 10^16). Performance-wise, I ran some benchmarks and according to ATTO I’m getting a little over 160 MB/s for both read and write. That’s pretty good for a mechanical drive, although it is less than the advertised 171 MB/s listed on the spec sheet. I’ve read other reviews saying this drive is loud during read and write seeks. Subjectively, I find it equal in acoustics to my Western Digital Black drive (FALS). Yes it’s audible, but if silence is your priority then you should be looking at a different model to begin with.” — Robert P. 10/9/2013
TLER and OS drives
From: http://www.pcguide.com/vb/showthread.php?88925-Does-TLER-do-any-good-for-software-RAID-1
While I would still prefer to use something like WD's Red drives for software-based RAID, you could use standard consumer-grade SATA drives and be just fine. Any errors your drives encounter will cause the array to take a bit longer to respond, but RAID 1 is computationally simple and such delays would not be too bad considering the alternative. If this RAID 1 array is for an OS install, I would recommend using standard SATA drives (you want that self-healing!). If this RAID 1 array is for storing data, I would recommend TLER (do not forget to turn it on!). If this RAID 1 array is for a dedicated file server, I would recommend Red drives (you want error reporting here).
Support for WD desktop drives in a RAID 0 or RAID 1 configuration
From: http://wdc.custhelp.com/app/answers/detail/a_id/996
WD desktop hard drives (WD Blue, Green, or Black) have been tested and are recommended for consumer RAID applications when using the drives in a RAID 0 (Stripe) or RAID 1 (Mirror) configuration. However, there are several things to keep in mind when setting up a RAID with these drives: WD only recommends using a Desktop drive in a RAID array with no more than two (2) drives (Raid 0 or Raid 1 only).

Removing OSX partitions in windows
Disk Manager will not help in windows 7 use dos command diskpart
- On the command prompt type diskpart and answer to any possible UAC prompt.
- On the new diskpart prompt, type list disk. Note the Disk ### column.
- Type, select disk ### (with ### being the disk you wish to delete.
- Usually the disk with partition 0 with a size of 200 MB) NOTE: The disk may not show the 200MB partition in the disk list in Diskpart even if it exists.
- Finish by typing, clean.
- Type exit to exit diskpart
formating large drive for linux windows
In Mac OS X, use the following commands to format your large (no 4Gb limit) hard drive in FAT32.
It will be readable and writable on Linux, Mac OS X et Windows.
First, identify the disk you want to format with this command:
$ diskutil list
/dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *232.9 Gi disk0 1: EFI 200.0 Mi disk0s1 2: Apple_HFS Mac_HD 39.9 Gi disk0s2 3: Apple_HFS Data 192.6 Gi disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *1.9 Gi disk1 1: DOS_FAT_32 CORSAIR 1.9 Gi disk1s1 $ diskutil partitionDisk /dev/disk1 MBRFormat "MS-DOS FAT32" "Millenium Falcon" 1.9G $ man diskutil diskutil partitionDisk /dev/disk2 MBRFormat "MS-DOS FAT32" "ScaHD" 1.0TB

Quick facts about Windows and 3TB drives:
Windows 7 and Vista support GPT 3TB single partitions Windows 7 and Vista can only boot GPT on systems with UEFI BIOS Windows 7 and Vista can mount a GPT non-booting data drive Intel RST device drivers before v10.1 do not support 3TB disk drives Windows systems with Legacy BIOS and MBR boot drives are limited to 2.2TB partitions Windows XP does not support GPT Windows XP sees a 3TB drive as 800GB on boot or data drives DiscWizard software can install a device driver which opens the full capacity of a 3TB. You can use it to create a second partition for the capacity above 2.2TB
