I'm using Windows 7 and trying to use its backup and restore utility to backup my C: drive to my 3TB Seagate GoFlex Desk external HD but I get the following error: 0x8078002A

Its because your backing up to a 3TB HDD.

Windows 7 has a really had time backing up to anything over 1TB.

You can force it to go but it may not be stable or it may just keep failing.

It should be noted that anything over 1TB can have problems.

What are my options? It's the only drive I have for backup/storage and I have 1.28TB of data stored on it currently.

New drive or upgrade to W8 (since I've read this issue has been addressed in W8)?

Wouldn't it be better to find something from Seagate? I don't want to mess anything up running apps that aren't made by and for Seagate...

Ok, I will look into it when I'm done backing up my drive's data. I'll keep you posted.

Go to Start/Search and type diskmgmt.msc right click the diskmgmt icon in the results and Run As Administrator. In the Elevated Disk Management window, You can right click the volume/partition in the external and Shrink Volume to 1TB or under. Right click the Unallocated Space and create a new simple volume (partition) and then backup to that partition.

Unless I misunderstood, you want me to partition my 3TB drive by making a separate 1TB or lesser partition to backup my C: drive to?

If I do that, it would be fine for me considering my internal C: has a 1TB capacity so the weekly backups would never exceeds the allotted capacity in that partition. But my concern is that when using W7's backup utility, it only gives me the option to select a drive location for the backup, it doesn't go as far as giving me the ability to select the partition on said drive (and I really want to use W7's backup utility for personal reasons).

Unless you can find a way to instruct me on how to specify the partition to backup to, I think formatting the entire HD would be the best option.

Also, regardless of how I decided to do this, I need to backup 1.28TB of storage that's on my external drive. I don't know where to put it. My second external HD is 500Gb and my internal C: only has 814GB remaining.

Another question. If I decide to keep using my 3TB drive for storage and just buy a new 2TB internal HD, would that new hardware require me to reconsider my PSU? I've been continuously adding up-to-date hardware to this old PC but haven't considered whether it can handle it. I have a 500 watt PSU.

Also, considering the internal drive my OS is running off of is 1TB, and the internal drive that I'll be purchasing will be for backup purposes, would it be sufficient to get a 1TB internal for backup or would you advise me to get 2TB?

Is this good? Newegg.ca - Western Digital WD Blue WD10EZEX 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive - SSD/ HDD Accessory

The USB HDD is currently Drive G: on the External Hard Disk. When it is partitioned, the new partition takes on the next available Drive letter (eg) Drive H: you would be backing up to the H: Drive, even though it is on the same Hard Disk as the G: drive. They are on the same Disk but separate Drives.
If you are just going to be using the backup drive for storage and backups, and not installing an OS on it, you can go as large as you can afford.

What would be the maximum I can partition the H: drive to considering Windows 7 has a hard time backing up to certain sizes of drives...

Just because Windows says you have 1.28TB of files doesn't mean all of that will get backed up. In fact Windows backup won't even backup Windows itself. All it will do is backup important files.

Windows should be able to backup to a 1TB no problem.

You really shouldn't buy anything over 1TB as they will have problems.

Have you already filled your 1TB HDD?

You misunderstood. There is 1.28TB of data stored on the external HD. I do not have any backups at the moment, just storage. If I need to format that 3TB external HD or partition it, I would still need to temporarily back up that 1.28 TB of data meanwhile I do so but I don't have anywhere nearly as big enough to back that data up to.

Windows should be able to backup to a 1TB no problem.
I know that Windows doesn't backup everything. I will get a 1TB drive instead of a 2TB internal in that case.

No. It's a 1TB internal and has 814GB free.

We are glad you got it sorted. You do not have to Format your 3TB drive to partition it. Though it is always a good idea to have your files backed up before messing with the drive. The instructions for creating a partition without loosing data are at post #8

OK and just to make sure for future references, when you partition a disk into separate drives, Windows assigns them separate drive letters right? So they appear to be different disks but in reality they are not...

And what are the benefits of partitioning drives, other than what I'd use it for.. just curious.

In the old days, people would partition a drive and install the OS to one partition and use the other partition for storage. If the OS took a dump, you could reinstall and not loose the data on the other partition. However, if the HDD failed you would loose everything. Now that drives are relatively cheap these days, this is not necessary to do, as you can just get a separate HDD for storage.
As stated, if you partition your external 3TB HDD into 2, it will have 2 different drive letters and be 2 individual independent drives.

Is that why some people prefer using SSDs for their OS and HDDs for their data?
