Windows XP won't install on a Bootcamp partition Following replacement program of 1TB Seagate Hard Drive

Following 1TB Seagate hard drive replacement on a late 2009 machine running Mac OS X 10.6.8, bootcamp would not install windows XP on a disk partition. Now that this is upgraded from OS X 10.6.8 to Mavericks, is it possible to install windows XP on a bootcamp partition?

Make sure your "Function Key" lock is on. Mine did the same thing. I Have a new Microsoft multimedia keyboard and F8 would not work until I hit the "Function Key" lock on the keyboard.
Good Luck

My Hybrid 1TB Seagate Hard Drive will not work in my data doubler caddy installed in the optical bay of my MacBook Pro

Thanks for all the advice. It looks like I have finally got my MBP working again (after two weeks of pain).
The WD HD works fine internally, but restoring from TM introduced a whole load more of issues/incompatabilities (see above). Eventually the only thing left was to re-build rather than restore:
i) mount the WD disk internally and install Snow Lepoard from the orginial installation disks
ii) get online, and after much trying download Lion (previously purchased). Perfrom all update.
iii) Connect my Time Capsule, identify my data, photo and music files and then copy them accross by hand
iv) install all the other applications (e.g. MS Office:mac, etc) from scratch.
This exercise has shown me that even though tools and procedures exist to address separate issues, when the complexity of inter-dependence is introduced there are a raft of problems that crop up.
Now I am back in business I will be using TM and CCC to take full and regular copies. I did this previously, which has saved me from losing my data and cherished pictures, but hopefully next time (and I'm sure there will be a next time) the recovery will be less infuriating.
BTW I got a refund on the Seagate Momentus XT. They guy in the shop said it wasn't the first time he'd heard of this issue with MBPs. Great.

After performing a clean install, is my startup disk correct for apple stock 1TB fusion hard drive? I think I may have to reformat.

After performing a clean install on a stock apple 1TB fusion Hard Drive it appears as things got reversed and showing my startup as not using the SSD portion. The SSD portion of the fusion drive used to be on top in disk utility, now its on the bottom. It also appears that I have to many partitions. Im thinking i need to reformat my Hard Drive again. I can't seem to find any answers.

Hi,
According to your descriptioin, I don't think this is system problem, it should be Intel driver problem. It would be contact Intel to confirm this issue whether this is their driver problem.

I running snow leopard on my MBP- where can I find the drivers for windows XP if I install them via bootcamp? Thanks!

You won't find them until you are in Windows.
Helps to read even print the guide.
If you have auto run enabled, which is a security risk, the Apple setup.exe will run.
Otherwise, just run that.
Either use your OS X DVD, or use the drivers downloaded by Boot Camp Assistant.
Two different ways to get them.

Windows updates won't install

Hello,
I have a remote user whose Windows updates won't install. He has a Dell laptop with Windows 7 Pro 32-bit. You can bring up the update windows and start the install but, at exactly 10 seconds, it just says "Updates failed" and doesn't really give
any more information.
I saw the Windows update service was stopped, I started it and that didn't seem to help. I also tried the update troubleshooter and that didn't do anything. I checked for malware and didn't find any, and he has plenty of disk space. I didn't see
anything in Even Viewer or Reliability Monitor either.
What could it be?
Thanks.
Chris Hansen

Hi Chris,
Firstly, please check if those Windows Update have already installed:
1. Open Windows Update by clicking the Start button. In the search box, type
Update, and then, in the list of results, click Windows Update.
2.In the left pane, click View update history.
3. Click Installed Updates at the top of the page, there check if any Windows Update installed recently.
If there is no any Windows Update installed, try to
reset the Windows Update component to check if it could resolve the issue.

Windows Updates won't install - Error 0x80072EFD

Question
Windows Updates won’t install. I’m receiving Error 0x80072EFD. What can I do to solve this?
Answer
This particular error means that your computer was not able to connect to the Internet when it tried to install updates. First, check your Internet connection and then try again. If that doesn’t work, try the methods below.
Method A: Make sure that Windows Firewall is turned on, and temporarily disable third-party firewalls
Warning This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
To complete this method, follow these steps.
Step 1: Make sure that Windows Firewall is turned on
To open Windows Firewall, click the Start button, and then click Control Panel. In the search box, type firewall, and then click Windows Firewall.
Click Turn Windows Firewall on or off.
Click On (recommended), and then click OK.
Step 2: Temporarily disable third-party firewalls
Click the Start button, click Control Panel, and then, under System and Security, click Review your computer's status.
Click the arrow button next to Security to expand the section.
Under Firewall, read the firewall status note. This information will indicate which, if any, firewall is installed and whether the firewall is turned on. For example, for ZoneAlarm, the notice will say ZoneAlarm Firewall is currently ON.
Open the third-party firewall application that is listed in the firewall status note, and temporarily disable the firewall. If necessary, refer to the firewall application documentation, or contact the application vendor for more information about how to temporarily disable the application.
Step 3: Try to install the updates again
If this method resolved your issue, follow the steps in Method B, step 2 to re-enable your third-party firewall. You might want to also check for and install any necessary updates to your third-party firewall.
If this method did not resolve your issue, continue with Method B.
Method B: Temporarily disable third-party antivirus software
Warning This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
Note If your third-party firewall is still disabled from Method A, do not open e-mail messages, surf the Web, or use instant messenger at this point.
Step 1: Locate and temporarily disable your third-party antivirus software
Note Windows does not detect all antivirus software, and some antivirus software doesn't report its status to Windows. If your antivirus software is not displayed in Windows Security Center, and you're not sure how to find it, try any of the following:
Look for the antivirus software in the list of programs on the Start menu.
Type the name of the software or the publisher in the Search box on the Start menu.
Look for the software in Action Center:
Click the Start button, click Control Panel, and then, under System and Security, click Review your computer's status.
Click the arrow button next to Security to expand the section.
If Windows can detect your antivirus software, it will be listed under Virus protection.
If the software is turned on, check the Help documentation that was included with the software for information about how to disable it.
Note You may have to look in the application documentation to determine how to do this.
Step 2: Check for Windows Updates
As soon as the antivirus software is temporarily disabled, visit the Windows Update or Microsoft Update site again, and try to download and install updates.
If this method resolved your issue, and you were able to install the updates successfully, you should re-enable your third-party antivirus software.
If this method did not resolve your issue, continue with Method C.
Method C: Disable software accelerator programs
Disable any software accelerator programs that may be running. Some examples of these programs are file download accelerators and Internet speed accelerators.
Note If your third-party firewall is still disabled from Method B, do not open e-mail messages, surf the Web, or use instant messenger at this point.
Step 1: Disable software accelerator programs
To do this, select from the following options:
See the documentation that was included with the program.
View the Help files for your program.
Contact the program vendor. For information about how to contact the program vendor, visit the following Microsoft Web site:
http://support.microsoft.com/gp/vendors
Step 2: Install Updates
As soon as the software accelerator program is disabled, visit the Windows Update or Microsoft Update site again, and try to download and install updates.
If this method resolved your issue, you should enable the software accelerator programs that you disabled in Step 1.
If this method did not resolve your issue, continue with Method E.
Method D: Add the Windows Update Web site and the Microsoft Update Web site to the Trusted Sites list
Note If your third-party firewall is still disabled from Method A, do not open e-mail messages, surf the Web, or use instant messenger at this point.
To add the Windows Update Web site and the Microsoft Update Web site to the Trusted Sites list, follow these steps:
Start Windows Internet Explorer.
On the Tools menu, click Internet Options.
Note If you are using Internet Explorer 7, and the menu is not available, press the ALT key on your keyboard to access the Internet Explorer Menu.
Click the Security tab, and then click Trusted Sites.
Click Sites, and then click to clear the Require server verification (https for all sites in this zone check box.
In the Add this Web site to the zone box, type the following addresses, and then click Add after you type each address:
http://update.microsoft.com
http://windowsupdate.microsoft.com
Click OK two times.
Try to install the updates again.
If this method resolved your issue and you were able to install updates successfully, you should re-enable your third-party firewall if it is still disabled. To do this, see step 2 in Method A.
For more methods and advanced troubleshooting techniques, see You may encounter temporary connection-related errors when you use Windows Update or Microsoft Update to install updates.

Mark, I've just been through this update issue with two installations. In my case, it seemed intertwined with authentification and indexing not working, either. Upon a transfer of my system disk to new hardware I got hit with the issue and couldn't fix it. Which is why I did a clean install of Win7 ultimate 64bit on my T61p. The install (including update) worked great until I ran the intel matrix storage manager update. This broke windows update. If you surf the web, and include "intel rapid storage manager" or "intel matrix storage manager" and "Windows update fails", you'll see that a lot of folks feel that the intel driver (or how windows handles it) is what breaks update. I tracked this down to a driver, iastor.sys, in windows\system32\drivers. I was able to fix my Window Update by copying an iastor.sys from another recently built machine (should be exactly the same, but this was my wife's T510, but still Win 7 Pro 64) to overwrite the iastor.sys that the intel update changed. To be clear: I couldn't get windows update or indexing to work. I overwrote* the "bad" iastor.sys with one that worked on another computer. Rebooted. Update worked. I just wanted to point out that instead of blindly installing updates to fix problems, folks should be aware that sometimes the update is the problem. Especially as these systems are off warranty and the drivers are not being updated. I've asked elsewhere, so let me ask here: Where is the System Interface Driver for t61p? Not listed anywhere on site, links on the web referring to it are all broken. Is the System Interface Driver now part of another driver program? Thanks!

You did something wrong. Why was your usb hard drive connected? Did you somehow format the external hard drive? If so, your files are gone.

Seagate Hard Drives not detected by the Windows 7 installer

I've spent hours on this trying every conceivable reason, so I apologize in advance for the length on this post.
I connected a Seagate 320GB 7200.10 hard drive to a P35 chipset system and attempted to install Windows 7 RTM onto it. The installer got to the part of detecting hard drives, but could not detect this drive. Native SATA mode was enabled, and AHCI was enabled.
I disabled Native SATA mode, then after that failed I also tried disabling AHCI by setting the controller to IDE mode. Still, the Windows 7 installer refused to detect the drive.
I replaced both the SATA & power cables, verified the drives are detected by the AHCI firmware and the BIOS, and I even tried different motherboard SATA ports to no effect. I took a second , identical Seagate 320GB SATA hard drive, this time pre-formatted it inside Windows 7 RC using NTFS defaults, and again (with and without AHCI and Native SATA mode) Windows 7 will not see this hard drive either!
I even downloaded the AHCI preinstall drivers and loaded these using a flash drive. When I did Windows 7 would autodetect the ICH9 driver and I would click Next. Windows 7 would suddenly see the drive, but all options to format or create a partition are grayed out. Clicking the more info button gives me this error message:
"Windows cannot be installed to this disk. This computer hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu."
I used the AHCI preinstall drivers specific for the motherboard (Vista 64) and I also tried the AHCI preinstall drivers from Intel for Windows 7 RC 64. As of this writing Intel has not released official Windows 7 RTM Intel Matrix Storage Manager drivers.
In frustration I installed a SSD (with AHCI and Native SATA mode enabled) and suddenly Windows 7 detects the SSD without needing to load any driver (as would be expected, since Vista and 7 include Intel Storage Manager drivers by default already). I installed Windows 7 RTM 64bit onto the SSD without issue.
15 minutes later I was at the Windows 7 desktop, and Windows 7 was showing the Seagate 320GB hard drive under "My Computer" as normal. I could even use the Seagate hard drive as normal as if nothing was wrong. For kicks I launched the Windows 7 installer inside Windows 7, but as you can see below it still refused to see the drive, despite the drive being shown under My Computer:
(Since I can't use thumbnails, here's the direct link: http://i111.photobucket.com/albums/n129/Chanur64/Box/Howpossible.jpg )
Also I should note I previously had Windows 7 Beta installed on an IDE drive in this exact system, and had no problems with it. Windows 7 RTM would allow me to install to an IDE drive and allowed me to install to an SSD, but it cannot see and cannot install onto both Seagate 320GB hard drives. These Seagates are known good drives previously part of a RAID 5 array.
If anyone knows what is going on or has some ideas I've not tried I would love to hear from you and get this figured out. Suffice to say this is not a promising start for Windows 7.

I just had to solve the same issue with a Seagate Momentus Thin hard drive (
http://www.seagate.com/www/en-us/products/laptops/slim-laptop-hard-drives/)
Tried several BIOS configuration, AHCI drivers, etc and Windows 7 32bits couldn't detect the drive.
My solution was to boot with a USB pendrive with HirenCD tools (http://www.hiren.info/) and use a partition manager to erase disk contents, create and format a partition.
Windows 7 detected the hard drive for the first time and now is installing, so.. crossing fingers.
Thanks,
Diego
Diego,
Thanks for the information and the link to Hiren.info! I'm creating my bootable flash drive now. I'll report back if I get this to work.
I had this same issue on a Seagate Momentus 7200.2 "laptop" hard drive. I say "lap top" in quotes because it's actually in a desktop (HP Compaq Ultra-slim dc7800). I believe it was an upgrade, so it took me a while to figure out what I was dealing
with until I finally took out the harddrive and checked what company made it!
Thanks everyone!

Permission problems in my newly installed hard drive from iMac 1 TB Seagate Hard Drive Replacement Program. Is that normal?

Just got back my iMac with a brand new replacement hard drive through the iMac 1 TB Seagate Hard Drive Replacement Program. With only apps installed, no files and fonts added, the hard drive already shows permission problems. Is that normal? The replacement hard drive is a Seagate again, ST31000528BAS. Do people like their replacement hard drive?

Just now looking at these... Last recall 2009 MacbookPro Video issues, I waited 4 years and it took 4 trips to apple store with video of the machine problems... Days and months past, finally with stern discussion with manager, got resolved. Now Drive recall on work machine... better take advantage now. IF IT AIN'T BROKE DON'T FIX IT!
Should have thought of it... Have TM full back up... (will look into clone next time, now that I see this). Take in 27iMac running 10.6.8, 5-7 days, what a joke, my boss will be happy to pay for a week without working. Finally get, "if you have TM back up, 3 days." Get machine back with 10.6.3, hit the R recovery, click TM back up, runs for 2 hours, reboots, looks great. Box up take back to office... update to install - OH CRAP, still running 10.6.3. Updates crash with error on install, BUG PROBELM, nothing runs.
Call Apple... after hours, tells me to boot using 10.6.2 disk, wipe, reinstall OS, udate to 10.6.8, THEN do the restore. GREAT! Only thing 10.6.2 DVD won't read... now back on phone... take back to the store, Genius says, "Oh, can't boot a newer system w/ old disk, that's why it won't read." PROMISES it'll be fixed, if you leave it over night... GREAT!
Pick up next day, supposedly, booted to disk, wiped drive, reinstalled, updated to 10.6.8 and did the RIGHT restore... Looks GREAT... apps run and 10.6.8 OS. Back to the office... CRAP!! not running right... fonts messed up, drop box app needs new install, cocktail needs upgrade, Fetch not working, memorized paths gone... back ups locked out of permissions... ***!!
4 hours on phone with apple and still not solved. Evidently... either different account names caused problems... and/or they never restored personal "settings". Seems there are 3 ways to restor... Running Migration Assistant, Restoring after they load a new OS... or NOW WAITING for them to send me a bootable 10.6.3 disk and then boot from disk, w/o installing OS and doing a restore from TM.
Can begin to make enough stink!! So now can't back up without doing a full 400 GB back up and possibly destroying any good back ups... can't work, liek having hands tied behind back. WAITING for solution! TICKED OFF!!!

1TB External Hard drive to suffice as both bootcamp and backup?

Hey guys,
I've got a 2011 macbook pro, 16GB RAM and 500GB Hard Drive. I'm wondering if it would be possible to buy a 1TB external hard drive and partition it in half, and have 1/2 be a bootcamp windows 7 partition and the other be a time machine backup for the mac hd.
Thanks!
Calvin

If you have a 500 GB hard drive, you are going to need more than 500 GB for a Time Machine backup.

How do I connect airport extreme to seagate hard drive using windows

How do I connect airport extreme to seagate hard drive using windows?

First the AirPort Extreme Base Station (AEBS) cannot share out an external HDD attached to its USB port unless it is formatted in either HFS+ or FAT16/32. It will not work if the HDD is formatted in either NTFS or ExFAT.
If the HDD is formatted properly, when you access the AEBS with the AirPort Utility, does the HDD show up properly on the Disks tab of the utility?
If it does, then you would access the HDD as any other network share, using the following format: //servername/sharename. In the case of the AirPort Disk (a HDD attached to the USB port of either an Extreme or Time Capsule), the "servername" would be the Extreme's Base Station Name, and the "sharename" would be the volumename of the HDD.

I just purchased a new computer that runs windows 8 and it doesn't want to recognize the time capsule as an external hard drive (ie doesn't show up under my compter). I've downloaded and run airport utility, but it seems to have a hard time finding the time capsule...maybe one out of 10 times it will find it.
What's more, when I look under network infrastructure under the control panel, it shows my Broadcom ADSL centurylink Router...so I'm wondering if my modem/router combo is overriding the router function on my timecapsule and the time capsule is not being used as a router...
Any help much appreciated!

In this case the TC should be in bridge mode.
Win8 is still problematic. Try using ethernet instead of wireless. I think the drivers are poor still and it is well worth having a try via ethernet if you haven't already.
Otherwise you will need to wait for apple to release bonjour for windows 8 and airport utility.. which is not out yet.
Also make sure the windows is set to home, not work or public.. even turn off the firewall.
Open windows explorer and type the TC ip address into the address bar.. (none of which is perhaps the same.. I gave away windows at vista.. shudder)

WD 1TB External Hard Drive won't work with Snow Leopard

Hi all,
I recently purchased a Western Digital 1TB External Hard Drive. It came formatted for Windows with NTFS, but I didn't think this was a problem as the packaging stated it could easily be reformatted for Mac OS. To cut a long story short, it couldn't. When I plugged it in to my Mac (iMac 21" i3) and tried to use Disk Utility to reformat it, partition it, whatever, it just wouldn't work always returning some sort of error. I resorted to using a Gparted Live CD and succesfully formated it to HFS+ but yet when I plugged it into my Mac it wouldn't mount the disk. After following advice to let Disk Utility 'Repair' the disk, this is the output:
Verify and Repair volume “external”

If anyone knows what this means, and more importantly anything I can do to try and fix this, I would really really appreciate the help!
(Obviously I see it says reformat the disk, but this is easier said than done. Now Gparted crashes when it tries to read it and Disk Utility hangs indefinitely if I try to do anything to it)

I believe the reasons behind this must have something to do with the errors highlighted by the repair process (as copied above)- errors I don't understand.

If the drive is not seriously damaged ...
Go to Disk Utility
Click on the external Drive (not on the existing partition)
Click on Partition section in Disk Utility
In the Pane under "Current Scheme" highlite the Partition and then click the "-" (minus) sign down left.
Click on the dropdown "Current Scheme" and choose a matching scheme

My Imac (about late 2008) was running very slow and I realised I had very little memory left on it so I was advised by the online chat buddy at Apple to buy an external hard drive. I have bought a lacie porsche design 1tb external hard drive which is great but how do I transfer things on to it so my computer works faster. I woudl imagine the buggest files I have are both photos and music (all bought form itunes).
Any help would be very much appreciated?
Thanks

How much free drive space is there? Right click on the Macintosh HD folder (or however you may have renamed it) and select Get Info.
The OS needs around 10 GB for its operation, but not all of that room is necessarily always needed. Depending on how close you get to the edge, creating more free space won't necessarily do anything to speed things up. It can certainy happen, but it's mostly a myth that low drive free space is a cause of slowdowns. This applies especially to zombie suggestions you may often see here to clear a certain minimum percentage of the drive out.
My recommendation would be to keep 10 GB free, plus room for anticipated expansion of your own files. So a ballpark might be at around 20-25 GB, but your mileage may vary, depending on how you use the computer.
If you have at least 10 GB free, then I'd say low drive space isn't causing your performance issue. Of course, moving things out isn't necessarily a bad idea either, if it's really needed--but you do realize that whatever you move out to an external drive will need to be backed up as well.
First backup everything, as this may be a symptom of a failing hard drive. This won't exhaust all the possibilities for the causes of the slow downs, but here are some things to start with: Open Disk Utility and select the drive, not the startup volume. What does it say for SMART Status, verified or not? You can better check to health of the drive with the demo of SMART Utility.
Next, open Activity Monitor. It's in the Applications folder inside the Utilities sub-folder of the main Hard Drive folder ("Macintosh HD", unless you have renamed it.) Go to the System Memory tab and take a screenshot of the bottom section only. (Screenshot is Cmd-Shift-4.) To insert it into your post use the camera icon above. Being low on RAM/memory can cause these kinds of symptoms. Like this:
In addition, see if there's any process or application consuming an inordinate amount of CPU. How much CPU is idle?
