Re: unusable space

This is anomaly of nomenclature. A megabyte for example, is thought of and in printed description such as this as 1000 bytes It is in fact 1024 bytes- do the sum you have exactly the right number of byres.

I just bought Lacie rikiki hard drives. As I put it into my computer the assistant starts. Unfortunatelly after few minutes the process stopped and the capacity is 465 GB instead of 500 GB. Is there any...


This is normal. You will never get all the capacity for a USB key or a hard drive. The missing space is for format purpose and hard drive maintenance.

Hope it helps

Hi, I bought the little disk (500 gb) and took it to a friend en he has a mac (i've windows) he punt some fileson teh disk after het installed it (for the first time) Now mij computer doesn't find the disk...

Mac uses diffirent file-system than windows.
Are the files on the disk important?
If not, you can do following (a complete formatting of the disk)
1. Press Win+R
2. Write diskmgmt.msc and press enter
3. Select your removable disk (if you don't know the name of the disk select a removable drive thats capasity is almost 500gb
4. Right click the drive and select remove partition
5.when deleted Right click free space and select create a new partition.
6.follow the instructions and you're done.

Not enough space to back up?

sure..the back ups are compressed files, usually, and though it appears to be a small file, the external drive will allocate the space that it needs. Mac's won't put a file anywhere that there is not enough room. PC's will slice it and spread it around, of course.
I recommend you off load some of those backups to DVD's and keep them for a month or so.
Or get more disk space.

Help with MyBook 500 GB- it makes a clicking sound and does not appear on my MAC desktop.

You have a bad hard drive. The clicking is a giveaway that something is wrong. Replace the hard drive.
I hope you had backed up your data, otherwise it may be gone. It's very expensive to have data recovered from a bad drive.....hundreds, sometimes thousands of dollars.

Not enough disk space to copy

Scan the drive due to possibly virus managing your disk drive. Virus can easily access through USB hard drives. If not solve the problem, so its better to format.

221 GB Free on MyBook - Error states not enough space for backup

Is the drive formatted as FAT32?

If so, and your backup is more than 4GB, it will not be able to write the file to the drive.

Open a Command Prompt (Start | Run | CMD) and at the prompt type:
Where V: is the drive letter of your My Book.

That will convert it to NTFS and it will be able to handle files larger than 4GB.

Seagate drive partition

This is fairly straightforward using the Windows XP tools.

IMPORTANT, copy everything you want to keep from partition F otherwise it will be deleted. Drive G will not be affected.
  • Right click 'My Computer' >'Manage' then click disk Management.
  • Right click your drive F and 'Delete Partition'.
  • You now have 210GB unused space on the drive.
  • Right click the unused space and "Create Partition".
  • Specify the size of the new partition to your requirements or create more partitions until the free space runs out.
  • You can then right click and format the new partitions. 'Quick Format' is fine unless you have been experiencing disk problems.
To swap around drive letters in Disk Management:-
  • Right click the drives and 'change drive letters', to X, Y or Z or whatever
  • Now you can change the drive letters back to F, G, H or whatever order you want them in
I'm sure you get the idea, you just have to change the letters of the drives to unused letters to make a space in the sequence (not that any sequence really matters)

Good luck

My Book Premium

Suppose you're using MS Windows... Click right button on (I) drive then check out "Properties" of your drive. In "General" tab you should see "Used space:" and "Free space:" If in "Used space:" is something like "24 KB" then it looks like you lost your files :( Otherwise somehow may happen that your files became "hidden" or "system" files. In "Control Panel" open "Folder Options" in tab "View" check/uncheck properties of "Hidden files and folders" and "Hide protected operating system files(Recommended)" to see what is in your (I) drive. Anyway may be helpful some program which can recover accidentally deleted files. Try to google "recover files" for such program.
