My external Seagate 4Tb drive keeps disappearing on my Windows 8.1 Toshbia X75 laptop

I have a new Toshiba X75 laptop running Windows 8.1 64 Bit. One of my external drives keeps disappearing on me and the only way that I know of to get it back is to reboot, and this is getting old real fast.
I have 5 external hard drives; drive 1: 500Gb, USB 2.0 western digital, drive 2: 2TB, USB 3.0 seagate, drive 3: 3TB, USB 3.0 seagate, drive 4: 4TB, USB 3.0 seagate, and drive 5: 4TB, USB 3.0 seagate. Drives 1, 2 & 5 are connected to a powered USB 2.0
7 port hub which is plugged into one of the laptop's 4 USB 3.0 ports; the othe two drives are plugged directly into two of the other three USB 3.0 ports on the laptop.
Drive 1 has done this once before and hasn't done it since. Drive 4 is the problem child although drive 5 has done this in the past too. Both drive 4 & 5 where purchased at the same time. At first I thought that drive 4's problem was the drive it self,
so I had it replaced, but it still is a problem child. When it was replaced they gave me a newer version of the drive too.
Is there a fix via Microsoft?
I have read that there might be some sort of a fix for the registry, but when it comes to playing with the registry, I tend to make sure that I know exactly what I'm doing before hand, and right now I don't know what to do in the regestry.
Anyone have some great ideas? 
And thanks ahead of time for the help.

This is probably the article that you were referring to with the registry fix:
"Help! After installing Windows 8.1, my USB drive disappears or file transfers
stop unexpectedly..."
This article was updated to state that the registry workaround is no longer required, as the Update has a fix in it. However, you still might want to check the power settings and make sure 'suspend' is disabled.
Hope this helps,

    I have an external seagate 2tb drive with 3 partitions each with encrypted passwords. What must I do if one of the drives won't recognize it's password?

    I would have to say the LCD display or possibly the inverter as the graphics adapter can properly output to an external monitor. This would be repaired under warranty.

  • Hard Drives Keeps Disappearing Windows 8.1

    I just recently upgraded to Win 8.1. I have 3 hdds. Win is installed on Samsung SSD. The other hdds is for software and for games. The gaming hard drive keeps disappearing. I have to restart the computer to get it show again in My Computers. Also I notice
    sometimes when I restart my boot order keeps changing. I have to go into the bios and change the load order back to my SSD to the 1st priority. Can someone help with this issue?

    Hi wjason777,
    OS related issue please consult on MS Answers http://answers.microsoft.com/en-us/windows
    Hardware related issue please contact your provider.
    For your issue, when you reboot you can press F2 or F12 to load your boot menu. However, please notice the key depends on your hardware. It migth also be F5. So you may have to contact your computer provider about this issue.
    If you can open that Boot menu. Please try search for boot order. Then you will be able to change the order.
    By the way, if SSD keeps disappear, I think it is poor contact. I will recommend you contact your provider for more details.

  • My External Seagate Hard drive just changed to read only

    my External Seagate Hard drive just changed to read only on its own?
    I went to get info and scrolled down to the  Sharing and Permissions
    But there is nothing there but a greyed out : You can only read
    There are No boxes to check or uncheck, No options to change to read and write, No name of owner or ignore ownership box. NOTHING ELSE IS THERE
    HELP!
    I have recently upgraded to Mountain Lion and am having other problems as well

    Click on the external HDD icon COMMAND+I.  You should see a display such as this:
    You should be logged on as the administrator.  Click on the lock icon.  It should open and allow you to make the required changes.
    Ciao.

  • How do I format a Time Capsule (3TB) drive for serving as an external drive while replacing its TC function with a Seagate 4TB drive yet keeping the Apple TC's wifi functionality?

    I have a hard line from my iMac to an Apple Time  3 TB Time Capsule with wifi. I wish to replace the drive potion of the Time Capsule with a new Seagate 4TB drive

    Aside from changing the type of data you put on the Time Capsule, leave its drive as is. Its format is fixed.

  • Why does my Thermaltake Silver River 5G USB 3.0 External Drive keep disappearing?

    Hi All,
    Having major problems with a Thermaltake Silver River 5G USB 3.0 External Drive (http://www.newegg.com/Product/Product.aspx?Item=N82E16817153160).  External drive contains Western Digital 2TB drive (http://www.newegg.com/Product/Product.aspx?Item=N82E16822136891).  I'm running Mac OS X 10.8.3 on a 2012 Mac Mini. 
    Basically, I can plug-in or turn the drive on, it mounts fine. Can run a Time Machine Backup.  At some point (and I think it's when the computer goes to sleep), the drive hangs and I can no longer access it.  Time Machine will hang on "Looking for backup disk".  Drive will still appear in Finder, but I cannot "Eject" it.  I've also tried to do a "umount -f" on it from the Terminal.  Disk Utility still "sees" the device and the disk (partition?), but can't run a repair. 
    The only way I've found to fix this problem is to reboot the machine.  I've crawled through the System log, but I don't see anything that points to a problem. 
    What else can I check?  I'm have no idea if it's the hard drive, the external USB enclousure, Mac OS X, or the Mac Mini that's the problem.  Please let me know if there is more information I could provide to help solve this problem.  It's really frustrating!!!
    Thanks!
    -Ben

    I received an answer from Thermaltake technical support. I asked if perhaps there was a firmware upgrade to prevent their drive from disappearing. They wrote on 22/04/2013:
    Thank you for contacting Thermaltake Customer Service.
    No firmware to do it. Just set system to never sleep. System will cut/disconnect the USB when it into sleep mode.
    I wrote back saying I have never had to do that with other USB devices. And I routinely allow my system to Sleep. Is that an issue with their drive housings? They replied on 23/04/2013:
    that is issue with sleep mode.
    I don't know if this occurs with other USB 3.0 drives and Time Machine. Somehow, I doubt it. Anyway, it sounds as though my Thermaltake is destined for eBay...

  • Backup drives keep disappearing

    the back up drives that I have associated with time machine keep disappearing. just drop off of finder and the desktop and even they are still hooked up, i cant get them back so I can access them. this includes rebooting, and turning off all of the electronics. they will randomly reappear. when they do, the time machine cannot complete the backup prior to disappearing again. I really need to back up

    Hello,
    This problem is rather difficult to diagnose without additional clues that would - fortunately - come from your system logs.
    Try to look in your system logs (Console application) for lines starting like this:
    .... kernel[0]: IOSCSIPeripheralDeviceType00::setPowerState (....) timed out after xxxxxx ms
    Other questions:
    - Are you external drives powered by the Mac or with their own power pack?
    - Are you certain you didn't experienced "abnormalities" (spike, surge, drop-outs) in your house main?
    If you do need your external drives to be up and mounted all the time - and they are on their own power supply - better to power them through an UPS (Uninterruptible Power Supply).
    This is one lead to investigate on. It may not be the answer.
    Rgds,
    Thierry

  • HP Z620 does not boot when external Seagate hard drive is connected

    I'm troubleshooting an HP Z620 workstation with 32GB RAM, one 500GB HDD + one 1TB HDD running Win 7 Enterprise 64 bits, this user has 2 external USB 3.0 HDDs,  one Buffalo 2TB  + one Seagate Desktop Backup Plus 4TB; the problem comes when the external Seagate HDD is connected and the PC is turned one, for some reason the PC does not boots, it shows a message that states "Non-disk or no boot disk error" and sometimes it tries to boot, but then goes thru the "Windows repair option" or "Start Windows normally" routine, none of these results on starting the PC.
    The only way this PC starts and works properly is when PC is started with the external Seagate HDD disconnected and then connected once the Win 7 is up and running; the problem described above does not happens with the external Buffalo 2TB HDD and the Seagate HDD have been tested throughly and no errors or problems have been detected on it.
    I'll really appreciate your attention to this, as well as your prompt response.

  • HT201250 Macbook air and 1TB external seagate hard drive

    i just bought a 1tb seagate hard drive and set up time machine to my macbook air. so just to check i went back and opened iphoto from one of my backups and the iphoto library wouldnt open. does anyone know why and how do i access the pictures from my iphoto library on my exteranl hard drive.

    I didn't think that this would happen, so I never bother backing it up to another drive. I regret it I don't want to format it, I don't want to lose what's inside it. I wish there were another way? Please, help me!!!

  • Since upgrading to Mavericks, I can't connect to my external Seagate hard drive. How to I fix this??????

    I have two Seagate hard drives that were working fine for a couple years until I upgraded to Mavericks. They connect via USB and never show up in Finder.

    I tried to connect a Samsung hard drive. Before Mavericks it was working fine. Now it won't appear in Finder and it can't be mounted in Disk Utility. As with previous issues I reported concerning iOS 7 and Mavericks, I wrote in this forum, but Apple never reacts. People are trying to help each other with workarounds, which is great, but the core issue isn't solved by Apple. It seems after Steve Jobs they're not concerned about quality that much anymore. The fact that I can't use a very common Samsung external hard drive on Mavericks is just way beyond deplorable. And what did I get in return? iBooks?

  • Can't boot from either of 2 external Seagate hard drives

    Over a year ago, I purchased two external Seagate drives. One is FireWire 800/400. The other is an eSATA 500GB connected to an eSATA PCI card. I have not been able to boot from either one of them after placing a "bootable" copy of my "main" internal hard drive on each using SuperDuper! It isn't a SuperDuper! problem because I have another internal hard drive with two partitions. I have placed the same kind of bootable copy on each of the internal drive's partitions and they boot just fine. The external drives are the problem. After a lot of back and forth with Seagate, they concluded that my boot ROM is too early (too old) and does not support booting from their drives. Their lab has a newer dual PowerMac G5 and it does boot their drives. I was told that updating boot ROM was not possible. Both external drives function very well except for the fact that neither will boot. I just read elsewhere in this forum that boot ROMs _can be updated_. Is this true? Search on "Boot ROM" and include the quotes to see the references to updating boot ROM. Is this possible with my machine? See below for boot ROM version. Thanks in advance for any info you can provide.

    Hi-
    Blaming the boot ROM is a first. Haven't heard that one before.
    Boot ROM can be updated, though it would have to be an update provided by Apple. There are no G5 updates beyond 5.1.8 (that my searches reveal, anyhow).
    I think it is best to look elsewhere for the problem....
    What are the Seagate series numbers? 7200.10?
    What is the Seagate firmware version?
    What is the make and model of the SATA PCI controller?
    What is the chipset, make and model of the firewire drive housing?

  • Seagate USB drive always disappearing from desktop

    I have a 2TB Seagate USB 3 drive, which is "backwards compatible" with USB 2.0.
    I put that in quotes because this drive constantly disappears from my desktop. I simply
    unplug the USB cable and plug it back in, and voila, there it is. But it makes me nervous
    (and ticks me off!) that it never 'stays put'. Nervous, because I have been using this drive as my
    Tima Machine drive. I just did a successful restore yesterday, so I know it's working properly, but
    I do have to manually start my backups. I constantly get the message "backup drive not present".
    So scheduled backups are sketchy to say the least. I know what you'll say - get a different drive for
    use with Time Machine.    A good idea I'm sure. But can anyone tell me why this drive won't remain on
    my desktop? Is it a USB 3 issue?
    Thanks

    There are many reports in these forums of problems using Seagate GoFlex drives with Time Machine. I wouldn't trust one, myself.

  • Files on external FAT32 hard drive have disappeared

    My friend attached her external USB hard drive to my Mac. She didn't know that she was supposed to eject her drive before pulling the USB cord.
    Now, she can't see any of her files when she attaches her drive to her Windows XP machine. She's very upset; this drive has years worth of files, including some wonderful photos from a workshop we both went to.
    I was able to attach the drive to a Linux computer, and I can see file and directory names. I wasn't able to change into any of the directories, though.
    When we attach it to a Windows machine, the drive looks completely blank, and Windows asks if we want to format it.
    What should we do?

    if the drive is still visible on your computer, copy everything to your HD and burn a CD or DVD with the data. Then you can reformat the flashdrive and copy the data back onto it.
    Obviously you have learned the lesson of never disconnecting a drive without first ejecting it.
    I have two flashdrives that I use on my MBPs and my PCs and it has never lost any data, but even a flashdrive should regularly be backed up onto something more permanent.
    Your friend obviously has been yanking the flashdrive out of her PC without ejecting it and that's a no-no also. There's an icon in the Windows taskbar on the lower right that is used to eject any portable hardware, from flashdrives to cameras, to whatever. Let her know that it is very important to properly eject the drive, no matter what computer it is on.

  • Snow Leopard on external firewire hard drive keeps crashing/freezing

    I own a 2006 iMac that came with OS X 10.4 Tiger installed and it has always been stable and reliable. Lately I had the need to use some software that only ran on OS X Snow Leopard so I installed an external Firewire (Western Digital) 260GB hard drive and put OS X Snow Leopard on it. For the first few months, everything ran fine, but as the drive slowly filled up (or perhaps with time), my Leopard external drive started giving problems, most commonly, it would lose its Ethernet connection for no reason, or I would get a line of black/multicoloured pixels appearing across my Firefox browser (or something else weird would happen to the display), followed by the rainbow wheel spinning indefinitely... this happened more and more often, when I opened too many applications at the same time, or more than 3-4 tabs in Firefox. Occasionally the screen would "white out" or go completely black. I'd have to physically switch the computer off and on again.
    However, I still have not even used 20% of the hard disk space so its not a matter of the hard drive becoming full...
    The Tiger internal drive is still running 100% fine so it's not a problem with my RAM...
    I've tried verifying/repairing the disk, but it doesn't show any problems. Any ideas about what I should try doing next?
    Thanks in advance for any pointers.
    Message was edited by: artemisworks

    Just so I understand this correctly:
    1. Your internal hard drive is on Tiger?
    2. Your external (a WD) is on Snow Leopard?
    3. Where is the "partition"? Do you have either drive partitioned?
    4. You only have the problems when you are booted from/working on something using the external drive?
    I've seen quite a few posts here regarding problems with external Western Digital drives; it appears that their internal drives are fine, but the externals do not play nice with Macs after a while (maybe the enclosure they use??).
    In any case, if your problems are only when using the Western Digital, I'd say return it if possible, get it replaced, or buy a different brand and use the WD as a not-often-needed extra backup.

  • 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.
    Intel Q6600
    Gigabyte GA-EP35-DS4 (ICH9R southbridge)
    4GB DDR2-800
    2x Seagate 320GB SATA 7200.10
    Intel X25-M 80GB
    8800GTS 320mb
    PC Power & Cooling 750w PSU

    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!
