Partition Failed With The Error Unable To Write To The Last Block Of The Device

solution for me.My hard disk suddenly disappeared from desktop after nine to ten months of usage. Managed to mount unable to write to the last block of the device mac it eventually but Finder said that I have limited access to it and asked me to backup whatever I can. I didn't have any data loss because I backup regular to other hard

Disk Erase Failed Unable To Write To The Last Block Of The Device

disks.Tried DiskWarrior 4.1 to see if it helps and DW reported some errors and stopped operation. Anyhow, I tried to repair, erase or partition the hard disk in question but Disk Utility said either resource busy in Leopard or input/output error in Tiger when I used separate startup disks.Finally, I ran TechTool Pro 4.5.6 and did some scans. Read/Write scan passed but when it came to disk erase failed couldn't open disk Surface Scan, it spilt out lots and lots and lots of bad blocks.So, can I assume that the hard disk is a goner or is there any chance to erase the hard disk and use it as a temp storage? I have two more hard disks suffered the same exact faith. All three hard disks are of the same batch. Wonder why this happen?

This procedure will write zeros to all sectors. The drive will attempt to map out any bad sectors. If there are too many, the procedure will fail with an error message, or it will stall and never complete. But if it does complete successfully, you may be able to use the drive, at least temporarily.I have two more hard disks suffered the same exac

Once I try running the i command, I get an error message saying that the resource is busy: pdisk: can't open file '/dev/rdisk1' for writing (Resource busy) I get the same result when using /dev/disk1, /dev/rdisk2, and /dev/disk2.

I would assume it is the combined HDD and SSD of the iMac. /dev/disk4 - An external hard drive. /dev/disk5 - I have no clue what this is either. Maybe utilities for /dev/disk4? The iMac has a fusion drive, and /dev/disk1 is the HDD. I've tried with the SSD, /dev/disk2, but I get the same result. I have the iMac plugged into another computer via thunderbolt, and by holding t when the iMac started up, the Macintosh HD showed up as an external device on the other computer. How could I get rid of this message?

10.5: Avoid 'resource busy' errors in Disk Utility Nov 08, '07 04:30:00PM • Contributed by: Roph In attempting to use Disk Utility to make a .dmg image file archive of a volume http://hints.macworld.com/article.php?story=20071029100721107 on my Mac under Leopard, I got a new error message that did not appear before with Tiger: Unable to create "Drive To Backup" (Resource busy). Apparently in Leopard, you have to first unmount the volume you want to back up before you attempt to backup the image from the File » New » Disk Image From menu selection. [robg adds: A commenter on the queue review disk erase site notes he had the same problem, but believes it to be a bug (which he filed).

When I got the "resource busy" error, I tried using Disk Utility's "Unmount" button before trying to create the disk image, but this doesn't work because DU no longer sees the drive (didn't it use to have a "Rescan" command to find drives that weren't mounted?) I unplugged and replugged the FireWire cable so Disk Utility would rediscover the drive, then in the Finder, dragged the drive icon to the trash. Only then was I able to create the disk image. Poor design! [ Reply to This | # ] 10.5: Avoid 'resource busy' errors in Disk Utility Authored by: lexicon5 on Jul 15, '09 06:35:56AM Works perfectly well...and this issue is still present in 10.5.7. Unmounting the partition as opposed to ejecting the disk is what's required. Scratching head. Can't figure out why Apple would red
