[SOLVED] Shredding a Hard Drive

I recently used the shred command on a hard drive like so,
shred -vfz /dev/sda
The whole process took several hours so I assumed it went well, but then afterwards when I looked into the drive with cfdisk I noticed that the partitions were still there. Does that make sense? Or does that mean that shred didn't actually work?

man hdparm
--security-erase PWD
Erase (locked) drive, using password PWD (DANGEROUS). Password is given as an ASCII string and is padded with NULs to reach 32 bytes. Use the special password
NULL to represent an empty password. The applicable drive password is selected with the --user-master switch (default is "user" password). No other options
are permitted on the command line with this one.
--security-erase-enhanced PWD
Enhanced erase (locked) drive, using password PWD (DANGEROUS). Password is given as an ASCII string and is padded with NULs to reach 32 bytes. The applicable
drive password is selected with the --user-master switch (default is "user" password). No other options are permitted on the command line with this one.
You can use the parted magic boot cd for example. It has a GUI for this erasing method and it's pretty fast :-)

Solved - D Series Hard Drive Tray interchange

All,
I think I've solved the mystery of the hard drive tray interchange for at least the D10 (I don't have a D20 or D30 to compare with, but I think they're similar).
When I was taking my system apart for spring cleaning to evict all of the dust bunnies, three of the five hard drive carriers/trays/brackets broke on the way out. Bad design? I'd have to agree... however, there's an upside.
On a whim, I had my old IBM IntelliStation Z Pro (Model 6221) apart and decided to try the tray from that system in my D10... fits like a charm. The casting is slightly different in that the Lenovos are black (IBMs are blue) and the markings on the sides of the rails are different. Functionally, exactly the same.
And now, the challenge ... I've been looking for these trays for my Z Pro for a while now and haven't been able to find a sane price for these trays. IBM's CRU part number is 23P1328.
Here's the page that shows the details:
http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-45808
For those who are thinking that there's a very similar blue tray out there that was used in the NetVistas, that tray (markings UL:T1055 23-931P(5) 2000A515) does NOT fit. The rails themselves are too thick to work in the rail spaces provided in the D10 or my 6221.
So, if anyone has a source for well-priced 23P1328s for those of us who are out of warranty, I'm all ears. I'd rather not spend a lot of money on a miscellaneous parts kit (41R5630) when I only need one part out of it.
Thanks,
--- A

Guess I broke the trays wrong since the three that I broke all snapped between the indicated pull surface and the rail spar.
Under appropriate pull tension, the curved center area didn't have the rigidity to pull the rail spars in far enough to allow the drives to disengage from the chassis (in my experience).
My only question was why there wasn't a pseudo-hot swap backplane used - turn the drives around and have them snap into the connectors on the far side of the removable door. Seems like that would have been simpler and you could do your cable runs from the SAS or SATA to a sort of patch-panel in order to make sure things were on the right controllers.
And honestly, if that's my only complaint with the D10... (and it is)... it's one hell of a machine.

[Solved] E4200 - External hard drive not recognized

My external hard drive, a 2TB WD Elements, does not appear in the storage list in the web utility of my E4200. The drive is formated as NTFS, single partition. It works fine if I connect it to a computer.
If I connect a 4GB USB flash drive (FAT32) to the router, it does appear in the list.
I'm using the latest firmware, version 1.0.02.
Edit: Down(up?)grading to firmware version 1.0.01 fixed the problem.

not surprised. I was going to reccomend you dropped down too. But I see you fixed it. Kudos to you. Im glad it works. Lots of drives dont work with the E4200.
please fix the E4200 media server in .02 firmware

[SOLVED] Possibly dead hard drive or bad raid setup...

I have a 4 drive raid5 running. Just recently one of the drives kept removing itself from the array. I have re / formated / partitioned the drive multiple times, but either mdadm doesn't accept the drive, or it accepts, resyncs, and when i try to access the raid it fails again.
I eventually pulled the drive out and plugged it into my desktop machine. That machine recognized the partition fine. However after putting the drive back into the raid i receive these sort of errors on startup:

I have tried using SMART to test the drives, however all the drives seem to fail with some sort of error. I believe this is a false positive as I have read elsewhere that the 1TB Green Western Digitals (WD10EARS) seem to have problems with SMART.
Is this drive dead? Its only a year old... and unfortunately just out of warranty.

Ok so i zero filled /dev/sde, and re-added it back to the array. It synced (for 2 days), and then my RAID5 completely failed. I can't bring it back up at all now. My BIOS says one of the hard drives is dead (SMART error). Fair enough drive is dead. But now i cant get the 3 drives back up and running in the RAID.
I have attempted the following:
sudo mdadm --assemble -vv /dev/md127 /dev/sdb1 /dev/sdc1 /dev/sdd1
mdadm: looking for devices for /dev/md127
mdadm: cannot open device /dev/sdb1: Device or resource busy
mdadm: /dev/sdb1 has no superblock - assembly aborted
It complains that every device does not have a superblock?

The device I'm adding is a 200gb hard drive PATA drive, the current system is on a SATA drive. There are no other drives on the PATA chain. Any advice? I'm thinking maybe grub is calling it?!?!

Try labeling your partitions from a live cd, and use /dev/disk/by-label or some other form of persistent device naming. Sounds like typical linux kernel drive controller issues.

How to Solve Problem Restoring Hard Drive on Disk Utility?

Hi everyone, my hard drive recently crashed. I got a new one placed in my computer, and I'm trying to recover data off of the one that crashed and transfer it onto my existing hard drive (which is larger in capacity than the one that crashed). I got this crashed hard drive tested, and the data is still intact; I was told that it will be possible to recovery data off of it. I bought an enclosure to place my crashed hard drive in, and I connected it to my MacBook Pro using a USB cable. Disk Utility then automatically opened. Upon going to the restore window in Disk Utility, I'm unable to drag down the name of the crashed hard drive into the source window, nor my existing hard drive into the destination window. No error message comes up; Disk Utility simply won't let me drag the names of these drives into these respective fields. Does anyone know how I can get Disk Utility to let me drag each respective drive into the source and destination fields? Thanks.

I don't know if Disk Utility is going to be of much help - you may want to try rescuing your data using Data Rescue 3 or some other data recovery application. I've tested Data Rescue 3 and found that I had excellent results.
Good luck,
Clinton

[SOLVED] (hopefully) USB Hard drive disconnects

I have a 2TB SATA drive which I used in a stationary computer (as a server). The drive is encrypted using LUKS and for a filesystem I use xfs. Unfortunately that computer died, so I figured I'd migrate everything over to a laptop instead. I put the 2TB SATA drive in an USB drive adapter, and it worked as it expected.
Until a few hours after when I suddenly couldn't use the drive any longer. It always happens after I haven't used the drive in a little while.

At first I figured the drive was suspending, so I've tried to play with the settings in /sys/bus/usb/devices/.../power/. To my knownledge the default settings are set to never suspend, and the dmesg doesn't say anything about suspending any drives (should it?), so I doubt this is the case. And also, I can still hear that the drive is on.
I have tried changing the USB cable but I got the same error.
So I figure, it's either a hardware problem (the USB drive adapter is bad) or it's the kernel -- I've read through some mailing lists that older kernels had some problems with USB devices disconnecting.
What I would like to try is to disable ehci_hcd and try to use a different module, though I need a little help with what module and how I would go about doing this. (I see in the lspci a reference to uhci, maybe try that?).
Anyone has any other ideas I can try that would also be greatly appreciated.
Thanks in advance.

I think I may have fixed it, or rather; it has worked the last 8 hours which is twice as long as the longest it did before.
Through ubuntu's bug tracker I found out that there appears to be a bug in the kernel (#32432). From what I read on the bugzilla, that bug appears to be only for 2.6.27-2.6.38 (is it??) and I was using 2.6.39 so I was really unsure if that bug applied to my kernel.
Nevertheless I built my own kernel with the help of abs. I used linux version 2.6.38, the standard arch linux patch for 2.6.38 and the patch located here.

Upgrade Options for Internal Hard Drive on dv2000t Laptop (Installation Problems)

I need to replace a failed hard drive in my 2006 dv2000t laptop. The drive I'm replacing was already a replacement drive from the original 80GB drive that shipped with laptop. That first replacement 3 years ago (2008) was a 200GB drive, that worked well for about 3 years. But it just crashed (apparently). I was getting some "S.M.A.R.T" imminent drive failure warnings a week prior, and then it finally would no longer boot-up. Subsequent tests on the extracted drive show it as having many failed sectors.
I had no problem ordering a replacement drive the first time in 2008, restoring an Acronis backup image of original drive, installing it, etc. All went smoothly in 2008. So I assumed all would go smoothly again for yet another replacement and upgrade.
In 2008 the drive I ordered was a W.D. (Western Digital, sticking with the same brand as original) 2.5-in 5400rpm SATA drive (200GB). That was a SATA (I) drive (1.5 Gbit/s interface).
The first drive I recently ordered (Mar 2011) was a W.D 2.5-in 7200rpm 500GB SATA II (3.0 Gbits/s interface) drive (from W.D.'s "Scorpio Black" line.) Got the drive, burned the disc image to it, and popped it into the laptop. Unfortunately, upon startup, and after BIOS screen, all I get is a black screen with a fast flashing white cursor at the top of the screen. Drive apparently is not being recognized by the computer? Then I did some reading in a few on-line forums and found some references about this laptop not doing well with drive capacities over 320GB, nor with 7200rpm drives (because they run hotter than 5400 drives). And finally, references to the SATA interface speed. I ordered a 2nd drive, this one from W.D's "Scorpio Blue" line, this time a 5400rpm 320GB drive (but still SATA II). Same story, still won't work. So I decided that maybe the issue was the SATA speed. So I found someone who still had an older SATA (1.5 GBit/s) W.D. drive in stock . It's a W.D. SATA 250GB (no longer made). It should arrive in a couple days -- and I'm hoping this one works!
I would like to get some kind of confirmation about the blinking white cursor on the black screen on start-up. Is that typicalif the system not finding a bootable hard drive? Also, is this SATA vs. SATA-II issue a likely cause of my problem? I'm pretty sure there's nothing wrong with the new drives themselves, and the restored images on them , as the drives will mount and are accessible when I plug them in as external drives on my other computer.
This question was solved.
View Solution.

I have been able to solve my own hard drive installation problems. It turns out that there were no issues with any of the new replacement drive(s) I ordered (thinking I had ordered drives with the wrong specs). The solution to the problem was a simple one. The restored drives were not booting because there was no MBR (Master Boot Record) on the drives after disc image restoration.
I am using Acronis True Image Home 2011 as my disc imaging (backup) software. And I just didn't understand how to properly restore backed up images to a new hard drive. I had done everything correctly except that I had not checked the box to "restore MBR" -- at the time not understanding what that was or its significance. Once I checked that box, and reimaged the new drive, it worked fine.

Trying to Bootcamp, Hard Drive Won't Partition

Hello there,
I am trying to use the bootcamp assistant utility to install windows 7 on a Late 2009 iMac. I got the Microsoft support software downloaded to an external Flash Drive using the Bootcamp utility and have a full Windows 7 Home Premium install disc that I have been trying to use, brand new bought yesterday. The problem is that I can't seem to get past the point in the Bootcamp utility where it makes the partitions for me. I receive this message:
"you disk cannot be partitioned. an error occurred while partitioning the disk."
I tried using the disk utility (as suggested online) to look at the hard drive and received this message due to an "invalid directory count":
"this disk needs to be repaired using the Recovery HD. Restart your computer, holing down the command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk utility."
I've done that but for some reason the Disk Utility there says that everything is okay after being checked and verified. I even chose the repair option to no avail.
I then went back online and was routed to trying to reboot my iMac using the Single-User Mode (command S at reboot). I used the command line:
"/sbin/fsck -fy" (no quotes) [enter]
the system ran the command; it checks and repairs inconsistencies in file systems that may prevent you from partitioning the drive. the result was
"**the volume macintosh HD could not be repaired.****the volume was modified.****"
i can post a pic of the set of command lines and results if needed, but the hard drive has never been modified. I need help figuring out how to solve this partitioning/hard drive issue.
Thanks

well I believe it always starts in safe mode; i'm not sure but it always starts up with the progress bar loading.
my situation has changed, I tried repeating my steps as aforementioned and have gotten the partitioning process to work but now upon startup the screen is black and says there is no bootable device, I can access my apple side of the machine restarting and using the "option" key and see that it is the only bootable drive. I think the reason for this is because I'm trying to boot Windows 7 using an external superdrive as the disk drive inside the iMac itself is unable to work. I don't know for sure if this is an appropriate solution, but I was wondering if there is a way to get the iMac to recognize the external usb superdrive as its internal optical drive.

Replaced dying hard drive, can't boot into installer

Well, this is always fun.
My hard drive was dieing in my 12-inch Powerbook (last-model, I believe), so I ordered a bigger one and just finished installing it.
So, I try to boot to my 10.5 installer disk, and it gets to the Apple logo for about a minute, occasional DVD drive noise, and then freezes. Even the little spinny thing stops spinning. Sometimes there are vertical, dotted lines running through the darker areas, sometimes not.
It was doing this when my previous hard drive was dieing, and that was on 10.4. I can now and could then log into single-user mode, but no GUI. I've tried everything I can think of, and nothing's worked thus far.
Any help? My laptop is completely dead without an OS, and I've got school work and a programming internship that largely rely on my laptop.

sheez
I'm really ashamed of these forums. Doesn't anyone here even know how to ask intelligent questions?
I managed to rip apart some of the info from the Single User mode, purchased a new set of OS disks, ran the hardware test, and discovered the video RAM had failed the test.
ANY of those should have been suggested by someone with some repair knowledge. Non-booting? Did you ask about the hardware test built into the OS disks? Noooo, I had to find that out , and run it, myself. Problem not solved by replacing hard drive? Gee...
Strange vertical lines on a boot screen where there shouldn't be any? Mayhaps it's video related? Hmmm? Even if you were wrong, it'd have been SOMETHING to try, instead of silence.
Maybe I should just amble around here and show you people how to help people. I've had almost NO help (often no replies, either) for most of my questions on this forum, despite offering more information than most, and I ultimately have solved most of them myself, when they didn't resolve themselves.

My hard drive went bad and I lost a lot of purchased items from the iTunes store. I want to re-download them but can not. They still show up on my purchased items. How do I solve this?

Update to iTunes 10.3.1
After you have finished, you can re download your iTunes purchases without having to re purchase.
iTunes 10.3.1
" Download Previous Purchases. Download your past music purchases again at no additional cost. Your purchases are available in the iTunes Store on your Mac or in the iTunes app on your iPhone, iPad, or iPod touch. Previous purchases may be unavailable if they are no longer on the iTunes Store."
"Available on iTunes in the U.S. and Canada only. Title availability is subject to change."

My hard drive has 70.93 GB available, yet when i have more than one internet tab open, i have to force quit google chrome because 'there is no more available application memory'. How can I solve this? I have a 2009 macbook pro running on 10.6.8.

My hard drive has 70.93 GB available, yet when i have more than one internet tab open, i have to force quit google chrome because 'there is no more available application memory'. How can I solve this? I have a 2009 macbook pro running on 10.6.8. I have tried updating to mavericks through the mac app store but after it downloading for a day i got an error message saying there was a problem with the download. The same thing happens if i try to update itunes or the mac app store. After research, i have also tried repairing disk permissions, but every time they do get repaired the 'repair' button still appears, i'm not sure if it's because it was unable to repair the initial problems or if it just keeps detecting new ones.

2 GBs is a minimum in which you can do many things, but not concurrently. Be very careful to not install third-party add-ons, limit the number of applications you choose to enter in Login Items, run as few applications concurrently as you demand.
I would consider adding more RAM to your computer. Your model supports 8 GBs, so I would install that.

My external hard drive will no longer connect to my macpro......any ideas on how to solve this problem??

My external hard drive will no longer connect to my macbook pro via FW800........Any ideas on how to solve this??

Reset the SMC, see this Apple note: http://support.apple.com/kb/HT3964
Also reset the PRAM:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
In most cases, those two actions will fix the port issue. If it's still an issue, you may need to see if the external hard drive can connect to another system, to ensure it's not having problems.

Not solved with Blinking Folder with Question Mark after Erasing Hard Drive

in response to Niel
Thanks for the reply, held command+R again and it is trying to pick up WiFi, but it's not picking up my network and won't accept the password even when I try to put it in manually. Any thoughts on that?
Me too had tried the command+R and failed to manually connect to my network. Can anyone help?

Well, it was solved. I shifted to other place and tried other WIFis. One of the WiFi had the 2002f problem and another was fine, so the reinstall worked smoothly eventually.
On the apple support page it says that Supported network configurations and protocols includs both WPA/WPA2, not matter what they are, but it might not be true.

[solved] LVM extend over multiple hard drives

I have a 500GB hard drive with several LVM logical volumes on it.
A couple of these partitions are getting full and I want to know if I bought another hard drive can I extend a partition across from one hard drive to another?
I hope that makes sense.
edit:
Even if that's not possible, I suppose I can just move the whole partition over to the new hard drive and extend one of the other volumes on the old one to fill up the rest of the space.
edit again:
Sorry I just answered my own question.
