My xserver had a bad HD. I replaced it, but it will not do an automatic rebuild of the new drive. I checked for the manuel rebuild option but can find it.

Are you sure RAID is configured for your drives, determine if disk tolerance is in place and find out the level of disk tolerance in place. If No disk tolerance is configured, you may not be able to rebuild the failed drive.

I have a Gen 8 Hp server with 5No 600GB HDD. The first two disk are mirrored, the other 5 are on raid 5. 1 of the 3 on raid 5 is flagging amber colour. How do I replace the HDD without losing Data?


Before replacing drives • Be sure that the array has a current, valid backup. • Confirm that the replacement drive is of the same type as the degraded drive (either SAS or SATA and either hard drive or solid state drive). • Use replacement drives that have a capacity equal to or larger than the capacity of the smallest drive in the array. The controller immediately fails drives that have insufficient capacity. In systems that use external data storage, be sure that the server is the first unit to be powered down and the last unit to be powered up. Taking this precaution ensures that the system does not, erroneously, mark the drives as failed when the server is powered up. Replacing drives The most common reason for replacing a drive is that it has failed. However, another reason is to gradually increase the storage capacity of the entire system. NOTE: In fault-tolerant configuration, hot-plug hard drives can be replaced when server is ON, but in case of a Non-hot-plug hard drive, it should be replaced when server is OFF. For systems that support hot-pluggable drives, if user replace a failed drive that belongs to a fault-tolerant configuration while the system power is on, all drive activity in the array pauses for 1 or 2 seconds while the new drive is initializing. When the drive is ready, data recovery to the replacement drive begins automatically. For systems that support non-hot-pluggable drives, if user replace a drive belonging to a fault-tolerant configuration while the system power is off, a POST message appears when the system is next powered up. This message prompts user to press the F1 key to start automatic data recovery. If user do not enable automatic data recovery, the logical volume remains in a ready-to-recover condition and the same POST message appears whenever the system is restarted. Automatic data recovery (rebuild) When user replace a drive in an array, the controller uses the fault-tolerance information on the remaining drives in the array to reconstruct the missing data (the data that was originally on the replaced drive) and then write the data to the replacement drive. This process is called automatic data recovery or rebuild. If fault tolerance is compromised, the controller cannot reconstruct the data, and the data is likely lost permanently. Time required for a rebuild The time required for a rebuild varies, depending on several factors: • The priority that the rebuild is given over normal I/O operations (user can change the priority setting by using HP SSA/ACU) • The amount of I/O activity during the rebuild operation • The average bandwidth capability (MBps) of the drives • The availability of drive cache • The brand, model, and age of the drives • The amount of unused capacity on the drives • For RAID 5 and RAID 6, the number of drives in the array • The strip size of the logical volume • Firmware versions of the Smart Array Controller and Hard Disk Drive • Presence of BBWC/FBWC CAUTION: Because data rebuild time may go upto the rate of 200GB/15 minutes, the system could be unprotected against drive failure for an extended period during data recovery or a drive capacity upgrade. When possible, perform rebuild operations only during periods of minimal system activity. When automatic data recovery has finished, the drive status LED changes from flashing green to solid green. If the drive status LED on the replacement drive changes to flashing or solid amber, the rebuild process has terminated abnormally. If an abnormal termination of a rebuild occurs, identify the cause and appropriate corrective steps. Abnormal termination of a rebuild If the activity LED on the replacement drive permanently ceases to be illuminated even while other drives in the array are active, the rebuild process has terminated abnormally. The following table indicates the three possible causes of abnormal termination of a rebuild. Cause 1: An uncorrectable read error has occurred. 1. Back up as much data as possible from the logical drive. CAUTION: Do not remove the drive that has the media error. Doing so causes the logical drive to fail. 2. Restore data from backup. Writing data to the location of the unreadable sector often eliminates the error. 3. Remove and reinsert the replacement drive. This action restarts the rebuild process. If the rebuild process still terminates abnormally: 1. Delete and recreate the logical drive. 2. Restore data from backup. Cause 2: The replacement drive has failed. Verify that the replacement drive is of the correct capacity and is a supported model. If these factors are not the cause of the problem, use a different drive as the replacement. Cause 3: Another drive in the array has failed. A drive that has recently failed can sometimes be made temporarily operational again by cycling the server power. 1. Power down the server. 2. Remove the replacement physical drive (the one undergoing a rebuild), and reinstall the drive that it is replacing. 3. Power up the server. If the newly failed drive seems to be operational again: 1. Back up any unsaved data. 2. Remove the drive that was originally to be replaced, and reinsert the replacement physical drive. The rebuild process automatically restarts. 3. When the rebuild process has finished, replace the newly failed drive. However, if the newly failed drive has not recovered: 1. Remove the drive that was originally to be replaced, and reinsert the replacement physical drive. 2. Replace the newly failed drive. 3. Restore data from backup.

How do I install new Hard Drive in my Compaq Presario cq5320PC Desktop


Hmm Well I cant seem to find your computer model anywhere on the Internet.... but assuming its a basic compaq Computer All you would need to do is buy the correct type of Hard Drive (Ide, sata) open the computer up with the power unplugged and static protection..... now some computers have multiple Hard Drive bays and some only have one so you will need to install your new HD into a bay assuming your replacing your current HD you would remove the old HD and install this one in its spot dont forget to Check the jumper setting on the Hard drive to either match the drive your replacing or as a Master in a single HD setup also plug in a power source and the data cable into your new drive or it wont work.... it should be that easy almost all new computers will automatically configure it in the cmos for you.... if its a replacement for your main HD then it will need You to install an Operating System on it before you can use it.

BOOTMGR IS COMPRESSED


Validate and Fix the File System
This runs the check disk program to detect and attempt to repair problems on one partition. For example, to repair the C: drive:
At the prompt type chkdsk c: /r
Repair the Boot Process
Typically this is used if Windows doesn't start and you can't get to the safe mode menu. You might also replace the Master Boot Record (MBR) and boot sector if you suspect a virus infection. There are four options:
New MBR - Insert a new generic MBR without changing the partition table.
At the prompt, type: bootrec /FixMbr
New Boot Sector - Insert a new Windows 7/Vista compatible boot sector. It will automatically insert the right type of sector for the file system type (NTFS, FAT32, etc.)
At the prompt, type: bootrec /FixBoot Rebuild BCD - Rebuild the Boot Configuration Data (BCD). The BCD controls which partition boots. This option will let you select which installations to include in the BCD.
At the prompt, type: bootrec /RebuildBcd Find OSes - Scan the system for all OS installations that are compatible with Vista/2008 and will also show those that are currently included in the BCD.
At the prompt, type: bootrec /ScanOs
in the end type in C:/expand bootmgr temp

Dell poweredge t110 Raid 5 setup on PERC 100 raid config in bios stating Virtual drive degraded and drive 2 is in ready state...how do we remove from drive array and install a new on without data loss


In a RAID 5 config, you need at least 3 drives (you can have more however). A small part of every drive is then reserved for recovery data for the other drives. So two drives together hold all the data needed to restore a 3rd drive.

The Raid Controllers in the Dell Poweredge Servers are hot swappable. So you can just pull the faulty disk and then insert a new replacement drive in the same slot (Needs to be the same type and size or bigger. However, if the disk is bigger than the other 2, then only the size of the two other disks will be used on the new drive). The Raid controller will then see that there is a new disk and automatically start the recovery process. You will be able to see this when you open the Controller software. Once the recovery is done, the RAID 5 will be fully functional again.

While one of the disks is faulty or missing the two remaining disks will continue to work, but at the severely degraded performance. After the rebuild the performance will be back to the way it was before.

The rebuild can take more than an hour, depending on the disk sizes used.

There is also an option on some Controllers to select one drive as a "spare". Then you insert one more disk and set it as spare. It will not start working unless one of the other disks in the Raid fails. That's when it is used automatically as a replacement.

I have bad sectors in my hard disk what should can i do?


There is nothing you can do about bad sectors. The Hard Drive itself, with its associated electronics, automatically maps these bad sectors and doesn't use them any more. So, the answer to your question is "NOTHING". Bad sectors may eventually make your Hard Drive unusable, and if your bad sector count is growing quickly it's time to do a complete backup and replace the drive.

I have a acer 5100 aspire that won't recognize the hardrive half the time and won't find some of it's usb ports. I have reloaded windows and even tried different hard drives (used not new) and it seems to...


Do the following:

  1. Check in the BIOS to make sure that the HD is present in the system before proceeding..
  2. If not then power off the laptop and then carefully remove and replace the HD from and to its connector.
  3. Then secure it then reboot the laptop.
  4. Check the BIOS settings again to see if the HD is recognised.
  5. If you still can’t see the HD then obtain a USB to IDE / SATA adaptor cable from eBay or your local PC store and remove the HD from the laptop and lay it down on a flat horizontal surface and use the adapter to connect to the laptop’s HD and connect the USB to another PC. This will show if there are any issues with the HD itself and will allow you to format it if necessary.
  6. Then replace it back in the laptop and all should be well.
  7. If not then you can suspect that you have an HD controller issue which is a very costly repair in a laptop.

  1. If the laptop will boot or you have a bootable CD / DVD then change the boot sequence in BIOS to be CD/DVD then Hard Disk.
  2. Reboot the laptop.
  3. Once booted look at the Device Manager to see if there are any errors showing in the Storage Devices and the Hard Disk in particular.
  4. Then go to option 5 or use the bootable CD / DVD to reformat and rebuild the hard drive.
  5. If all the above fails then install a new Hard Drive, format it as required and reinstall the Operating System and applications.

Installing a new HD will I have to re-install windows?????


No, a new hard drive means you'll have to re-install Windows from the CD's that originally came with the notebook (or a retail copy of Windows as well) and all of the programs and files that you had before.  A new hard drive is totally blank.

Not responding hard disk


The problem is that the hard drive cannot be read properly.

The list of the things that may produce such a problem is bad power supply, bad data cable, bad mainboard, too many unproper shutdowns that damaged file consystency and bad hard drive (the HD electronic board or the inner plates), anyway, if you can get windows to load up run a check disk with the windows utility here are the steps

1) press START
2) press MY COMPUTER
3) right click on the drive and choose PROPERTIES
4) press the TOOLS tab
5) press CHECK NOW
6) tag (V) both options you get in the new menu--AUTOMATICALLY... and SCAN...
7) if it is your primary HD you will receive a notice that the function cannot be performed at this time, answer YES
8) turn off the computer and restart
9) the check will start automatically on computer restart

If the problem continues BACKUP any important data (if you can) and take it to a repair shop, make sure they BACKUP your data BEFORE they try to solve the problem.
