Seagate FreeAgent GoFlex for Mac Storage System FAQs

1. What is special about GoFlex™ for Mac family?
The FreeAgent® GoFlex™ for Mac storage family delivers an easy-to-use, plug-and-play external hard drive experience while offering the flexibility and upgradability that many people are now demanding due to the evolving nature of how mobile and active people’s lives are becoming. With different options of external drives, cables, desktop adapters, and edge devices, the entire family of GoFlex drives can be customized to fit your lifestyle needs – whether with your PC, on your TV, over your network, or on-the-go. GoFlex interface cables are about providing the speed, performance and connectivity that consumers are demanding today. With the explosive growth of video-on-demand, multimedia streaming and growing personal digital libraries, consumers are now moving multi-GB-sized files at a time. These trends are driving demand for high-capacity, high performance storage. USB 2.0 is still adequate for most people, but as more and more video content is stored and moved around, USB 3.0 will become more attractive for consumers. As the world’s most upgradable external drive, the GoFlex ultra-portable drive can be paired with any GoFlex upgrade cable to enhance the transfer speeds or can be used with a GoFlex device to gain access to your digital life from your TV or over your network.

In addition to offering the option of changing the speed and performance to move and read files more quickly, each GoFlex drive is part of the GoFlex Storage System, which allows it to work with any other product within a broader ecosystem. Products within the GoFlex Storage System include:

  • GoFlex™ ultra-portable drive (14.5mm and 23mm versions)
  • GoFlex™ Pro ultra-portable drive
  • GoFlex™ ultra-portable drive (drive-only version)
  • GoFlex™ Cable – USB 2.0
  • GoFlex™ Upgrade cable – USB 3.0
  • GoFlex™ Upgrade Kit – USB 3.0 kit
  • GoFlex™ Upgrade cable – FireWire® 800
  • GoFlex™ Upgrade cable – Auto Backup
  • GoFlex™ Intelligent dock
  • GoFlex™ TV HD media player
  • GoFlex™ Net media sharing device

2. Why is GoFlex for Mac unique?
Aside from the GoFlex eco system and the ability to take advantage of all the tools available from the Mac OS, the GoFlex for Mac drives can also be used interchangeably with PCs without reformatting the drive. Simply install the HFS+ driver, available for download, on the PC and use the drive on both platforms. There are no file size restrictions or performance hits.

3. Is GoFlex for Mac compatible w/ Time Machine?
Yes, all of the external hard drives in the GoFlex for Mac family are formatted to HFS+ out of the box, which is fully compatible with Time Machine software.

4. What is the difference between GoFlex for Mac and GoFlex Pro for Mac?
The GoFlex Pro for Mac features a faster 7200RPM drive. Since this drive has a faster spin speed, it takes further advantage of the faster FireWire 800 interface.

5. If the activity lights are distracting, can I turn the LEDs on/off?
Yes, via the downloadable program from Seagate’s support website. This program will also allow users to perform drive tests to assure the drive is working properly.

6. How is the GoFlex series of products different from other available external hard drive solutions?
The GoFlex family of drives is different from other standard hard drives available today in that it provides more than just a way to store, backup and protect your digital content. FreeAgent GoFlex drives deliver:

  • Flexibility: You can use one drive in many different ways within the GoFlex family, including on your computer, on your TV, over your network, or on-the-go.
  • Interoperability: Use the same drive on both Mac and PC interchangeably.
  • Upgradable: Use the included plug-and-play FireWire 800 or USB 2.0 interface now and have the option to upgrade to either USB 3.0 or powered eSATA (portables only) later.

7. Is USB 3.0 backward compatible with USB 2.0?
Yes, USB 3.0 is fully backwards compatible with USB 2.0. It is however limited to USB 2.0 speeds.

8. Can I interchange cables and adapters between GoFlex for Mac, GoFlex Pro for Mac and GoFlex Desk for Mac?
It is possible to interchange all cables and adapters between the portable solutions – GoFlex for Mac and GoFlex Pro for Mac – however, you cannot use a portable solution cable with the GoFlex Desk for Mac because the power requirements of the GoFlex Desk for Mac exceed what can be supplied through a USB, eSATA or FireWire port. Therefore it is necessary to use GoFlex Desk for Mac power adapters that are designed to draw power from a standard AC power outlet.

9. Can I plug any bare drive into Seagate’s GoFlex cables? Will they function properly?
While the GoFlex cables are capable of plugging directly into our Seagate Barracuda and Momentus drives and used with a laptop or desktop, we do not recommend or support their use with an exposed drive. The added benefit of the GoFlex solutions is to have a durable enclosure that allows for portability, use with other products in the ecosystem and delivers all the added physical protection you would want to keep your most precious data safe and secure.

10. What does upgradeable mean? Can I increase the capacity of my drive?
While it is not possible to increase the capacity of your GoFlex drive, the unique and seamless GoFlex cable system transforms the GoFlex and GoFlex Pro for Mac ultra-portable drives into truly upgradable solutions in that you can access the content on your drive with any interface you would like, all by simply selecting the cable that matches your interface of choice. Each GF for Mac drive comes standard with FireWire 800 and USB 2.0 adapters and cables for a complete out-of-the-box experience. However, by simply changing the cable, you can upgrade the speed and performance of your interface to faster powered eSATA (portable models only), or USB 3.0.

11. Why is there no power button on GoFlex Desk for Mac?
There is no need for an on/off button on the drive since the option to put the drive to sleep when not in use can be managed through the system preferences of the computer.

12. What are the model numbers of GoFlex accessories?
This table provides the various GoFlex accessory model numbers.

Family
Model Number
GoFlex Upgrade CableUSB 2.0 STAE100
GoFlex Upgrade Cable KitUSB 3.0 STAE101

GoFlex Desk Desktop AdapterFireWire 800/USB 2.0 STAE105
GoFlex Desk Desktop AdapterUSB 3.0 STAE106
GoFlex Desk Desktop Adapter KitUSB 3.0 STAE107

13. Can the USB 3.0 adapter be used with a Mac computer?
Yes, it will work in USB 2.0 mode. Mac computers do not currently offer USB 3.0 support. However, the USB 3.0 connector will work with a USB 2.0 port.

Note: The optional USB 3.0 PCI Express or PC Express cards will not work with Mac OS since a driver is not available.

14. Can the FreeAgent GoFlex Net be used with Mac OS?
Yes, the GoFlex Net works with 10.5 (Leopard) and 10.6 (Snow Leopard). There was an issue with Mac OS 10.6.3 when using the WFS (Windows File Sharing) feature, but an update to Mac OS 10.6.4 resolves that issue.

Microsoft Windows Me FAQs (Part II)

Windows Me Is there support for a “rollback” feature that guarantees a working system in case of Windows Me failure?
There is a feature in Windows Me called “System Restore” – this feature allows Windows Me to revert to an earlier “known working” configuration of the Windows Me installation if the current configuration becomes corrupted and makes Windows Me unbootable or unusable. For further information on this feature and how it is used, please contact Microsoft.

Will Windows Me still run my older 16-bit applications and DOS applications?
Microsoft has stated that Windows Me will have complete compatibility for older 16-bit applications that run in DOS, Windows 3.xx, and Windows 95/98.

Will this be the last Windows operating system based on DOS?
Microsoft has stated that Windows Me will indeed be the last operating system based on the 16-bit DOS code base.

How do I make a bootable floppy or bootable hard drive with Windows Millennium (WinMe)?
Right clicking on a drive (floppy or hard drive) in My Computer or Windows Explorer only allows for formatting, WinMe no longer offers an option to copy system files and make the drive bootable. Use the following procedures for making a drive bootable.

Floppy: Making a WinMe Startup Disk is the only way to make a bootable floppy with WinMe. The WinMe Startup Disk is made the same way as in Win95/98 (My Computer-Control Panel-Add/Remove Programs-Startup Disk Tab-Create Disk).

Hard Drive: Using the SETUP command contained on the Distribution CD is the only way to make a bootable hard drive with WinMe. Although the WinMe Startup Disk still includes the FORMAT and SYS commands, you will receive the following notices when trying to use FORMAT C: /S or SYS C: “Microsoft Windows no longer supports the FORMAT /s command” or “Cannot find the system files in the standard locations on drive c:. SYS can only be used on drive c: to attempt repair of an already existing installation of Windows. Use Windows SETUP (Distribution CD) to make drive c: bootable”.

Will my Windows 95/98 programs run under Windows Me?
Because Windows Me shares so many common features and inherent programming structure with Windows 95/98, most, if not all, programs and applications from the previous versions of Windows 95/98 will work under Windows Me. However, contacting your software vendors and/or Microsoft for software application compatibility before purchasing Windows Me is a good idea.

Will Windows Me be available to purchase in retail stores, or will it be available only pre-installed on new PCs?
Windows Me should become available in retail stores sometime during the late Spring or early Summer months of 2000. It is believed that during this same time, many retail PC manufacturers will begin offering Windows Me pre-installed on many computer systems.

iPhone Data Recovery

iphonedatarecovery 1. About iPhone Data Recovery

iPhones can suffer from glitches, which can result in the phone crashing and needing to be restored. When this occurs, the restore process will wipe the device clean of any data. Data can be restored, however, and the process is simple through iTunes.

Function
Each time the user syncs his iPhone with iTunes, the device will back up unless the backup process is interrupted.

Significance
The backup process will create a disk image of all personal data on the device. When a restored iPhone is connected, iTunes will ask if the user wants to restore using this disk image.

Features
The following data will be backed up and ready to restore in the event of a crash: contacts, settings, applications, text messages, email messages, recent and missed call lists, any mobile Safari favorites, notes saved, set alarm and most preferences.

Misconceptions
Unlike failures in other phones, the iPhone’s syncing process (and the regular backup) prevents the loss of data.

Prevention/Solution
Prevent the need to restore by only installing applications through the App Store. Unauthorized applications through other means can cause the phone to fail or need to be restored in some cases.

Warning
Never interrupt the backup process. You never know when you may need the backup you just interrupted.

2. How to Recover iPhone Data

If you lose the data on your iPhone, all is not lost. Thanks to some free programs and Apple, there is a good chance you can recover your data. These steps walk you through the process.

  1. Refrain from copying more files onto your iPhone when you think you have lost files. You need to run a scan to see whether your files are still there so you can recover them.
  2. Download a program that is capable of searching the files on the hard drive of your iPhone. These programs are available for free on the Internet. Once such program is recover4All Pro.
  3. Allow the program to run so that it can scan and recover all of your files. This can take up to 3 hours because it scans the entire hard drive of the iPhone.
  4. Connect your iPhone to the computer you usually use to sync them if the above method does not work.
  5. Hit the Summery tab in iTunes, and click Restore.
  6. Select, when requested, the option that offers to restore your previous settings. Because your files will be backed up on your computer, your data should be restored.
