Maintenance of medical equipment computer hard disk failure
The computerization of medical equipment is becoming more and more popular, our hospital has about 20 sets of such equipment, the most common failure is the system application software damage and hard disk failure. Such failures generally require manufacturers to repair or send hard disk back to the manufacturer, time-consuming and uneconomical. We worked out a set of hard disk first backup, failure and then restore the maintenance method, more practical, introduced here to you.
1 maintenance concept
Medical equipment system software or hard disk damage, due to software encryption reasons, generally can not be used to restore the random information themselves. The use of backup utility software such as CHOST, HDCOPY, etc. can achieve a full backup of the hard disk, when the equipment hard disk failure only need to use the backup to restore the entire hard disk, usually can be restored to normal operation.
2 The process of using
Need to have a PC for maintenance purposes, and another backup hard disk, the larger the better, or other backup carriers can also be used, such as CD-ROM burner. Because of the complexity of the hospital equipment, the maintenance of the PC is best installed DOS and WINDOWS
2 kinds of operating system dual boot. In order to prevent software incompatibility, hard disk backup tool is best to install more than a few kinds of software incompatibility can be prevented, the current common CHOST, HDCOPY, etc., often use the CHOST software. Remove the hard disk of the backup device and connect it to the maintenance computer, use CHOST software to backup the whole hard disk, and then reinstall the hard disk back to the original device.
When the medical equipment software failure can not be recovered or hard disk damage, remove the faulty hard disk or use a new hard disk to the maintenance computer, use CHOST software to restore data to the hard disk backup, reinstalled back to the original device, the general equipment can be restored to normal operation. The following is a brief description of the common CHOST software.
3 CHOST's `Use
CHOST now has more than one version, can be divided into DOS and WINDOWS run under the commonly used DOS version, run CHOST.EXE can be installed and used. The specific use is as follows:
3.1 Hard disk backup Remove the device's good hard disk and install it on the maintenance computer, then start CHOST to perform the following steps:
(1) Start the CHOST window and execute LOCAL, DISK, TO IMAGE commands in turn to activate the hard disk image function of CHOST.
(2) In the source disk selection interface, select the hard disk on the original medical device, select the target hard disk, that is, the hard disk used for backup, in addition to setting the image file name, path and other items. The file name should be recorded for different devices.
(3) Click YES, CHOST This process allows you to select the rate of image compression.
3.2 Hard Disk Recovery When a software or hard disk failure occurs in a medical device, install the failed hard disk or a new hard disk into the maintenance computer and use the following steps to recover using the backup file:
(1) Launch the CHOST window and execute the commands LOCAL, DISK, and FROM IMAGE to activate the image file restore function of CHOST.
(2) Use the image file selection window to select the image file to be restored, and select the hard disk to be restored in the pop-up target hard disk.
(3) Click the OK button, CHOST is about to restore the data in the image file, and the restored target hard disk is the same as the backup.
With the above method we have worked on a number of related troubleshooting, although the process also encountered a number of new problems, but most of the last can be solved in the software. At the same time also found that sometimes when the hard disk is damaged inch, with a variety of repair software does not work, in this case the hard disk of the low-level formatting quite useful. Specific tools have the appropriate software and some motherboards come with the low-level formatting function. However, it is important to note that low-level formatting is more damaging to the hard drive, and in fact, a hard drive can rarely be low-level formatted more than five times, so it is important not to use it more than once.
