WD external disk error
-
Yes, I did run the command with sudo, and I am the admin for my MAC.
-
sh-3.2# dd if=/dev/zero of=/dev/disk1 bs=512 count=2
dd: /dev/disk1: Permission denied -
Do you have access to a Windows machine? You could use diskpart and clean the drive to wipe it out.
-
@Nara I do have one. Let me check in that.
-
OS X side, Disk Utility is used for this: repartitioning, formatting, et al. Gets grumpy with NTFS, but not much a hassle when wiping.

I concur - if you're keeping it Mac side, NTFS is not the way to go.

Ah, that reminds me, OS X is read-only for NTFS. Should be fine to wipe with Disk Utility, but most other operations would fail (sudo or no).
Curious, have not tried this...could be worth a shot as a test—

@Nara Tried on Windows, same issue- Access Denied! May be its time to get rid of that, but can't believe that the HDD is visible on disk management on both windows & MAC but can't access that!
-
have you tried a utility like SpinRite yet?
-
@Dashrender Thanks. Haven't tried it yet. Let me check that as well.

Spinrite isn't free, but they do offer a money back guarantee.

Access denied? Were you running the command prompt with elevated rights?
-
Tried what exactly with windows?
my computer > E/F drive access?
yes that will get denied... should actually come up with a message about granting access unless its formatted with some other partition like reiser/etc
under windows you should be right clicking my computer and choosing manage then seeing the disk loaded...
Make sure you're looking at the right one... they load 2 disks... CD (WD Ware) + Open Storage
in the disk manager you'll see if it can read the partition format - if its ntfs / other - no matter what you'll be able to wipe the storage side via any OS but can't wipe the non-storage CD Side... not without a little firmware flash / using WDWare tools to turn it offI'm wondering if he's seeing the virtual CDRom that these load... and not the actual storage...

@BC I tried the Disk Management, Selected the 2TB WD HDD, it was not initialised. Tried to initialise the disk and got access denied error. I hope you read my initial posts, that I tried the same thing using Disk Utility on a MAC and dd command to clean the hard drive.
@nara Tried the diskpart as well but without success. I am actually checking Spinrite if that helps. Will let you know the results soon.
