Toshiba jacks up 2.5-inch hard-drive speed: Tops 10K rpm

Think 2.5-inch spinning hard disk drives are slow compared with the solid-state variety? Not always, Toshiba seems to be saying with today's announcement of drives that top 10,000rpm.

Toshiba launched four 2.5-inch HDDs, ranging up to 900GB in capacity, that boast speeds of 10,500rpm.

That's faster than the 5,400rpm and 7,200rpm 2.5-inch HDDs typically found in laptops.

The internal transfer rate for Toshiba's AL13SEB900 family of HDDs is 286 MB/s (megabytes per second), a boost of approximately 32 percent over the previous generation of drives "due to improved liner recording density," according to Toshiba.

Though slower than the fastest solid-state drives on the market, that kind of transfer rate approaches some less-expensive SSDs in speed. … Read more

Lock down USB drives in Windows with USB Disk Manager

USB drives are convenient for storage and for transferring data to other computers. This convenience also makes them a great delivery system for malware.

USB Disk Manager is a small Windows program that can help you manage the permissions of USB drives. The portable app doesn't need to be installed and can be run from a folder on your hard drive or from a USB … Read more

HDD Health monitors S.M.A.R.T. data in many systems

PanteraSoft's HDD Health is a compact piece of freeware based on a good idea: monitoring your hard drives' S.M.A.R.T. data to alert you when temperatures get too high, disk space gets too low, or signs point to impending disk failure. HDD Health then issues pop-up, audible, or e-mail alerts in any combination you choose. But while the latest build claims compatibility with Windows 7, we found that HDD Health wouldn't display S.M.A.R.T. data in 64-bit Windows 7 installations, something other users have had issues with as well.

HDD Health is … Read more

What happens during permissions repair in OS X?

One of the commonly recommended maintenance routines in OS X for tackling system slowdowns and other performance problems or odd behavior is to run a "permissions fix" on the boot drive. This is done with Disk Utility, and because it will not hurt the system to perform it is often one of the first suggestions people offer for troubled systems.

Permissions in OS X are file and folder attributes that grant a specific user or group access rights to that file or folder. There are two types of permissions in OS X, the first being traditional UNIX permissions, … Read more

Apple reminds users of MobileMe closure

If you have been a subscriber to Apple's MobileMe service, there is little doubt you've missed news on Apple's transition to iCloud, but if you are still using the older MobileMe service, then Apple is issuing reminders to get your data off of the service before it shuts down.

While iCloud has been around for a while now as a replacement for Apple's less-than-stellar MobileMe services, you may have held off on the transition in order to keep using features like Web hosting and the iDisk online storage options. These and similar features are currently not … Read more

Disk Utility showing less available space than the Finder in OS X

There are several ways to display disk usage in OS X, with some of the more-common options being the Finder's status bar, or to get information on your hard disk in the Finder, or to use Apple's Disk Utility program. However, while these options will display the available disk space on the system, in OS X Lion you might see some differences between the numbers reported in these areas.

For example, on my Mac running OS X Lion there is currently 184.43GB of free space reported as being available on the disk if I get information on … Read more

Clear out the clutter

Tidy Up is tool that can help you reduce hard-drive clutter by identifying duplicate files on any mounted disk. This utility's multipane interface has a bit of a learning curve, despite its new "Basic Mode," and the app's comprehensive search criteria and system of smart and manual "baskets" may not be immediately intuitive to casual users.

Anyone who spends time getting familiar with Tidy Up and its three- step approach, however, will find that it's a powerful tool for identifying and dealing with duplicate files, whether you want to delete them, move them, … Read more
