HP700ux UDO library

[Patrick_129]

Hi guys,

Recently, i installed a HP700ux UDO library and did a formatting on a UDO media.
The formatting took about a total of 5.2hr (2.8hr on each side).
Is this formatting speed normal? is that any way to shorter the formatting time?

Thanks
patrick

Patrick,

This is not an unusual amount of time for a full re-format. The media is delivered from the factory with this type of low-level format. This low-level format is ready to have a file system added. Writing a file system to the disk surface should only require a few minutes, but a full re-format is different. This causes the disk surface to be written with a format pattern to all 1834348 Logical Block Address's (LBA's) on the disk. Next, each LBA is verified and then each LBA is erased.

Many times (like in windows) a new file system is referred to as a format. Sometimes, the driver will use a term like "quick format" to mean that only a new file system will be written. I hope this has helped you. Thanks.

Hi,

Ok, I found out that quick formatting took 45mins.

Question, any idea if UDO media is already pre-formatted?

Thanks!

Yes, as Tom said it's low level formatted. You just need to add whatever file system or directory structure is needed by your app.
