Therefore, if that's the subject drive of this Topic, you must have a desktop computer.
Buffer To Host (Serial ATA) 3 Gb/s (Max)
= SATA II specs
"now i can not access the files on it. i can see the files in windows but it says i can not access them. i am running vista and the external had xp."
By the way, you cannot load - boot from - an existing 2000 and up Windows installation that's on any external drive because of Microsoft's defaults. You get the error "Inaccessible Boot Device" or similar. There is no fix.
If the XP installation had one or more users that were using a password, you will get "access denied" messages when you try to access the drive's contents.
The same thing happens in XP and 2000, if the data contents were NOT made by the same Windows installation you are booting.
You need to follow a procedure to "Take Ownership" of the folders and the files on the drive XP is on. Your user must have administrator rights . You probably need a Vista operating system DVD. That procedure essentially removes the user protection that causes the "access denied" messages.
I know how to do that for 2000 and XP, but not for Vista and Windows 7. Perhaps someone else knows how to do that.
"i tried using the external as an internal again but now the pc will not recognize."
The mboard's bios must recognize the drive.
If it doesn't....
Check your SATA data cables. The connector on each end should "latch" into the socket on the drive and on the mboard, or on the drive controller card - it should not move when you merely brush your hand against it near the socket - if it does, mere vibration can cause a poor connection of it - use another SATA data cable that does "latch", or tape the connector in place.
(There is a slight projection or bump on one side of the outside of the connector that "latches" it into the socket - it's easily broken off or damaged)
The same thing applies for the SATA power connection.
If the bios recognizes the drive, it will at least show up in Device Manager , and in Disk Management, in Vista.
If the bios recognizes the drive, it shows up in Device Manager and in Disk Management in Vista, but you can't see the contents of the drive in My Computer or Windows Explorer, that's probably because the data on the drive is damaged.
The most frequent reason people can no longer access the data on a USB flash drive, USB External drive, or a memory card that was in a computer's card reader slot or in a USB card reader, is they unplugged it while Windows was running WITHOUT clicking on the Safely Remove Hardware icon in their taskbar lower right, and choosing to STOP accessing the drive.
(If you get a message you can't do that, then stop accessing it elsewhere - e.g. in My Computer or Windows Explorer, or in whatever you were accessing it with, e.g. change the drive letter, then you will be able to STOP it in Safely Remove Hardware.)
The Safely Remove Hardware icon may be hidden - if so, you have to click on < at the left end of the icons in the taskbar to reveal it.
It's a gray rectangle with a green arrow on it in XP, 2000, and ME, (and in 98 and 98SE, only if you have third party flash drive etc. drivers installed, or you have connected an external drive.)
In Vista, and probably Windows 7, it's a medium green small circle with a white checkmark on it.
You can unplug the USB device at any time when Windows / the computer is NOT running. You can plug it in at any time.
If you did damage the data that way, you won't be able to access the data normally when you remove the drive and install it internally.
Try running a program that can the repair the data damage.
In most cases, you will then be able to access the data on the drive, no problem.
However, you may be able to then see the files and folders but still have the "access denied" problem, if the drive the files are on was NOT present when you installed Vista, or in any case.
Testdisk - get the Stable version:
PC Inspector (freeware)
Zero assumption Recovery
The demo is limited
It will only recover 'up to' four folders per run
But you can make multiple runs
Really good, but you have to pay for it.
