20 Most Recent Hitachi Deskstar 7K250 80GB (hds722580vlat20) 80 GB Hard Drive - Page 6 Questions & Answers

Personally, I think you really lucked out that it worked after being dropped. Then to be able to use it for two (2) more years is very exceptional for Hitachi drives. If you can hold the drive in your hand while "trying" to boot up....you "might" be able to gently rock the drive (face/label up) side-to-side and get the PC to recognise & maybe even read it. Have a flash/thumb drive ready "if" you succeed in seeing and reading any data on this - chances are you'll only get this 1 last chance to get your info. Good Luck.

Find and open the application Disk Utility under Applications Click on the external drive and click Erase. If you would like the drive to be compatible with Mac only, choose any of the Mac OS options. If you would like the drive to be compatible with Mac and Windows, choose FAT32.

In the BIOS select the drive you want to boot from.

Open Start menu Click the right mouse button on Computer On the pop out menu click on Manage In the left hand menu click on Disk Manage Your drive should show here if it is plugged in. Delete all partitions Now create a partition, format it how you want.

1. Check your power lead make sure both ends are plugged in and switch on. 2. Replace Power lead 3. Rehouse the drive (This is not hard and there are a lot of youtube clips that can help you)

Go into computer CMOS and set the boot up order amongst peripherals.

If mouse is usb try another usb port or try it on another computer/laptop. You can also try the add hardware in the control panel to see if that works. If not, then your mouse is not compatible or no longer works.

Do other usb devices get picked up? What operating system are you running?

Hi, I presume that in the box where they came packed it says "Mac compatible" since every HD nowadays is. They are not recognized probably because you did not format them.Warning: The following instructions will ERASE ALL of the Disk's contents.Do the following:

1. Plug the Disk into the computer.
2. Open "Disk Utility" app in your Mac (it is a built-in app, already on your Mac).
3. Big disks like that may take several seconds to initiate, be sure to wait for it to pop up in "Disk Utility's" left device list.
4. Select the disk in the left panel (device list) and then, on the right, select "Partition" tab.
5. In "Volume Scheme" select 1 Partition (or the number of partitions you wish if you understand the concept of a partition).
6. In "Volume Information" give the name to your disk/partition and select it's format (If you're going to be switching the disk between Mac and Windows select MS-DOS (FAT), if only Mac choose Mac OS extended). Warning: MS-DOS is an old primitive filing system so you will not be able to have single files with more than 4 GB on the disk, like an HD Blue-Ray movie.
7. Select Apply, done.

If you couldn't see the disk in "Disk Utility" then your USB ports may not be fast enough, in this case you may have a cable with 2 USB ports that go in the computer and both connect simultaneously the disk to provide more speed. If you don't I can't help you more with the information i've got.Good luck.
