I have a 1.6TB Seagate FreeAgent GoFlex and when I plugged it in my cousin's Windows 7 Home Premium, it says "G: is not accessible. Access is denied." The portable hard drive however works fine on my Windows XP.
Any solutions?
Answer
1.6TB drive?? it should be a 2TB or 1TB drive.
the problem might be with either windows XP or the slot that you are plugging the drive into.
1, XP issue. some versions of windows have a restriction on the size of drive they can use, this might be the problem as to why your 1TB/2TB drive does not work on the windows XP machine, if there has never been any updates installed or service pack, it might not work, you may have to install all the windows updates and service packs to get the system upto date and read larger drives.
2, USB slot issue, there could be an issue with the USB slot, make sure that there is no dust in the slot and that it works, you can check if it works by plugging another USB device into it (like a mouse) and see if it works.

movie files losing data on external hard drive?
Pritesh
So I got a bunch of HD movies (4-16GB) each), and 400+ episodes of a show (300-400mb each) on my external hard drive (500gb), the issue I'm having is that after I copy the files from my PC to the HDD, a couple of weeks, or sometimes straight away, the files would 'lose' certain data or pieces. As in when I play the movie, it would play but show signs of data loss (picture not displayed correctly etc), I know this because I have the exact files on my PC hard drive and they play just fine.
This doesn't happen to every file, only certain ones...
I simply don't know what it can be, the three things I can think of is that the HDD is fake (well, not literally, thinking the manufacturer is rubbish - its made by zynet) and thus the loss of data, or the disk has become scratched and damaged or plugging the HDD in the usb in and out damages the data.
Any helpful tips? Should I just get a reliable HDD like seagate? I'm thinking an external powered one with 2TB
Answer
It does seem like the external drive has some kind of subtle corruption somewhere. It might just be in the file system, or it might be on the platter surface itself -- hard to estimate.
You can, if you feel you need to, open up the enclosure (under appropriate safeguards, such as anti-static protection) and determine what brand of drive is inside. Some are better than others.
The other possibility is that the drive is fine, but the enclosure's circuitry (often a USB-to-SATA bridge) has firmware with a bug on it (or has been corrupted by excessive heat, etc.) or will otherwise introduce subtle losses or corruption into the transferred data.
What you ought to do is this:
Clear the drive off (e.g. make sure you have a backup copy of the contents, and then clear it off. For best results (to ensure it's not a problem with the file system) go into the disk management for your computer, and select the external drive, deleting all of the partitions there. Then re-create the partition, selecting a decent file system (e.g. NTFS is more robust than FAT), and re-formatting that partition using the non-quick format.
Then do a surface scan on the drive. For a 500GB drive it'll take a long while, but it will tell you whether there are any bad sectors on the drive's platters. Bad sectors would imply deteriorating condition and eventual failure, so in that case you'd need to replace it.
If the drive formats ok, and has no bad sectors, try putting data back onto it, and then monitor it for any signs of data loss as you mentioned above.
You can purchase your own enclosures and drives nowadays -- often at a reduced cost as compared to buying a bundled enclosure-and-drive. For example, I have a 2.5" (laptop) 320GB SATA drive (Western Digital -- I trust no other, really) inside a StarTech 2.5" SATA enclosure. It works great for day-to-day use, but if you have any computers that use an eSATA interface it might make more sense to get an enclosure that has that connector -- much faster. My reason for the laptop-sized external drive is this: No need for a power cable, thus it's more portable.
Also, if you do get a 2TB drive, do some research to see if your OS and your enclosure treat it nicely and can handle the full size of the drive. I've got a feeling that the RAID controller I've been using nowadays is subtly corrupting the far (empty) end of my hard drive (which is a RAID 1 pair of 2TB drives), and I'm not sure that the files will stick around indefinitely. The last time I moved files around the drive by defragmenting, something got corrupted very, very slightly.
