HP Envy h8 - 1400z: lack the 2nd hard drive after windows update

Discount Windows 8 for us solve a problem.  Before the update, I had two drives of 1 TB.  The first hard drive was for the OS C: and D: for the recovery partition.  The second disc has a partition called E: and has been used for data.

After the update, I still have my partitions C: and D: as before on my first hard drive.   However, no D:.  Using disk management, the first hard disk is visible and it has C: and D:, as well as a few other partitions I do not recognize but appear to be associated with the update. Disk management does not show the second hard drive.

Starting in UEFI shows the 2nd disc and it is recognized as a 1 TB drive and I have no reason to believe that the drive has failed.

Did some research and see that others have lost a partition during the refresh, but the road is still visible in disk management.   Their problem is resolved by assigning a drive letter.  However, this does not work for me because the operating system does not see the drive.

Is it possible that refresh changed my disks in raid 1?  How I check that?  Other thoughts on how I can get my drive back?

Thanks for any help!

Hi there @AVperson

Welcome to the Forums of HP Support! It's a good place to find the help you need, other users, the HP experts and other members of the support staff. I understand that after a cooling a HDD is no longer appears in disk management. I'm happy to help you.

Since it does not appear in the BIOS but not in the operating system, let me start with a few BIOS tests on two hard drives. In fact, I suggest doing all the tests of material.

I see no reason for a system spontaneously create a RAID where there were none before. If the system was a RAID on the second drive would be a mirror of the first, and it must always appear in disk management.

After testing the system, you can always try remove the second disc and test it using a disk external drive bay on another device and see if it is readable.

Let me know what you find.

    Hello SidBloggs,

    Did you first disabled automatic updates by following these steps: http://windows.microsoft.com/en-US/windows-vista/Turn-automatic-updating-on-or-off

    Once they are off have you tried every day updates individually and you determine who updates is causing the problem with your hard drive?

    Maybe it's just that the update interferes with the driver that you have for your hard drive and it may need an updated driver.

  • How to use the 2nd hard drive internal for storage?

    Hi, I am a newbie in all of this. I would use the 2nd internal hard drive of our mac mini server (end 2012) for storage (in fact, I'll things rsync from a remote server to here. but this is not the point here.). The thing is, I don't know how to access the 2nd internal hard drive and where to start. I did all of the following commands in the Terminal, but I don't really know what they mean, and what can I do with this information. I've been Googling but most are guides on how to install a 2nd hard drive etc. I hope that the information below is enough for someone to give me advice please?

  • How to check if the 2nd HARD drive is possible on the Satellite Pro A200 PSAE7?

    Hello

    My A200/PSAE7 has a 200 GB HARD drive. For backup reasons, I would like to know - or learn to know how check - if my A200 already have the hardware support for a 2nd HARD drive, next to the slot for a 2nd HARD drive.
    In the BIOS, I see 'Toshiba MKxxx - hard drive' and 'hard drive - None '. Is the last entry in the BIOS is a sign that a 2nd HARD drive is supported and has to be put in the second location of HARD drive?

    Thanks in advance for any answer!

    Best regards
    Andreas

    You can do the following:

    Open the cover when the 2nd drive HARD so-called must be installed and check for some SATA connectors or cables. If there is an unused SATA connection so you can upgrade, if no, then you will need to backup your data on USB - HDD or whatever.

    If in the BIOS is something now, he won't say that he is physically present.

  • No satellite P770-111 no SATA cable to connect the 2nd HARD drive

    Hello!

    I bought by Satellite P770-111 3 days and was hoping to insert another HARD drive that I had in my old laptop.
    OK, I opened the plastic cover on the bottom side of the laptop and there are 2 slots of HDD (2.5 ") but a single HARD disk.
    A HARD disk that is currenty in the laptop's big 500 GB. I would like to install another, but there is a problem:
    There is no cable to connect it to the motherboard SATA.

    Basically, there are 2 slots hard drive but only a connection interface. Could you please tell me how could I install a 2nd HARD drive?

    Thank you in advance!

    Damjan

    > there is no cable to connect it to the motherboard SATA.
    The fact is that not all laptops of the same series of notebook models are equipped with the same motherboard and controllers of same.
    This means that even if there is a second HARD-drive Bay, you will not be able to use a 2nd HARD drive. You know

    The chassis is the same in all models of laptops but there are different motherboards and not all supported 2nd controller.

  • Pavilion 550-306no - for the 2nd HARD drive expansion slot?

    While thinking about replacing my old HP tractor, I browsed around the shop online for a possible new unit;

    Seems there is a box called Pavilion 550-306no, sold here in Sweden, which could meet my needs.  However, does anyone know if there is room (or not) for a 2nd HARD drive? Seems all the guides of the old user on how to develop yr PC in the forum of textbooks have been nuked.

    Concerning

    Hello

    The Specifications for the 550-306no indicate that it is not put into service for a disk hard 3.5 "2nd.  Review the information in the computer case.

    Some models will allow a 2.5 "HD or SSD to add.  See the image below.

    According to the amount of space available between the existing hard drive and the motherboard, you might be able to mount another HD using 3.5 media ".  Those that I had recommended in the past are now $40 (ouch).

  • Installation of the 2nd hard drive internal

    I have a HP Pavilion a6750y, with an internal hard drive and a LightScribe DVD Super Multi burner.  The system is running Windows 7 Ultimate 64 - bit, with 8 GB of RAM.

    I want to install a 2nd internal hard drive... If all goes well.

    The original hard drive goes SATA1 on the motherboard.

    The DVD player will SATA2 on the motherboard.

    So, obviously, I chose SATA3 on the motherboard to connect my cable purchased and only plugged SATA 2nd hard disk.  So far so good.  Now the problem...

    I did not know that the SATA drives have a power connector different than the old records.  So, a single SATA power connector goes to the original drive and the other for the DVD player.  There is no third party.

    All other power connectors are old white 4 holes plastic ones.  And like 5 of them.

    If I'm screwed?  How can I get another SATA power connector?  Are there adapters that connect to the 'old' white maybe?

    Or do I have to buy a new power supply with 3 SATA connectors on this subject?

    Thanks for our help.

    Hi Mike,.

    All you need is an adapter like the one on the link below.

  • Dimension E310 will identify the 2nd HARD drive

    I am trying to add a 2nd HARD drive on my Dimension E310 (WinXP Media Center Edition 2005) without success.  I bought a naked WD10EZEX and 1.0 TB SATA cable and have physically installed the drive and connected the power cable from Garland.  SATA data cable is connected to the SATA-2 port.  When I go into the BIOS settings, the original boot drive 80 GB is recognized but the second disc of 1.0 TB is not.  I turned on the port, but the disc ID says 'unknown '.  If I spend two readers autour, the first hard disk (CT 1.0) is recognized but the second disc (the original 80 GB) drive ID: unknown.  BIOS is version A03 (08/10/05).  What I am doing wrong or do I not have a defective SATA-2 port?

    Hi, Osprey4.  Thanks for your suggestions.  I tried to connect just one drive at a time for the second SATA port, leaving the first open port and got the same results.  No disc has been recognized.  I chose to not reset the CMOS.  It seems the second port does not work.  I can accept and manage with just one port I have available with the larger HARD drive.

    Thanks again for your support.  I'll mark this thread as "resolved".

  • Satellite Pro P70 - Has: 2nd invisible HARD drive - how to initialize the 2nd HARD drive

    I have a P70 - A. Satellite Pro
    'Primary' hard disk failed, and has been replaced by the service centre.

    Now, only the main hard drive is shown and the Service Center said that I had to 'initialize' the second hard drive to make it visible. They assure me that the hard drive is there, just hidden.

    How can I make visible?
    How do I initialize it?

    Usually, you can initialize the disk by DiskManagement.

    In disk management, right-click the disk you want to initialize and then click on initialize disk.
    In the dialog box initialize the disk, select the disk to initialize.
    You can choose to use the master boot record (MBR) or the style of partition GUID partition table (GPT).

    Once a disk is initialized, you can create partitions on it.
    After you create a partition, you can format the partition to create a filesystem (NTFS).

  • HP Pavilion Elite HPE - 580t: SATA HDD recognized and boots with the 2nd HARD drive, but not without

    Hello

    I have a Pavilion HPE - 580t with windows 7 installed.  The original drive (Drive1) has (according to Windows Disk Manager), a 100 MB system partition, a partition of 1 GB operating system and recovery partition.  The drive began to generate disk errors.  I added a second SATA (lecteur2), which has been recognized in the BIOS - it always appears at startup.

    I do not have to implement a system of lecteur2, but re-installed Windows 7 100 MB partition using lecteur2 as boot drive (not a cover), and it works fine, for most.  Reader1 still generates errors and slows down the office, but if I disconnect reader1, lecteur2 is ignored at the start, as the Bureau attempts a network boot.  I have confirmed in Windows OS is the start of the lecteur2, not reader1, but once again, lecteur2 is ignored as boot device if reader1 is not present.  I should add that this was the case when I was reinstalling the OS, I tried unplugging reader1 prior to re - install, but could not do and still access lecteur2.

    I tried to go up during the boot sequence in the Setup (F10), no change.  One additional thing - Setup (F10) is available that when reader1 is connected - F10 key has no effect at startup if reader1 is detached.  F10 Setup runs from the system on Disk1 area?  Any ideas on what I need to do to drop Drive1?

    Thank you

    David

    I can now tell you 2 things on your system.

    (1) the original hard drive is 1.5 TB and that is embedded in the tattoo of HP.

    (2) you cannot use a disk less than 1.5 TB as primary drive.

    Never seen a facility like this scheme start between readers.  The only way I see on this perdictament is to remove the 1 TB drive and let the process of recovery of re - install the operating system. Then immediately clone the original on a new disk of 1.5 or 2 t. Attention to not exceed 2 TB. Seagate and WD has a free program for Disk Wizard for cloning option.

  • Correct installation of the new hard drive for Windows 7

    Have a disk hard fatal crash with Dell OEM Windows 7on, so I bought a new hard drive compatible system and have my old system Win 7/recovery of data on a memory stick. It's been years that last I formatted, partitioned and installed an operating system on a new hard drive and I totally forgot how it's done. Vaguely remember some DOS commands were required to work out of BIOS (?). Can anyone list the individual measures to be taken, assuming that the hard drive is physically installed and turned on? It would be a great help!

    Unless this stick memory has on her installation files as well, you cannot reinstall win7 on the new hard drive

    You will need the DVD / or the ISO of Win7.

    ]

    And no you do not need BACK. Just the dvd or ISO / to boot from. Then you can format / partition in the configuration screen
