Hard Disk Drive Specification in Bios

In standard CMOS Feratures in the Bios, you can manually input the Hard drive configuration and specification. On my two PATA disks, all of the options like are present, but when I select my SATA Hitachi 7K250 160GB drive only the Type and Maximum Capacity are present. There is no way I can enable 32 Bit Transfer Mode at all. I was just wondering if this is a BIOS problem or the BIOS just does this thing when a SATA drive is installed.

What do you mean "run over"? Is it similar to Bios not being able to detect the capacity of drives larger than 137GB w/out Service Pack 1?

Lenovo ThinkPad X131e Replacement Hard Disk Drive Specifications

I have recently been given a Lenovo ThinkPad X131e 3368-2GU. I notice that the internal 320GB 2.5" SATA Seagate Momentus Thin HDD is a slim height 7mm model. I would like to upgrade internal storage to 1TB or more. Do I have to replace this HDD with another 7mm model or will any 2.5" SATA HDD work? Any other replacement HDD requirements of which I should be aware?
Thanks for any assistance!
Solved!

Tryed by myself , the 9.5mm doesn't fit , 7mm works perfectly

Arch: Install to & run from External USB Hard Disk Drive (HDD)

I wanted to play with ArchLinux 2009.02, but replacing the existing Debian-Lenny on the laptop's HDD wasn't an option. So I experimented with installing Arch on an external USB Hard Disk Drive.
I have tried to make this "newbie-friendly", so I hope the more experienced will forgive the detail.
Materials:
Three year old Dell Inspiron 6000
CPU = 2.0 GHz Pentium
RAM = 2.0 GB
Internal HDD = 80 GB
Internal CD/DVD R/RW
External USB HDD = Freecom FHD-2 Pro 80 GB
Archlinux 2009.02 install CD
Steps to install:
1. I put the Archlinux install CD in the drive and connected the external 80 GB HDD in the USB port.
2. When the Dell laptop was booted, I pressed F2 to enter the BIOS setup. I edited the boot sequence to the following:
Internal CD/DVD
External USB device
Internal HDD
On the Dell, you can also press F12 to select the preferred boot device for that boot.
3. I started the laptop and the Archlinux installation menu came up and I proceeded with installation following the "Official Arch Linux Install Guide" and the "Beginners Guide".
4. Used km to change to UK keyboard layout and then began the installer script (/arch/setup). I was installing from the core CD so I skipped the network steps.
5. HDD preparation.
This was fairly straightforward with two cautions:
(a) Make very sure that the external HDD (sdb) is selected for the operations.
(b) Remember to set the Bootable Flag for the first (/) partition on the HDD.
I chose 20 GB for /, 2 GB for swap and the remainder for /home.
6. The package selection and installation was fairly straightforward.
7. Configuration of System
This was section was straightforward with one warning:
USB had to be added to the HOOKS in the /etc/mkinitcpio.conf file!
I found this to be essential for my external USB HDD to function as a bootable device. Otherwise I got the same sorts of errors relating to unrecognisable file system types that other people have reported in the forum.
The relevant line from the end of the edited /etc/mkinitcpio.conf file is below:
HOOKS="base udev autodetect pata scsi sata usb filesystems"
8. Installation of GRUB was the other point where caution and/or correction was necessary.
When it asked where GRUB should be installed, I had to select sdb (my external USB HDD) and not any of the particular partitions on sdb. If the root partition sdb1 was selected then the laptop won't boot from the external USB HDD.
The GRUB /boot/grub/menu.lst as written by the installation routine specifies hd(1,0) which doesn't work when you try to reboot from the external USB HDD. When you boot Arch from the external USB HDD, as far as Arch is concerned - at that point in time - the external USB HDD is the first drive in the system. To fix this:
(a) When the Arch boot menu comes up, press e to edit the grub entries.
(b) Change the first line to hd(0,0)
(c) To the end of the kernel line add rootdelay=8
(d) Press b to boot the system with these temporary corrections.
(e) Once your Arch system has booted, edit the /boot/grub/menu.lst to make the above changes permanent.
The relevant portion of my /boot/grub/menu.lst looks like the following:
# (0) Arch Linux
title Arch Linux
root (hd0,0)
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/... ro rootdelay=8
initrd /boot/kernel26.img
# (1) Arch Linux
title Arch Linux Fallback
root (hd0,0)
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/... ro rootdelay=8
initrd /boot/kernel26-fallback.img
9. The laptop happily and consistently boots Arch Linux from the external USB HDD when it's plugged in before startup/booting.
Running Arch from the external USB HDD seems as quick as running Debian from the internal HDD.
So if there is a performance penalty associated with using an external USB HDD, my wife and I haven't noticed.
In summary, the three essential points to address during installation to an external USB HDD are:
Remember to set the bootable flag for the first partition.
Add USB to the HOOKS for /etc/mkinitcpio.conf file.
Correct the /etc/grub/menu.lst file.
I hope this is helpful.
Ted

Hi Rookie,
As you say, it is worth remembering the rootfstype= option for the kernel line just in case someone still has problems with GRUB after making all the other changes.
I was working with the most recent Arch 2009.2 release.
I only got messages about unrecognisable file system type when I tried booting with the "stock" or "as-installed" GRUB (before I edited /boot/grub/menu.lst). After editing /boot/grub/menu.lst to identify the drive correctly and add rootdelay, GRUB was able to do the rest and everything worked OK without any error messages.
Best wishes,
Ted

Mac OSX wont reognise my internal hard disk drive

I have a problem where for some reason when I start up my Macbook Pro (intel core duo) it does not detect the internal hard disk drive at all. I have run a hardware test and it shows no problems whatsoever. I have tried resetting the PRAM etc and to no avail. Yesterday the system hung and I tried to force quit and it wouldn't do anything so eventually I held down the power key and when it tried to reboot this is the problem I was faced with (it would boot up with the "no entry" sign). I accepted complete defeat and went to completely re-install OSX however it doesn't even show the internal hard drive when I wait for it to give me install destinations. I had tried seeing the hard drive through disk utility however it only shows the install DVD and that's it in the sidebar. I resigned myself further to thinking either the logic board or the HDD had packed in all and I took it round to my brother in law to see if there is anything he could do without opening the machine (he is Oxford educated and writes programmes etc so is very knowledgable), now this is the part that has miffed us both, he started it up using a Linux disc and once running, Linux see's the hard drive with no problems. He has been able to access the HDD with absolutely no problems under Linux both reading and writing to it. I even took my Mac Mini round and he booted them both up in Linux and completely copied Mac OSX from the mini to the macbook pro but still when I try booting up its as if the HDD isn't even there. Why can Linux see the drive and not Mac OSX? Please don't be affraid to get very technical in your answers as they may mean nothing to me but will probably all make sense to my brother in Law. Any sugestions at all would be greatly accepted.

Dear mcdkev,
You guys may have made a big error cloning the Mini HD into the MBP. They both have very different drivers and hardware settings and their OS X versions are customized to fit the hardware. That is why each mac comes with it's own version of OS X and their backup disks. That's a reason why it did not work.
Ok, so now that you do not have any of the original info on the MBP try the following:
Use linux to scan the disk surface & repair any problems.
Reformat the drive as DOS or FAT 32. (I wouldn't go into any linux specific format unless you can "Apple" format it, which I don't think linux has that option.)
Now, the MBP should be able to see it's drive...
boot from the OS X DVD , from the Utilities menu choose Disk Utilities, partition the drive as GUI file system (in case the linux format made the drive a "system boot record", you do not want that... )
Then format the drive as "OS X Extended Journaled"
Now go back to install and install your original basic set of OS X (the factory default).
*If nothing works, please do take your MBP to the Apple store or to a certified tech before you do more damage to the drive and it becomes unusable ...*

Verify physical hard disk drive health MCS 7825-H3 that installed CUCM inside it

Hi Everyone,
I have Cisco MCS 7825-3 that installed CUCM ver 6.1.1 inside it. A few days ago the system was crashed and have been recovered. And the symtomp why the system crashed is because corrupted hard disk drive. Now the system is running well.
I want to verify the health status of hard disk drive MCS 7825. The logical drive is RAID 1 with 2 chunks (channel 0,1 and channel 0,2). So that i did the test to shut down the cucm and unmount on of the physical hard disk drive. After that i power on the server and running the system with just 1 hard disk drive (example just channel 0,1 and after verify channel i do the same task with channel 0,2). With just 1 hard disk drive if i show hardware in cucm cli , it showed that status of logical drive is degraded. But the system can run well (IP Phone registered and can do pbx features). And after do verify test with 1 hard disk drive, i mount the physical hard disk drive again so that the system running with all of hard disk drive mounted (2 chunks).
At first it showed in cucm cli that status of logical drive is degraded, but with current operation rebuild (indicated RAID 1 is rebuild again by the system). After up to 1 hour the process finished and the status of logical drive is optimal again.
The question i wanna ask, is there any method to know if the health of physical hard disk drive of MCS good or not beside the task i have done ?
Maybe we can show in the BIOS or cucm cli because i didnt find diagnose of physical drive in cucm cli but it can diagnose status of RAID, hard disk space and list file in hard disk drive.
Thanks for your help.

Hard disk drive for A20P

Just to know which maxi hard disk drive size is able to run my A20P
ThinkPad A20p - PIII 700 MHz (256KB) 512MB RAM Size of original HDD:18.0GB
Thanks for help

Your A20p will take on a significantly larger hard drive, I've had a 60Gb in one of my past ones and it worked fine. Theoretically, you should be able to install the largest available PATA drive (currently 250Gb), but I remember reading somewhere that there might be a BIOS limit at 137Gb.
Anyway, an 80, 100 or 120Gb HDD should work just fine even with the aforementioned (unverified by myself) limit.

Hard disk drive retrieval after drinks spill?

My son spilt liquid on his MacBook Pro and the keyboard and power switch have gone so it's not worth repairing and I've bought a new MacBook.
However he wants to retrieve some data from the old hard disk drive,especially music.
I believe you can take out the old hard disk,put it in an enclosure and connect up with a specific cable to his new MacBook,and extract what is required from the old hard disk.
Can anyone confirm on this?
Thanks.

Yes remove the drive but instead of getting a Drive Enclosure get a SATA to USB Adapter. Much more versatile and comes with a AC power adapter to make sure the drive is being properly powered up. Notebook size enclosures usually only use USB power to power the drive and that can be flaky on a Mac notebook.

Hard disk drive in CD-RW case

I received a seagate 20Gb hard disk drive from a friend which had been working in his PC which I hought I could connect in to my iMac in an old external cd writer casing. When I power it up though, the mac can't find the drive. Is this because the CD writer casing is not compatible with hard drives or is it possibly something else?
Cheers
Derek

Settings for master, slave, and cable select are changed by re-positioning the small plastic jumper(s) on the drive. Because the exact configuration of the jumpers varies from one brand to another, you should check the hard drive's manufacturer's web site for specific information.
An additional problem may concern the external case and the bridge chipset used in it. Was this a USB 1.1 CD-RW device? I once had an old Sony Spressa USB 1.1 CD-RW drive and installed a Zip drive in the case, after the CD-RW failed. Even with Iomega's Zip USB driver installed (with the Apple USB Support drivers), the Zip drive would choke when attempting to read anything but a small file on a disk. Attempts to write to a Zip disk, triggered a couple of error messages referring to missing (but necessary) "software." Essentially, the errors pertained to firmware in the ATAPI-to-USB bridge that didn't support the use of a "mass storage device," because it was programmed for an optical removable media device.

How does one SUCCESSFULLY transfer Time-Machine backup to a new (larger) hard disk drive using OSX 10.5.8

I have read a number of articles about how to transfer a complete Time-Machine backup to a new (larger) hard disk-drive. Some of these articles are specifically for OSX10.6 users, which are not applicable to me since I am operating with OSX 10.5.8.
However, I have tried several times to use the Disk Utility 'Restore' function, dragging my old time-machine volume into the 'Source:' box and my new volume into the 'Destination:' box. This works, of sorts, BUT the newly created volume on the new larger hard disk-drive remains the same size as the original volume on the old Time-Machine HDD, with no apparent way of increasing the new volume's size. So I am not really any better off:
E.g. the total capacity of my new HDD is stated by 'Disk Utility' to be 465.8 GB, of which I'm told 228.2 GB is used for the Backups.backdb folder, but only 4.6 GB of free space is actually available. Yet under the 'Partition' tab of 'Disk Utility' it tells me that there is still 236.4 GB of available space.
Does anyone know how to resolve this issue without upgrading to OSX 10.6?

First, how did you prepare your new drive? See:
Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
If you plan to partition this new drive then be sure you create a larger partition for TM than your old volume.
Next, clone your old TM volume:
Clone using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4.Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.

Upgrading Hard Disk Drive of Lenovo THINKPAD T500 2055 ?

Hi there,
My personal laptop is Lenovo THINKPAD T500 2055, and its main specifications as follows:
- Intel Core 2 Duo processor T9400 (2.53GHz 1066MHz 6MBL2).

- ATI Mobility Radeon 3650 with 256MB.
- 160 GB Hard Disk Drive, 7200rpm.
I really need to upgrade the Hard Disk Drive to a bigger size (500 GB, 7200 rpm). and, my major questions are as follows:
* Could you please advise me on which Hard Disk Drive (500 GB, 7200 rpm) should I buy for my T500 laptop?
For example, I found (http://www.amazon.com/gp/product/B003NSBF32) But I have no idea what T500 supports and what it doesn't... Therefore, I need your help to guide me about this matter. In other words, How do you know if ABC-Hard Disk Drive fits with T500 and XYZ-Hard Disk Drive doesnt fit? What is the clue in knowing what T500 accepts?
My another question is:
* How easy is it to remove/replace Hard Disk Drive in Lenovo ThinkPad T500 ???
I already watched CRU Removals/Replacements on (http://www.lenovoservicetraining.com/ion/R61_T61/index.html), But the clip is for ThinkPad R61 and T61. So, Could you please help me how to handle it with T500 ?
I would greatly appreciate your inputs.
Thanks for your consideration of my request, and I very much look forward to hearing from you soon !

SATA hard disk driver

hi
i got a SATA1 hard disk from toshiba model mk2555gsx and when i try to install any operating system it says it cant find any disk installed, my laptop is gateway model m-6804, i´ve donwloaded SATA drivers for my laptop ad it doest work, and i dont find hard disk driver from toshiba, please a dont know what else to do. thak you

First go into the bios and verify that the hard drive is recognized by the bios. If it isn't, then you either have a defective hard drive or a defective motherboard controller. According to the specs on that Gateway model it uses the same chipset that a lot of Toshiba Laptops use so it should support that hard drive. Please note that while Vista and Windows 7 have built in support for SATA hard drives, XP and Windows 2000 do not and will require integrating the SATA drivers into the XP install disk. ME, 98, and all previous versions of Windows do NOT have ANY support for SATA and will NOT work with SATA period.
Next, Toshiba's Hard Drive Support is located at http://sdd.toshiba.com/main.aspx?Path=ServicesSupport/TechnicalSupport This forum is ONLY for Toshiba Laptops and Projectors.

DV9925nr - How to Backup Hard Disk Drive After S.M.A.R.T. Drive Failure Message

I purchased a DV9925nr laptop from Bestbuy about 13 months ago. Six months ago it started having the sporadic and randomly abrubt shutdown problem that so many others seem to be having.
Two days ago it developed a new problem:
I left my laptop on for a few minutes and when I returned, it was to a black screen with this message: "SMART Drive failure predicted on Hard Disk 4. WDC WD2500BEVS - 60UST0-(S1); warning: Immediately backup your data and replace your hard disk drive. A failure may be imminent. Press F1 to continue."
My question:
We have a network with two laptops and a desktop computer. There is plenty of hard drive space on the desktop system. My father has the same exact laptop model as mine. Can I put my hard disk drive into his second disk drive bay so that I can backup my files over the network to my desktop system? How would the laptop know which hard drive to boot from since they both have the same operating system on them (I am not familiar with SATA drives)?
I hope I didn't buy a lemon. Any help would be greatly appreciated.

Are you trying to do this while booted from the OS or from the install Disk? If your booted into the OS then the repair option shouldn't be click-able. Beyond that, there might be some 3rd party software that could force a reformat and/or erase. I did try to find you something but didn't come across anything specific to what your trying to do. You probably already know this, but the purpose of S.M.A.R.T. is it acts as an early warning indicator. This means the drive is no longer dependable and may fail without warning in the near future, resulting in losing all data. With that being said, I've used a hard drive that S.M.A.R.T. indicated was failing for 3+ years without a hick-up. I don't use it for anything imported though. When I have more time and if I come across anything that might get the job down, I will add to this posting. The worst case scenario is that there is no way to reformat and/or erase the drive due to the state it's in. At that point, the only thing left to do is recycling the drive.

Comparison of SSD with hard disk drives

Attribute or characteristic
Solid-state drive
Hard disk drive
Spin-up time
Instantaneous.
May take several seconds. With a large number of drives, spin-up may need to be staggered to limit total power drawn.
Random access time[45]
About 0.1 ms - many times faster than HDDs because data is accessed directly from the flash memory
Ranges from 5–10 ms due to the need to move the heads and wait for the data to rotate under the read/write head
Read latency time[46]
Generally low because the data can be read directly from any location; In applications where hard disk seeks are the limiting factor, this results in faster boot and application launch times (see Amdahl's law).[47]
Generally high since the mechanical components require additional time to get aligned
Consistent read performance[48]
Read performance does not change based on where data is stored on an SSD
If data is written in a fragmented way, reading back the data will have varying response times
Defragmentation
SSDs do not benefit from defragmentation because there is little benefit to reading data sequentially and any defragmentation process adds additional writes on the NAND flash that already have a limited cycle life.[49][50]
HDDs may require defragmentation after continued operations or erasing and writing data, especially involving large files or where the disk space becomes low. [51]
Acoustic levels
SSDs have no moving parts and make no sound
HDDs have moving parts (heads, spindle motor) and have varying levels of sound depending upon model
Mechanical reliability
A lack of moving parts virtually eliminates mechanical breakdowns
HDDs have many moving parts that are all subject to failure over time
Susceptibility toenvironmental factors[47][52][53]
No flying heads or rotating platters to fail as a result of shock, altitude, or vibration
The flying heads and rotating platters are generally susceptible to shock, altitude, and vibration
Magneticsusceptibility[citation needed]
No impact on flash memory
Magnets or magnetic surges can alter data on the media
Weight and size[52]
The weight of flash memory and the circuit board material are very light compared to HDDs
Higher performing HDDs require heavier components than laptop HDDs that are light, but not as light as SSDs
Parallel operation[citation needed]
Some flash controllers can have multiple flash chips reading and writing different data simultaneously
HDDs have multiple heads (one per platter) but they are connected, and share one positioning motor.
Write longevity
Solid state drives that use flash memory have a limited number of writes over the life of the drive.[54][55][56][57] SSDs based on DRAM do not have a limited number of writes.
Magnetic media do not have a limited number of writes.
Software encryption limitations
NAND flash memory cannot be overwritten, but has to be rewritten to previously erased blocks. If a software encryption program encrypts data already on the SSD, the overwritten data is still unsecured, unencrypted, and accessible (drive-based hardware encryption does not have this problem). Also data cannot be securely erased by overwriting the original file without special "Secure Erase" procedures built into the drive.[58]
HDDs can overwrite data directly on the drive in any particular sector.
Cost
As of October 2010, NAND flash SSDs cost about (US)$1.40–2.00 per GB
As of October 2010, HDDs cost about (US)$0.10/GB for 3.5 in and $0.20/GB for 2.5 in drives
Storage capacity
As of October 2010, SSDs come in different sizes up to 2TB but are typically 512GB or less[59]
As of October 2010, HDDs are typically 2-3TB or less
Read/write performance symmetry
Less expensive SSDs typically have write speeds significantly lower than their read speeds. Higher performing SSDs and those from particular manufacturers have a balanced read and write speed.[citation needed]
HDDs generally have symmetrical read and write speeds
Free block availability andTRIM
SSD write performance is significantly impacted by the availability of free, programmable blocks. Previously written data blocks that are no longer in use can be reclaimed by TRIM; however, even with TRIM, fewer free, programmable blocks translates into reduced performance.[25][60][61]
HDDs are not affected by free blocks or the operation (or lack) of the TRIM command
Power consumption
High performance flash-based SSDs generally require 1/2 to 1/3 the power of HDDs; High performance DRAM SSDs generally require as much power as HDDs and consume power when the rest of the system is shut down.[62][63]
High performance HDDs generally require between 12-18 watts; drives designed for notebook computers are typically 2 watts.

I wish I could get my head round the SSD vs HDD with a NLE rig. My builder is trying to persuade me to use a Toshiba 256Gb THNSNC256GBSJ for OS and programs, and it is only NZ$20 more expensive than the 450Gb 10k rpm VelociRaptor I was originally planing to use for the OS. That sounds suspiciously cheap to me, and I am concerned about the finite writes to SSD - mainly because I don't really understand it.
The rest of the new build is
3930K
Gigabyte X79-UD5
8 x DDR3 1600
Coolermaster with 750W PSU
Geforce GTX570
I plan to transfer the drives from my current system as a starting point, and reassess after giving it some use. That means
Either the above SSD or 450Gb 10k Raptor for OS (new drives)
300Gb 10k rpm Raptor (currently used for OS in old box)
150Gb 7k4 rpm Raptor (reserved for Photoshop Scratch in old box)
2 x 1Tb WD Blacks (data drives)
2 x 1Tb WD USB3 externals
I don't know how I would configure the drives in the new box, but have seen Harm's table and will try to follow his advice. It's a dreadful thing to admit, but I don't have a backup strategy, and the above drives are well over half full. Well over! And I am only just getting serious about video, (the rest is mainly CR2 files from my Canon 1Ds3 and 1D4)
I know it must be like banging your head against the wall, but should I avoid that SSD and go with the 450G Raptor? I have read a comment that the WD Blacks don't work well as Raid0. Is that BS or true?
I am about to give the go-ahead so need to confirm the spec.

Just bought a Lenovo 3000 N200 without a hard disk drive, need software

I just bought a Lenovo 3000 N200 Type 0769-BLG assembly date 07/09 from e-bay, it looks brand new but it had a fault, it was dead, perhaps a faulty motherboard and the hard disk drive had been removed. Assuming I can get the fault fixed, where can I get the Lenovo software that came with the original hard disk drive, I would prefer a free source, if that is possible, perhaps some kind person has put all of the CD's on to a DVD that I can borrow or buy a copy of. I was an IBM employee for 30 years before retiring 15 years ago. Dan McLean in Scotland, UK.
