That very small portion of drive space is used by encryption system for automatic launching a virtual RAM-drive with a special program that serves and controls the access to the encrypted volume on the drive. Of course, the motherboard must support HDD with capacity greater than 2.19Tb to see and access all sectors for 2.5Tb, 3Tb, and bigger Hard Drives.Īgain, going back to those invisible for USB-connection sectors, let’s have a close look at those mysterious hidden sectors the existence of which can be revealed by connecting the encrypted drive directly to SATA port. On the other hand, same 3Tb HDD can be represented system as 5,860,466,688 sectors medium when system uses traditional 512-byte per sector format, and here is no discrepancy, because 732,558,336 * 8 = 5,860,466,688 where 8 = 4096/512.

Most modern software and hardware work and communicate with 4096-byte per sector supporting hard drives, and show you only 732,558,336 sectors for 3Tb hard drive. In fact, it depends on the way you software (Disk utility, disk viewer, Disk manager, OS type) and hardware (the physical sector size supported by a Hard Drive model, USB bridge type) deliver, interpret, or select the sector size. It should be noted though that you may see the different LBA numbers on your computer. LBA distribution on WD 3Tb encrypted drive If you remove the drive from the WD external box and connect directly (SATA-to-SATA) to computer motherboard, the number of sectors will be 5,860,533,168.Ĭomparing the amount of LBA=5,860,466,688 sectors that are visible and explicitly available for computer operating system through the My Book Essential USB-port with slightly different, bigger number of LBA equal to 5,860,533,168 in total for the internal bare hard drive connected directly to the SATA port on computer motherboard, you may ask - Why the LBA numbers are different?Īs you can see you can see the difference equal to 66,487, and those are sectors reserved explicitly for the drive encryption software.

Unlocked drive will show 5,860,466,688 sectors.

WD DRIVE UNLOCK CD MAC PASSWORD

This drive is encrypted, and asking a password when connected through the USB cable to the computer. There might be an internal Caviar Green line HDD, such as WD30EZRX. Where are WD SES files located on the drive?įor better explanation where SES files are located on the drive, let's have a close look at the example with 3Tb drive comes in WD My Book external hard drive.

WD DRIVE UNLOCK CD MAC FOR MAC

My Book for Mac with model numbers WDBAAG0030HCH, WDBAAG0020HCH, WDBAAG0010HCH, and WDBAAG6400ECH.My Book Essential Desktop with model numbers WDBACW0030HBK, WDBACW0020HBK, WDBACW0015HBK, and WDBACW0010HBK.Mostly-affected models by this issue are listed below and have PCB 4060-705059-001 REV.

This problem can be solved in the data recovery lab by safely extracting files from damaged drive and back it up to the new external drive. Yet, if you don't care about losing files that were previously written on the drive, you may try fixing the problem by re-formatting the drive, using Apple Disk Utility software that comes with the device.Īs a result of the drive failure, the application responsible for launching the virtual partition with programs, controlling the access to the main large partition of the external storage with user data is failed and you see such error. The affected WD SES software corruption is basically happened due to the internal physical damage of the device, and cannot be fixed by simple re-writing the damaged code. Cannot read from sector 0 of WD My Book 111A.
