Question about Seagate Computers & Internet

2 Answers

My Seagate harddrive is recognized by my basic levels, BIOS and CMOS, but is not assigned a letter in Windows. Also, I cannot mount and browse in DOS. When I run SeaTools, again, the drive is recognized (serial no., drive size, etc). After running the diags, error code A99FDC5E is displayed and notes that there may be damaged sectors. I have actually purchased a donor drive for head and/or platter replacement - however, I have never actually performed either. Any help would be greatly appreciated. Thank you in advance.

    I believe that I have the general technical know-how to complete a platter repair. Can someone please tell me what this error code implies is the problem? Is this the platters or the heads or something else?

    I'm not looking for a long-term fix, just long enough to save one file... can anyone give me some guidance based on my comments?

  • Luke Aug 01, 2010

    I need to recover some data from this drive. Only one file first, then thousands if it can handle it.
    You should also be aware that I have connected this drive to several other computers, including trying a SATA external adapter. Windows will beep as though it recognizes that I've plugged the drive in, but it does not show up in my storage management or My Computer areas. And, when I use the external adapter, I get a "click and beep of death" whereas when I attach directly to the motherboard, it sounds relatively normal - although I can hear the heads repeating the same pattern over and over.
    Are you suggesting a format to fix the bad sectors? Then, using a data recovery software tool to recover my files?
    Like I've said, I have a donor drive that I'm prepared to use if I need to.
    What would you do?

    I'm ok, you? I just can't get a definitive answer as to whether it would even be beneficial to attempt a platter or head replacement on this drive. Have you any other thoughts?

    Well if Im in the situation I'll reformat the drive then use a file recovery program to retrieve the files. Its the only choice we got since the drive is busted that only a reformat can resolve.

Hello there Luke,

Here is what you do:

1. Right Click your My Computer or Computer and choose Manage.
2. It will open you the Computer Management window.
3. Click on the Disk Management and wait until it shows you the list of disk drives on the right side.
4. When you see your Seagate harddrive, right click to its partition (the white area) and choose change drive letters and paths.
5. Follow the steps and assign a drive letter you want.
6. After applying changes, you will now see the drive letter for the Seagate on your windows explorer.

Should you have any questions, please let me know.

    No, this is a problem with a damaged drive. I tried what you recommended a long time ago. I'm at the point now where I may attempt platter and/or head transfer. Do you have any idea what the Error Code stands for: A99FDC5E. Is is head or sectors, etc?

I have a Seagate Barracuda 7200.8 200 gig The drive spins up but is not detected in bios. I have replaced the cable and the drive, my pc is up again. The Seagate drive acts as though it has a firmware...


Install the Western Digital OS drive as a master with a slave present and the Seagate drive with no jumpers set as a salve. Turn on the computer and immediately press the Delete key or press it when prompted to enter the set up bios. The first screen is the Main BIOS Setup Menu. Do see you Seagate IDE secondary slave since. If none is displayed on the secondary slave highlight none in the secondary slave column and press enter. Press enter to auto detect the drive. If no drive is detected, enter the drive capacity, cylinder, and head manually. Make sure the PIO and UDMA are both set to auto. If the above results in no change you may try loading fail-safe defaults from the exit menu and save and exit. Start windows normally. If you do not see the drive click on start and select run. Type compmgmt.msc in the Open: pull down selection and click OK. Click on disk management and look for the Seagate drive. If you see it right click on the drive icon and make it basic. Make sure you see an assigned drive letter or right click on it and assign it a drive letter. The last task is to download and install Seatools and use the utility to try to repair the drive from the below link.

Download and install Diskwizard and see if it will recognize the drive for a new install.
I sounds like you drive is defective on the interface which will require service.
You may have tried the above but if none of the above has any positive results the drive is defective.

Seagate portable drive not recognizes no letter


jedtrisha

Alot of times when the drive letter is not assigned this means that another device is already assigned to the drive letter that the drive wants to take.

The below link will take you through changing your drive letter on your Maxtor drive.

http://www.fixya.com/support/r4176803-change_drive_letter_in_windows_vista

Note if you have Windows XP let me know and I can give you the change in the steps if you have trouble but they are almost the same.

Let me know if you have any more problems or questions.

Seagate barracuda external 500 gb hard drive usb not seen any longer,cables and power okay , tried on three computers


Verify what Drives have been detected by your Operating System by using Windows: Control Panel -> Admistrative Tools -> Computer Management -> Disk Management -> Your Hard disk(s) will be displayed with all existing partitions and any assigned drive letters.
Your external (or internal) drive must be recognized as having formatted partitions that have a drive letter assigned to each required partition.
Hope it helps: let me know how you go!

I want the bios recognise usb flash


Start Windows.
Insert the USB flash-memory device.
Windows should recognize the device, and assign a "drive-letter", such as 'E:' or 'F:'.
Open "My Computer".
Select the 'E:' or 'F:' drive, and browse the files/folders.

Maxtor 500g harddrive wont come up on my pc wen i plug it in how?


First, check to see if it registers in the BIOS. Since you plugged it in yourself I'm assuming you know how to check, but let me know if I'm wrong. If it doesn't register in the BIOS, it's either not connected properly or the drive is broken. Play with the cables and with the Master/Slave pins and see if you can get it to register that way.

If it does register in the BIOS but just doesn't have a drive letter in Windows, you could try to assign it one through the Computer Management console. From your Desktop, right-click the My Computer icon and select Manage. Under "Storage", select "Disk Management". If you see a drive there that has no letter assigned, you can right-click and mount it.

Replaced harddrive and dvdroom wont recognize in bios


Goto bios menu. And change the setting on hard drive and cdrom. It could be it still set in the old configuration. Try to set it in auto detect. Then save the setting. Then goto bios once again to check if the settings doesn't change. Restart again and wait if something you didn't expect still happens.

Leave a comment if this solve cd rom detection.

Comp won't assign drive letter to recently added Seagate ST310211


Its possible the drive doesnt have a partition on it. Right-Click on "My Computer" and go to "Manage". Then go into Disc Management and the drive should show up.

If you see the drive, you can create a partition, and assign a drive letter :)

I want to use my seagate freeagent with our server windows 2003. how can i do it. if i plug it, windows says usb device not recognized.


As administrator:
Click Start->Right click My Computer and choose 'Manage'
The Computer Management window will open.
Click on Disk Management and you should see the rive listed in the right-hand pane, without a drive letter assigned.
Right click on this drive and assign it a letter, like Q.
You'll now see drive Q (or whatever letter you picked) in the regular drive list.

It recognizes the new hard drive as a DVD drive


have you partitioned and formated it ? unless you do that to the drive it will not show up with a drive letter in windows. go into control panel, administrive tools, computer management, disk management - there you should see all your drives and you can partiton, format, assign or reassign drive letters to them. hope this solves your problem.
