Added 2nd Hard Drive - Which Format Do I Select?

I just added a 2nd hard drive. It shows up in disk utility. I know I must format it before I can use it. But, there are 6 choices in the Volume format drop down: Mac OS Extended (Journaled), Mac OS Extended , Mac OS Extended case - sensitive journaled, Mac OS Extended case - sensitive, MS-DOS file system, UNIX File System. Is there some information on the Apple site that explains these 6 formats?
G5 2.3 dual   Mac OS X (10.4.6)   Which is best to use?
G5 2.3 dual   Mac OS X (10.4.6)  
G5 2.3 dual   Mac OS X (10.4.6)  

Actually, when I have had a drive with problems like bad blocks, I find Intech Speedtool ZoneBench to show up problems the best. It also includes ability with another part of the suite to map out bad blocks (never found any) but I did have to do a 7-way erase with one drive that kept having problems.
An entire 4GB area went from normal 56MB/sec down to 31-33MB/sec - either partition off that area, or just realize it has this problem with longer seeks (the time to go from inline to spare sector - some SCSI drives locate spares on the same track to reduce seeks.
ZoneBench can be set to a 511MB test file, and can test 60? areas per volume, so you can force read/write to over 33%.
The most important areas of a drive that cannot have any bad blocks are the areas that are not part of user allocated space, partition tables, directory (maybe) and the area of the journal file.
If it solved a problem 1% of the time or less, would vendors include it in their "how to setup a drive for end users"?

  • Need help adding 2nd hard drive

     Hey guys whats up. I need some advice about adding a second hard drive. Right now i have a WD 320GB 7200 RPM IDE Ultra ATA100 Hard Drive running on the primary IDE. Everything is fine but i wanted to get a smaller and faster drive for the operating system and for some small video editing. I recently purchaced a Western Digital Raptor 36.7GB 10,000 RPM Serial ATA150 Hard Drive.
    Now the questions:
     1. How should i assing the drives? (which master/slave/cable select)
     2. Also am i going to have to do anything since im going to have one on the IDE and another on SATA?
     3. Any advice that you have...
     What i was thinking is this...i should disconect my current HD and hook up the new one to SATA port 2, and set it to master(or CS maybe). Format it and then install the operating system. Once OS installed and working, ill hook back up the IDE drive and make the setting to slave(or CS maybe). Then uninstall the operating system from the IDE.
    Thanks for any input

    Thanks NovJoe,
     What setting (master/slave/cable select) should i set the IDE drive to? And yes i do want my OS on the raptor.
    Thanks for your advice...didnt think that anyone was going to.

  • Adding 2nd hard drive

    I have a Power Mac G5 dual 2ghz with 1-160 gb hard drive.
    Want to hook up a second drive.
    What are the positives and negatives to adding an
    external drive or an internal drive?
    Any suggestions would be greatly appreciated.

    I agree with Ben. If you just need more storage, internal is the way to go -- faster access, more convenient.
    If you're using the new drive as a backup, external is better because whatever fries your computer (necessitating a restore from backup) would most likely damage internal drives far faster than an external backup which you can unplug and disconnect between backups.
    So, what are you planning to use it for?
    Hope we helped. If we did, please award points!

  • Problems Adding 2nd Hard Drive

    Bought a new Western Digital WD10EARS 1 TB hard drive to add into drive bay "B" in my G5. I have two problems:
    1) Unfortunately the drive has no mounting "buttons" (screw-mounted hemispherical plastic buttons) that screw into the sides of the drive. These are needed to retain the drive in the molded plastic drive holder in the Mac. I need to source four of these buttons before I can install the drive.
    2) Also unfortunately, the new drive does not have a 4-pin Molex-type power input connector like the one on my OEM WD2500 hard drive in drive bay "A." In fact I see no power connector at all. There are two small connectors on the left side of the rear panel of both drives that look identical, and Apple has supplied extra matching connectors which will work with the new drive, and there is also a spare power plug of the Molex type in the Apple wire harness, but since there is no corresponding connector on the new drive, I am out of luck there. Unless, somehow, power would be fed to the new drive on one of the left side connectors that do match...
    Would appreciate any useful advice, thanks!
    ---- Bill Strohm

    Thanks to both BDAqua and Old Comm for your responses. I will check for those 4 spare "overmold" mounting buttons after sending this reply. They should be there; never touched them previously. That will take care of problem #1.
    Now for problem #2:
    "Yes, SATA Power is not shaped like Molex. They are likely there already, both SATA Power & SATA Data, just hidden beside/behind the other drive or mountings. There are Molex->SATA power adapters though."
    Not sure what this means. As I wrote above, Apple has provided a spare Molex power connector on the same wire harness as used by the OEM drive, but there is no connector to plug it into on the new drive. Apple has also provided a spare set of two connectors, identical to the two connectors on the left side of the OEM drive, which look to match the two connectors on the left side of the new drive. Is one of those two connectors the "SATA" power connector? Or are you saying there is a third "SATA" power connector hiding somewhere in the computer chassis that I cannot see? Trouble is, I don't know what a "SATA power connector" looks like. The only unused connector on the new drive is over on the right side of the rear, on the drive's PC card itself, recessed way back behind a cutout in the right side of the panel, i.e. the panel doesn't run all the way across the rear of the drive; it stops short, leaving an opening through which I can see the top of the PC card which has a very small four-pin connector attached. Is that the SATA power connector? Seems very small to be for power... ??

  • [Solved] Strange free space after adding 2nd hard drive

    Hello,
    Im pretty new to linux but am learning pretty fast, fast enough that I needed to install a second hard drive.
    Every thing went well, got the new drive in and mounted to /home and moved all my old /home to the new drive. After all that I went to delete the old /home on hda resize the / partition to use the rest of the drive.
    I used gParted 0.5.0 and booted from their live CD and did the deed. BUT now drive hda (40GB drive) shows that / is taking 36.92GB, when it was originally using about 4GB on the original 7GB / partition.
    I ran the disk usage tool and..well
    1) It shoes that I'm using 4GB of 40GB
    2) Only shows that I have 44GB available when I have 2 40GB Drives installed.
    can someone tell me whats going on here?
    to recap
    Originally the 1 drive was laid out as
    /boot - 100MB
    swap - 260MB
    /       - ~7GB
    /home - remainder of drive
    then I (wanted to) changed it to
    [sda]
    /boot - 100MB
    SWAP - 260MB
    /        - Remainder of drive
    [sdb]
    /home - 40GB
    Thank you for any help.

  • Permissions problem after adding 2nd hard drive and putting user home there

    I added a 2nd drive and put my user home on this. The reset password tip from command line at startup never sees this new volume, so I have been having to add my user to most files manually.

  • Dv7 3085dx won't power on after adding 2nd hard drive

    I'm attempting to add a 2nd drive to my laptop (dv7 3085dx). The drive is a Seagate Momentus 750GB drive (ST9750420AS). I purchased the drive caddy and connector from Newmodeus. The laptop will not power on after the drive is installed in the 2nd bay. Everything is fine if the drive is disconneted.
    Any ideas?

    Are you absolutely sure you got the right caddy and cable from newmodeus? They sell several different ones for the dv7 series and they look similar but are not compatible with each other. I understand the reluctance to try hot-plugging it.

  • Adding 2nd hard drive(IDE 40gig)  to B&W G3 w/ 9gig SCSI drive

    Recently got a 450 B&W G3 with a 9gig SCSI ultra something drive in it already and i would like to add a 40gig IDE drive as a second. the scsi drive is hooked through a scsi card and is the main drive. i want to just add the second drive for more storage. when i plug up the drive and start up, it does not see the drive. I know i'm missing something little to get this to work, but I don't know alot of the techincal terms and meanings to ask the right questions. any help or if someone can direct me to an older article that might help would be great!!! Thanks!!

    Hi, Papa -
    Welcome to Apple's Discussions.
    Make sure the drive is jumpered correctly. There is a block of exposed pins at the same end of the drive where the power cable and data cable are attached. On those exposed pins will be one or more little plastic-looking things bridging pin pairs - these are the jumpers.
    There should be a label affixed to the drive in the vicinity of the jumper pin block; this label depicts the various configurations of where jumpers should be placed for various settings.
    For your model Mac, you should use the jumper setting for "Master". Exception - if the drive is a Western Digital brand, it may have a setting named "Single" - if so, you should use that when the drive is the only device on the bus.
    If you have not yet initialized (formatted) the drive, do so. Most drives are not usable until they have been prepared for a Mac by initializing the drive; initializing a drive places Mac drivers on it, and structures the platter for use by the OS.
    You can use OSX's Disk Utility to initialize the drive. There should be sufficient info in OSX's Help section to use Disk Utility to do that. Some items of note -
    • If you want that drive to be accessible when the machine is booted to OS 9 at some time, be sure to select the option to install OS 9 drivers.
    • Select "Mac OS Extended" as the format for the drive.

    When i added my 2nd HDD I was ready to get it ordered and shipped, so it would arrive before I arrived home. I also was not sure if it would be offered anywhere else and be 100% compatible. The quality of the factory HP part is good. Since then I found a cheeper source. Newmodeus DV7-3xxx Hard Drive Caddy $27.95 +tax +shipping. Not sure if the quality is the same.

  • 2nd hard drive for HP Pavilion dv7t-4000 CTO Notebook - What do I need?

    Hi, I have the HP Pavilion dv7t-4000 CTO Select Edition Entertainment Notebook (Product # WV703AV). It has room for two harddrives but only came with one. What would I need in order to install the second hard drive? Would I need just a connecting cable or do I also need caddy or kit?
    Also, could I get a solid state? Would my notebook support that or does it only use regular ones?
    Currently, I'm running Windows 7 64bit. I've got a 500GB hd (which came partitioned with hp tools/recovery).
    Any help with what I would need for a traditional hdd or ssd would be greatly appreciated. I tried to look through other people's posts first,  but couldn't find anything specific to my model. Thanks for your time!
    This question was solved.

    Hi:
    The only place I know of where you can get a 2nd hard drive kit is from this vendor.
    http://www.newmodeus.com/shop/index.php?main_page=product_info&products_id=345
    Your notebook should be able to work with a SSD but I cannot guarantee it.
    I really don't see any point in adding a SSD unless you make it the primary hard drive, and in order to do that, you would need to get a SSD the same size as the original 500 GB hard drive to use the recovery disks to reinstall the operating system.
    Most folks get smaller SSD's and they use the W7 product key to activate a plain installation of W7.
    If you can read all 25 characters of your windows 7 product key you can make your own installation media and use that to install Windows on a smaller than 500 GB SSD.
    If you can read the 25 character Microsoft windows 7 product key, you can download plain Windows 7 ISO files to burn to a DVD for the version of windows that came installed on your PC, and that is listed on the Microsoft COA sticker on your PC's case.
    Burn the ISO using the Burn ISO option on your DVD burning program and burn at the slowest possible speed your program will allow. This will create a bootable DVD.
    Or use the Windows 7 USB/DVD installation tool to compile the ISO file you download from Digital River. Link  below. You need a 4 GB flash drive to use the USB method of compilation.
    http://download.cnet.com/Windows-7-USB-DVD-Download-Tool/3000-18513_4-10972600.html
    Use the 25 character product key on the PC to activate the installation.
    The key will activate either a 32 or 64 bit installation.
    Then go to the PC's support and driver page to install the drivers you need.
    Link to the W7 ISO file downloads is below.

  • Looking for a 2nd hard drive on DV9700

    I want to add a 2nd hard drive to my HP dv9728ca. Are there any specs I should look for? Right now I have a 160GB hd, and the manual ( http://h10032.www1.hp.com/ctg/Manual/c01295898.pdf ) seems to indicate my only choices are 120GB or 160GB. According to the service manual, if I want a 200GB or 250GB, I can't use my 160GB anymore. The possible options are as follows : 250x2 (5400), 200x2 (4200), 160x2 (5400), 160+120 (5400), 120x2 (5400 or 7200, but both the same). Now I've upgraded computers before, even built some from scratch, and I've never seen this type of requirement. Is this for real? I've read a post from someone saying he had trouble with his new drive which was bigger than his original one. What about the 1.5GB/sec vs 3.0GB/sec? My understanding is that the 3.0 is downward compatible, but some seem to pretend you have to set a jumper on the drive to bring it down to 1.5. Any help would be appreciated. And what if I add a 7200rpm drive instead of 5400rpm? I don't see how these should cause any trouble, but from looking around it seems HP motherboards are very specific as to what they'll let you do. I already purchased the caddy kit, all I need is the hard drive, but I don't want to end up with one that's not compatible.
    If anyone's added an additional hard drive to a dv9700 series laptop, please let me know what model you chose (brand, capacity vs what you had, 5400/7200, 8MB/16MB).

    Hi, I have dv9730ca laptop myself and I have 2 160GB seagate 5400rpm 8MB hdd's, they have an external data transfer rate of 300MB/sec and an internal data transfer rate of 1.1GB/sec. They do get up to around 55oC (i use cpuid - hwmonitor to check this out) and I have heard using the 7200rpm hdd's can increase the heat output so I would recommend using the 5400rpm hdd's instead. The best way I have found to get over the heat issue from any laptop is to use a targus chillmat, it has 2 fans and runs off a usb port. I hope this info helps you out

  • Set Bios to Boot from 2nd Hard Drive

    Hello HP forum!
    I have a situation that I am afraid may be hardware related, so this is my last attempt for help before I let it go.
    In this laptop, I have two hard drive slots with two hard drives. The second hard drive was used as an HP backup/restore drive as shipped from the factory.
    I would like to format and install an OS onto the 2nd drive for easy-peesy dual booting. (This is a work computer, so easy + time-efficient + low-risk is optimal). I have actually done this already, but the BIOS does not seem to detect two bootable hard drives. In the BIOS (pretty sure not EFI) boot list, it simply shows the option to boot from "Notebook Hard Drive", which boots from the 1st drive.
    In my 1st Drive's Windows 7, I can read the contents of the 2nd disk, so it is definitely functional. Also, replacing the 1st drive with the 2nd drive, I can successfully boot from it, so it is bootable. This seems to imply that my hardware understands that there are two drives, but the BIOS does not recognize that port to be a bootable option, but only a storage option... I guess?
    My question is, then, how can I set up my computer to give me the option to boot from either drive? Is it even possible on this hardware?
    Thanks
    Rex

    Did you make sure to update your bios as that could be something that might require a bios update? Also if you can't see or locate that second drive in the BIOS you might not have the option to boot from the second drive? Does the bios also give you the option to boot from the cd drive? Your asking us to see a boot bios screen and unless some has your same make/model no everyone will be able to confirm or see what your asking so unless you can do more looking at all your bios options you might not have the option to boot from the second drive port.

  • How to install Solaris 10 with Win XP on 2nd Hard Drive

    hi everyone,
    I'm totally new to Solaris. As an enthusiast, I wants to install Solaris 10 on my Win XP PC's 2nd Hard Drive(40GB, empty) from Solaris 10 DVD.
    I need help from how to format 2nd Hard Drive to how can I configure the PC so it asks me which OS to load every time.
    I will highly appreciate everyone's help as I've just joined SDN. Many Thanx in advance, Jags

    Happened upon this post while searching for an answer to something else and figured I would give my 2 cents on what you are trying to do so as to offer you some other ideas, as in stuff I have done personally in similar situations, just in case the other suggestions don't work out (and to avoid repartitioning your main hdd if it is your ONLY computer with an OS you have available).
    Assuming you have a standard tower or mid-tower with at least 1 free 5 1/4" bay open, and if your motherboard doesn't support booting from a slave drive, and if you prefer a hardware solution so your OS installs are isolated from each other to be certain no corruption happens, like I personally do*. Then you may consider a pair of key lock internal hard drive racks (newegg search "hard drive rack ide" or sata). You would need at least 1 free 5 1/4" bay for the rack mount, then place the hard drives in their housings, each set as master, and you can stick in which ever OS drive you want, turn the key, then boot up (I recommend storing drives not in use in some large anti-static bags for protection). If you have 2 open slots, like I did on my tower, then you can connect both to the same cable and leave both in at all times. Just make sure ONLY 1 drive is keyed "on" at a time, or else you will get errors due to duplicate masters set. Also make sure you ONLY turn the keys when the system is OFF, the racks do NOT make the drives hot-swappable, it is only to offer an easier solution for using multiple hard drives on one PC so you don't have to open the case all the time and potentially damage the pins or the drives when switching them out.. Also you may need longer cables depending on the motherboard controller placement and the size of your tower, 80 wire 40pin if you are dealing with IDE (when you get longer I've noticed less 80 wire and more slower 40 wire cables). As always when dealing with the actual hardware, be extra careful, make sure power is off and PC is unplugged, touch the PC power supply if you don't have better solutions such as anti-static mat/wrist band, etc. You probably know all of this, but just making sure.
    *I lost a lot of data one of the first times I tried an open source OS many years ago (some Linux distro, I forget which), I tried to repartition my windows 98 drive, it worked fine for about a week booting between the two, then most my personal windows files suddenly were random sizes and random folders ended up full of garbage files with garbage file names among other peculiar things.. If I partition a drive I generally only do it BEFORE I put data on it or install OS's.. or at least make CERTAIN that I have adequate methods for restoring my OS and personal files (such as imaging my OS install to a larger drive temporarily, etc)..
    Anyway, was just offering some possible alternatives to repartitioning your main OS drive.. -TCP

    I bought a new external hard drive for backups, but time machine won't do a full back up. 
    I think it is remembering backing up onto previous external hard drives, which I don't own anymore.  How do I do a new full backup?
    When I bought the new (used) iMac, I also bought an external hard drive for backups.  It worked fine, but my husband stole it.
    Then I bought a new external hard drive (Seagate) and it worked fine for three weeks, then died.
    So I just got a new external hard drive, which was put together from an internal hard drive and a hard drive enclosure. 
    Time machine did the first backup today, and it should have taken 9 hours like it did on the previous first time full back up.  Instead, it took 30 minutes.  That can't be right.  I want to start over and do a full backup to make sure everything gets onto my new external hard drive, but I can't figure out how to do that.  Please help.
