Solid State Drive Interface Communication Error Count

Is the SSD ultradmacrc error count normal?

The UltraDMACRC error count is the number of data transfer errors that occur when the drive reads or writes data. In most cases, the UltraDMACRC Error Count value should be 0. If the UltraDMACRC Error Count is increasing, then it may be due to an error in data transfer, which may cause problems such as degradation of hard disk performance or file corruption. In general, an UltraDMACRC error count of no more than 100 is considered normal.

However, not all UltraDMACRC error counts are indicative of a hard drive failure, and may be due to other causes, such as software malfunctions or interference with the data transmission line, that require further diagnostic and verification. If the UltraDMACRC error count is increasing and there are no measures to reduce the error count such as changing cables and controllers, replacing the SATA interface, etc., further diagnosis of the hard drive failure or replacement of the hard drive may be required to avoid losing important data.

Lenovo g510 laptop SSD error count

Motherboard poor contact, software false alarm, hard disk quality problems. Lenovo g510 laptop SSD error counting there may be poor contact between the hard disk and the motherboard, software misreporting, or hard disk quality problems and so on. The interface is slightly loose or poor contact, there will be data, you can re-plug the hard disk data cable to make good contact.

What is the impact of a solid state drive interface count error?

Interface count error refers to the hard disk interface out of the data did not pass the checksum, if there is only this error on the hard disk has no direct impact, only on behalf of the data line or the motherboard side of the interface has a problem, generally change the hard disk data line will be solved, but if the combination of the hard disk itself data error, then the problem may be more serious.

Hard disk error count problem

There is a UDC error on the hard disk transfer performance is affected, the main reason is also a problem with the data cable

An analogy. There is a road, the original is 4 lanes of traffic, now become 3 lanes of traffic 2 lanes of traffic, the impact of the big

But there will not be a situation where you worry about data loss

Solution is as follows:

such as SATA disks, with medical skimming cotton swabs moistened with alcohol, wipe clean the hard disk and the motherboard’s interface

Pick up the hard disk for data exchange, to see if the UMC value is still

If you still increase, you should replace the cable, and we recommend using a silver-plated high-purity oxygen-free copper cable with a curved end

If you can’t buy the cable locally, you can contact me and I will introduce you to a place where you can buy a server-grade cable for $4

You’re talking about the boot-up problem that shows Diskerrorpressanykeytorestart. See if

It’s not that you changed the first boot item last time. If it’s not you’ll have to check the hard disk in detail and shield the bad sectors.


Hard drive

A hard drive is one of the main storage media of a computer, consisting of one or more platters made of aluminum or glass. The disks are covered with a ferromagnetic material.

Hard disk has solid state drive (SSD disk, new style hard disk), mechanical hard disk (HDD traditional hard disk), hybrid hard disk (HHD a new hard disk based on the birth of the traditional mechanical hard disk). ssd uses flash memory particles to store, HDD uses magnetic disks to store, the hybrid hard disk (HHD: HybridHardDisk) is the magnetic hard disk and flash memory integrated into the Hybrid hard disk (HHD: HybridHardDisk) is a type of hard disk that integrates magnetic hard disk and flash memory. The vast majority of hard disks are fixed drives, permanently sealed in a hard disk drive.

Head reset energy-saving technology: Saves energy by resetting the magnetic heads during idle time.

Multi-head technology: speeding up a hard drive by adding multiple heads to the same platter for simultaneous reads or writes, or speeding up a disk by utilizing heads on multiple platters at the same time for reads or writes, mostly used in servers and database centers.
