Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

What is the best Windows program/methodology to check the "reliability" of flash drives and external hard drives (HDD, not SSD--also using USB interface and not removing them)?

We have several that we use of both and just wanted to make sure they are in good shape since they get beat up quite a bit.

(I know there is no perfect method or guarantee I was just looking for something that could give a "diagnostic opinion" on them.)

I am running a Dell PowerEdge T310.  I have 2(qty) RAID 1 setups.  The Hard Drives are Hot Swap.  The first RAID runs the O/S and the second my data.  One of the drives in the first RAID has a blinking amber light and states there is a predictive failure.  I can see this through the Dell Server Admin login on the Server O/S.  I am purchasing a new drive that is the same model, size and speed. My question is do I simply just pull the Hard Drive with the Predictive Failure out and insert the new one or should I run the Dell Server Admin and set the Predictive Failure drive to offline and then replace?  What would be the safest/proper way to replace this drive?
Just installed new Esxi host running 6.7. Everything looks green.  All datastores are present.  All networks have portgroups.  But when i try to vmotion i get :

Failed waiting for data. Error 195887167. Connection closed by remote host,

I confirmed vmotion enabled on iscsi and management portgroup just for sake of troubleshooting.   Any help would be great
I am trying to replace a failed disk in a raid 1 under windows 7 pro. I had to physically remove the disk before the machine would boot up properly. I then went to disk management and removed the failed mirror. I then installed the new disk, initialized it as a MBR disk and converted it to Dynamic.  I set up a partition of the same size as the original disk, but when I right click the original disk, "Add Mirror" is greyed out. If I delete the partition "Add Mirror" becomes available but when I try to add the  unallotted space to the mirror, I get an error message that the disks have to have the same partition size and sector size and type.  What am I doing wrong. Thanks for any and all help.

Hi there,

I´m struggling with an issue on my exchange server 2007 regarding a database that is in a dirty state. the problem is that this DB file is on a server with a RAID 0 and one of the disks is failing. I´ve managed to force the disk to "malfunction" in order to be able to get the file from it. If I manage to get a copy of the file (db.edb) (the log files are in another drive) will it be possible after rebuilding the RAID with another disk and restoring the volume name and file to access the exchange console and do an ESEUTIL to try to repair the excahnge DB? how can I recover my mailboxes? this is URGENT as we only work with emails and as I write this everything is stopped
Hi Guys,

I have an interesting issue, after replacing a faulty HDD and allowing the RAID to rebuild successfully, a single user mailbox acted weirdly and i had to investigate and follow the usual routes and causes. Ultimately nothing worked an i created a new user in AD with a new mailbox account which was working correctly,

The disconnected mailbox will not reconnect to any other user account and i am afraid it may be corrupted, but before i pull the plug i thought of asking for help. Following is a shortened version of the message i got on the user pc, in hindsight i should have gone offline end exported all to PST but........
"Your mailbox has been temporarily moved to ... A temporary mailbox exists, but might not have all of your previous data. You can connect to the temporary mailbox or work offline with all of you"

Any solutions or suggestions or even is there a fee tool to convert an ost to pst??
We bought a laptop w/ 30 GB HD & Windows 10. Unable to get Windows 10 updates due to lack of storage space. Only 1.79 GB free.

I am trying to diagnose an occasional paging file error I am receiving on an HP Proliant ML150 Gen 9 server running Windows 2012 Server R2 Standard.  The warning message is:

warning:  eventid 51
An error was detected on device \Device\Harddisk3\DR291 during a paging operation.

I am trying to figure out which physical or logical device this is pointing to on the server.   Note that the number following DR changes every time there is an entry for this paging error in the system logs.

 I took over administering this server earlier this year.  The server uses an embedded B140i RAID controller for the physical drive connections. The physical disks are set up as follows:

4 X 1 TB SATA drives in RAID-5 array, total available storage c. 2.7 TB
array is split into 2 logical drives:  

  drive C: at c. 400 GB
  remainder is drive N: at c. 2.3 TB

There is also an external Seagate USB 5 TB drive, total available storage c. 4. 7 TB, split into 2 logical drives:

  drive X: at 2.3 TB
  remainder is drive Y: at c. 2.4 TB

I'm attaching a PDF with screen shots of the DISKPART  screen showing disks and volumes as the server sees them, Computer Management / Disk Management screen, My Computer / Drives screen, a Device Manager disk drives summary, and also a tech doc at the beginning of the PDF that provides some decent info on this message but doesn't quite solve it for me.  As per the recommendation of the tech doc I also ran a WMOBJ listing of the …

I have 5 Kingston KC300 240 GB SSDs.  I have a LSI Megaraid 9285CV-8e RAID card version 5.5.  My motherboard is ASRock E3C204-4L with latest available BIOS.  

The SSDs are not detected by the RAID card.  I also tried a Seagate 1 TB HDD and also did not detect it.   I loaded the UEFI defaults in the BIOS but they are still not detected.  On bootup the POST screen says 0 logical drives detected and after logging into the server and launching ServerView RAID Manager, it sees the card but no drives.  All 5 drives are connected to the ports using SFF8087 cables.

Any suggestions?
Migrating a VM that has RDMs. I want to perform a storage migration of 2 VMs that are paired in a Windows failover cluster. All I am d0in is moving the VM Files to another Datastore.. I am not touching the actual RDMs. Will this pose a problem or will the mappings for the second VM (using Existing Disk for RDM) update automatically?

-Need to migrate off of 5.5 Standard to 6.5 Standard
-Consolidating from 3 hosts (5.5) to 2 hosts (6.5)
-30 VM's total
-Brand new environment...new hosts, new vCenter has already been stood up by consultant, new storage.  
-Networks can see each other...all routable subnets between each other.

Old environment: vCenter 5.5
New environment: vCenter 6.5

I am trying to figure out the best way to migrate these VM's.  There are currently no NFS datastores set up on either end...it's all VMFS5.  The old environment is a 3Par and the new one is a Dell VRTX environment.  Downtime is not an issue, but I am trying to think of a more efficient way to get these VM's moved over besides using OVFTOOL or Standalone converter.  Am I overthinking this?  Should I just present a new NFS datastore from the old environment?
Hi experts,

I have this example.
It uses jQuery.
So when I click the button it saves a variable to local storage.
Then with the other button I clear the local storage.
It works fine.

How do i do the exact same thing but only using pure javascript. Without using jQuery.
I have a legacy application that doesn't have the jquery library and I can only use JavaScript.

I tried to re-map a datastore, that is to say I tried to change its initiator group on my storage system. which caused the host to lose connection to the datastore, unfortunately there was a vm running at the time.  I got errors in vCenter complaining the vm could no longer see its disks.  I then removed the vm from the inventory and re-added it.  The datastore is accessible again and all the virtual disks are still there.  However, now I cannot power on the vm and get the following error:  "The object has already been deleted or has not been completely created".  

Not sure what to try next.

Best Ever Paul M
This is using IBM storwiz v3700 storage. The SSH service is available and we can connect with this SSH by using the assigned user account with correct password. BTW, how to change so as instead of using password, create the key-pair for the dedicated user account?

Thanks in advance.
Can I change the block size of the disk when I use VMware converter?

So lets say for example, I have a vm in one datacenter in vcenter, and I want to use VMware Converter to migrate it over to another datacenter.  The goal here is to be able to change the block size of the virtual disk from 4K to 8K block size.  This is for Deduplication Optimization that Simplivity uses on the destination Datacenter

Please give me your thoughts!  thanks!
Hi I have some servers that are using software raid on Server 2012 R2.  I was looking for a software program to email me if one of the drives goes south.

Please provide me with guides on where to download and how to configure HP ProLiant DL360 Generation 10 servers so I can view and configure their RAID settings within Server 2016.
Dell PowerEdge T620 Failed Disk. The server boots up to a foreign configuration. Asking to select "C" or "F". The system will boot up after selecting F to import foreign config. Server 2012r2 boots up then blue screens critical process died. The system config shows that the virtual disk is offline and 1 disk is ready and 1 is foreign. I am attaching pics of the config page. I have a new drive to install for the one that has the amber light  flashing on it. Any help on getting the RAID fixed and server started would be awesome.

Hello, I have Backup Exec 2012 Version 14 Rev 1798
I got the following error:
I have the following error: The disk is out of space.  As retention periods expire for backup data on the disk device, Backup Exec re-uses the disk space.

To provide more disk space, you can create additional disk storage devices on other drive letters.  You can also delete the backup sets disk that are no longer needed from this disk storage device.

Open in new window

Yes the F:\ drive is full...

And this is Disk storage 0003

I am wondering how do i find the backup sets that are targeting the F Drive so i can delete them ?

I am deleting some backup sets...but the drive is not decreasing....

See attachments.

Thanks for your help
