Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Hi all,

I have been searching online for an answer for this question for a few days now with no luck and I am hopeful that someone here can answer it for me.

So, I have a Seagate Wireless Plus device that I encrypted using Bitlocker full disk/drive encryption. When I plug the drive into my desktop computer using a USB, I am required to enter the encryption key to access the drive. It works fine and I am happy with this.

However, I am wondering if the encryption extends to wireless access. In other words, if someone connects to the device while it is broadcasting its SSID (by default it does whenever it is powered up), would they be able to access the contents or would it be all a jumble to them?

Please note that I do not have any compatible wireless devices to test this on hence my reason for posting this question.

TIA
~Tala~

Just got a new ZBOOK G4 and i added my old sata HHD (that was on my old ZBOOK) but somehow the HHD is not detected in the BIOS ... is there anything special we need to do on the hardware in order for the second drive to work ... (other than placing the HHD in the caddy and place the drive inside the laptop of course)

The hard drive is from an NVR (Network Video Recorder) and the manufacturer indicates that the drive is handled as UBS - Uniview Block Storage.  The drive has been pulled from the NVR and works properly in another (same model) NVR, but I'm looking to access the drive on a desktop computer in order to pull files stored on the drive...  This is a SATA (8TB) drive...

Anyone have any advice on potential ways to mount this device in Linux or other O/S that might allow me to access these files, or other meaningful suggestions?  Thanks in advance.

I have a Perc 5/i installed on a PowerEdge 1900.  I have four 750gb hard drives that are in a RAID5, potentially.  The Virtual Disk was initialized and when I just hit the Enter key on Controller 0 I am told:

Configuration is not allowed!
ERROR Code: Unknown

There are no errors outputted on the tiny screen.  Yesterday it told me that the ROMB battery was dead, so I replaced that, and now no more errors.  However, there is this problem now.

I'm looking for a bigger SSD for my current desktop setup and I'm finding the pricing all over the place.  It appears to be tied to the read, write and IOPS speeds.

My question is will I be able to notice and IOPS difference of 10-20k or a read/write difference of 50MB?

I'm trying to decide if spending and extra $100-$200 is worth it.  I know my hard drives are biggest bottleneck on the machine, so looking for suggestions.

Current Drive I'm looking at: https://www.newegg.com/Product/Product.aspx?Item=N82E16820147361

Any better suggestions welcome as well.

I have an old PowerEdge 1900 that has a Perc 5/i in it.  I go into the configuration utility and select RAID5 for setup.  I have 4 750gb hard drives, so it comes out to 2.2 tb, or close to it.  I initialize the disk and when that is done I step through the rest of the process and on the last page I select "APPLY" then CTRL+ALT+DEL to reboot.  Upon rebooting there is a message that says "All of the disks from your previous configuration are gone".  It tells me that there are 0 logical drives on the host adapter, and obviously, 0 logical drives handled by BIOS.  What is the issue?

hi,

can you recommend a good wireless memory 1T or more?

Thanks.

Hi,
 
 I have HP DL360 G5 server with P400 SAS RAID Controller with five 147GB hard drives. It is running VMWare ESXI 5.1. One of the hard drives failed and it showed in amber color. I replaced the bad hard drive in timely manner, but I like to be able to monitor RAID status in a graphical fashion. Beside the VMWare box did not even beep when the hard drive failed.
 In VMWare box, I have several VMs - Windows 2008, Windows 2003 and XP desktop IS.
 I can also utilize a separate workstation PC (running Windows 7 or 10) to run RAID management software if necessary.
 Can you guide me into the right direction?

Thanks.

On Demand Webinar - Networking for the Cloud Era

This webinar discusses:
-Common barriers companies experience when moving to the cloud
-How SD-WAN changes the way we look at networks
-Best practices customers should employ moving forward with cloud migration
-What happens behind the scenes of SteelConnect’s one-click button

I have purchased plenty of external drives and never had a problem making them work with Time Machine. Until now.

I pleaded in the drive, selected "Encrypt", added the password...

I was then told it would delete everything on the disk and said OK.

Then, it generated an error.

When I insert the drive get the attached error:

Disk error
What shall I do next?

Thanks

Microsoft advises me that backing up a Windows 10 computer to achieve full restore, if required, is best done with an external hard drive that contains an app designed for this purpose.

Experts, please, identify and comment on external hard drives that contain the app.

The external hard drive must be able to store and restore everything needed for Windows 10 to be installed on a new internal hard drive that is a replacement for its predecessor that totally failed.

Thanks

The drive has a System reserved partition of 100 MB and the other partition that has the Windows operating system.

Do you mark the system reserved partition as the boot partition or the partition that actually has the OS?

How do you set these parameters on an OS drive w a reserve partition.

System, Active, Boot, Primary

Right now when I try to boot off of it, it complains it cannot find winloader.exe.

Thanks so much,

Steve

I have a system that I built myself with a GigaByte mother board.

I set the BIOS to have boot order be the USB Thumb Drive and then the CDRom but it just goes right by them into the Windows Boot disk.

I have booted from them before so I believe that they are good but just goes right by them.

I need to boot into Norton Ghost 15 recover to restore my system after a Samsung SSD failure.

I am going to try and build another CD boot disk, Link to good procedure would be awesome.

Is there a utility that can manage the boot or a known good boot iso image that I can download?

See photos of Bios Setting attached.Booting-to-Usb-fails.pdf

Thanks,

(Disclaimer: I'm not an Oracle expert, I'm a sysadmin assisting our DBAs with this issue)

So this is a real head scratcher.  We're rebuilding an Oracle analysis cluster after a major storage hardware failure.  There's a shared staging iSCSI mount that's set up to be shared between all the compute nodes and set up through multipath/ASM as an OCFS2 partition.  When we attempt to load the previous backups from the staging partition, we get the following error:

The head scratcher is that:

1. We attempted this with one of the backups and it failed, so we ended up making our own test dump file to further test to make sure it wasn't the backup file that was bad.

2. This error ONLY when loading files from the OCFS2 partition.  I set up a second iSCSI share that was just formatted as ext4 and impdp loads the dump file just fine.

3. We've deleted and recreated the OCFS2 partition with several different cluster sizes and whatnot and we always get the same error back.

4. I can read and write to the filesystem on the staging partition just fine.

File permissions are as follows:

Any ideas...?

Hello Experts,

Does anyone know the procedure for backing up the Raid module configuration on a Dell MD3260?  We are replacing the Raid module controller battery and have it listed in the steps to save a copy of the configuration file in the MD Management console but it does not have any further instruction.

Thank you,

I have an HP MSA 2040 and I just inserted a replacement drive and I want to start the rebuild.  I know it's supposed to be automatic, but is there a way to manually start the rebuild and is there a way to monitor the rebuild?

Thanks

what is the best was to ensure that you get the correct component needed for a machine?

i typically need to replace or upgrade RAM, hard drives and display screens.

i have used cruicial.com for RAM and hard drives as the side has a scan feature but was told that isnt a great idea for security reasons.

i mainly work on windows machines (running win 10 pro) but also work on some imacs

NFR key for Veeam Agent for Linux

NFR key for Veeam Agent for Linux

Veeam is happy to provide a free NFR license for one year.  It allows for the non‑production use and valid for five workstations and two servers. Veeam Agent for Linux is a simple backup tool for your Linux installations, both on‑premises and in the public cloud.

This drive clicks constantly, about once every two seconds. I am suspecting a driver problem as

a. the drive checks out as being sound
b. the problem doesn't happen when it's being used under Linux

Any suggestions?

This problem just recently appeared and I can't figure out what is going on.

First some specs:
- Core i5 @3.8 GHz, 32GB
- Windows 10 Pro - 64bit
- MediaSonic ProRAID box on eSATA

Writing to other drives is at typical speeds.

The problem appeared just recently where moving mixed data files (various sizes from 1MB to 1GB to the MediaSonic will begin writing at around 70 MB/s and withing 20 seconds, the write speed will fall to between 600 KB/s to 4 MB/s. This isn't normal and in the past, I could sustain an average write speed of ~ 90 MB/s.

Observed:
- If I cancel the write operation, the drive will continue writing for a long time (20 minutes) - it appears to have a backlog of files still writing - when looking at the resource monitor.
- Task Manager shows 100% utilisation until all the writing is completed.

What I am reasonably certain about:
- No known changes to the computer.
- No error or RAID failures on the MediaSonic.
- Read speeds on MediaSonic are normal.
- No viruses.

What I've tried:
- Shutting down Windows 10 notifications (lot's of chatter about that).

NOTE:

The one characteristic that has changed is that I enabled Windows 10 disk compression on selected folders of the MediaSonic volume.
I just did some testing and found the following:
- Writing to a compressed folder: sustained speed average: ~ 1.5 MB/s
- Writing to a non-compressed folder: sustained speed average: ~ 16 MB/s

In both cases, the …

I typically configured my spinning hard drives for the OS and Data files as Raid 1. If something happened then I just swapped out the drive and kept working.

When I got the SSD drive for the OS I could only afford the one drive. Now the prices have come down and I was thinking of again using Raid 1, for availability.

Talking with Samsung Tech Support they said that it would work but that they don't recommend it due to the fact that it would shorten the life of the SSD.

Having just had the drive fail and while waiting for the replacement I am thinking of getting my system up with a new SSD and when the replacement ships putting it in a Raid 1 set.

Recommendations?

Thanks,

Steve

We are using EMC VNX 5300 which is running out of space. It also hosts CIFS shares which are heavily nested. Plan is to add another DAE, have quota enabled file system and move CIFS shares to the newly allocated space. Any suggestions on how this can be achieved with minimal efforts.

As per understanding:
1. Add new DAE via Unisphere.
2. Create a new storage pool. (RAID 6+2)
3. Provision new LUN and create volume.
4. create file system.
5.create mount point and mount on datamover.
6. create quota trees.
7. Create cifs share.
These parameters to be identical to the existing file system from which data will be copied. And,

If this looks okay, any inputs on next procedures..  Thank You!

I'm not sure if the 4TB WD HDD I just got from Amazon is GPT or MBR partitioned but looks like the
driver was auto-installed Ok on my Win XP as "Safely Remove Hardware" detects it & I could 'Stop"
it from "Safely Remove Hdw".

However, using "Disk Management" & despite "Rescan Disks" & "Refresh", can't detect it.
in command prompt,  Diskpart's   "List disk" can't detect it too.

I have other 2TB disks which could be detected & formatted on this Win XP laptop.

How should I go about using this 4TB WD HDD?
