Solusi Untuk Performa Wdc 64mb cache yg lamban DI WIN XP

[HugoBoss]

Tweet

baru 2 ini saya menjual beberapa hdisk wdc 64mb cache.
ternyata ada beberapa customer yg mengeluh
kalau hdisk baru ini lambat kinerjanya, setelah saya selidiki di berbagai web, ditemukan jawabannya

1. ternyata wdc dengan cache 64mb ini mengalami
masalah penurunan performa apabila dijalankan di WIN XP.
hal ini hanya terjadi di winxp baik 32bit maupun 64bit , sedangkan win7 dan vista tidak ada masalah

2. Solusi untuk masalah ini

anda harus mengunakan jumper (yg disayangkan pihak dari wdc sendiri tidak menyertakan jumper ini dlm paket penjualnnya)

jumper ini dipasang di pin 7 dan 8 pada hdisk tsb




Pinnya dipasang di paling kiri

contoh gambar hdisk wdc 64mb cache, perhatikan posisi pin 7 dan 8 yg ditulis( ada di ujung kiri)

JUMPER INI HARUS DIPASANG SEBELUM ANDA MEMFORMAT HDISK.
JGN DIPASANG SETELAH HDISK DIFORMAT.

Solusi alternatif tanpa jumper

anda bisa mencoba install software dari wdc, kemudian dirun
(JGN JALANKAN SOFTWARE INI APABILA ANDA SUDAH MEMAKAI JUMPER, KARENA HDISK BS RUSAK)

What Operating Systems Are Affected

Now that we’ve dealt with what 4K sectors are, why Western Digital and other drive manufacturers are switching to them, and what the potential pitfalls of 512B emulation are, we can look at the specific cases where there are potential problems.

The big problem is that while the first work on 4KB sectors started in 1998, it wasn’t until after the launch of Windows XP that the matter came to a head. As a result the 5.x versions of Windows (2K, XP, 2K3, WHS) have no concept of 4KB sectors. Even though all operating systems will be seeing 512B sectors through the use of emulation technology on the drive controller, out of Windows only Win 6.x (Vista, 2008, Win7) and later have been programmed to take in to account the alignment issues we mentioned earlier. Win 5.xx in particular has a nasty habit of starting the first partition at LBA 63, which is 1 512B sector misaligned from a 4K sector boundary. In essence, the issue is that Win 5.x will always create a misaligned first partition and will have poor default performance as a result.

Although Win 5.x is the primary victim here, other versions of Windows can also be affected in edge cases. Along with the need for 4K-aware operating systems, drive imaging software needs to be 4K-aware. Otherwise such imaging software may inadvertently create misaligned partitions too. As such, Win 6.x is also affected by alignment issues when imaging software is used, as some (and perhaps all?) imaging products currently available will write misaligned partitions and/or clusters.



Notably, Linux and Mac OS X are not affected by this issue. Western Digital has tested both of these operating systems, and officially classifies them as not-affected. Ultimately we suspect that if you went back far enough you could find older versions of these OSes that are affected, but unlike Win 5.xx, there’s not a significant legacy user base to worry about. Along these lines, Linux and Mac OS X drive imaging products are similarly unaffected. In their testing, imaging tools such as SuperDuper didn’t run in to any alignment issues, so Linux and Mac OS X users are not affected in any way by 4K sectors. It’s only Windows and Windows imaging products that are affected.

In order to solve the misalignment issue, Western Digital is offering two solutions. The first solution for correcting misaligned partitions is specifically geared towards Win 5.x, and that is an option on the drive itself to use an offset. Through the jumpering of pins 7 and 8 on an Advanced Format drive, the drive controller will use a +1 offset, resolving Win 5.xx’s insistence on starting the first partition at LBA 63 by actually starting it at LBA 64, an aligned position. This is exactly the kind of crude hack it sounds like since it means the operating system is no longer writing to the sector it thinks its writing to, but it’s simple to activate and effective in solving the issue so long as only a single partition is being used. If multiple partitions are being used, then this offset cannot be used as it can negatively impact the later partitions. The offset can also not be removed without repartitioning the drive, as the removal of the offset would break the partition table.


The second method of resolving misaligned partitions is through the use of Western Digital’s WD Align utility, which moves a partition and its data from a misaligned position to an aligned position. This is the recommended solution for using multiple partitions under Win 5.xx, along with correcting any misaligned partitions generated by imaging software. For that matter we’d consider it the recommended solution for single-partition drives being used under Win 5.x too, as there’s no need to worry about offsets and breaking the partition table.

seputar pertanyaan mengenai hal ini


Q: What does Advanced Formatting mean to me?
A: Advanced formatting optimizes hard drives to take advantage of the capabilities of newer operating systems. This capability enables hard disk drive manufacturers the ability to design larger capacity hard drives, now and into the future.

Q: What are the benefits of Advanced Formatting?
A: Advanced Formatting enables hard drive companies to read and write more data into the same available space on the hard drive.

Q: Can I install an Advanced Format hard drive in my system?
A: New drives from WD are optimized for operation with Windows 7, Windows Vista and Mac OS X Tiger, Leopard, Snow Leopard. If you are attempting a clean install of an Advanced Format hard drive into a system running one of the Operating Systems listed above the installation process follows standard procedure. For older operating systems such as Windows XP, and for users using cloning software, users must run the WD Align utility to achieve the full performance of the drive. (see table for configuration details)

Q: What is WD Align utility software?
A: The WD Align utility enables older operating systems to operate at full performance on Advanced Format hard drives.

Q: How long will running the WD Align utility take?
A: It will vary based on your operating system and how much data is on the disk, but the WD Align utility should take about 20 minutes to complete on freshly installed drive images with no data files. We recommend disabling Power Management prior to starting the partitioning alignment process. Please click here for further instructions.

Q: Does the WD Align utility have to be run again if a drive is reformatted?
A: No, users will only need to run WD Align one time after initially installing Windows XP. Once Windows XP has been aligned, it will stay aligned even if the drive is reformatted or many files are added or removed.

Q: What models utilize Advance Format technology?
A: Some models of the WD Caviar Green are built using Advanced Format. Over time more models and capacities will be added. WD drives with Advanced Format include special installation information on the drive label so be sure to read the label on your drive before installing it.

Q: Can I install my Advanced Format Drive into a USB enclosure?
A: Yes, you may install your Advanced Format Drive into a USB enclosure. Please click here for further installation instructions.

jadi jgn langsung menjudge hdisk anda rusak

betul pak harus dipasang jumper, ingat ya
jumpernya harus dipasang sebelum diformat.
jgn dipasang setelah format. thanks

oh begitu toh, padahal udah terlanjur diinstallin sama dia.
oke ntar aku suruh dia buat instal ulang aja deh, tapi kasian jg kalo ga dapet jumpernya ya.
payah juga sih, masa cuma jumper doang ga disediain sama WDCnya. :laugh:

Kalo hd-nya ada dua atau lebih dan os-nya diinstal di hd yg lainnya, ya tinggal dihapus partisi hd wdc-nya dgn software partisi manager (seperti: bawaan window, acronis, paragon, dll)

Om Hugo klo dipasang jumper aja terus ga usah dijalanin Software WDCnya bisa ga..

Klo baca diketerangan yg terdapat di hd wdc-nya......dijumper kalo partisinya cuma satu (pilih salah satu, dijumper ato pake software) tapi klo partisi lebih dari satu sih cuma pake software doank. cmiiw

thanks bro, bener sekali kalo anda sudah pake jumper tidak usah install software wdc lagi, pilih salah satu aja.
