Case:Some client’s Seagate 500GB hard disk cannot be opened or copied, and some folders are empty. Solution:After receiving the hard disk for the data recovery center, the engineer took about ten minutes to test time, confirming that the hard disk was defective, and a small amount of physical bad ducts appeared, which caused some data…
Software: Getway Raid Recovery 2.0;
RAID Type: RAID 5 with 3 drives, 1 drive defect;
Factory Type: IBM
Malfunction Description: Sudden RAID damaged, all in the state of “DDD”, RAID corrupted by replacing the hard disk order off-line or push-pull, all the files lost.
Select the “Smart Mode”, and then click the “Next” button.
(Once you get a RAID recovery case, we usually suggest you firstly select “Smart Mode“, It is the most convenient and efficient Mode: Fast, Intelligent. Certainly, if you clearly know the RAID details, you can recover the data by directly using either the Manual Mode or User-defined Mode.)
The default set is Factory Type as “Standard” and the Raid Type as ” Raid 5″ (you can select the right Factor Type and the Raid Type according to your RAID Array), and then click the “Next” button to rebuild and recover the RAID Array.
A) Analyze:
Click the “Analyze” button after your finish the parameter setup. Getway RAID Recovery software will display the parameters and the right disk order of your RAID Array, and also you can view the reconstructed partition information.
B) File View:
Select one partition and click “File View” button, a file browser will be popped up. You can view the folders and the files from the browser after successfully analyze. You will know the analysis was successful or not by this step.
C) Export Image:
After you verify the authenticity of the data, and also you sure you want to get the data back, you can purchase a License Key and activate the software. The detailed operations are as follow: after you get the License key, please click the “About” button and input the ID and License Key to activate the software.
Then you can export the partition as the image files or export the image to other hard disk.
Attention: Please don’t export the image to your system disk, otherwise it will cover the data which on your system disk.
Rebuild RAID:
Verify the authenticity of the image files, and then reload the image files to the new RAID Array. RAID Recovery is successful.
Here’s my problem I’m trying to do a cleanup of my hard drive, and I’m constantly seeing this scenario: (1) Aggregate folder size: I check the folder size viewing properties right clicking the folder (2) Individual folder/file sizes: I check the individual file/folder sizes belonging to that folder viewing properties on the individual file/folder sizes,…
I did a dumb thing and now need to undelete some files. In fact, I have already recovered the files using Glary Undelete, which has served me well on the other rare occasions where this has been necessary. So I have the files. The problem is that Glary and the other undelete options I’ve…
We first look at the following two pictures. Picture 1 is the “BIOS CHIP” of the circuit board. When we replace the PCB, we need to swap the “BIOS CHIP” with your original PCB. Picture 2 shows the “Board Number” of the board, and the “Board Number” must be the same! FAQs of 100815595 PCB…

DOS and DOS based programs like Windows 3.x and Windows 95 cannot access drives over 1024 cylinders on their own, but require third party assistance to use large hard drives. SCSI drives handle this with drivers built in to the SCSI controller, so we will limit this discussion to ATA hard drives. There are several methods used to overcome the cylinder limitation, and all of them involve translation.
A translation scheme converts information from one form to another and back again. Think of it like this: If you go to a foreign country to conduct business and you don’t speak the language, you need a translator. The translator’s job is to convert information from one party into a language the other party can understand and vice versa. Without the services of a translator, the two parties have a limited exchange of information. A smile, a nod, and a mispronounced and grammatically incorrect “How are you?” is about all that is possible.
The types of translation support are as follows:
1. An ATA (IDE) host adapter with a BIOS that provides large drive support.
2. Third party software like EZ-Drive® and DiscWizard Starter Edition.
3. A motherboard BIOS that provides large drive support. Some of the terminology is as follows:
These support features are the “language” translators that allow your operating system and hardware to speak two different “languages” and still interact successfully with one another.
All of the BIOS options, once installed, are transparent to the user. EZ-Drive and DiscWizard Starter Edition are not. In addition, there is one issue that both share — special procedures are needed to boot to a diskette when installing new software.
Dynamic Drive Overlay software like EZ-Drive and DiscWizard Starter Edition use similar techniques, at first glance, to overcome the 1024 cylinder limitation. Both programs load proprietary translation information on the boot hard drive that identifies which drive is using the program and gives the operating system access to the area of the drive over 1024 cylinders. Without this proprietary translation code loaded, the drive using EZ-Drive or DiscWizard Starter Edition is unrecognizable to the operating system. If the hard drive is using translating software, and you try to boot with an unmodified diskette in the floppy drive, the translating software does not get a chance to load, thereby rendering the hard drive unreadable. This is generally only a problem if the diskette is infected with a virus. Simply remove the diskette and reboot. The hard drive should boot normally.
This FAQ applies to all Seagate, Maxtor, Quantum ATA 66, ATA 100, and ATA 133 drives.
The faster timing requirements of Ultra ATA/66 and above require the use of an 80-conductor cable. This is necessary for proper operation of UDMA modes 3 and greater. The 80-conductor cable is used with the same connector configuration as the standard 40-conductor cable. The 40 additional conductors are used as ground paths and are all connected to the 7 original ground conductors. These additional ground conductors serve to improve the overall signal quality (signal-to-noise ratio) of the ATA cable. 80-conductor Ultra ATA cables are also limited to a maximum cable length of 18 inches.
If the drive was purchased in a retail kit and not as a “bare” drive, the kit includes an Ultra ATA cable as described here. If not Ultra ATA cables can be purchased from your system vendor or reseller and are fully backward compatible for operation on all standard/legacy ATA devices and hosts. However, these cables will typically utilize the cable select (CS) configuration on ATA drives for defining a master or slave device (drive 0 or drive 1). The drive placement convention used on an 80-conductor cable is also different from the previous generation of cable select type cables. The 80-conductor Ultra ATA cables require the master drive (drive 0) to be installed at the end of the cable and the slave drive (drive 1) to be installed on the middle connector.
The connectors on 80-conductor cables are also color-coded to help ensure proper drive placement and attachment to the host (system). Typical color-coding is as follows: blue for attachment to the host (system), black is for device 0 (master), and gray is for device 1 (slave).
