A Broken Western Digital 1TB Hard Disk

It is a WD10EXEZ SATA,64MB Cache 1.0TB hard disk. I bought it in the end of 2012. Now it is almost three years.

I found it is not working yesterday morning.  The Windows 7 can not found the hard drive when I boot up it. It can be found after a reboot.

But, some files are not able to access.

So I tried to do the backup all the important files. Most of the files can be copied to the backup media. The error of some missing files are shown as below.

I have to skip these kind of files to continue. And during the backup, the disk error shown randomly.

There is a error when I tried to resize the VirtualBox hard disk, or vdi file.

Replace SSD on Acer Aspire One ZG5

Acer Aspire One ZG5 has 8GB SSD. This SSD has poor performance as indicated on Wiki.

Intel Z-P230, model SSDPAMM0008G1. This SSD has been criticized for its slow read and write speed. Intel lists the drive’s maximum speeds as 38 MB/s read and 10 MB/s write.

The even worse issue is that the SSD on my netbook has a lot of errors.

So I was considering to replace it by a new SSD.

This is the one I took out from the netbook.

What is GPT

GPT stands for GUID Partition Table.
The widespread MBR partitioning scheme, dating from the early 1980s, imposed limitations which affect the use of modern hardware. Intel therefore developed a new partition-table format in the late 1990s as part of what eventually became UEFI. The GPT as of 2010 forms a subset of the UEFI specification.
To use GPT for partition, the system has to meet the following requirement.
Hardware:
New motherboard with UEFI support.
Software:
Linux has native support for it.
Windows 2008, Windows 7, only 64bit support it.

SSD: SLC vs MLC

Based Wikipedia, A solid-state drive (SSD) (sometimes improperly referred to as a “solid-state disk” or “electronic disk”) is a data storage device that uses integrated circuit assemblies as memory to store data persistently.
Yes, SSD disk has no moving parts. It is as quiet as nothing working.
SSDs use NAND flash chips. Within each of these chips are millions of cells. There are only two types of NAND cells today: single-layer (SLC) or multi-layer (MLC).
So, which one is better, SLC or MLC.

Diskeeper Pro Premier 2010

I downloaded the trial version of Diskeeper Pro Premier 2010 and installed it on my Desktop.
There are a few features I like.
New! IntelliWrite™ fragmentation prevention technology. IntelliWrite prevents up to 85% of the fragmentation every system suffers from. It intelligently writes contiguous files to the disk so system resources are not wasted creating fragmentation. The results? A whole new level of system speed and efficiency.
InvisiTasking® technology enables management-free defragmentation with zero management overhead and zero system overhead. Now improved for busy systems. Having to schedule defrag runs is now a thing of the past.

Actually I bought two items. One is the NAS enclosure, or Dlink DNS-323, 2-Bay Network Storage Enclosure. It is a very old product. Start to sell about two years ago. The other one is a Hard disk.
Western Digital WD15EADS Caviar Green 1.5TB. It is a SATA 32MB Cache 3.5IN Hard Drive.
I put one disk in it. In the future, if I need, I can add another 1.5TB in to double the capacity.

R-Drive III external hard disk adapter

I bought a adapter or converter which can convert an IDE hard disk or SATA disk to a USB external drive. If I need to test a HD, just connect it on R-Drive, and plug the usb to computer. The computer will recognize the HD as a external disk.

1. Connect laptop 2.5″ harddisk (IDE/SATA) to any computer via USB without power adaptor
2. Connect desktop 3.5″ harddisk (IDE/SATA) to any computer via USB with power adaptor
3. Connect CD-ROM/CD-RW/DVD-ROM/DVD-RW (IDE/SATA) to any computer with power adaptor.

I tested it with my 3.5″ 40GB Maxtor hard disk. It works on my Windows XP and O!play media player.

It is $20 plus tax.
